Abstract

The invention discloses a skid-mounted device for removing heavy hydrocarbon components in natural gas. The skid-mounted device comprises a skid-mounted frame which comprises an upper-layer frame anda lower-layer frame, a first hydrocarbon removing tower, a second hydrocarbon removing tower, a hydrocarbon removing regeneration separator and a hydrocarbon removing regeneration heater are arrangedon the lower-layer frame, and a hydrocarbon removing regeneration gas air cooler is arranged on the upper-layer frame; the tops of the first hydrocarbon removing tower and the second hydrocarbon removing tower are connected with a natural gas incoming pipeline, a branched pipeline is arranged on the natural gas incoming pipeline and connected with the hydrocarbon removing regeneration gas air cooler, the bottoms of the first hydrocarbon removing tower and the second hydrocarbon removing tower are connected with a natural gas outgoing pipeline, and an inlet and an outlet on the hydrocarbon removing regeneration heater are connected with a regeneration cold-blowing pipeline which is connected with the natural gas outgoing pipeline; a communication pipeline is arranged between an inlet of thehydrocarbon removing regeneration separator and an outlet of the hydrocarbon removing regeneration gas air cooler, and an outlet of the hydrocarbon removing regeneration separator is connected with an outer pipeline. The skid-mounted device is of an integrated skid-mounted structure and is small in size, stable in structure and convenient for manufacturing and transporting.

Description

technical field [0001] The invention relates to the field of liquefied natural gas equipment, in particular to a skid-mounted device for removing heavy hydrocarbon components in natural gas. Background technique [0002] With the country's emphasis on environmental protection and the utilization of green new energy, LNG (liquefied natural gas) is getting more and more attention, and the usage of LNG will increase greatly. The main gas sources in my country come from oil and gas fields, coal gas beds, and gas well fields. Such raw gas is not pure and has complex components, especially the content of components above C5 directly affects the ice blockage of the cold box, making the liquefaction of natural gas even more difficult, so the removal of heavy hydrocarbon components in natural gas is very important. [0003] my country's oil and natural gas reserves are abundant and distributed in different ways, but LNG production equipment needs to be reused, that is, after the nat...
