Maoming Petrochemical's "three-pronged approach" strives to maximize the benefits of stock assets

China Petrochemical News Network News Since this year, Maoming Petrochemical's refining division and the fifth workshop have focused on key points and difficulties in creating efficiency, continued to deepen lean management, and strived to optimize operations to increase the output of high-value products, save energy and reduce carbon, and reduce costs and expenses
.

From January to June, on the basis of the successful completion of the overhaul of the No.

Optimize the output of high-profit products with increased production prices

"Elaborate operation, stable operation, improve indicators, and make every effort to increase the output of high-priced and high-profit products
.

" At the beginning of the year, the workshop put forward clear requirements to all employees

No.
2 and No.
4 catalytic devices are the main benefit devices, whose main task is to increase the production of gasoline and liquefied gas
.

Since February, facing the two sets of catalytic devices gradually adjusting the reaction depth, the amount of rich gas generated by the reaction has increased, and the air pressure has been overloaded, resulting in the technical bottleneck of the device's low operating load.

The workshop uses information software to calculate the optimized operation of multiple simulation devices, and through the implementation of optimization adjustments, the temperature of the rich gas at the inlet of the compressor is significantly reduced.
Under the same operating conditions, the rich gas at the inlet of the compressor is reduced by 1500 standard/hour
.

Since March, the processing capacity of No.

From January to June, the liquefied gas yields of No.
2 and No.
4 catalytic units increased by 0.
24 and 0.
44 percentage points respectively compared with the same period of last year.
The cumulative production of gasoline was 455,200 tons, an increase of 71,600 tons compared with the same period last year
.

　　Overcome difficulties and eliminate the "blockers"

　　The workshop pays close attention to the key points and difficulties of equipment creation, and taps into the potential of creating benefits.
While increasing the application of new technologies, the workshop carries out special research to eliminate the bottleneck of efficiency creation and eliminate the benefit "blockers"
.

　　Since the overhaul of No.
2 catalytic device started in mid-January, the product distribution has not reached the ideal requirements.
In order to further improve the product distribution of the device, increase the cracking capacity of the device, and maximize the output-to-input ratio and cost-effectiveness, the workshop actively promotes the application of new additives

　　Reducing the large octane loss of the two SZorb devices is another difficulty for the workshop to create efficiency
.

The workshop has continuously strengthened communication and coordination with branch technical quality rooms, quality inspection units and other units, in-depth analysis of the root causes of Szorb octane number loss, while strengthening basic management and process management, it does a good job of tracking the catalyst data process, and repeatedly carries out crawling.

　　Carefully adjust and practice energy saving and carbon reduction

　　The workshop pays attention to improving the energy-saving awareness of all employees, analyzes and compares the energy consumption of the same advanced domestic equipment with the best level of the equipment in the same period, finds gaps, and formulates catch-up measures
.

Pay close attention to the energy waste of water, electricity, wind, steam, etc.

　　At the end of April, the workshop conducted an investigation on the frequency conversion operation of 36 air-cooled units of No.
4 catalytic gas separation unit, and compared and calculated with thermoelectric professionals.
It was concluded that the power consumption of one air-cooled unit with a 100% load was equivalent to 8 units with a 30% load.
Air cooling power consumption
.

The workshop has formulated and implemented more than 10 energy-saving measures such as multi-opening frequency conversion air cooling and maintaining frequency conversion low-load operation

　　Recently, as the temperature rises, the workshop has carefully adjusted the circulating water consumption of the dry gas enrichment and the two sets of SZorb device water coolers, and appropriately reduced the circulating water consumption of the dry gas enrichment unit 100, 300 unit and the No.
2 SZorb device respectively.
A total of about 1072 cubic meters per hour of circulating water can be saved, and monthly electricity consumption can be saved by 230,000 yuan
.

　　Since the second quarter, the workshop has received more than 120 suggestions for energy-saving optimization operations from employees.
The energy consumption of No.
2, No.
4 and dry gas enrichment devices has decreased significantly compared with the same period last year.
The waste heat power generation of the No.
2 catalytic device unit has increased by 356,200 year-on-year.
Kilowatt hours
