About SES
Flexible, efficient and economic: SES Gasification Technology (SGT) produces synthesis gas. Synthesis gas or “syngas” is a clean and incredibly versatile source of energy. SGT is uniquely capable to manufacture clean syngas from a wide variety of natural and renewable resources such as most all forms of coal, biomass, municipal solid waste (MSW), and refuse derived fuels. Syngas from SGT allows SES’s customers to cleanly unlock the value from their local and affordable resources and transform the syngas into electricity, steel, fuels, chemicals, fertilizers, or to be used as a natural gas substitute. This proprietary fluidized bed technology was built on decades of research, development, demonstration and commercial operation and is implemented in multiple plants in China. The management professionals of SES, many hailing from Fortune 100 energy companies, are among the most qualified gasification experts in the world.

Our Mission
SES is dedicated to deploying world-class SES Gasification Technology (SGT) into projects globally to allow our and our customers' projects to maximize profits and minimize the impact on the environment through generating clean energy from the most affordable and accessible solid fuels.
How SYNGAS is Used
SES is advancing its economical cleaner coal power solution with iGAS: global syngas-to-power IGCC projects that incorporate SGT with GE’s aero-derivative gas turbines.
Clean and economically advantaged, SGT produces syngas which is an inexpensive, eco-friendly replacement for imported natural gas for use in industrial settings in regions that are gas-poor.
SGT syngas generated from coal can be converted into methane, the key component in natural gas, to produce substitute natural gas (SNG) and sold directly into the natural gas pipeline systems.
SES, with global partner Midrex Technologies/Kobe Steel, is advancing a next-generation Direct Reduced Iron (DRI) solution for steel production that combines SGT with industry-leading Midrex’s MXCOL® DRI technology.
SGT produces clean syngas, an economically advantaged alternative to natural gas. Its uses range from manufacturing myriad chemicals to ammonia for fertilizers, critical to sustainable food sources.
SGT is an excellent fit for large-scale Coal To Liquids projects, to produce diesel, jet fuel and gasoline, in regions where crude oil is scarce or expensive or refining capacities can’t meet demand.

Global Need and Resources
Energy poverty is a reality, as is the need for improved access and energy independence for the world's developing nations. To support their GDP growth, newly industrialized countries require an increase in their energy supply and reliability.
Imagine the challenges of a nation trying to industrialize with limited access to affordable natural resources. Unreliable electricity for homes and businesses; low crop output; low availability of acceptable building materials; and rudimentary medical care. These are realities for many in the world.
To bring positive change to these regions, affordable energy sources that are also clean and efficient need to be implemented. Significant investment in new plants, and retrofits of existing plants with newer, cleaner technologies, are needed to alleviate energy poverty and raise the standard of living.
The Future of Gasification
-
Products
Clean energy and distributed power for the developing world is projected to tip the commercial scale of gasification from its six-decades-plus focus on chemicals, currently at approximately 60% per the Gasification and Syngas Technologies Council. -
Geography
Developing and newly industrializing regions with vast low-cost coal natural resources yet no or limited indigenous natural gas – led by China, and including India, Southeast Asia, Eastern Europe and South Africa – are driving demand, versus developed regions like the U.S. with abundant natural gas reserves. -
Technology
The gasification technology industry is expanding its share of scope beyond license and equipment to include turnkey gasification islands, and sales of syngas for industrial fuels, substitute natural gas direct to pipeline, and syngas distributed power sales.
SES Gasification 101
Gasification is a building block technology for the manufacturing of chemicals, electricity, fuels, and other valuable energy products that have conventionally been produced from natural gas or crude oil.
Air Separation Unit
(ASU)
The Air Separation Unit, or ASU, brings in air from the outside and uses a specialized process to separate the oxygen from the air. This purified oxygen stream is fed to the gasifier to drive the reactions.
Gasification
In the Gasification Section, coal is combined with oxygen in the gasifier to generate syngas. The non-reactive parts of the coal feed are removed from the bottom of the gasifier as an ash by-product. This can be sold for use in road paving or making cement.
High Temperature Heat Recovery
In the High Temperature Heat Recovery section, the hot syngas is cooled while generating high pressure steam to improve the overall efficiency of the plant. This steam can be used to generate electricity or to provide thermal energy.
Fines Recycle
In the Fines Recycle section, any remaining solid particles that are still in the syngas are removed. The fines are collected and returned to the gasifier to minimize solid waste and to improve overall efficiency.
Sulfur and CO2 Removal
In the Sulfur and CO2 removal section, the syngas is processed to remove any sulfur and CO2. Since the sulfur and CO2 are removed prior to combustion and while the syngas is still at elevated pressure, very deep removal is easily achieved. The technologies that are used to capture the CO2 and sulfur are fully mature, commercially proven technologies that have been used for decades in the gasification and refining industries.

Gasification is a combination of molecular chemical reactions that convert complex hydrocarbons and lower value energy sources such as coals, municipal solid wastes (MSW) and biomass materials into synthesis gas, or “syngas,” which is generally defined as hydrogen (H2) and carbon monoxide (CO) molecules. These syngas molecules are the building blocks for numerous and varied products, such as electricity, fuels and other high value energy products, and chemicals and precursors that have conventionally been produced from natural gas or crude oil. Gasification is an economic and efficient way to manufacture these products from locally abundant and affordable natural resources or MSW.
A gasifier is the vessel in which the reactions occur to chemically convert hydrocarbon resources into syngas. Generally gasification takes place under pressure, ranging from atmospheric conditions to as high as 55 bar(g). Gasification requires a limited amount of oxygen, less than combustion, as the resulting chain reactions are more thermally efficient with a balance of exothermic and endothermic constituent reactions. Generally the reaction temperatures required for gasification range from 900-3000°F (480-1650°C). Steam or water and an oxidant plus the hydrocarbon source are required for the gasification reactions to occur and be sustained.
Products and by-products of gasification include syngas – gaseous form of hydrogen (H2), carbon monoxide (CO), carbon dioxide (CO2), water (H2O), methane (CH4), hydrogen sulfide (H2S) and COS (if sulfur is present in the original feedstock), nitrogen (N2) and other compounds in reduced quantity – ash, heat, and water.
The gasification process is fundamentally clean and environmentally friendly, as it deals with reactants and product species in their lowest molecular form. Complex organic feeds are reduced to simple molecules, with metals and other non-organic trace impurities vitrified in the ash by-product which may be safely disposed of or resold. Downstream processing of the syngas is often simple and cost-effective as waste products have already been removed.
The syngas produced from gasification is the replacement for natural gas and crude oil for the formation of a plethora of energy and chemical products. When low-cost feedstocks are available and used for conversion, these products are economically competitive with products derived from natural gas and oil and often have a lower environmental footprint.
