In the synthesis reaction of the methanol column, the resistance is one of the key factors affecting the methanol production and energy consumption, and the internals of the synthesis column are the key components that play a decisive role. Shijiazhuang Zhengyuan independently developed new types of internal components with low resistance, low power consumption and high catalyst utilization factor. Due to the double-layer catalyst basket structure, one tower can be used for two towers, so that the single tower production capacity can be greatly increased, and the catalyst can also be dumped. The function makes the operation more convenient. This product is suitable for small and medium-sized nitrogenous fertilizer companies and methanol production companies to carry out technological transformation and new projects, but also for the transformation of low-yield synthetic ammonia towers that are phased out into methanol synthesis towers.
Up to now, there are a number of chemical fertilizers in Hebei Province that have used the internals. The results show that the internal resistance is low, the catalyst utilization factor is high, the operation is convenient, and the low-pressure steam can be recovered, achieving the effect of energy saving and reducing the operating cost. The use of high-pressure methanol towers (alkanol) with a diameter of 800 mm and a height of 14 meters is only 0.1 to 0.12 MPa, which is 1/8 of the resistance of the same tower, and the methanol production can be increased to 160% of the original. Reduced consumption by more than 30%. The domestic large-scale fertilizer manufacturer, Hubei Yihua Group, applied this time a DR-type double-layer methanol synthesis tower internals with a diameter of 1,400 mm for its 50,000-ton methanol reform project.
At present, the cold-tube type internal parts mainly used in methanol production facilities in China have the problems of high resistance, short service life, easy aging of catalysts, and low utilization rate. In order to prolong the life cycle of the catalyst, many companies use the method of increasing the amount of catalyst loading, increase the spare coefficient, increase the investment cost of the catalyst, and increase the running resistance, which increases the power consumption of the device.
In order to solve this problem, Shijiazhuang Zhengyuan Tower Equipment Co., Ltd. successfully developed DR-type low-resistance double-layer methanol synthesis tower internals last year and obtained national patents. Zhengyuan Group then applied the product to its chemical fertilizer plant, and achieved significant energy-saving and efficiency-enhancing effects. Subsequently, it was successively promoted and applied in several enterprises in Hebei Province. At present, this product is being paid more and more attention by enterprises. Many domestic companies have signed contracts with Zhengyuan and entered the design and implementation stage.
Double-layer methanol synthesizer internal parts increase production and reduce consumption
Yesterday from Shijiazhuang Zhengyuan Tower Equipment Co., Ltd., the company successfully developed the DR-type low-resistance double-deck methanol synthesis tower internals, which are currently being installed and commissioned by Hubei Yihua Group and will be put into operation within two to three days. This original new methanol synthesis tower internals not only can significantly increase methanol production, but also have outstanding energy-saving and consumption-reducing effects. It will save energy and increase efficiency for synthetic ammonia-linked alcohol companies and methanol production companies.
