回收装置气体吸收塔的设计+CAD图纸

摘要：天然气作为重要的化石能源，其有着优于其他化石资源燃烧后对环境的危害。随着世界经济突飞猛进的发展，越来越多的化石燃料的使用使全球气候与环境变化越来越极端。天燃气是一种十分优秀、十分清洁的化石能源和化工原料，而且使用方便，矿藏量很高的综合经济效益与较低的污染，我国有着丰富的天燃气资源，但燃料气中含有大量的H2S、CO2，约30%左右的天燃气中含有大量硫元素，其中H2S含量大于1%的天燃气储量占到总储量的1/4。H2S的存在不仅会造成设备的损坏和管道的腐蚀，危害人体健康，其燃烧产物也会污染环境，导致温室效应。故我们要将被开采出来天燃气进行净化。而今我们则要制造一种吸收塔用于消除或减少燃料气中的H2S、CO2，以减少燃料气在使用过程中对环境和设备的危害。71922

Design of Gas Absorption Tower for Recovery Unit

Abstract: Natural gas, as an important fossil energy source, has a better environmental hazard than other fossil resources。 With the rapid development of the world economy, more and more use of fossil fuels to make the global climate and environmental changes more and more extreme。 Natural gas is a high quality, very clean energy and chemical raw materials, and easy to use, has a high comprehensive economic benefits, China has a wealth of natural gas resources, but the fuel gas contains a lot of H2S, CO2, about 30% Of the natural gas containing a large number of sulfur elements, which H2S content of more than 1% of the natural gas reserves accounted for the total reserves of 1/4, Mao Yanhong, "high sulfur natural gas purification technology in the application of Puguang gas field" 。 Natural Gas Industry, 2011,31 (5): 99- 100。 The presence of H2S will not only cause corrosion of equipment and pipelines, endanger the health of the human body, its combustion products will pollute the environment。 So we have to be mined out of natural gas purification。 Now we have to create an absorption tower used to eliminate or reduce the fuel gas H2S, CO2, in order to reduce the use of fuel gas in the environment and equipment hazards Zhang Mengyu, Zhong Sheng, Su Wei。 "Progress in Separation of CO2 Adsorbents", Natural Gas Chemical Industry (C1) Learning and chemical)。 2013 Volume 38: 84-88。
