摘要
Abstract
The proportion of C 5+ heavy hydrocarbon and component of natural gas is different because of its region. Heavy hydrocarbons owing to the lower melting and boiling point than methane, if not removed completely, will lead to the frozen blocking phenomenon of the pipeline, valve and equipment in the natural gas liquefaction process, which will result in the economic losses or safety accidents. Take the heavy hydrocarbon removal process of a small LNG plants as an example in this paper. The causes of heavy hydrocarbon ice blockage in the heat exchanger are analyzed. The removal mode of"Heavy hydrocarbon washing & Low temperature cold desorption"is selected and applied in the heavy hydrocarbon removal process transformation. The renovation was finished in the end of 2015. Up to Jan. 2016, working hours of this LNG plant have totaled up to about 3000 h and frozen blocking has never happened. This new system runs extremely stably. The research has certain guiding significance for the transformation of heavy hydrocarbon ice blockage in liquefaction process.关键词
