Solids Gasification

Decarbonization And Climate Protection: Green Syngas And Chemicals

With our unique portfolio ranging from large-scale solids gasification and water electrolysis to downstream applications, we can enable carbon-reduced or even completely CO₂- free value chains. All from a single source.

The Hydrogen Landscape — The diagram serves as an example only. Other routes, such as for DME, gasoline, ethylene or acetic acid, are also possible.

A clean and efficient pathway from feedstock to product

Environmental protection is becoming increasingly important. Based on our uhde^® gasification process we can design and implement optimized process chain solutions from a single source.

High-value products and by-products

The main product of gasification processes based on our uhde^® entrained flow gasification (also known as PRENFLO) technology is syngas. Thanks to our unique portfolio, which is complemented by various downstream processes, we can offer you complete end-to-end solutions.

Alongside the main products, the by-products of our gasification are also valuable. The slag can be used in road-building, fly ash is used in the cement industry, and sulfur or sulfuric acid can be readily recovered and marketed.

Multifuel capability

This special feature allows the co-feeding of liquid and gaseous feedstocks.

uhde^® entrained-flow gasification - one technology, maximized feedstock flexibility

Reduced operating costs

Use of low-value feedstock or waste

Higher-value products, e.g. methanol, ammonia, urea, DME, SNG, jet fuel, gasoline/LPG, diesel/naphtha, hydrogen, waxes

Environment-friendly solutions

High electrical efficiency in power generation

Multifuel capability

A basis for carbon capture and storage/utilization (CCS/CCU)

Gasification processes offer a number of upstream and downstream advantages to customers with access to solid feedstocks, and dwindling energy reserves as well as a need to meet increasingly stringent environmental requirements. With proper preparation a variety of carbon-based materials can be easily gasified to produce synthesis gas (syngas) for the subsequent production of chemicals, liquid fuels, electricity or direct reduction gas (DRI). Gasification is particularly clean and efficient.

Gasification is also flexible with respect to feedstock quality and the use of mixed feedstocks. The gasification of low-value or waste materials is an attractive option. Even otherwise problematic materials can be gasified together with the main feedstock.

Gasification technology offers environment-friendly, efficient solutions for these applications. In power generation, for example, gasification can achieve high electrical efficiencies and also forms a basis for Carbon Capture and Storage (CCS) or Carbon Capture and Utilization (CCU).

The selection of the end product is analyzed in the concept phase and is influenced by various factors, such as feedstock to be used, targeted sales market, owner structure, financing model, CAPEX and OPEX expectations, availability of required partners, emissions and environmental conditions, possibilities in terms of CCS/CCU, local incentives, strategic and political importance.

Common applications are to be found in the chemical and refinery fields, and in isolated cases also in power generatins and now increasingly in waste-to-energy.

Some examples are given below, with the X standing for various feedstocks such as biomass, waste, other carbonaceous feedstocks or feedstock combinations.

Waste-to-energy

The conversion of lignocellulosic biomass, such as straw, forest waste or dedicated energy crops into high-valuable chemical products ot high-quality advanced biofuels and naphtha or methanol is becoming more and more important.

The process chain with its individual technology links forms the key foundation for the further development of a plant and its cost efficiency. However, successful realization depends on the choice of a suitable and experienced EPC contractor.

As a process-oriented EPC contractor with over 2,500 plants built, we can meet both roles, that of technology provider and integrator, and that of EPC contractor. This means that our role and responsibility in a project can be tailored completely to the requirements of the client.

The same applies to the scope of work, which can extend from a conceptual or feasibility study to a license and basic engineering package for individual technologies or technology chains to front-end engineering and EP/EPCM/EPC.

With 100 years of experience in chemical engineering and global project execution, we are a reliaby life-cycle partner for our customer.

Since the early twentieth century tkIS has been making a key contribution to the chemical conversion of carbon-containing solid and liquid feedstocks into high-value synthetic products. This has been carried out both in cooperation with third-party technology providers, such as Texaco and Shell, and independently. In the course of time we have gained experience with eight different gasification technologies:

Texaco oil gasification TGP (today GE)
Texaco coal gasification TCGP (today GE)
Shell oil gasification SGP
Shell coal gasification SCGP
Koppers-Totzek solids gasification
Winkler solids gasification
High-Temperature Winkler solids gasification
PRENFLO^® solids gasification* with Heat Recovery (PSG) and with Direct Quench (PDQ)

In total we can look back at more than 100 plants built.

*now known as uhde^®entrained-flow gasification
