一、一般情况兴平化肥厂是我国第一个采用重油为原料的中型合成氨厂。在第一期工程中,除由我国自行设计的精制化工装置(包括低温变换、二次脱硫脱碳、甲烷化),合成、硝酸、硝铵以及锅炉等化工设备外,尚有一部分设备是引进的,包括重油汽化工段,中温变换砷碱液脱硫脱碳及部分转动设备。第二期工程是在总结第一期工程的运转情况基础上加以改进的,其规 First, the general situation Xingping Fertilizer Plant is the first medium-sized ammonia plant using heavy oil as raw material. In the first phase of the project, in addition to China’s own design refined chemical plant (including low temperature transformation, secondary desulfurization decarbonization, methanation), synthesis, nitric acid, ammonium nitrate and chemical equipment such as boilers, there are still some equipment is the introduction , Including the heavy oil vaporization section, temperature shift arsenic lye desulfurization and decarbonization and some rotating equipment. The second phase of the project is to improve the operation of the first phase of the project based on the situation, and its regulation
