The new-generation patented technology product developed by Hangzhou Linda Chemical Engineering Technology Co., Ltd. has been successfully put into operation in Inner Mongolia Sulige Natural Gas Chemical Industry Co., Ltd. The results of the operation show that since June 16th, the production of refined alcohol has reached 624 tons/day at full capacity, exceeding the design value of 600 tons/day.
The device is the world's first large-scale horizontal water-cooled methanol synthesis reactor industrial device with an inner diameter of 3.4 meters and a weight of 180 tons. It is independently developed by Linda and is used for 180,000 tons of methanol annually for the first time this year in Inner Mongolia Sutianhua. Technical renovation project to replace the original imported Mitsubishi cold-excursion methanol tower. The device was heated and reduced at the beginning of June. After a short time light-load test run, it has reached full-load production and the operation is ideal. The temperature difference during operation is small, and the temperature is even and steady, which changes the conditions of high temperature difference before the transformation, large temperature fluctuation of the bed, and unstable operation. In the process of reduction and commissioning, the horizontal water cooling tower has convenient temperature adjustment, good operation and control performance, and a significant drop in the temperature difference between the beds.
Due to many limitations of the traditional synthesis reaction, Linda's horizontal water-cooled methanol tower showed many advantages after it was put into operation: the resistance of the synthesis tower bed was very low, and the pressure difference between the inlet and outlet towers was only 0.02-0.03 MPa. One-tenth of the synthesis tower; the high pressure difference between the inner and outer diameters of the heat exchange tubes has exceeded 7MPa, and the pressure differential that can withstand up to 9MPa according to the design is rare for the current domestic and foreign water-cooled synthesis reactors. The design of high pressure difference is to reduce the size of the synthesis tower. , improving production capacity provides the conditions; low cycle ratio, high net methanol value. The horizontal water cooling tower has a design cycle ratio of 2.5. Currently, it is only about 2.1, which is 50% lower than usual. According to the actual methanol production accounting, the net alcohol value can be as high as 9%, which is 2 times that of the general synthesis tower; the heat exchange area can be designed according to the heat release size of the reaction process, and there is a strong heat transfer capability. Low cycle ratios provide conditions for large scale. The capacity of a single horizontal water cooling tower can reach more than 1 million tons, and the contracted annual production capacity of 600,000 tons and 1 million tons of methanol towers are single-tower solutions.
It is reported that Linda has developed a one-step method for producing dimethyl ether, a one-step synthesis gas to produce methanol from gasoline, and a syngas supply system to develop gasoline and other reactors and processes on the basis of a horizontal water cooling tower.
