Evaluation of the process, capacity, and performance of methanol plants
Thread Content
Discuss the process, capacity, and performance evaluation of ammonia synthesis plants (including dihydroxyethane, etc.). Please share information on the scale of your methanol plant, its production process, the design company responsible for it, as well as your feedback on that design company after its use. The format is as follows: (1) Production capacity (2) Production process (3) Design unit (4) Evaluation
(1) Production capacity: 100,000 tons of methanol per year. (2) Production process: The steam conversion, low-pressure synthesis, and three-column distillation processes are employed. (3) Design agency: Chengda Design Institute. (4) Evaluation: The project is currently under construction; any findings regarding issues can only be determined after the final inspections and adjustments are completed.
1. Production capacity: 100,000 tons of methanol produced from coke oven gas; 2. Production process: steam reforming; 3. Design agency: Chemical Engineering Institute No. 2; 4. The overall performance is okay, but there are often some minor issues.
(1) Production capacity: 100,000 tons per year of methanol distillation. (2) Production process: Three-tank distillation process. (3) Design unit: Hebei Zhengyuan Design Institute. (4) Evaluation: The operation is fairly good.
(1) Production capacity: 200,000 tons of methanol per year. (2) Production process: It employs a production flow that includes conversion of coke oven gas, low-pressure synthesis at a constant temperature, and triple-column distillation. (3) Design agency: Chemical Engineering Institute No. 2. (4) Evaluation: The overall operation is satisfactory, but there are significant variations in the temperature of the catalyst beds, and the catalyst lifespan is relatively short.
(1) Production capacity: Designed at 30,000 tons; after renovation, it is now 60,000 tons. (2) Production process: Fixed-bed coal gasification, wet desulfurization, decarburization, dry deep desulfurization, low-pressure methanol synthesis, and double-column distillation. (3) Design agency: Fourth Chemical Engineering Institute. (4) Evaluation: Successful commissioning on the first attempt; operation is relatively stable with no major issues
(1) Production capacity: 90,000 tons of methanol per year. (2) Production process: The steam conversion, low-pressure synthesis, and three-column distillation processes are used. (3) Design firm: Tianyi Design. (4) Evaluation: The first commissioning was successful without any major problems; there were only minor design flaws, which we corrected through our own technical improvements
(1) Production capacity: 50,000 tons of methanol per year. (2) Production process: The steam conversion, low-pressure synthesis, and three-column distillation processes are used. (3) Design agency: Chemical Engineering Institute No. 2. (4) Evaluation: There are some minor issues, but they have all been resolved through long-term operation
(1) Production capacity: 100,000 tons per year of methanol distillation. (2) Production process: Three-tank distillation process. (3) Design agency: Chemical Engineering Institute No. 2. (4) Evaluation: The operation is fairly good
(1) Production capacity: 100,000 tons of methanol per year. (2) Production process: low-pressure synthesis and three-column distillation process. (3) Design firm: Hunan Anchun High-Tech Co., Ltd. (4) Evaluation: The project is currently under construction; any issues will be addressed after the plant starts operating successfully.
