Generally, it is an automatic control, high-pressure water jet, and the work includes five subsystems: High-pressure cleaning, liquid pumping and water pumping, automatic control, long pipe control and respirator protection, exhaust gas purification, the core is the high-pressure cleaning system, including water supply device, high-pressure pump, automatic pressure regulating device, high-pressure cleaning machine, three-dimensional tank washer and three-dimensional crane part, water supply device The water supply is pressurized by a high-pressure pump to 20-30MPa, and the water is sprayed onto the inner wall of the tanker through a high-pressure cleaning machine and a three-dimensional tank washer, which has the effect of striking, eroding, cutting, and eradicating residual materials and rust on the inner wall of the tanker to achieve the purpose of cleaning.
Domestic tank washing stations are basically set up in the refinery system. There is probably no standard for this in the domestic petroleum industry. You can refer to the "Petroleum Product Packaging, Storage, Transportation and Delivery Acceptance Rules" SH 0164-1992 (1998). For the specific tank washing process, the high-pressure water jet currently used is said to be used well. You can check it online.

What the poster said is too vague. For railway tank cars containing refined oil, it is usually enough to simply suck out the oil at the bottom of the tank. ； The type of solvent oil depends on the user's needs. Generally, it just sucks the base oil cleaner. ； If users have very high quality requirements, they need to perform special cleaning and use water, steam or other solvents to clean the inside of the tank. The most important thing still depends on the customer’s requirements for product quality.
Do you have any specific processes and control systems to share?
There is a special SH standard number, but I forgot about it.
