China Petrochemical News Network News Qilu Petrochemical Refinery firmly grasped the golden period of efficiency creation, optimized product structure, reduced production costs, produced more high-value-added products, and continued to optimize efficiency and create benefits
.
From January to July this year, a total of 6.
Keep a close eye on crude oil entering the factory and do a good job of material balance
"January to July is the golden period for crude oil processing in refineries.
In order to fully complete the crude oil processing tasks, we closely monitor the crude oil entering the plant and the material balance of each device to ensure that the devices are operating at full capacity
.
" Source introduction
In the first half of the year, affected by the regional shutdown of the second chemical fertilizer plant for maintenance, the first hydrogen production plant started up as planned, which satisfies the balance of the hydrogen pipeline network and avoided the load reduction operation of the secondary plant
.
At the same time, the refinery is also actively coordinating the sales, storage and transportation department to do a good job in the export of propylene for the second fertilizer plant to ensure a smooth future for the refined products
In order to pursue the highest crude oil processing volume and the corresponding material balance, the oil type and quantity of the crude oil purchased according to the product delivery conditions were reversed before the major overhaul, and the crude oil procurement plan was docked with the company's planning and operation department many times
.
The factory actively optimizes and adjusts the product structure, increasing the number of products shipped from all aspects to avoid blockage
.
First, use the SSOT device to crack diesel into naphtha, jet fuel, liquefied petroleum gas, etc.
Refined optimization operation to solve production problems
"Now that the device is operating at full load, we always observe the indicators, adjust the amount of water injection and the amount of demulsifier injected, to ensure that the salt content after removal is qualified, to prevent corrosion of the top of the atmospheric tower, to ensure the smooth operation of the electric desalination tank, and to avoid secondary processing.
The influence of the installation
.
” said Zhang Yong, deputy director of the joint installation workshop of the plant
Electric desalination is the first step of the atmospheric and vacuum unit for oil refining, which affects the subsequent work of the unit.
The plant timely adjusted the process to improve the operation level and ensure the full-load operation of the fourth atmospheric and vacuum unit
.
"We always pay attention to the current, by reducing the water injection or increasing the water cut to stabilize the current; and check the burner burning situation at any time, and make small and stable adjustments to the burner to ensure that the entire furnace flames are uniform and the flame burns evenly to avoid local high temperature points
.
" Wu Wanchun, the fourth atmospheric and vacuum internal operator, emphasized how to do a good job in the operation of the heating furnace
At the same time, in view of the high load of the fourth atmospheric and vacuum unit and the possibility of flange leakage, the operator strengthened inspections and carefully checked each sealing surface, and found hidden dangers to be dealt with in time
.
Strengthen the upper limit of responsibility operation card
"Due to the limited amount of residual oil sent out, although the residual oil control valve is fully open, it still becomes a bottleneck to further increase the load.
The operator adjusts the previous process to control the liquid level and always maintains the maximum amount of residual oil sent out
.
" Said Wang Jun, deputy director of the plant's third atmospheric vacuum workshop
Heating furnace and residual oil delivery are the two bottlenecks that increase the load of the third atmospheric and vacuum unit.
The plant actively responded by transporting the maximum amount of asphalt to the asphalt workshop for delivery; at the same time, it will do a good job in switching and adjusting Kuwait crude oil and low-sulfur crude oil.
, The operator always keeps an eye on the data changes and stabilizes the card edge operation of the top pressure of the primary distillation tower and the atmospheric and vacuum tower of the heating furnace
.
"The card side operation puts forward higher requirements for the operators.
It is necessary to watch the meter carefully, strengthen the inspection, and do a good job of the sideline distillation of the atmospheric tower and the vacuum tower, and control the indicators to ensure the smooth operation of the device
.
" Third Wang Hongbin, the head of the third shift of the process of the atmospheric vacuum workshop, said, "Now that the benefits are good, it is necessary to ensure product quality, strengthen inspections, hidden danger investigation, and high-load operation of the device.
Under the premise of ensuring product quality and process parameters, the refinery will do a good job of switching crude oil based on market conditions and demand dynamics, increasing the amount of crude oil processed, and creating more benefits
