A wet gas from a field in Iran is processed through two stages of separation; first stage separator operates at 220 psia and 71°F, while the stock tank operates at atmospheric pressure and 69°F. The separator gas condensate ratio is 41,000 scf/STB and the stock tank gas condensate ratio is 450 scf/STB. The molecular weights of the separator gas and stock tank gas are 25.0 and 35.0 lb/lb-mol, respectively. The stock tank condensate gravity is 0.85 and its molecular weight is 125 lb/lb-mol. Let us calculate the specific gravity of the reservoir gas in a step-wise manner, by considering quantities for one STB of condensate. Note that 1.0 bbl is 5.614 ft.

The reactor effluent passes through a condenser that removes essentially all of the methanol and water formed and none of the reactants or inerts. The unreacted reactants and inerts are recycled to the reactor. To avoid buildup of the inerts in the system, a purge stream is withdrawn from the recycle. 100 mol/h of feed to the reactor (not the fresh feed to the process) contains 29.5 mol% CO2, 68.0 mol% H2, and 2.50 mol% inerts. The single-pass conversion of hydrogen is 46.71%. What is the recycle-to-fresh feed ratio?arrow_forward
