Precautions for LPG storage tanks

LPG storage tanks include compressed gas or liquefied gas storage tanks, etc. The LPG storage tanks can be divided into fixed volume storage tanks and movable volume storage tanks according to whether the volume of the pressure vessel changes or not, and large fixed volume LPG storage tanks The cans are made spherical and the small ones are made cylindrical. The active volume storage tank is also called low-pressure gas storage tank, commonly known as a gas cabinet. Its geometric volume can be changed, tightly sealed, without leakage, and it has the function of balancing the air pressure and adjusting the gas supply. The pressure generally does not exceed 60MPa.

Precautions
Safe operation of LPG storage tanks To prevent overtemperature and overpressure phenomena in LPG storage tanks, the operating pressure and operating temperature should be controlled. The reasons for the over-temperature and over-pressure of the liquefied gas storage tank are as follows:

(1) Operation error
In order to prevent operation errors, the key operating device should be listed, and the opening and closing direction, opening and closing status, and precautions of the valve, etc. should be indicated on the gas storage tank plate with obvious marks or words. (2) Excessive filling of liquefied gas
Measures to prevent overfilling include: filling strictly according to the prescribed storage capacity, and finding that the pressure vessel is overfilled, should immediately try to withdraw the overfilled volume; all instruments used for filling LPG tanks must be regularly inspected, liquid level gauge It should be rinsed regularly; if there is residual liquid in the container, it should be included in its filling volume, and its weight cannot be ignored; when the surrounding temperature increases, spray cooling should be performed.
