Embodiment Construction

[0013] The invention is a device for recovering oil and gas through condensation and absorption. The device is mainly composed of a condenser and an absorption tower, and can recover 99% of the oil and gas by first condensing and then absorbing. The device is easy to operate, and the absorbent used is light diesel oil, which is non-toxic and easy to obtain. The diesel oil after absorbing oil and gas can still be used normally, so desorption is not required. The device can be used in petrochemical plants, large oil depots and gas stations, etc., and has good application prospects. As shown in Figure 1, the device is mainly divided into the following two parts: oil and gas condensation system, absorption tower absorption system. Specifically:

[0014] (1) Use the oil and gas collection system to compress various oil, gas and air mixtures volatilized from the oil storage tank to the oil and gas recovery system.

[0015] (2) Put the oil and gas into the condensing system, starti...

Abstract

A device for collecting and recovering oil gas by condensation and absorption relates to a chemical engineering device and comprises a gas collecting tube, an oil gas storing vessel, a precooler, a deep condenser, an absorption tower, a lean oil pump, an absorbent storing vessel, an oil storing vessel and a rich oil pump; the precooler and the deep condenser together construct a condensation system; the precooler is composed of built-in conduits; the oil gas storing vessel is connected to the left end of the precooler, the right end of the precooler is connected to the top of the deep condenser, the top of the deep condenser is connected to the bottom of the absorption tower, the bottom of the deep condenser is connected to the inlet of a centrifugal pump, the outlet of the centrifugal pump is connected to the oil storing vessel, the absorbent storing vessel is connected to the inlet of the lean oil pump and the outlet of the lean oil pump is connected to the top of the absorption tower. The invention has over 99% oil gas recovery rate, has good economic, environmental and social benefits, and can be applied to aspects of oil gas storage and transport, etc.

Description

technical field [0001] The invention relates to a chemical device, in particular to a recovery and utilization of volatile oil products such as gasoline, oil and gas. It is an oil and gas recovery device integrating condensation and absorption methods. The device can be used in oil and gas storage and transportation. Background technique [0002] Gasoline and other oil products are flammable, explosive, volatile, and easy to lose. The evaporation loss of light oil products such as gasoline is usually a natural loss, and the loss within a certain amount is naturally reasonable. The volatilization rate of gasoline oil and gas is mainly determined by the type of oil storage tank, wind speed, oil level condition, oil storage temperature and pressure of the storage tank. During the process of filling and transferring gasoline, the molecular movement is intensified, causing a large amount of oil and gas to volatilize. If the volatilized oil and gas are not properly treated, it wi...
