The process I designed includes: 1. Tank filling process (with remote-controlled valves; interlocks are in place – when the liquid level in the tank reaches a high level, the inlet valve of another tank is opened while the inlet valve of this tank is closed). 2. Tank operation process (with remote-controlled valves; when the liquid level in the tank is very low, the pump is stopped and the valves are closed). 3. Vapor release from the top of the tank process (an alarm is triggered when pressure is high, causing the spray water system to activate; interlocks ensure that this valve opens, and if pressure remains high, the safety valve activates). Condensers are also used in some cases, but their effectiveness is poor due to the high flow rate. 4. Water injection process (to prevent leaks at the flanges at the bottom of the tank). It should also be noted that the flanges connecting to the spherical tank must have a pressure rating of at least PN2.5, and attempts should be made to minimize the number of openings at the bottom of the tank. 1 is best.
