Natural gas purification device

Abstract

The invention discloses a natural gas purification device, relates to the technical field of natural gas purification, and provides a natural gas purification device capable of shortening the preparation period. The natural gas purification device is of modulation design, modules are divided according to functions to be achieved, components and parts are integrated into a raw material gas pretreatment unit, a desulfuration decarburization unit, a dehydration unit and a sulfur recycling unit, the units are respectively mounted on pry blocks, the raw material gas pretreatment unit, the desulfuration decarburization unit and the dehydration unit are sequentially connected, and the sulfur recycling unit is connected with the desulfuration decarburization unit. Due to adoption of the modulation design, the modules are divided according to functions to be achieved, the components and the parts are integrated into units mounted on different pry blocks, and the units are respectively manufactured in factories, so that the device is compact in structure and high in integration; after being manufactured, the units are transported to be mounted in natural gas purification plants, so that the on-site mounting time in the natural gas purification plants is shortened, and the influence of weather change is reduced.

Description

technical field [0001] The invention relates to the technical field of natural gas purification, in particular to natural gas purification equipment. Background technique [0002] Natural gas extracted from deposits is a very complex mixture of hydrocarbons with a small amount of non-hydrocarbon impurities. Among them, non-hydrocarbon impurities often contain H 2 S, CO 2 and organic sulfides. Due to the presence of water, these gas components will generate acid or acid solution, causing serious corrosion of gas pipelines and equipment. Therefore, it is necessary to meet the national commercial natural gas quality standards through purification treatment. At the same time, sulfides such as H2S and mercaptans in natural gas are easy to damage the ecological environment and human health after exile, so they can be converted into elemental sulfur for industrial use. This constitutes a basic technical route for natural gas purification and recovery. [0003] All the equipmen...

AI Technical Summary

Problems solved by technology

[0003] All the equipment in domestic conventional natural gas purification plants are installed on site in parts. The construction area is large, the workload is heavy, the construction period is long, and it is easily affected by weather changes, which often leads to repeated delays in the construction period.

Therefore, the problems of traditional natural gas purification stations and factories with fixed equipment, large floor area, poor foundation conditions, long construction period and high difficulty intensity need to be solved urgently
