Our modular gas solution combines both stages of the GTL process into one highly efficient, closely integrated system that provides high levels of volumetric efficiency, safety and reliability.

Illustration of the process

At the heart of the process are two banks of modular reactor blocks. Using an advanced derivative of plate and fin heat exchanger technology, these reactors allow the precise control of heat and gas flow over our proprietary metal-supported structured catalysts, located in a regular array of thousands of closely-spaced channels.

The first reactor uses Steam Methane Reforming (SMR) to convert natural gas into syngas, a mixture of carbon monoxide and hydrogen. The syngas is fed into the second reactor where it is converted via the Fischer-Tropsch process into synthetic crude oil, water and a 'tail gas' composed of hydrogen, carbon monoxide and light hydrocarbon gases.

The close relationship between the two reactors in the CompactGTL process is a vital element in the efficient management of the overall system. The two reactions are tuned to work together to maximise efficiency and minimise waste streams depending upon the specific application and location of the plant. The water produced in the Fischer-Tropsch reaction can be treated to remove impurities and recycled back into the steam reforming process.

CompactGTL's proprietary reactor technology enables the design of a highly self-contained plant operating a stable process that does not require an oxygen supply. The process involves only small volumes of fluids, which proofs the system against wave motion in the offshore environment.
