Description :

pressure vesselIt is a widely used liquid pressure vessel in the chemical industry. There are three types of pressure vessels: oil-water two-phase pressure vessels, oil gas water three-phase pressure vessels, and the widely used variable pressure liquid level control pressure vessels. Today, we will introduce to you the variable pressure liquid level control container.

　　Variable pressure liquid level control pressure vessels control the separation of liquids by controlling the changes in pressure inside the container. The variable pressure liquid level control pressure vessel utilizes an internal float liquid level controller to drive two regulating valves. One regulating valve controls natural gas, and the other controls crude oil, thus achieving joint regulation of valves at the crude oil and natural gas locations.

　　.

　　When the float rises, the connecting rod mechanism reduces the opening of the air regulating valve and increases the opening of the oil regulating valve; On the contrary, when the float descends, the connecting rod mechanism will increase the opening of the air regulating valve and decrease the opening of the oil regulating valve.

　　By changing the opening of the regulating valve of the pressure vessel by adjusting the variable pressure liquid level, the relative flow rate of natural gas and crude oil can be changed, thereby controlling the liquid level of the pressure vessel.

　　The variable pressure liquid level control method does not perform constant pressure control on the separator, and the pressure inside the pressure vessel is the sum of the pressure at the natural gas or liquid location and the pressure difference before and after the natural gas regulating valve or liquid regulating valve. When the gas and liquid volumes, as well as the downstream pressure of the separator, change, the pressure of the separator also changes, so this control method is called variable pressure control.

　　The application of pressure vessels can bring great convenience to industries such as chemical engineering and petroleum refining. Pressure vessels can effectively separate gases and liquids through certain methods, playing a significant role in the separation of crude oil.
