On May 26, Chongqing Huafeng's 300,000-ton/year adiponitrile project (Phase III) successfully completed the mechanical completion and entered the stage of full commissioning and start-up
.
It is reported that the project (Phase III) is planned to be officially put into operation in June this year.
By then, Chongqing Huafeng will have an annual production capacity of 200,000 tons of adiponitrile and 200,000 tons of hexamethylene diamine, which will further ease the domestic adiponitrile/hexane production capacity.
The contradiction between supply and demand of diamine is of great significance to the large-scale and high-quality development of the domestic nylon 66 industry
.
The "300,000 tons/year adiponitrile project" is after Huafon Group broke through the adiponitrile "stuck neck" technology, based on the current situation of the adiponitrile/hexamethylene diamine and nylon 66 industry at home and abroad, relying on the industrial supporting facilities of Baitao Industrial Park Advantages, it is a key project for investment and construction in Chongqing
.
The third phase of the project is designed and constructed on the basis of the construction and operation experience of the previous two phases of the project.
The construction content includes 100,000 tons/year of adiponitrile and 100,000 tons/year of hexamethylene diamine and other main units and their supporting facilities.
.
It is understood that Chongqing Huafon has built two sets of 50,000 tons/year adiponitrile production plants using the adipic acid method to produce adiponitrile.
At present, the two sets of plants are running stably, and the unit energy consumption is better than the design target value.
The quality is at the leading level in the industry, which solves the problem of "presence or absence" of domestic self-produced adiponitrile, and breaks the passive situation of high price that has been monopolized by domestic adiponitrile for many years
.
