Description

Technical Field

[0001] The utility model relates to the technical field of three-phase separators, in particular to a heatable three-phase separator. Background Art

[0002] Crude oil contains water and natural gas after being extracted from oil fields and oil wells. Before transportation, it needs to be separated using a three-phase separator. The main function of the three-phase separator is to separate the oil, gas and water phases in the formation fluid and accurately measure the output of each part. This equipment plays an important role in the development and production of oil and gas fields, providing a strong guarantee for the accurate measurement and efficient utilization of oil and gas resources.

[0003] According to the different structural forms, three-phase separators are usually divided into three types: vertical, horizontal and spherical. Among them, the horizontal three-phase separator is widely used in oil fields due to its compact structure, easy transportation, simple operation and maintenance. In current use, the mixed liquid enters the separator through the feed port. Due to the special design of the internal structure, substances of different densities are gradually separated during the flow process, and the lighter gas gathers at the top of the separator and is discharged through the gas outlet; the oil is deposited at the bottom of the separator under the action of gravity, while the liquid is located between the two and is discharged through the liquid outlet. In the oil-water separation process, the oil-water mixture collides and agglomerates with each other under the action of the coalescing plate to form larger oil droplets and water droplets, thereby realizing oil-water separation. The separated gas is further purified by the vortex eliminator and the demister and then discharged from the gas outlet.

[0004] However, in the above-mentioned prior art, the mixed liquid medium to be separated cannot be heated to the required temperature, resulting in slow efficiency of the medium separation operation. Utility Model Content
