HH一sulfide-III硫专用柱测定 低温甲醇洗工艺中酸性气硫化氢和羰基硫浓度的详细资料

低温甲醇洗工艺中酸性气硫化氢和羰基硫浓度
低温甲醇洗工艺中酸性气硫化氢和羰基硫浓度 详细信息:



气化炉产生的粗炉气中仍然含有大量杂质,例如硫化物等,这些有害杂质远不能够满足后续工艺的运行需要的同时也达不到环保要求.此外,水煤气变换单元产生的大量二氧化碳也需进行净化处理.低温甲醇洗工艺的主要原理是将冷甲醇应用为吸收溶剂,从而脱除二氧化碳、硫化氢、羰基硫等多种有害酸性气体.低温甲醇洗技术是一种气体净化的物理方法.

甲醇厂煤制甲醇工艺中,甲醇合成工段对合成气中硫化氢含量控制要求极其严格,要求含量小于0.1×10-6(V/V)。目前用于分析测定气体中硫化氢的方法有天然气中硫化氢含量的测定、亚甲基蓝法、着色长度检测管法、氧化微库仑法测定总硫含量、气相色谱法等。

浩瀚色谱(山东)应用技术开发有限公司选用气相色谱法进行试验讨论,主要从本法测定过程中所涉及的标准气体浓度变化、标气流量、减压阀材质、色谱柱饱和情况等方面,详细讨论从曲线制作到样品测定过程中的影响因素,来方法测定的准确度,以便能正确地指导工艺操作,防止发生合成催化剂中毒等不良后果。

Concentration of acid gas hydrogen sulfide and carbonyl sulfide in low temperature methanol washing process
Acid Gas Hydrogen Sulfide and Carbonyl Sulfide Concentrations in Low Temperature Methanol Washing Process Details:



The crude furnace gas produced by the gasifier still contains a large amount of impurities, such as sulfides, etc. These harmful impurities are far from meeting the operation needs of the subsequent process and also cannot meet the environmental protection requirements. In addition, the large amount of carbon dioxide produced by the water gas shift unit also Purification treatment is required. The main principle of the low-temperature methanol washing process is to apply cold methanol as an absorption solvent, thereby removing carbon dioxide, hydrogen sulfide, carbonyl sulfide and other harmful acid gases. The low-temperature methanol washing technology is a physical method of gas purification .

In the methanol plant coal-to-methanol process, the methanol synthesis section has extremely strict control requirements on the content of hydrogen sulfide in the synthesis gas, and the content is required to be less than 0.1×10-6(V/V). At present, the methods used to analyze and measure hydrogen sulfide in gas include the determination of hydrogen sulfide content in natural gas, the methylene blue method, the coloring length detection tube method, the oxidation microcoulomb method for the determination of total sulfur content, and gas chromatography.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. selected gas chromatography for experimental discussions, mainly from the standard gas concentration changes, standard gas flow, pressure reducing valve material, column saturation and other aspects involved in the determination process of this method. The influencing factors in the process from curve making to sample measurement are discussed to ensure the accuracy of the method measurement, so as to guide the process operation correctly and prevent the occurrence of adverse consequences such as synthesis catalyst poisoning.
