4. Fifty MMscfd of a sour (35 vol% CO2, O vol% H2S) natural gas enter a remote amine unit at 1000 psia and 100F. a. Estimate the water content of this gas. b.This produced gas (SG 0.7) leaves the amine contactor at 990 psia and 130F with 2 vol % CO2 (assume saturated with water as the amine contactor has a water wash at its top). How much, if any, make-up water (in gpm) is needed? State any assumptions. c. It is suggested that this treated gas be fed into a sales pipeline. While flowing in the pipeline the temperature and pressure are expected to drop to 50F and 500 psia, respectively. Do you approve or oppose this suggestion? Support your answer with appropriate calculations. d. What processing and what specifications would you recommend to ensure trouble-free pipelining of the gas
