Sinopec Shanghai Engineering Co., Ltd., Shanghai Jinshende Powder Engineering Co., Ltd. and Yangzi Petrochemical Co., Ltd. jointly carried out a large-scale PTA (pure terephthalic acid) long-distance transmission engineering research and development project recently organized by Sinopec Joint Stock Company. The results of identification.
PTA, which is the main raw material for the chemical fiber industry, uses the air flow after it is produced in the form of powder, especially for long-distance transportation, which has become a technological bottleneck for new installations and transformation of enterprises. In order to solve this problem, in 2003, the Ministry of Science and Technology of Sinopec Corp. hired experienced German experts to provide technical guidance. Designed by Shanghai Engineering Co., Shanghai Jinshende Powder Engineering Co., Ltd. undertook the construction of a large-scale pneumatic conveying test device for powder pellets. The test device has a high degree of integration and flexibility, and its technical level, function and scale are among the highest in the world. In the 2004 Shanghai Petrochemical PTA plant gas transmission reconstruction project, the transformation project using this technology was successfully put into production. Compared with the tender prices of foreign companies, the investment was saved by nearly 1/4.
In 2006, in the 450,000 tonne/year PTA expansion project of Yangzi Petrochemical, the distance from the PTA plant to the new packaging plant was 1,100 meters. In order to solve the problem of long-distance airflow PTA transmission, all parties involved in this technology research and development worked together to demonstrate and improve the entire PTA long-distance transmission program. After eight months of unremitting efforts, the project was completed in November 2006. Put into operation, so far production is stable.
