Since the beginning of summer, Anqing Petrochemical's storage and transportation department has tailored a number of safety protection measures based on the characteristics of various storage tanks to ensure that more than 160 storage tanks are safe in the summer
.
After heavy rains in summer, the temperature of the oil tank often drops sharply, and accidents such as deflation of the oil tank are prone to occur.
For this reason, they have formulated a daily inspection and maintenance system for the breathing valve of the oil tank to ensure the normal operation of the breathing valve
.
For storage tanks equipped with nitrogen seals, the pressure control system for nitrogen supplementation is intact
At the same time, a comprehensive maintenance test was carried out on the spray cooling facilities of each storage tank, and the pressure and temperature control of the liquid hydrocarbon tank farm were carried out in strict accordance with the process card, and the cooling spray was put into use in a timely manner
.
Perform routine maintenance on the safety accessories of atmospheric storage tanks, pressure vessels and other equipment to ensure the display, alarm, and interlocking of liquid level, temperature, pressure, flow and other parameters, as well as the input of breathing valves, pressure relief manholes, and safety valves.
During the operation, the operator strictly controls the speed of receiving and disbursing materials in accordance with the regulations to ensure that the pressure vessel and pressure pipeline are not over-temperature and over-pressure
.
Conscientiously implement pipeline pressure relief management regulations, especially gasoline and hydrocarbon media pipelines, and resolutely prevent accidents caused by over-temperature and over-pressure
