100ft diameter API 650 cylindrical liquid-storage tank

Under the condition of static storage without receiving and sending operation, the temperature of gas space, evaporation rate, depth and pressure of vapor in the API 650 cylindrical liquid-storage tank will change with the change of temperature and pressure in a day. The oil loss caused by the process of discharging oil vapor and inhaling air gas is called "small breathing" loss, which is also called static storage loss of oil tanks.

Combination of Design Loads
The inner tank API 650 cylindrical liquid-storage tank shall be designed for the most critical combinations of loading that result from internal pressure and liquid head, the static insulation pressure, the insulation pressure as the inner tank expands after an in-service period, and the purging or operating pressure of the space between the inner and outer tank shells, unless the pressure is equalized on both sides of the inner tank.

The API 650 cylindrical liquid-storage tank external floating roof tank of API 650 tank has many advantages, and its application range is more and more wide. It is a kind of storage tank with a bright future. The well-designed internal floating roof tank of API 650 tank is the best and least investment method to control evaporation loss of API 650 cylindrical liquid-storage tank Fixed roof tank.
