Abstract

The invention provides an industrial treatment method for oil field waste. The industrial treatment method for oil field waste comprises the following steps: carrying out sampling analysis on the oil field waste, preheating to 80-300 DEG C by using high-temperature steam or conduction oil, then carrying out microwave pyrolysis treatment, controlling pressure at minus 5000 to minus 100 Pa, thus obtaining solid treatment substances and gas, condensing, separating and purifying the gas, and finally recycling so as to obtain water, oil and non-condensable gas. An industrial treatment device for oil field waste comprises a feed hopper, a dryer, a microwave heating cavity, a microwave generator, a heating device and a condensation separation purification device, wherein the feed hopper is connected to the dryer which is connected to the microwave heating cavity, a steam or conduction oil outlet of the heating device is connected to a steam or conduction oil outlet of the dryer; gas outlets of the dryer and the microwave heating cavity are connected to the condensation separation purification device; the microwave generator is connected to the microwave heating cavity. The industrial treatment method and the industrial treatment device have good treatment effects, high utilization rate of energy sources and good economical efficiency.

Description

technical field [0001] The invention relates to the field of oilfield waste treatment, in particular to an industrial treatment method and device for oilfield waste. Background technique [0002] Oilfield waste usually refers to cuttings produced during drilling, water-based mud and oil-based mud, oily sludge and sediment produced during oil production and oil well operations, crude oil-contaminated soil, and crude oil during storage in storage tanks. Tank bottom sediment, etc. In addition to certain petroleum substances, oilfield waste also contains a large amount of benzene series, phenols, anthracene, pyrene and other toxic substances, salts and heavy metals such as copper, zinc, chromium and mercury. These oilfield wastes are not easy to deal with. It takes hundreds of years to completely decompose under natural conditions. Not only does it directly occupy land and space, but it also seriously pollutes air, soil and groundwater, restricting the production and developmen...
