Abstract

The invention provides a hydrocarbon steam recovery device, and relates to the field of petroleum industry. According to the hydrocarbon steam recovery device, a dehydration tank is used for removingpart of water in crude oil by means of sedimentation; a purification tank is used for purifying the crude oil output by the dehydration tank; a buffer tank is communicated with the tops of the dehydration tank and the purification tank, and is used for carrying out gas-liquid separation on hydrocarbon steam output by a gas conveying pipe so as to separate the hydrocarbon steam into liquid and gas;a liquid storage tank is communicated with the buffer tank, and is used for storing the liquid; a gas extraction device is communicated with the buffer tank and the liquid storage tank, and is used for conveying the liquid and the gas to the outside. When the hydrocarbon steam recovery device is in use, the hydrocarbon steam is firstly subjected to initial separation of the buffer tank, and thenenters the liquid storage tank; a two-stage light hydrocarbon storage way is adopted, so that the problem unstable pressure of an oil storage tank is solved while the yield of light hydrocarbon is increased.

Description

technical field [0001] The invention relates to the field of petroleum industry, in particular to a hydrocarbon vapor recovery device. Background technique [0002] In the process of oil collection, transportation and storage, it is necessary to use various large containers to load crude oil. For various large containers, for the sake of safety and stress, they can only be stored under normal pressure, and the large containers are communicated with the outside world to keep the pressure difference between the inside and outside of the storage tank basically zero. However, due to the various types of components in crude oil, a considerable part of light oil volatilizes from the original pool during storage. In order to keep the pressure of the storage tank from increasing, it must be discharged into the atmosphere. Depending on the nature of crude oil and the gathering and transportation process, the amount of this loss ranges from one ten-thousandth to one percent. This no...
