"Only by fine-tuning and running diligently, can the production be more secure in ice and snow weather".
Hunan Petrochemical Refining Department II often urged the area to see.

On the evening of February 23 (Friday), northern Hunan was covered with ice and snow, and the temperature dropped to nearly minus 5 degrees Celsius. At about 22 o'clock, Zhou Guoqiang, the squad leader of the normal pressure catalytic (atmospheric pressure catalysis) area of the second refining department of Hunan Petrochemical, and his apprentice Chen Liang grabbed the vertical ladder full of ice and climbed the platform more than 20 meters high again to adjust the production operation.
In the past few days, affected by the continuous low temperature, freezing rain and snow weather, the operation indicators of the thermal balance equipment of Hunan Petrochemical No. 3 catalytic unit need to be followed up and adjusted in time to ensure the overall safe and stable operation. With an annual processing capacity of 2.8 million tons, the No. 3 catalytic unit is one of the main units for the production of refined oil, heavy oil and liquefied gas.
The thermal balancing equipment is on the high-rise vertical platform, and due to the change in processing capacity and related operating data, a valve that usually does not move much, has to climb up for fine-tuning almost every hour when everyone is on duty recently. Zhou Guoqiang said.
Zhou Guoqiang is a model worker in Hunan Province, who has been on the job for 36 years and has practiced "all-round" operation skills. First, he arranged the work tasks and told the precautions, "The freezing at night is especially bad, and we will find a way to solve the problem together." ”
Climb up to the high-rise platform, and the biting cold wind blows in your face. Zhou Guoqiang held the flowie-talkie and the internal operation docking medium adjustment data in his left hand, and gently pulled the valve with a wrench with his right hand, and reminded Chen Liang of the essentials of operation from time to time. "Although this is a job where practice makes perfect, there are still many details to pay attention to.
The large processing capacity of the device, and the change of product yield by 1 unit, will affect the output and quality of hundreds or thousands of tons of gasoline, diesel and liquefied gas. Zhou Guoqiang said that there are many production data, and if one of the data is not optimized and adjusted in time, there may be a "domino effect".
Recently, the technical team of the second refining department has been squatting at the site, exploring the operating conditions of the device under the conditions of ice and snow and low temperature climate, and guiding the team to optimize and adjust various operating indicators. The personnel on duty go to the site every hour to check the operation of the process and equipment, form a grid control mode with the production team, and investigate and rectify all kinds of hidden dangers in a timely manner.
It is not easy for the device to be stable and open well in the ice and snow, the production load is high. Zhou Guoqiang said, "Sometimes when I just start eating, I have to put down my chopsticks and quickly go to the scene to adjust the valve." "Only by fine-tuning and running diligently, can the production be more secure in ice and snow weather".”
The front process of the device is stable, the dry point of crude gasoline must be controlled, and the product quality control of the follow-up post can be easily controlled. Coming down from the high-rise platform, Zhou Guoqiang took off his work gloves, rubbed his frozen hands, returned to the operation room, and communicated with the internal operation while staring at the changes in the operating data on the monitor.
It is understood that since the beginning of February, the overall stability rate of Hunan Petrochemical refining sector is better than the headquarters assessment standard, the yield of high value-added oil products has maintained the best level in history, and more than 20,000 tons of high-quality clean oil products such as gasoline, diesel and aviation kerosene have been shipped every day, making every effort to ensure the supply of high-quality oil products in response to the cold wave weather and Spring Festival.
