Luoyang Petrochemical saved more than 20 million yuan in auxiliary material costs in the first 9 months

According to China Petrochemical News Net, Luoyang Petrochemical strictly manages auxiliary materials, combined with the actual production and operation of the device, and on the basis of in-depth analysis of the completion of the three-agent auxiliary material indicators, further reduces and decomposes the three-agent indicators, and refines them to the device to "quote management".
"Total control, grading responsibility" is the main line, and the refined management of auxiliary materials is strengthened.
From January to September, the oil refining sector saved 8.
97 million yuan in auxiliary materials, and the chemical sector saved 11.
87 million yuan in auxiliary materials
.

In combination with the actual situation of the catalytic device, the company implemented the “stop if you can stop, and reduce if you can reduce” the agent used in the device.
It stopped two sets of metal passivators for the catalytic device.
Contact with the Chinese Academy of Sciences and adjust the catalyst formula of the two sets of catalytic devices in time when the feed properties change to reduce the unit consumption of catalyst and the selectivity of coke production; add low magnetic agent to the two sets of catalytic devices according to a certain proportion, instead of fresh It can reduce the unit consumption of catalyst and create conditions for the reuse of low magnetic agent
.

At the same time, the company has made research on the catalyst unit consumption of the 2# reformer, such as the use of PSA product hydrogen regulating valve to stably increase the hydrogen source pressure; according to the proportion of catalyst dust particles, the elutriation air volume will be reduced from 2800 cubic meters per hour to Measures such as 2740 cubic meters per hour have allowed the amount of catalyst dust to be controlled
.

The company also controls the temperature increase rate of the reaction part of the diesel and residual oil hydrogenation unit to slow down the catalyst deactivation rate; determines the catalyst grading plan for the next cycle of diesel hydrogenation; optimizes the calcium carbonate, The proportion of calcium oxide dosage can reduce the cost of auxiliary materials; monitor the operation of the heat exchanger of the upstream device, and switch in time if there is a problem, reduce the cost of the circulating water system chemical, and finely control the pH of the biochemical system in the sewage treatment area, and run intermittently Add alkali facilities to reduce the consumption of alkali
.

In addition to optimizing the production operations of the refining sector and strictly controlling the cost of auxiliary materials, the company also pays attention to the management of the "three agents" in the chemical sector
.

　　At the same time, use the 1# polypropylene device to add a new propylene refining tank to increase the dehydration capacity, improve the quality of propylene, and reduce the consumption of triethyl aluminum; optimize the production operation of the 2# polypropylene device, and regularly perform the refining section of the molecular sieve tower T700A/B/C, T703B performs hot nitrogen regeneration to reduce the influence of the water content in propylene on the main catalyst, thereby reducing the consumption of the main catalyst; fully use the 0.
14 mm thick FFS heavy film, continue to optimize the operation of the packaging line, and reduce the loss of bags and materials during the packaging process.
The frequency of occurrence of the situation reduces the waste and waste of packaging materials
.

　　In addition, the company has also strengthened the monitoring of the unit consumption of main agents, timely analyzed the reasons for the unit consumption of catalysts exceeding the index, and strictly assessed the units whose unit consumption exceeded 5% of the index
