In view of the above problems and to give birth conditions close to fantasy status scale conditions as the evaluation basis by setting equipment, furnishings, methanol respectively equipment, an increase of hydrogen accept assembly, chosen on merit and accurate application of catalyst, methanol process conditions optimization, a total of four aspects, put forward promotion capacity detailed measures and methods for methanol decomposition. In methanol decomposition give birth to take "machinery were / receiving pollution / coalescence were" methanol accept, are respectively assembled, change the traditional mechanical respectively is in respectively after gas methanol content higher than 0. 486% of the defects, after the completion of the gas in the methanol content in the lower than 0. 85% consequences. This technique can be taken every year to cut methanol 2. 14 tons, and the progress of the quality of crude methanol, cover catalyst played a major role. In the process of methanol decomposition, the addition of the film received the assembly, taking over the release of hydrogen gas, and as a re recycling of raw materials, the original design of each year to increase the methanol production capacity of 2. 6 tons. Through process comparison analysis of the coherent case the construction and application of the catalyst, selection of the German chemical company south new catalyst MEGAMAX700. Usage in this decomposition catalyst loading of assembly, restoration, application protection plan, through process trace impurity detection in the catalyst bed hot temperature control and product, on the catalyst and a loading method evaluated analysis, invented the furnace catalyst is now in the transitional stage of the medium-term and in the early, fathom the catalyst service life can arrive 4 years, reaching the expected capacity. 目录: 摘要 3-4 Abstract 4-5 第一章 文献综述 8-20 1.1 探讨背景 8-10 1.1.1 甲醇用途 8-9 1.1.2 甲醇市场供需状况 9-10 1.1.3 建设大甲醇项目必要性 10 1.2 甲醇生产技术近况和发展形势 10-18 1.2.1 典型甲醇生产工艺路线 11-12 1.2.2 国外甲醇合成技术近况 12-15 1.2.3 国内甲醇合成技术近况 15-17 1.2.4 甲醇生产工艺探讨趋势 17-18 1.3 论文选题意义和探讨内容 18-20 1.3.1 论文选题意义 18 1.3.2 探讨内容 18-20 第二章 探讨过程和措施 20-30 2.1 德国鲁奇60万吨甲醇合成工艺装置概况 20-25 2.1.1 德国鲁奇甲醇合成工艺流程简介 20-22 2.1.2 工艺分区 22-23 2.1.3 主要设备 23-25 2.1.4 生产控制系统 25 2.2 探讨措施 25-26 2.3 课题探讨理论基础 26-27 2.3.1 甲醇合成反应原理 26 2.3.2 物料平衡 26-27 2.4 课题探讨所用工器具 27-28 2.4.1 实验用仪表 27-28 2.4.2 调节阀门 28 2.4.3 略论仪器 28 2.5 数据略论 28-30 第三章 结果讨论 30-59 3.1 分离效率提高对甲醇产能的影响 30-34 3.1.1 分离工作原理 31-33 3.1.2 鲁奇60万吨装置分离器运行情况略论 33-34 3.2 膜回收装置对提高甲醇产能的影响 34-37 3.2.1 膜分离工作原理 34-35 3.2.2 膜分离氢气工作流程 35-37 3.2.3 成本核算 37 3.3 甲醇合成催化剂对甲醇产能的作用 37-45 3.3.1 催化剂选用 37-40 3.3.2 催化剂装填情况对甲醇产能的作用 40-41 3.3.3 催化剂还原情况对甲醇产能的作用 41-44 3.3.4 催化剂使用中采用的保护方法 44-45 3.4 优化工艺条件提高甲醇产能 45-59 3.4.1 反应温度对甲醇合成的作用 45-48 3.4.2 反应压力对甲醇合成的作用 48-50 3.4.3 新鲜气成分对甲醇合成作用 50-52 3.4.4 新鲜气中惰性气体含量对甲醇合成的作用 52-54 3.4.5 循环比(空速)对合成反应的作用 54-56 3.4.6 各工艺参数对甲醇合成作用的敏感性略论 56-59 第四章 结论 59-61 4.1 结论 59 4.2 特点与创新 59-60 4.3 展望 60-61 参考文献 61-63 致谢 63 |
