Different from the previous performance tests, this high-load performance test was carried out after the PTA three devices were replaced by parking.
Through testing, the overall performance of the device has been improved, laying a good foundation for this performance test. Yangzi Petrochemical Chemical Plant also seized the opportunity to conduct high-load performance testing on the eve of the “May 1st†holiday. In view of the bottleneck problems in the past tests, the PTA three devices have been consciously adjusted and optimized in the test operation. For example, the technical reform measures are used to fully recycle all kinds of steam; the circulating water consumption is further adjusted. Reduce the inefficient water consumption; also accurately calculate the various data meters, and strive to truly reflect the actual consumption level of the device.
After scientific statistics, the four major indicators of product quality, raw and auxiliary materials consumption, environmental protection and energy consumption of PTA three devices have improved significantly compared with the previous test results. Among them, the comprehensive energy consumption index is much better than the previous test results, lower than The design guarantee value provided by the patent company has basically reached the advanced energy consumption level in the same industry in China.
It is understood that the PTA three devices will use this high-load test result as the basis for the long-term high-load operation of the device, continue to maintain the successful operation methods and results in the test, and strive to find the optimal operation point for the long-term high-load operation of the new device. In addition, the device will also perform 110% design maximum load test, which will provide a basis for future deepening of the device.
Breakthrough in high load test of PTA three devices
Recently, the PTA three devices of Yangzi Petrochemical Chemical Plant have received good news. The overall test index has been the best level since the start of the car in the 100-hour high-performance 72-hour performance test.
