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.

Figure 2: Conformations of ethane-staggered and eclipsed. The staggered conformation of ethane is a more stable, lower energy conformation than the eclipsed conformation because the eclipsed conformation involves unfavorable interactions between hydrogen atoms.Specifically, the negatively charged electrons in the bonds repel each other most when the bonds line up.n one case, the dihedral angle is 0Â° and the hydrogens on the first carbon line up with or eclipse the hydrogens on the second carbon. When the dihedral angle is 0Â° and the hydrogens line up perfectly, ethane has adopted the eclipsed conformation (Figure 2).
