Problems solved by technology

However, with the extension of the start-up period, the surface of the packing in the packed tower of the tower desulfurization device is easily blocked by degradation products, forming channel flow, which affects the mass transfer efficiency. In severe cases, the entire flow channel is covered by degradation products, causing the amine liquid to settle down , needs to be shut down for cleaning

Abstract

A complete set of pressurizing and desulfurizing equipment for the top of pressure reducing tower to remove the H2S from its tail gas containing S is composed of pressurizing jet unit, solution tank, circulating pump unit, rich liquid pump unit, and cooler unit. Its desulfurizing technology features that the solution of methyl diethanolamine [(CH3)N(CH2CH2OH)2] is used as desulfurizing agent. Its advantages are high desulfurizing efficiency, simple structure and low cost.

Description

technical field [0001] The invention relates to a desulfurization equipment and its technology, especially a complete set of desulfurization equipment and its desulfurization technology, which is used to remove H in the tail gas with high sulfur content and desulfurization in the refinery. 2 S. Background technique [0002] The 21st century is the century of sustainable development. As an important part of sustainable development, environmental protection has become the focus of people's attention in the new century. Environmental protection is not only related to people's quality of life, but also related to human survival and development. SO in industrial gases 2 and H 2 S is the main cause of acid rain pollution. The effective method is to control the desulfurization content of industrial gases. The Chinese government has paid enough attention to this, and has carried out a number of independent technological researches, and introduced a large number of industrial gas d...
