Method for removal of amine contaminants from liquefied petroleum gas

摘要

A filter and a method of using the filter for removing contaminants from LPG. The LPG enters the filter through an inlet and passes through a first filtration element where chemical contaminants are removed by a chemical entrapping agent, preferably a zeolite. Subsequently, the LPG passes through a second filtration element where particulate contaminants are removed. The invention is also a method of removing contaminants from LPG including the step of routing the flow of the LPG through chemical and particulate filter elements so that chemical and particulate contaminants are sequentially removed.
