A compact electrostatic coalescence separation test device and test method

Abstract

The invention discloses a compact type electrostatic coalescence and separation test device and a test method. The device comprises an inlet pipeline, an electrostatic coalescence and separation device, an air exhaust pipeline, an oil drainage pipeline, a water drainage pipeline, a coalescence pipe bracket, a transformer guardrail and a prying chassis, wherein the inlet pipeline comprises an inletpipe, a pump, a bypass gate valve, a main path gate valve, a thermometer, a pressure gauge and a flowmeter; the electrostatic coalescence and separation device comprises a transformer, a primary coalescence pipe, a primary vertical type separator, a secondary coalescence pipe and a secondary vertical type separator; the air exhaust pipeline consists of a first pressure control valve, a second pressure control valve and an air exhaust pipe; the oil drainage pipeline consists of an oil and water interface instrument, an oil level control valve, an oil exit flowmeter and an oil drainage pipe. The device has the advantage that the characteristic of quick coalescence and settlement of water particles in crude oil and the advantage of small land occupation area of vertical type separator are combined by the tubular type coalescence device, so that the transportation, installation, field test and other processes are more convenient.

Description

technical field [0001] The invention relates to the technical field of crude oil dehydration technology, in particular to a compact electrostatic coalescence separation test device and a test method. Background technique [0002] At present, the traditional crude oil dehydration process is "three-phase separator + electric dehydrator", but there are problems such as bulky, low dehydration efficiency, high energy consumption, large amount of demulsifier used, and unstable work, especially not suitable for high water content oilfields , offshore oilfields, green oilfields, and marginal oilfields. Therefore, the high-efficiency and compact crude oil electric dehydration technology with high dehydration efficiency and small footprint has become a development trend. [0003] In the prior art, the combination of the tubular coalescer and the settling device can closely connect the coalescence process and the settling process of the water particles in the crude oil, and effectively...
