Embodiment Construction

[0051] Embodiment of the present invention is described below in conjunction with accompanying drawing, embodiment does not constitute limitation of the present invention:

[0052] Combine below figure 1 and figure 2 Embodiments of the present invention are described, and embodiments do not constitute limitations of the present invention:

[0053]An associated gas recovery compressor, characterized in that it includes an air storage chamber, inside the air storage chamber there is a blowing piston, and two one-way valves are distributed on the air storage chamber, which are respectively air inlet one-way valves 14 and exhaust port check valve 15. Therefore, the blowing piston can realize the one-way entry and exit of gas, and then complete the pumping effect; the power of the blowing piston described here can be various, and some technical solutions that can be realized are enumerated below, and similar technical solutions are also described in this article. within the sco...

Abstract

The invention relates to the field of machinery, in particular to a method for removing wax deposition dirt of an oil conveying pipeline and an associated gas recycling compressor. The method comprises the following steps that associated gas is extracted up through devices under the condition of good sealing performance, and the associated gas is fed into a pipeline conveying liquid petroleum, wherein the devices include a gas storage cavity, a pumping and blowing piston is arranged inside the gas storage cavity, two one-way valves are distributed on the gas storage cavity, and the two valves are a gas inlet one-way valve (14) and a gas outlet one-way valve (15); the associated gas is fed into the oil conveying pipeline after being compressed by the utilization of the vertical movement of the pumping and blowing piston; gas and liquid moving in the oil conveying pipeline generate an eddy together, therefore, relative constituents of fluid cannot be separated out easily, gas will be broken and burst constantly during the conveying, and oil-gas mixture in the pipeline flows in the eddy mode, so that dirt is not formed, and wax deposition and scale deposition are reduced. Meanwhile, sticky wax dirt falls down due to the impact of bubbles.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a method for removing wax deposits on oil pipelines and a compressor for recovering associated gas. Background technique [0002] The main solid substances in crude oil are alkanes containing 18-64 carbon atoms, that is, paraffin, and sulfate or carbon salts of barium, strontium, magnesium, and calcium. Due to the influence of factors such as changes in transportation temperature and long transportation time, solid or slushy dirt substances gradually accumulate on the inner wall of the transportation pipeline, causing the crude oil transportation volume to gradually decrease or block, resulting in energy waste, environmental pollution, affecting operation, and increasing operation. cost etc. [0003] There are two main reasons for fouling inside oil pipelines. [0004] (1) Paraffin, the main solid in crude oil, has a melting point of 40-60°C. During the long-distance transportation of ...
