Oil and gas recovery in storage and transportation tank areas
Thread Content
May I ask, after installing a roof vapor recovery system on the storage tank, what is the concentration of vapor and oil that escapes from the roof during normal operation or under normal conditions, up to the inlet of the vapor recovery equipment? How much oil and gas can 1 unit of oil and gas recovery equipment with a capacity of 500 m3/h recover in 1 hour? What is the profit after deducting costs such as electricity fees?
The amount of oil that can be recovered is related to low ambient temperatures, the volatility of the oil, and the efficiency of the recovery equipment. Since many factors and conditions are involved, it’s not possible to determine the exact amount of oil that can be recovered. We have a oil and vapor recovery system with a capacity of 400 m3/h, utilizing a three-stage cooling and adsorption process; in summer, the daily recovery amount is between 30–50 KG, while in winter it’s around 3–5 KG per day.
Thank you. It seems that there will definitely be losses; the main issue is environmental protection

I would like to ask how the recovery rate of non-methane hydrocarbons, which is said to be greater than 97% for the oil and gas recovery systems in tank areas, is determined

The final treatment result provided by our manufacturer is a removal rate of 95%; due to the small size of the exhaust outlet, it is not possible to conduct testing
How can it be profitable? The annual cost for electricity and lighting alone is 700,000–800,000 yuan; adding the costs of activated carbon filtration, disposal of hazardous waste, equipment maintenance, and personnel expenses, the total operating investment amounts to at least 1 million yuan. If the initial treatment concentration is 10,000 Mg/m³ and the exhaust concentration is 50 mg/m³, the annual recovery amount shall be ≤ 40 t ； The price of oil is 5,000 yuan per ton, so it’s only 200,000 yuan in total. This is still under the assumption of exaggerated returns.
It’s probably mainly due to considerations of safety and environmental benefits. Accidents caused by the evaporation of oil and gas can result in costs in the hundreds of thousands; failure to meet standards regarding the control of environmental pollutants also leads to fines amounting to hundreds of thousands
The removal efficiency can be calculated by using the ratio of the total non-methane hydrocarbon concentrations at the inlet and outlet of the oil and gas recovery equipment, that is, those at the front and back
Which company’s technology are you using? Can the emission concentration meet the standards?
