Embodiment Construction
[0019] One embodiment of the present invention provides an environmental protection device for waste steam recovery and utilization of oil collection tanks. The high-temperature waste steam from the buffer tank is condensed through the spray tower, and the non-condensable gas is separated, and the non-condensable gas is further processed. The device performs harmless treatment of non-condensable gas to achieve the technical effect of purifying waste gas. At the same time, in the oil-water separator, the high-temperature water condensed in the spray tower is separated from oil and water, and the oil in it is further recovered. At the same time, part of the separated high-temperature clean water is used to realize the technical effect of heating cycle or external heat mixing, and the rest Then it is sent to the air cooler for cooling, and after cooling to an appropriate temperature, it is sent back to the spray tower for use as waste steam cooling water. In this way, the complet...

The invention discloses an environmentally-friendly recycling device for exhaust steam of a gathering tank, and belongs to the technical field of oil exploitation. The device is characterized in that a spray tower is utilized to perform cold and heat exchange for high-temperature exhaust steam and separate non-condensate gas; then an oil-water separator is used for separating the non-condensate gas into an oil part and a water part; finally the water part is recycled to the spray tower under the effects of a circulating water pump and an air cooler, and at the same time the oil part is recovered; the heat of the exhaust steam is outwards conveyed to mix and heat. With the adoption of the device, the oil gas resource is recovered, and the technical effect of reducing the pollution of the exhaust steam to the environment is reduced.
Description
technical field [0001] The invention relates to the technical field of petroleum exploitation, in particular to an environmental protection device for recycling waste steam from an oil collection tank. Background technique [0002] The world's heavy oil resources are extremely rich, and its geological reserves far exceed the reserves of conventional crude oil, while my country's heavy oil reserves rank seventh in the world. [0003] At present, the thermal recovery method is generally adopted for the recovery of heavy oil, which utilizes the mechanism of viscous reduction of heavy oil heating, the oil displacement mechanism of oil layer thermoelastic energy release, and the dilution and miscible flooding effect of steam on heavy oil distillation, cracking and emulsification. A large amount of steam is injected into formation crude oil to improve the seepage capacity of heavy oil and realize the industrialized exploitation of heavy oil. [0004] But, inventor finds in daily ...
