Optimising Hydrogen and Chemicals Production from the Transport Gasifier™
The KBR Transport Gasifier™ is an advanced circulating fluidized bed reactor. It is designed to operate at high solids circulation rates and gas velocities, giving improved mixing, high mass and heat transfer rates, and high throughput. This advanced coal gasifier has been tested and proven at the Power Systems Development Facility (PSDF) in Wilsonville, AL.

KBR's Transport Gasifier (TRIG™) – An Advanced Gasification Technology for SNG Production From Low-Rank Coals
The KBR Transport Gasifier, also known as TRIG, is an advanced coal gasification technology that provides clean, particulate-free syngas for a wide variety of coal-based chemicals and fuels applications. In this paper, the new KBR TRIG Coal-to-SNG process is described, in which the TRIG gasifier is integrated with a conventional methanation scheme, producing about 150 million standard cubic feet per day (mscfd) of SNG from two representative low-rank coals that are abundant in the U.S.A. and worldwide. The paper further discusses the process scheme development, integration and optimization elements that build on the unique attributes of the TRIG gasification system to produce an efficient and technically robust SNG plant design.

New KBR Process for Coal to Ammonia
Ammonia, the most widely used intermediate for making fertilizers, is usually manufactured by the catalytic steam reforming of natural gas. Natural gas has one of the highest proportions of hydrogen among all fossil fuel feedstocks. Hence, from an efficiency standpoint, natural gas is an ideally suited feedstock for the manufacture of ammonia. However, with increasing natural gas prices, coal gasification can be an economically viable alternative route.
