Assuming pure Ethane, dew point temperature at 20 bar suction pressure should be around -10 deg C or so. With an inlet gas temperature to compressor of 10-15 deg C, it maybe doable with one compression (thermodynamic) stage depending on poly-tropic efficiency of the compressor.ssuming pure Ethane, dew point temperature at 20 bar suction pressure should be around -10 deg C or so.

Recall from Part III that ethane has about 66,500 BTU/gallon. If we multiply by 42 to get BTU/Bbl, that yields the BTU factor in the above table. (2,790,000 BTU/Barrel or 2.79). If we divide the price of ethane on a per barrel basis by the BTU factor, weâll get the price of ethane on an MMBTU basis.(0.46 * 42) / 2.79 = $6.92/MMbtu. Obviously thatâs a lot higher than the price of natural gas at $2.00 /MMbtu. But that number pales against natural gasoline.f we multiply by 42 to get BTU/Bbl, that yields the BTU factor in the above table. (2,790,000 BTU/Barrel or 2.79).
