Jiujiang Petrochemical's detailed measures optimize the whole process and strengthen management to save energy and reduce consumption

On April 5, Jiujiang Petrochemical's production and operation dispatching meeting announced that the monthly crude oil processing tasks and product allocation plans have been fully completed in the first quarter, and the production of gasoline, liquefied gas and xylene have all reached historical highs
.
At the beginning of this year, Jiujiang Petrochemical, combined with the annual tasks of the headquarters, sorted out the three main tasks of "low load operation, heavy load operation, and national 5 operation period".
Through scientific calculations, it was determined to increase the yield of light oil and increase the production of gasoline and diesel.
, More than 80 optimization measures such as producing more aromatics, increasing the yield of liquefied petroleum gas and propylene
.
Practical measures are needed for stable operation.
On January 11, the general manager of the company awarded medals, certificates and bonuses to employees who found hidden dangers and avoided accidents and awarded second-class merits.
Second-class merits of employees are rare in Jiujiang Petrochemical
.
Since the beginning of this year, Jiujiang Petrochemical has combined the requirements of the group company’s safety work video conference to focus on the deployment of safety production work.
The company’s cadres and employees have carried forward a strict and practical >
.
At the same time, the company revised the relevant management rules, and for the first time put forward the requirement of “full-process video surveillance for major and high-risk operations”, emphasizing job safety accountability and ensuring the company's safe production work in an orderly manner
.
In the first quarter, the company withstood the severe test of the extremely cold winter weather.
All production units thoroughly searched for and dealt with installations and hidden safety hazards, and arranged safety, production, fire control, comprehensive management and stability maintenance work in an all-round way, laying a solid foundation for the steady growth of economic benefits Foundation
.
Good news came on February 23 that the coal-to-hydrogenation unit A boiler operated safely and steadily for 102 days, setting the best performance of Sinopec's similar technical equipment in operation cycle
.
Safe production is the prerequisite and basis for improving quality and efficiency
.
In the first quarter, the company processed 1,586,100 tons of crude oil, and the overall commodity rate, light oil yield, and high-value product yield increased significantly
.
At the beginning of the year, the company set up a whole-process optimization team innovation studio, led by improving product value increments, refined the whole-process optimization measures, deeply promoted the overall optimization, and promoted the company to improve quality and efficiency.
Fully implemented
.
While stabilizing production and operation, the company focused on the optimization of the whole process and distillate processing route, the optimization of the operation of the two sets of catalytic devices to increase the production of gasoline and liquefied gas, and the optimization of the operation of continuous reforming to increase the octane number of reformed gasoline, etc.
, Boosting the company's marginal benefit of processing tons of oil
.
On March 16, the company fully launched the "improvement of the new centralized management and control model" to further strengthen the system and mechanism of the "three basics" work and optimize coordination capabilities to provide strong support for the company to improve quality and efficiency
.
Increasing gasoline production is an important growth point for corporate profits
.
In February, at the peak of the passenger flow during the Spring Festival, the domestic market was in short supply of No.
97 gasoline
.
The company seized the opportunity and did not relax, optimized production and operation, and further tapped the potential of the catalytic device.
The catalytic gasoline yield averaged more than 53%, maintaining a relatively good level among similar devices.
The 97th gasoline production and sales volume set a record high in the month
.
After analyzing and judging the increase in the price of vehicle diesel and the market situation, the company organized the optimization and adjustment of increased production of vehicle diesel.
In March, the output of vehicle diesel reached 231,900 tons
.
At the same time, the company closely followed the pace of the market and optimized the production of high-value products such as liquefied gas and xylene.
In the first quarter, the production of liquefied gas and xylene increased by 44.
46% and 509.
33%, respectively, setting record highs
.
Strengthen management to save energy and reduce consumption.
In 2016, after the 8 million-ton/year project was completed and put into production, the company's energy-saving work shifted its focus to energy-saving process and equipment management.
Whenever there is a point of benefit, it will try its best to extract it
.
Focusing on energy conservation such as steam, electricity, and water conservation, the company has carried out in-depth special treatment of energy conservation in the process, compared with the operating conditions of each device, sorted out 123 energy-saving optimization measures such as steam and electricity, and adopted reasonable arrangements2 The operation mode of 1 CFB boiler and 2 oil-fired boilers increases the self-produced steam volume of process equipment and increases the proportion of waste heat recovery; carries out optimization measures such as improving the thermal efficiency of heating furnaces, reducing steam consumption, strengthening heat supply and heat joint management between equipment, and strictly Control consumption
.
At present, all 123 energy-saving measures have been put in place, which can save 30.
5 tons/hour of steam, 3560 kWh/hour of electricity, 1.
35 tons/hour of fuel, 1920 tons/hour of circulating water, 29.
5 tons/hour of demineralized water, and fresh water.
48 tons/hour
.
With regard to the adoption of new technologies, the hydrocracking unit and the residual oil hydrogenation unit newly added hydraulic turbine equipment, which is expected to save 8 million kilowatt-hours of electricity annually and reduce costs and increase efficiency by more than 4.
8 million yuan per year
