"Daxiangsu" realizes the localization of major petrochemical technology and equipment

Liaoning Daily, March 12, 2019

     Report from our correspondent reporter wang gang reported on March 8, dalian rubber plastic machinery co., LTD. (hereinafter referred to as the "big rubber") successfully produced the first sets of annual output of 350000 tons of polypropylene extrusion granulation unit, not only filled the blank of similar large equipment of petrochemical industry in China, and also broke the foreign technology and market monopoly, accelerate the process of the localization of petrochemical major technical equipment.

'The unit has completely independent intellectual property rights and its technical indicators have reached and equal to the international advanced level,' the sinopec group expert group said in its acceptance report.
Its successful development and production will break the passive situation of China's petrochemical industry relying on import of major technical equipment for a long time.
Polyethylene and polypropylene are the main products of large ethylene projects, which are the basic synthetic resins with the largest demand and widest use.
The large extruder granulator is the key equipment in the large ethylene equipment, and the overall technical level is high.

The technology and market have long been monopolized by three companies from Germany and Japan. In the past 30 years, China's petrochemical enterprises have been relying on imports, which has affected the investment control and construction schedule of Petrochemical engineering projects in China and restricted the rapid development of China's petrochemical industry.
Therefore, the development level of the extrusion granulator reflects the latest achievements and comprehensive strength of a national petrochemical equipment research field from one side.
In order to change this situation, in 2006, Sinopec group decided to form a "national team", including Beijing Yanshan Branch of Sinopec, Sinopec Engineering Construction Co., LTD., Beijing University of Chemical Technology, and Dalian Rubber and plastic Machinery Co., LTD., to jointly tackle key problems.

To undertake major projects of a polypropylene unit localization extruding and granulating machine group in our country since the research task, "big rubber" has completed the annual output of 200000 tons, 250000 tons, 300000 tons and a series of large-scale pelletizing development work, filled a number of domestic blank, broke the monopoly of foreign technology and price, become the only domestic and global one of four large extrusion granulation unit manufacturers.

On this basis, the "big rubber after 19 months to overcome the" machine, electricity, instrument and so on nine big research project, mastered the unit design, manufacture, assembly and debugging and testing technology, complete with independent intellectual property rights the first sets of annual output of 350000 tons of polypropylene device research task of localization extruding and granulating machine group, again to speed up the localization process of petrochemical major technical equipment, highlights the problem of the crack of petrochemical major technical equipment.
