    Abstract:

    n orderto solve the issueof heavy hydrocarbonfrozen blockingin LNG plant, four process schemes of " adsorption + regeneration gas cooling", " heavy hydrocarbonscrubbing", " gas stripping + heavy hydrocarbon reflux" and " low temperature rectification" are analyzed in detail from the aspects of process simulation, process description, applicability, temperature parameters, liquefaction energy consumption, main equipment, investment and the like, and finally a set of process scheme suitable for heavy hydrocarbon removal in the plant is selected, which is simple in process, low in energy consumption and convenient to operate.
