甲醇转化工段投氧操作法
摘要：
本发明涉及一种甲醇转化工段投氧操作法，属于甲醇合成技术领域。该操作法包括以下具体工作过程和步骤：（1）预热焦炉气；（2）供燃料气；（3）供氧气；（4）锅炉给水；（5）处理冷凝液；（6）处理转化气。该甲醇转化工段投氧操作法用0.6MPa低压蒸汽代替3.0MPa中压蒸汽进行转化工段的投氧，此操作法运行良好，在每次开车时节约了大量的时间，有效地提高了生产的运行周期。同时也为电厂和其它部门节约大量的中压蒸汽，为稳定生产提高了效率，节约了大量开车资金，降低了生产成本。
摘要（英）：

The invention relates to an oxygen feeding operation method at a methanol conversion section, belonging to the technical field of methanol synthesis. The operation method comprises the following working processes and steps: (1) preheating coke oven gas; (2) supplying fuel gas; (3) supplying oxygen; (4) supplying a boiler with water; (5) treating condensate; and (6) treating conversion gas. According to the oxygen feeding operation method at the methanol conversion section, the oxygen feeding of the conversion section can be conducted through 0.6MPa low-pressure steam instead of 3.0 MPa medium-pressure steam, the operation method is favorable in implementation, a great amount of time can be saved in each driving, and the running period of the production can be effectively improved. In addition, a great amount of medium-pressure stream can be saved for a power plant and other departments, the efficiency of stable production can be improved, a great amount of driving investment can be saved, and the production cost can be lowered.
