Abstract
The process for liquefying a gaseous stream received from a pipeline that is comprised predominantly of ethane and a relatively small amount of other components by using a mixed refrigerant loop incorporating heavy hydrocarbons (butane, and/or pentane), as well as a distillation column to remove constituents lighter than ethane. Prior to cooling in a main heat exchanger, the gaseous stream is split into two fractions. The first fraction is cooled in the main heat exchanger and introduced to the distillation column. The second fraction is expanded to produce a two phase fluid, with the liquid fraction being introduced to the distillation column below the first fraction, and the gas fraction being cooled and then introduced to the distillation column at a point above the first fraction.
