There is a strong odor of oil and gas when water is removed from oil tanks; does anyone have any good solutions?

Water is being removed from the oil tanks in the intermediate tank area. Due to the evaporation of oil and gas – especially in gasoline storage tanks – there is a strong unpleasant odor at the dehydrating tank area, which does not meet environmental standards. Does anyone have any good solutions?
We extended the cut-off point to the drain outlet and sealed the surrounding area with felt.
Currently, the control of VOCs is mainly achieved through the use of pool covers and activated carbon adsorption to reduce volatilization and to handle these substances through adsorption
How can we ensure an effective cut-off when sealing the drain outlet? We have used this method before, but the problem of oil carrying water occurred
The poster can choose an automatic water cut-off device
How can one observe signs of dehydration? I’m a new employee and seeking advice
We have encountered the problem where, due to the accumulation of impurities, the dehydrator is unable to distinguish properly, resulting in oil being carried along with water
On our end, we carry out centralized treatment in a sealed environment; after dehydration for a while, the process is paused so that manual measurement can be done. (The outlet valve of the tank is located at a relatively high position, so the water isn’t completely dehydrated – about 2-4 centimeters of water remain.) Since the turnover rate isn’t very high, this method remains effective:lol
Manual cutting of water at the site is carried out, with regular sampling for observation. Before cutting off the water, the water level is measured first; during the cutting process, the control room keeps a close eye on the decline in the liquid level in the storage tank. It is not necessary to remove all the water at once – 2-3 centimeters should be left uncut, which helps prevent oil from being removed along with the water.
