Small natural gas desulphurization device and application method thereof

Abstract

The invention relates to a small natural gas desulphurization device and an application method thereof and belongs to the technical field of natural gas purification equipment. Natural gas enters a raw material separation device through a natural gas inlet pipeline, enters a natural gas storage box after being separated and purified by the raw material separation device, enters a reaction solutionstorage tank through a natural gas pipeline and reacts with a reaction solution in the reaction solution storage tank, so that a part of sulfides in the natural gas is removed; then, the natural gasenters a reaction tower through a gas pipeline, the reaction solution in the reaction solution storage tank enters an atomization device through a high-pressure pump, is sprayed into the reaction tower by a spraying device after being atomized and is subjected to a secondary reaction with the natural gas, so that sulfur is removed; the reacted natural gas is discharged through a natural gas discharging pipeline after being demisted by a wire mesh demister; the reacted reaction solution falls into the bottom of the reaction tower and enters a regeneration device through a lean amine solution pipeline; the regenerated reaction solution enters the reaction solution storage tank through a rich amine solution pipeline; and the sulfides generated in the regeneration device are collected througha waste gas outlet.

Description

technical field [0001] The invention relates to a small natural gas desulfurization device and an application method thereof, belonging to the technical field of natural gas purification equipment. Background technique [0002] Natural gas is the cleanest, most efficient and convenient energy among primary energy sources. It is not only widely used in industrial and urban civil gas, but also more and more important in the power generation industry. It has shown a trend of rapid development in my country in the past 20 years. From the construction of natural gas pipeline projects marked by the West-East Gas Transmission and Sichuan-East Gas Transmission to the gas shortage in November 2009, the development of the natural gas market has been promoted. The rational use of natural gas and the full purification of natural gas can optimize the energy consumption structure, improve the atmospheric environment, and improve people's quality of life. [0003] Natural gas flows from t...
