In order to reduce the dust discharge of the polypropylene plant by 200,000 tons/year, the Yan'an Petrochemical Plant implemented a number of measures
this year.
Up to now, its dust discharge volume has been reduced from an average of 20 bags / day to 5 bags / day, and the powder is reprocessed into polypropylene products, turning "coarse grain" into "fine grain"
.
As the largest polypropylene plant in Shaanxi, the plant has been able to meet the design values
in terms of production capacity, product quality and performance since the start of construction in June 2009.
However, in the production process, after the polypropylene device is washed through T-502, a large amount of dust entrained in the circulating nitrogen is removed, which not only causes a great waste of raw materials, but also has a certain impact
on the yield of polypropylene.
