Replies are rewarded – discussions are welcome. -------------------------------------------As of November 5, the world’s first large-scale 64-square-meter concentration filter has been in operation for over a month in the 50,000-ton/year 1,4-butanediol (BDO) production facility of Hebi Coal Chemical Co., Ltd., which is part of Henan Energy and Chemical Group. Operational data show that the production rate of the 1,4-butynediol (BYD) clear liquid remains stable at 7 cubic meters per hour; the extracted liquid is clear and transparent, the flow rate and pressure difference meet the design values, and all operational parameters of the equipment are normal. The 64-square-meter concentration filter used in this device is provided by Western Bode Technology Co., Ltd. With the existing equipment configuration, this filtration unit can increase the original production capacity of the single-line BDO plant from 20,000 tons per year to 25,000 tons per year. Under conditions of an internal pressure of 0.35 MPa and a feed circulation flow rate of 23 cubic meters per hour, the output volume of BYD clear liquid can reach 7 cubic meters per hour, resulting in a **improved extraction efficiency**.
Hebei Hebi Coal Chemical uses formaldehyde and acetylene produced by upstream facilities as raw materials; under the action of catalysts, these substances are reacted to produce BYD, which is then hydrogenated to yield BDO. The concentration filter is an important product device in BYD’s extraction process, determining BYD’s extraction volume and the daily production capacity of BDO. Currently, the filtration area of the concentration filters used in the BDO industry is 50 square meters each, which limits the extraction capacity of a single unit and hinders an increase in the plant’s production capacity. To this end, Western BaoDe established a dedicated task force to focus on research and development in areas such as the pore structure of filter media, filtration permeation flux, mechanical strength of structural components, torque distribution of the main shaft, combined axial displacement, deformation simulation at high speeds, slurry flow field distribution, and wear-resistant sealing systems. The research team spent 30 months developing a filter with an area of 64 square meters, which was installed, tested, and put into use on October 1, 2022, at the coal chemical plant in Hebi, Henan. Currently, this device has been operating successfully at Henan Hebi Coal Chemical Industry for over a month. Since its deployment, the 64-square-meter concentration filter has brought significant improvements in terms of extraction efficiency, resistance to clogging, and operational monitoring. In October, the BDO production at the coal chemical plant in Hebi, Henan, reached 11,300 tons, with an average daily output of 378.93 tons. In terms of anti-clogging performance, the 64-square-meter concentration filter breaks away from the traditional feeding method by introducing upper feeding for the concentration filter, which helps prevent blockages in the feeding distribution pipes and deformation of the filter plates.

Thanks for sharing. I would like to ask what the differences are between a concentration filter and a regular filter. Excuse me.
Wish a prosperous and strong China.
