Abstract

The invention relates to a small mobile skid-mounted natural gas purification device which comprises a feed gas filtration and measurement unit and a deacidification and decarburization unit. The filtration and measurement unit comprises an inlet separator and an inlet filter; an air outlet pipeline of the inlet separator is connected with an air inlet of the inlet filter, and an air outlet pipeline of the inlet filter is connected with a cool air inlet of a deacidification gas heat exchanger. Condensed liquid and solid impurities are removed respectively by wellhead gas through the filtration and measurement unit, the separated and purified natural gas enters the deacidification and decarburization unit, acid gas is removed, and natural gas of which the acid gas is removed enters an activated carbon filter and a lean amine filter to remove the solid impurities to become purified gas. According to the small mobile skid-mounted natural gas purification device, the occupied area is much smaller than that of a fixing technology device with the same treatment capacity; equipment installation is completed in a factory, and on-site installation is easy, convenient and rapid; type selection of equipment for all parts is fixed, standardization production is achieved, and products are stable; the small mobile skid-mounted natural gas purification device can work by moving from one gas source to another gas source; moving and transferring are easier.

Description

technical field [0001] The invention relates to a small mobile skid-mounted natural gas purification device. Background technique [0002] Some gas wells in remote areas have small gas production per well, which is not conducive to or difficult to lay fixed gathering and transportation pipelines. For such gas wells, skid-mounted production is generally used, and wellhead liquefaction is used for trucking and transportation. Wellhead gas needs to be purified before liquefaction to remove acid gases such as hydrogen sulfide and carbon dioxide in the wellhead gas. Generally, in a fixed factory, the purification device is relatively large and there are many equipments, which is not conducive to disassembly and transportation. Therefore, the integration and optimization of the purification device into skids is an important issue in wellhead gas treatment. Contents of the invention [0003] The object of the present invention is to provide a small mobile skid-mounted natural ga...
