半水煤氣有機(jī)硫脫除技術(shù)改造的初步方案
[Abstract]:In the production of synthetic ammonia, crude raw gas can be obtained by various processes, but the crude raw gas can contain a certain amount of sulfides. The existence of sulphide has a great influence on ammonia production. In order to ensure the long period and stable operation of the system, it should be removed to meet the requirements of the process. By following up the desulphurization section of ammonia semi-water gas system in Gansu 脳 脳 Chemical Co., Ltd., and consulting the operators and technicians, the author is familiar with the technological process of the desulfurization section of the semi-water gas system of Gansu 脳 脳 Chemical Co., Ltd. Some technological parameters are obtained. The wet desulfurization series dry desulfurization process is adopted in the desulfurization section of the semi-water gas system. The organic sulfur content of the half-water gas desulfurized by wet desulfurization is relatively high, and the removal of organic sulfur completely depends on zinc oxide, which leads to the frequent replacement of zinc oxide. Therefore, this paper takes the problems existing in the operation of the desulfurization section of the semi-water gas system as the research object, through consulting the relevant information and consulting the technicians, on the basis of the existing desulphurization equipment. According to the semi-water gas desulphurization system, the following technical retrofit scheme is put forward. In this scheme, a set of organic sulfur hydrolysis unit at room temperature is installed between the primary outlet separator and the secondary inlet buffer of the low-pressure machine, and the process design and calculation of the unit and its auxiliary equipment are carried out. The calculation results show that the existing zinc oxide desulphurization unit can be extended to 4.26 times as long as the original life cycle.
