With the continuous development of downstream products of methanol and promote the use of methanol fuel, methanol and ammonia generation of more and more enterprises are becoming ever larger, higher and higher alcohol than ammonia. However, the ensuing problem is circulating volume increases, the resistance of the tower is also growing. Therefore, the resistance to methanol synthesis tower bound together into methanol production capacity of ethanol plants, a critical issue, the synthesis is to determine the resistance of the tower pieces the size of the key components. How to develop an energy-efficient, low-resistance tower parts of methanol,
CAS 3391-83-1, methanol production is currently very much looking forward to the technology industry.
The use of various forms of domestic methanol production Internals widespread resistance, high power consumption and the problem of low catalyst utilization factor. Shijiazhuang Zheng Yuan Tower Equipment Co., Ltd. After several research trials, according to Shijiazhuang Ji Yuan Chemical Co., Ltd. Lee is the old reactor outer tube conditions, has produced a DR-type self-designed pieces of methanol and developed a supporting tower pre-boiler Methanol synthesis system process, and effectively solve this problem. It is understood that the inner parts of the new resistance, low power consumption, high utilization coefficient of the catalyst, catalyst basket for a double structure, that is, a tower can be used for two towers, one tower to a substantial increase in production capacity, the catalyst also has a dump function, make operation more convenient. The technology is suitable for small nitrogenous fertilizer and methanol production enterprises in technological innovation and new projects, but also to the low capacity ammonia out of the tower renovation, the methanol synthesis reactor.
In particular, DR-based methanol internals structural features are as follows: First, the double layer structure composed of one into a can filled from a synthesis of all the catalyst for the upper tower, filled with convenient and no gaps. Replacement of catalyst, catalyst unloading open the bottom of the blind hole, pouring the catalyst can do, not hanging out in pieces, reducing the time to replace the catalyst, to improve work efficiency, reducing the effective loss of production time. Second, the two catalyst synthesis reactor gas fabric devices are using the new distribution technology, gas to enter, mix evenly into the catalyst layer, the bed temperature stability, a reasonable distribution, and extended trim life. Third, the gas streaming, layered thermostat. As a result of double-tower structure,
fine chemicals, while the gas into the twin towers into the catalyst, the whole tower resistance, the initial resistance of only 0.02 MPa, generally less than 0.10 MPa, fully embodies the characteristics of low resistance; the same time, adjust the operating means of a flexible, adjustable bed temperature can be layered, so that the activity of the catalyst in a better temperature, catalytic efficiency. Fourth, reduce the heating power consumption, improve the efficiency of electric heaters. As a result of entering and exiting process, its unique twin structure only can be achieved using a catalyst Taipower heater TPR and non-heating under normal conditions.
Currently, low resistance, energy-DR has been used in methanol Internals yuan Shijiazhuang in Hebei Chemical Co., Ltd. is high-pressure Methanol, Longgang Chemical Co., Ltd. in Hebei Qiuxian pressure Methanol, Fertilizer Co., Ltd. Shijiazhuang Zhengyuan Methanol medium pressure device, using the results very satisfactory. The result shows that the inner parts, low resistance, high catalyst utilization factor, easy to operate, and can recover low pressure steam to the energy, the effect of reducing operating costs. The use of the display, 800 mm diameter, 14 meters high tower high-pressure methanol (Methanol) resistance of only 0.1 to 0.12 MPa for the tower with a high degree of resistance of 1 / 8, and methanol production can be increased to 160% of the original,
Musk R-1, circular electrical energy consumption by 30 percent. Large domestic fertilizer production enterprises - Hubei Yihua Group is also its 50,000 tons / year methanol technical transformation project, with a diameter of 1,400 mm DR methanol tower pieces. Source: www.mhcfm.com
