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.

The deethanizer (DER) operates at about 450 psia and. separates ethane from the propane and heavier components. Because. the critical temperature of ethane is about 90 oF, the condenser of the. deethanizer must be refrigerated.
