With the advent of new high-temperature high-quality dry-steam, a number of enhanced designs and energy-efficient process-applications have recently become possible.
MHI steam generators are designed for low to high variable steam production to the highest temperatures.
Chemical and Fuel Production Applications: Many steam reactions are beneficial for energy production and biomass. Super-heated steam offers high kinetics and clean chemistry for waste-to-fuel discrete community fuel production. Consider the OAB-4-750 or GOAB-12-800 or the OAB-36 or GHGA. Plastics are hydrocarbons that are made from petroleum, and they can be converted back to liquid fuel. For example, pyrolysis could be used to do this. When subjected to the high heat and pressure, water breaks down the plastic and converts it into oil. An attractive method of converting these waste materials to useful form is anaerobic digestion with steam heating which gives biogas that can be used as a fuel. Waste can also be converted to methanol and ethanol. Garbage can be converted with plasma impact to break down organic materials into syngas, a mixture of hydrogen and carbon monoxide. Organic waste via the Fischer-Tropsch reaction can be converted into Fuel. A mixture of hydrogen and carbon monoxide – from municipal solid waste and other renewable biomass, can be converted to long-chain hydrocarbon molecules that make up diesel and jet fuels. Some of these reactions are discussed below.
For syngas please see reactions below and choose the GHGA model most suitable. MHI offers CO2 (carbon dioxide) and CH4 (methane gas) Airtorch® heaters. Please contact MHI for each.
To help with the COVID-19 process we are encouraging our customers to consider helping front-line workers at hospitals, testing clinics and other health-care facilities in their fight against the coronavirus and the COVID-19 disease it causes with innovative uses of the steam products and Airtorch Products. We have placed many such products in the ‘Sale’ section of the MHI web-store.
High Temperature Steam for Energy Sector and Pharma Sector Use. GHGA Models have independent flow, temperature and pressure controls.
Antimicrobial Applications: Dry high quality low-oxygen steam is a known antimicrobial agent that works without any organic residue. The canning and bottling industry uses a considerable amount of steam. Use for aseptic processing. The productivity increase with the availability of MightySteam™ – high temperature, dry and instant is a remarkable condition for steam – particularly useful for cleaning and soil remediation uses. Please click for steam anti-microbial tutorials and published studies.
Heating Applications: Steam offers heat transfer coefficients that are very high. The heat-content is also very high. Steam dries faster than air above the inversion point. Use one of these generators.
Why is superheated steam far superior to saturated steam? Why is it better at eliminating microbes when above the inversion temperature?
Many bacteria and even viruses thrive in water. Saturated steam can easily contain water droplets which promotes microbe multiplication and even retention. Entropy 2021, 23, 181. https://doi.org/10.3390/e23020181. Superheated steam does not have water droplets. Above the inversion temperature the heat transfer characteristics are great for penetration when using superheated steam particularly above the inversion temperature. This is particularly important for moist food.
Superheated steam deep cleans within seconds. See recent article in Food Control 125 (2021) 107942.
Steam is Antimicrobial (Bacteria, Fungus or Viruses) depending on the temperature and residence time. Click here.
Zero CO2 production cyclic reactions. Please see below.
Power Generation with Condensing Steam. MHI steam 800C+ models for Mega Watts are useful for turning turbines. Remember only the temperature difference is related to the Carnot efficiency. Please contact MHI.
Can steam kill (deactivate) the Caronavirus? It appears so based on the temperature and residence time requirements. As with all antimicrobial uses each condition could be different and testing is required for efficiency analyses. When cleaning surfaces, particular metallic please use steam residence for >280C and adequate residence time. The residence time is time of use, any steam based killing may require at least a few seconds of proper use, just like about 20s are required for hand washing with soap. The higher the temperature the higher the probability of kill. The higher the residence time the higher the probability of kill. Some surfaces can also deactivate bacteria. Test coupons are available.
Typical Applications of Super-heated Steam are Drying, Antimicrobial, Steam-heating, Fuel Production and Chemical Reactions. Improve productivity with steam – use a temperature higher than the inversion temperature. Deep water and energy savings.
Biomass (for electricity generation)
Waste to Fuel (see below)
Sawdust, wood fiber, pulverized coal, wood chips, wood pulp, spruce and birch bark, milled peat, peat for briquettes, Fuel from Waste, Municipal and plant waste. Recycle CO2 by using hot-steam in a fuel cell to make hydrogen and then use airtorch for hydrogen reaction with CO2. So first water vapor and break it down into hydrogen and oxygen -electrolysis at 800C – then use the H2 (g) with CO2 (g) – see reactions below. Burning Fuel gives CO2(g) so the cycle can be completed. Energy use is also seen in electro-chemical power generation with two phase raw materials.
Washing powder, pigment, potassium salt, powdery chemicals, catalysts, coloring agents, regeneration (chemical), carbon activation. It is recognized that the process for turning rubber compounds into usable finished products is vulcanization. There are various types of vulcanization. Most economical is open vulcanization which can take place in hot air or in steam. In the past proper hot steam was not available nor was high-life hot air. Now patented MHI products that offer a wide variety of both steam and hot air and hot process gasses very accurately and with units that have extremely high warranties have changed this landscape. This will help im making synthetic diesel from water, electricity and CO2.

Gasification: Gasification is the conversion of waste materials that takes place in the presence of limited amounts of oxygen – a thermochemical process. Steam or the oxygen in the air is reacted at high temperature with the available carbon in the waste material to produce gases such as carbon monoxide, hydrogen and methane. Gasification processes produce a “syngas” (hydrogen and carbon monoxide) which is used for generating electricity power. Thermal gasification of the waste materials allow the production of a gaseous fuel that can be easily collected and transported. Gasification typically takes place at temperatures from 750-1100°C.
Pyrolysis: This is also a thermal process similar to gasification above which involves the thermal degradation of organic waste in the absence of free oxygen to produce combustible gases. Pyrolysis uses heat to break down organic materials in the absence of oxygen e.g with steam heating to 1250C. Materials suitable for pyrolysis processing include coal, animal and human waste, food scraps, paper, cardboard, plastics and rubber. The pyrolytic process produces oil which can be used as a synthetic bio-diesel fuel or refined to produce other useful products. Sometimes the byproduct of pyrolysis is a kind of fine-grained bio-charcoal called “biochar”, which retains most of the carbon and nutrients contained in biomass so can be used as a soil enhancement to increase soil productivity. During Pyrolisis volatile gases are released from a dry biomass at temperatures ranging up to about 700C. These gases are non-condensable vapors such as CH4, CO, CO2 and H2, and condensable-vapor of tar at the ambient temperature. Cellulose can break down into Char, H2O, CO2 and methane.
Combustion: Use the Airtorch+Steam combination for a clean most common and well-proven thermal process using a wide variety of waste fuels. Municipal and household waste is directly combusted in large waste to energy incinerators as a fuel with minimal processing known as mass burning. Combustion can be with a solid, liqid or gas reactant with oxidation. The Boudouard reaction (solid combustion) is stable above 700C to eliminate CO2 because CO2(g) + C = 2CO(g). Above 700C one can use CO(g) as a reductant for oxides as is done for iron oxide reduction. Link to MHI Fluidized Bed Designs.
Digestion: Landfills are the primary method of disposal of municipal solid waste and if left undisturbed, landfill waste produces significant amounts of gaseous byproducts, consisting mainly of carbon dioxide and combustible methane (CH4). This landfill gas or bio-gas is produced by the (oxygen-free) anaerobic digestion of organic matter. Treatment by steam is often recommended for elimination of certain harmful bacteria. Anaerobic digestion to produce bio-gas can either occur naturally producing a landfill gas, or inside a controlled environment like a biogas digester. A digester is a warmed, sealed, airless container where bacteria ferment an organic material such as liquid and semi-solid slurries, animal wastes and manures in oxygen-free conditions for bio-gas. An advantage of anaerobic digestion for converting waste to energy fuel is that it employs semi-solid or wet waste. This is normally a small scale operation. The bio-gas produced can be burned in a conventional gas boiler to produce heat or as fuel in a gas engine to generate electricity or fuel some of the farm vehicles.
Fermentation:Fermentation uses various microorganisms and yeasts to produce liquid ethanol, a type of alcohol, from biomass and bio-waste materials. The conversion of waste to energy by fermentation requires a series of chemical reactions to produce the ethanol bio-fuel. Here steam can be directly introduced for rapid kinetics. Multiple reactions occur. The first reaction is called hydrolysis, which converts organic materials into sugars. The sugars can then be fermented (similar to making alcohol) to make dilute ethanol, which is then further distilled to produce a bio-fuel ethanol.
Typical high temperature steam i.e H2O(g), CO(g) and CO2(g) reactions for consideration for CO2 removal (one atmosphere) or for making H2 (gas).
CH4(g) + H2O(g) = CO(g) + 3H2(g) Steam Reforming above ~750C. The opposite direction reaction is sometimes called the Fischer-Tropsch process. Selective liquid fuel formation is possible with the MHI Airtorch(R) or Insta-Steam Units. Contact MHI for details.
Combination of Greenhouse gasses (also called high temperature greenhouse gas reactions):
CO2(g) + CH4(g) = 2CO(g) + 2H2(g) Feasible above ~650C or via the steam reforming and water shift shown above.
2CH4(g) + H2O(g) +CO2(g)= 3CO(g) + 5H2(g) Well feasible above ~(750-850C) with easy methods for enabling all forms of downstream reduction. MHI reaction.
E.g. products that are reducing gases that can be used for various reducing reactions including cleaning and shiny metal production such as Fe2O3 + 3CO(g) = 2Fe + 3CO2(g) (weak) or Fe2O3 + 3H2(g) = 2Fe + 3H2O(g) above 515C. Note also that CO2(g) + CH4(g)=2C + 2H2O(g) is always feasible at >100C but is extremely weak. Fe2O3 + 2CO(g) + H2(g) = 2Fe + 2CO2(g) + H2O(g) is always feasible but best above 1000C.
It appears that the worst greenhouse gases methane can be converted to non-greenhouse gases CO and H2. These reducing gases can be used for reducing some metal oxides. So either the OAB or Airtorch may be used. At this point catalysts become become important.
Note that several gases can be toxic and only professional involvement is recommended.

Energy Saved for Laundry or Garment pressing. Car seat Pressing. Laundry Use. The energy requirement is approximately 0.15 – 0.30 kWh / kg of linen (source http://www.rabc-wfk.com/module3/Module3_EN.pdf). This is a good number for dry-cleaning but for full steam drying it may be best to use a number like ~1kWh per /kg. If you are using and paying operationally for a 300kW boiler (1,024,327 BTU/hr) (or 30BP); are you dry-cleaning 900 kg (close to a ton of linen) of laundry in an hour? If this is not so please consider OAB instead to save energy. The cost of energy is similar whether gas or electric. Click here for savings from energy efficiency. Garment dewrinkle, heatsetting and textile conditioning in a raoid energy efficient manner.
Seats pressing in rapid demand operations like automobile seats manufacture. At 10 cents per kWh a 300 kW boiler operational cost could be as high as $30 an hour. A 10 kW OAB machine reduces this payment to ~ $1 per hour. Many electric companies offer grants to make capital changes with energy efficient new machinery. Whether a 12 kW OAB may substitute for a 300 kW boiler depends on the application. Most applications where a high velocity jet is required can be met by the OAB® .

Heat Processing to make cheese is varied the type of technologies used in practice. The time and temperature programme for heating is determined by the method of heating and the type of cheese. Some cheeses require heating to temperatures above 40°C-56°C (133°F) Normally at 37 – 38°C the activity of the mesophilic lactic acid bacteria is retarded. Time is taken check the acidity, Above 44°C or more the mesophilic bacteria are deactivated, and they are killed if held at 52°C between 10 and 20 minutes. Heating beyond 44°C is typically called scalding. Some types of cheese, such as Emmenthal, Gruyère, Parmesan and Grana, are scalded at temperatures as high as 56°C (133°F) . Some of the most heat-resistant lactic-acid-producing bacteria survive this treatment e.g. Propionibacterium freudenreichii ssp. shermanii“.

Continuous Superheated Process Steam for Odor Removal and Other Uses. Carbon Activation. Superheated steam can be used for physical/chemical activation of carbon resulting in enhanced nanoporous and porous structures of carbon ( about 10-(50-80) nm). The resultant carbon is called activated. It is higly porous and activated. This nanoporous/mesoporous microporous structure is expected to enhance the removal of toxic hydro-carbons and other dangers from waste water/water works and from gas. Continuous steam temperature that is required is greater than ~800°C and dry. Please consult MHI for known techniques for start-up of carbon containing canopies or drums. One important requirement for this is the availability of instantaneous steam, within minutes because moisture if present tends to clog pores. The OAB-4 system or the OAB-12 system makes instantaneous steam. Please see video on Videos and Media Gallery.
Electric Superheated Steam. What is the difference between Disinfection and Sterilization? See box below.
Steam temperatures greater up to 1300C.
Steam Sanitation: Studies have shown that even 1 second of residency time of 248°F (120°C) steam is roughly 97% effective against common strains of bacteria1. In controlled experiments, higher temperature steam requires lower residency times to achieve effectiveness. This result most likely follows the common law of chemical kinetics where speed increases exponentially with temperature.
What is the difference between Disinfection, Sanitizing and Sterilization? Sterilization vs. Disinfection vs. Sanitation
There are 3 fairly commonly accepted levels of “clean” in many industries. Sterilization refers to the statistical destruction and removal of all living organisms. Disinfection generally refers to inanimate objects and all vegetative cells, but not spores. Sanitation refers to the reduction of microorganisms to levels considered safe from a public health viewpoint. The official definition of sanitation, according to the Association of Official Analytical Chemists, for food product contact surfaces is a 99.999% (5-log) reduction of contaminants in a 30 second period. For non-product contact surfaces, a 99.9% (3-log) reduction in contamination is necessary. What is anti-microbial cleaning?Sterilization requires 6 to 12 log or more cleaning potency mostly done in steam sterilizers that are approved for this purpose. the antimicrobial market has been largely comprised of chlorine (bleach), ozone, quaternary ammonium compounds (quats), per-acetic acid (PAA), formaldehyde and glutaraldehyde (aldehydes), and hydrogen peroxide. All of these technologies have limitations in addressing sanitization and disinfection needs.Steam is powerful. Se Patents Other published patents have shown superheated steam can clean upto sterilization levels. Patent numbers 8,940,245, 8,945,468, 8,652,403, 8,435,459 and many others that are available.

Why is Steaming Better than Boiling for Food:Steaming is preferable to boiling in some cases, because there is no loss of mineral salts nor food substances. The flavor is not so likely to be lost as when food is boiled. Some delicate fish is best cooked by steaming as it does not break up as it might in boiling water. Vegetables prepared in this way prove very palatable, and very often variety is added to the diet by steaming bread, cake, and pudding mixtures and then, provided a crisp outside is desired, placing them in a hot oven to dry out the moist surface.
Did you know the cost of steaming with superheated steam is less than 0.1 UScent per dumpling.

Design with GHGA or OAB® Steam and Hybrid Tunnels. THE GHGA can provide high temperature steam up to 900C (can be set as required), pressure can be automatically adjusted and steam rate can be adjusted.
Traditional boilers yield saturated steam (Tsat and Psat are linked). Note that Steam generators do not have to operate at high pressure for the high temperature. They work at 1 Bar safety. Thus one can get high temperatures without unwieldy pressures – with a steam generator. For example with a boiler one needs a high 10 Bar and even then the saturation temperature is only 180°C -even at 100 Bars the saturation temperature is only 311°C.
Steam generators operate routinely at 300°C, i.e. well above the inversion temperature. If the steam is for heating purposes, please compare the enthalpy and you will be surprised. If the steam is for work purposes please use the work potential row below, the work potential increases with both temperature and pressure. Work potential is measured from 25°C base temperature.
The cost of boilers increases for very high pressure ratings. Traditionally the steam generators offer 95%+ efficiency – boilers could be much lesser and also loose efficiency with pressure ratings. However even at 100 Bars the saturation temperature is only 311°C. Again a fairly easy and routine temperature from the OAB type steam generator.
1 Bar =100000 Pa = 14.5 psi, 10 Bar =1000000 Pa =145 psi, 100 Bar = 107 Pa = 1450.3 psi
