Introduction

The adjustment of energy composition is one of the highlights of my country's economic structure adjustment. Among the many countermeasures taken for this purpose, the most realistic and effective is By greatly increasing the proportion of natural gas in the energy composition, it will become the most effective way to reduce the proportion of coal consumption, improve energy efficiency and reduce environmental pollution. "Gripper". Since entering the 21st century, China's natural gas industry has achieved rapid development, but compared with the requirements of the rapid development of the national economy, Compared with the natural gas industry in the world, there are still big gaps and problems in the development of China's natural gas industry. Improve my country's natural gas production technology, healthy The complete set of technical standards is an important measure to boost the rapid development of the natural gas industry. GB/T 35212 "Gas and Solution Analysis of Natural Gas Treatment Plant" "Analysis and Evaluation Methods for Desulfurization, Decarbonization and Sulfur Recovery" series of standards are designed to standardize natural gas purification and production activities and ensure efficient natural gas production.

The technical standardization document proposed by the production, is intended to be composed of three parts.

--- Part 1. Gas and solution analysis. The purpose is to establish a common, actionable analysis for natural gas processing plant gases and solutions Evaluation method.

--- Part 2. Analysis of solvents for desulfurization and decarburization. The purpose is to establish an actionable analysis for the desulfurization, decarbonization solvent of the natural gas treatment plant Evaluation methods and corresponding technical requirements are specified.

--- Part 3. Technical requirements and analysis and evaluation methods for sulfur recovery and tail gas treatment catalysts. Designed for natural gas treatment plants Sulfur recovery and tail gas treatment catalysts established operational analysis and evaluation methods, and specified corresponding technical requirements.

This document is the 3rd part of this series of standards. This document specifies the sulphur recovery and tail gas treatment processes for different natural gas treatment plants.

Corresponding catalyst technical requirements and analysis and evaluation methods. The natural gas treatment plant uses sulfur recovery and tail gas treatment to achieve sulfur recovery and emission reduction The process of natural gas has become an important part of the natural gas treatment process, and the selection of a series of sulfur recovery and tail gas treatment catalysts is the The core of class crafting. Under the dual requirements of large-scale sulfur recovery and increasingly strict environmental regulations, natural gas treatment plants should The composition of feed gas, different process routes, and different catalysts for sulfur recovery and tail gas treatment are selected, so as to be economical, reasonable and reliable, and meet the national requirements. domestic sulfur dioxide emission requirements. This document will provide the basis for the selection of corresponding catalysts for the sulfur recovery and tail gas treatment processes of natural gas treatment plants.

According to the report, it provides technical support for natural gas treatment plants to save investment, reduce consumption, improve the overall operation capacity of the device, and meet the requirements of environmental protection.
