Abstract

The invention provides a movable energy self-sufficient device for an oil gas heavy hydrocarbon recovery system. The heavy hydrocarbon recovery system comprises a compressed oil gas storage tank, a carbon sulfur gas separation device, a carbon sulfur gas storage tank, a hydrocarbon distillation tower, a low carbon gas storage tank, a heavy hydrocarbon storage tank, a gas engine, a refrigerator and a heater. The pressurized oil gas in the compressed oil gas storage tank firstly enters into the carbon sulfur gas separation device, and the carbon sulfur gas in the oil gas is firstly separated and released as an auxiliary fuel needed in engine work; the low carbon gas in the oil gas is distilled and separated through the hydrocarbon distillation tower and is taken as a main fuel needed in the engine work; the electricity generated by the gas engine is taken as all engine sources of the heavy hydrocarbon recovery system. According to the movable energy self-sufficient device provided by the invention, the energy of the recovery system is self-sufficient, after the device is used, the heavy hydrocarbon generated in the oil gas is recycled, the low carbon waste gas is recycled, the environment is purified, and the waste gas can generate benefit.

Description

technical field [0001] The invention relates to an energy supply device for waste gas removal from oil and gas produced in an oil field and a heavy hydrocarbon recovery system, especially an energy self-sufficiency device. Background technique [0002] During the exploitation of oil, coal fields, and natural gas fields, some oil and gas will be produced. The oil and gas contain a large amount of methane, carbon dioxide, hydrogen sulfide, water vapor, and many heavy hydrocarbons (referring to hydrocarbons with more than 3 carbon atoms in the molecule. class) material composition. [0003] Usually this kind of oil and gas is not recovered, and it is directly vented, which not only wastes energy, but also pollutes the environment. [0004] Now there are some oil fields and coal fields that recycle the oil and gas. However, recycling requires a lot of heavy equipment and consumes a lot of electricity in the power grid. The construction period is long and uneconomical. [000...
