Mol. Sieve Dehydration unit potential problems for LNG plant. AICHE spring meeting, New Orleans USA, April 1 2014

摘要

Treated gas from the CO2 removal unit is chilled against high level Propane refrigerant in the Propane Feed Chillier to reduce the moisture content in the inlet gas feed to the gas dryers, thus reducing the size of the dehydration unit. The wet feed gas undergoes separation of condensed hydrocarbons and water which is accomplished with the Dryer Inlet Separator arranged in series some time with a Dryer Inlet Filter Coalescer prior to entering the Molecular Sieve Dehydrators.
