Abstract

The invention provides a storage tank pipeline gas-liquid separation device. The storage tank pipeline gas-liquid separation device comprises a buffer tank, a liquid inlet pipe, a liquid outlet pipe and a gas outlet pipe, wherein one end of the liquid inlet pipe communicates with the lower portion of the buffer tank, the other end of the liquid inlet pipe communicates with an oil conveying pipeline when in use, one end of the liquid outlet pipe communicates with the lower portion of the buffer tank, the other end of the liquid outlet pipe communicates with a storage tank when in use, the lowerend of the gas outlet pipe communicates with the upper portion of the buffer tank, a floater capable of vertically reciprocating is arranged in the buffer tank, and the floater can seal the gas outlet pipe when moving upwards and can seal the liquid outlet pipe when moving downwards; and the use method comprises exhaust, liquid discharge, gas purging and the like. The storage tank pipeline gas-liquid separation device has the advantages that a liquid medium and a gas medium in a pipeline can be automatically separated during wharf tank field production operation, the liquid medium enters thestorage tank from a liquid conveying pipeline, the gas medium is discharged from the upper portion of the gas outlet pipe, volatilization of liquid is effectively reduced, damage to the floating roofis avoided, resources are saved, environmental pollution is reduced, meanwhile, the structure is simple, and manual operation is not needed.

Description

technical field [0001] The invention relates to a gas-liquid separation device and a gas-liquid separation method. [0002] Specifically, it relates to a storage tank pipeline gas-liquid separation device and a method thereof. Background technique [0003] After unloading the liquid petrochemicals of the tanker, it enters the storage tank in the rear tank area through the transmission pipeline. The length of the transmission pipeline is generally several hundred meters to several kilometers. During the unloading operation, the gas sealed in the pipeline enters from the lower part of the storage tank The storage tank is discharged from the upper part of the storage tank. This process increases the volatilization of the liquid in the storage tank. The liquid filling process of the storage tank is called the large breathing of the storage tank. After the unloading operation is completed, the liquid medium in the pipeline needs to be purged. The purging medium is generally wate...
