Maoming Petrochemical optimizes storage tank maintenance process to achieve cost reduction

In the first half of 2021, the Maoming Petrochemical Refining Division's storage and transportation workshop optimized the maintenance process of the 123# storage tank in the crude oil tank area, reducing the time for the 123# storage tank to produce clear oil and the use of the scaffolding in the tank, and to achieve a total cost reduction Reduce fees by more than 40,000 yuan
.

The Beishan crude oil tank farm in the storage and transportation workshop is the main artery of crude oil transportation in the branch.
It is responsible for receiving crude oil from the port and sending it to the various atmospheric and vacuum units of the refining branch for refining.
It has 15 large crude oil storage tanks with a total tank capacity of 540,000 liters.
The Mi, 123# tank is one of the crude oil storage tanks in Beishan Crude Oil Tank Farm, which has a capacity of 20,000 li
.

At the beginning of 2021, the refining branch upgraded 123#.
The tank started construction in January and was successfully upgraded and put into use at the end of May
.

The workshop technicians optimized the 123# tank cleaning process and took two measures to reduce the production of clean oil.
First, the high-level tank with a low-level oil tank was used for the equipment's refining method, and the higher-level crude oil tank was used.
With 123# tank for refining, one pump is equipped with two storage tanks and 2 different oil types.
The 123# tank is successfully blended to 0.
4 meters lower than the normal cleaning tank.
Secondly, 123# tanks are reduced by optimization.
The two measures combined to reduce the production of more than 1,000 tons of clearing oil by returning the oil to the tank, alleviating the pressure of clearing oil in the plant, and reducing the cost of refining clearing oil by more than 20,000 yuan
.

　　After the 123# tank is overhauled, scaffolding is required for the construction of the tank.
The daily use fee of the scaffold is 2,000 yuan.
The workshop technician supervises the construction throughout the process and optimizes the use time of the scaffold in the tank.
The scaffolding in the tank is used less than 10 days and saves 20,000 yuan Cost
