Oil vapor recovery units used in refineries and oil depots are in hazardous environments with flammable and explosive gases and must meet explosion-proof requirements. There are four main oil vapor recovery process technologies: absorption, adsorption, membrane separation, and condensation.。

The VOCS analyzer is the core device. By centrally installing the VOCs cabinet and other non-explosion-proof electrical components inside a pressurized explosion-proof station, safe operation can be achieved in compliance with explosion-proof requirements.。

Pressurized explosion-proof stations only need to maintain the positive pressure state of the enclosure and the cleanliness of the gas, making inspection, maintenance, and troubleshooting convenient.。adoptPositive PressureExplosion-proof Station HouseWhen，LocationsWithElectricApplianceallUpWithAccordingOrdinaryElectricAppliance safetyStandardSelectadopt，ItsoperationEnvironmentsafety、cleaning、temperatureSuitableIn,ElectricAppliancefunction的reliablePerformanceGreaterWithsafeguard。

Pressurized explosion-proof stations create a safe micro-environment within a hazardous macro-environment. The enclosure is made of stainless steel plates with a sealed overall structure, unaffected by sun and rain and resistant to corrosive gas erosion.。The safety and explosion-proof control points of a pressurized explosion-proof station consist of only three components: the pressurized explosion-proof system, the explosion-proof power distribution system, and the combustible gas detector.。

Before the oil vapor recovery system is started, the pressurized explosion-proof station is first purged with fresh air so that both the pressure inside the enclosure and the cleanliness of the space gas meet explosion-proof safety requirements. After confirmation by the combustible gas detector, power is supplied to the control cabinet of the oil vapor recovery system and the VOCS cabinet, and the oil vapor recovery system is started according to the designed procedure.。
