Problems solved by technology

However, the absorbent may produce large-scale bad distribution, which is concentrated near the axis. Especially when a large flow of absorbent is required, the separation effect of the liquid distributor is difficult to meet the requirements.

Embodiment

[0050] In this example, the flow rate of the oil gas and air mixture discharged during the storage and transportation of oil products is 300 m 3 / h, the absorption tower diameter is designed to be 80cm. The diameter of the absorbent inlet pipe of the absorption tower is 10cm, connected by an elbow, and its outlet is 16cm away from the center of the tower diameter. The impeller is 6cm below the outlet of the inlet pipe, with a radius of 25cm. The shaft is fixedly connected with the chassis and the conical cover to form a simple fixed axial flow impeller, which converts the flow pressure of the liquid inlet into mechanical kinetic energy and drives the overall rotation of the conical cover of the spray device. . The cone is made of lightweight carbon fiber material and has a height of 50cm. The disc-type hole flow distributor is 100cm away from the top of the tower, the maximum radius of the bottom is 38cm, and there are 50 small overflow holes with a diameter of 32mm, which a...

Abstract

The invention provides an oil-gas adsorption and absorption technical method. Oil gas is adsorbed and absorbed through evaporated oil gas absorption, deep adsorption and desorption of tail gas, rich absorbent desorption and concentration and high-concentration oil gas recycling. Compared with the prior art, the oil-gas adsorption and absorption technical method has the advantages that oil gas can be adsorbed and absorbed as well as desorbed and recycled at the same time; the adaptive capacity is high; the equipment utilization rate is high; the oil-gas adsorption and absorption technical method is convenient and quick; by the adoption of an automatic rotary spraying device, liquid flow at an inlet is dispersed, so that an absorbent is uniformly distributed, channeling is avoided, and poor distribution of the absorbent is eliminated; a gas inlet is immersed below the liquid level of the absorbent, so that part of the oil gas can be absorbed through a liquid stored at the bottom before the oil gas enters a filler and is absorbed, and one more absorption process increases; a baffle can lengthen a path where the gas flows, the space of an absorption tower is fully used, the performance of the absorption tower is developed, the absorption efficiency of equipment and the absorbent is improved, and the oil-gas adsorption and absorption technical method is suitable for application.

Description

technical field [0001] The invention relates to the technical field of oil and gas recovery, in particular to an absorption and adsorption integration method based on a new type of absorption tower and adopting the control operation of the whole process system to absorb and absorb oil and gas and various volatile organic compounds, especially a kind of oil and gas adsorption and absorption process method. Background technique [0002] In the process of exploitation, refining, transportation and storage of petroleum and various chemical products, oil evaporation process will inevitably occur, resulting in oil loss and oil gas pollution. It is becoming increasingly important to control oil loss and vigorously develop and promote oil and gas recovery technology and devices. [0003] Oil and gas recovery technology can be divided into absorption method, adsorption method, condensation method and membrane separation method in principle. Among them, the absorption method has a s...
