Welding manipulator also called as Welding column boom, which always combine with Welding Rotator and Welding Positioner to become the dedicated automatic welding device for welding structure parts` internal and external circular seam, fillet weld, inside and outside longitudinal seam and has different structure forms such as fixed type, rotary type, versatile position type, etc.And according to user`s requirements, we also can choose structure or equipped with different kinds of welding machines and adding tracking, swing, monitoring, solder recycling& conveying functions. The welding manipulator is widely used for many kinds of industries such as pressure vessel, cooling device, power plant construction, metallurgical construction, engineering machinery, shipbuilding, roll surfacing welding, petrochemical construction, etc. Welding Manipulator,Tank Welding Manipulator,Automatic Robot Welding Manipulator,Boom Welding Manipulator Zhengzhou Yueda Technology Equipment Co., Ltd. , https://www.yuedawelding.com
Acetone and butanol are two very important chemical raw materials and solvents in industrial processes. With the development of downstream industries in recent years, the market demand for acetone and butanol has risen. It is understood that the annual consumption of acetone and butanol in China exceeds 500,000 tons, but the production capacity is less than 400,000 tons, and large amounts of acetone and butanol are required to be imported each year.
Fermentation process to produce acetone butanol is low cost
The reporter recently learned from Beijing University of Chemical Technology that the process of producing acetone and butanol using the corn fermentation method developed by the university has a butanol yield of 70%, a starch conversion rate of 25%, and a fermentation process of only 36 hours. The process is short. The raw material utilization rate is high. The process has maintained a “zero†rate for four consecutive years in pilot production at the North China Pharmaceutical Factory's 107 workshop, setting a record for the best in the industry in the country, significantly reducing production costs.
