Since the beginning of this year, the PTA (purified terephthalic acid) unit of Yangzi Petrochemical Plant has taken the opportunity of "green enterprise creation" to vigorously carry out energy conservation and emission reduction work, through optimization and transformation, implementation of new processes, and daily refined management and other measures , the green production has achieved remarkable results
.
"The reduction of single discharge of sewage involves all aspects, but the key point this year is that the second and third lines of PTA have implemented a balanced transformation, which has an obvious effect
.
After long-term optimization and transformation of PTA Line 3, the demand for circulating solvent has been continuously reduced, and the current designed water supply per hour is nearly 20 tons more than the actual consumption
.
It needs to be discharged on the one hand, and water needs to be replenished on the other hand.
If they use each other, wouldn’t it be a great improvement
.
"In addition to the obvious results in reducing emissions, we have also made great efforts in the reuse of sewage
.
The key personnel will keep an eye on the scene, sort out and investigate the possible root causes one by one, and based on the statistics of the indicators, formulate directions and formulate optimization measures after discussion and analysis
.
They took precautions and mobilized all staff to make suggestions, and adopted the "golden idea" of "reusing and transforming the washing water of the bed in the water-dissolving position" proposed by the staff
.
In addition, according to the temperature change, the factory made process adjustments in advance, and continued to carry out water inspections for industrial water and domestic water, so as to find leaks and deal with them in time to prevent the phenomenon of long-running water on site
.
