● The system collects the leaked oil and gas in the storage tank, and controls the oil and gas pressure in the gas phase space to realize the zero emission opening of the breathing valve, so as to achieve zero VOCS pollution emission of volatile oil and gas in the storage tank.
● The system adopts respiratory suppression, purification separation and active protection technology to realize the recycling of the whole process of collecting oil and gas, and completely realize zero pollution emission.
● The system can automatically monitor the use of the tank top breathing valve, when the breathing valve seal failure, the system automatically alarm.
● The system automatically detects the oil and gas concentration, oxygen concentration, explosion upper limit and lower explosion limit of volatile oil and gas, and comprehensively monitors the safety state of the storage tank.
● The system does not need instrument wind, nitrogen wind and other public works, the total power consumption is less than 5KW, simple maintenance, low operating cost.
● The system realizes automatic unattended operation and remote maintenance functions.
● The system can be installed when the tank is in service with oil.
● The system is suitable for fixed roof tank, internal floating roof tank and oilfield settling tank of crude oil, steam coal fuel, benzene, methanol and other petrochemical industry.
● The system is designed and manufactured according to the explosion-proof design specification to meet the explosion-proof requirements.
