Gas processing (Mokhatab et al., 2006) consists of separating all of the various hydrocarbons and fluids from the pure natural gas (Figure 5-1). Major transportation pipelines usually impose restrictions on the
In the commercially available coal gasification plant, the synthesis gas was created using a Rectisol scrubber and a shift conversion. The second pilot plant produces methane by using converted synthesis gas to extract it from naphtha. Table 8. An overview of thermochemical methanation plants in ...
The sulfur dioxide can be removed from the waste gases by smokestack scrubbers which increase economic costs and leave the problem of what to do with the large volumes of solid scrubber waste. An alternative to smokestack scrubbers is to burn coal with a lower sulfur content. Low-sulfur coal...
In a flash column, to reduce the loss of methane to the off-gas stream from the water scrubber, the pressure is reduced to 3 bar. On exiting from the scrubber’s bottom, wastewater is fully saturated with H2S and CO2 and a little quantity of CH4 which is restored and reversed back to...
