On the 18th, Jilin Petrochemical's annual 300,000 tons sulfur-containing wastewater acid plant successfully launched. This device is a key cleaner production demonstration project in Jilin Province. It introduces advanced MECS technology patents and uses sulphur-containing wastewater generated from acrylonitrile and methyl methyl ester plants as raw materials. After processing, it can produce different concentrations of sulphuric acid. The acrylonitrile and methyl ester units are recycled as raw materials.
It is understood that in the past, sulfur-containing solutions of by-products from acrylonitrile plants were sent to supporting facilities for recycling for the production of ammonium sulfate. However, due to the excess domestic ammonium sulfate market and poor product sales, the production capacity of ammonium sulfate plants is not sufficient to digest all sulfur-containing solutions. It costs RMB 40 per ton for external processing, and the methyl ester production process The waste acid water also needs to be treated the same, and these two items cost more than 20 million yuan each year.
The successful implementation of 300,000 tons of sulfur-containing wastewater acid production not only achieves clean production, but also opens up a way for the company to develop a recycling economy. Not only the wastewater recovery problem is solved, but also the concentrated sulfuric acid produced can be used as a raw material for production, with a typical recycling economy. Features.

This generation of biomass fuel pellet mill with big gearbox, with advantage as follow:
1-all gears flat connecting no taper gears, structure more properly than before,
2-and gears more bigger and tronger than before, roughly no need change the gears ,
3-the motor shaft and the machine main shaft directly connecting into the gearbox, so machine transmission efficiency is more higher than before.
