1. Estimate the MEA circulation rate and the sizes of absorber and stripper for an MEA sweetening plant for the following design conditions:
All working must be shown
1. Estimate the MEA circulation rate and the sizes of absorber and stripper for an MEA sweetening plant for the following design conditions:
– Inlet gas flow rate, Q = 110 MMscfd
– Inlet pressure = 550 psig
– Inlet temperature = 105 deg F
– Acid gas content:
H2S = 3.8 mole %
CO2 =2.9 mole %
– Inlet gas SG = 0.75
– CO2 in treated gas = 0.1 mole %
– H2S in treated gas = 0.25 grain/100scf
2. the working needs to be shown
In this assignment you will need to perform an analysis on a hypothetical discovery based on the following information:
Field Size: 1.4 Tcf
Production/Reserve Ratio 7% of the original field size starting producing year 3
Gas price: $3.5/Mcf
CapEx: $1/Mcf capitalized in 5 years, straight-line depreciation
Operating Cost: $0.8/Mcf
Royalty: 10%
Government Take: 40%
Cost recovery limit: 60% of gross revenue
Discount rate: 10%
Income tax rate: 33%
Allow cost recovery carry forward.
1. Evaluate the discovery – you need to calculate the total worth, worth to the company, government take, value in terms of entitlement interest and working interest.
2. Evaluate the producing gas reserve – total worth, wor
