Qatar reactors

These products can be fairly easily processed into high-quality diesel and jet fuel in theory, any source of carbon can be used to generate synthesis gas. These facts along with the growing need for petroleum alternatives have renewed interest in FT synthesis. During the twentieth century, the FT process was used to produce fuels from coal in large and costly reactors. Recently, this megasize approach has been applied to world-scale GTL plants in Qatar. However, to tap abundant biomass resources and stranded natural gas reserves, a smaller scale, yet economically viable, FT process is needed. 

AGC-21 A process for converting natural gas to liquid fuels in three stages generation of syngas in a fluidized bed, Fischer-Tropsch synthesis in a slurry bubble column reactor, and hydrocracking. Piloted in 1997 and proposed for installation in Qatar. 

The H2/CO ratio produced by POX units is often 1.7-1.8 with natural gas as feed. Addition of steam to increase this ratio may not be feasible because the resulting lower exit temperature could substantially increase the amount of carbon formed in the reactor. In some cases the POX reactors may be combined with steam reforming in parallel if a higher H2/CO ratio is required. This combination has been used in a plant for producing hydrocarbons in Malaysia.A similar concept will be used for a large plant that is to produce synthetic hydrocarbons to be located in Qatar. 

A novel high-pressure FT laboratory scale reactor rmit has been designed and commissioned at Texas A M University at Qatar to generate e qrerimental data for vahdation of the kinetic model. This reactor is composed of three major sections gas and liqttid delivery section reactor and product separation section and product analysis section. Figme 3 shows a schematic diagram of the reactor rmit.

The cold and the Demethanizer column section are cooled down and pressurized. Deethanizer vapors are flared at the overhead of Deethanizer reflux drum until Acetylene content is zero in the Acetylene reactor effluent. Effluents are diverted to C2 splitter column and flaring is gradually discontinued. The flaring operation at startup and shut-down typically lasts 7-8 days at QChem s process plants. This is typical of most processing plants in Qatar and elsewhere.
