The invention discloses an ocean platform crude oil flash evaporation system based on an ejector. The ocean platform crude oil flash evaporation system comprises a crude oil flash evaporation system and a waste gas treatment device, the crude oil flash evaporation system comprises a flash evaporation tank, the ejector, a condenser and a three-phase separator; the flash evaporation tank is used forgasifying and separating the crude oil subjected to heating dehydration through generated negative pressure, the separated light crude oil is inputted into the three-phase separator, and the heavy crude oil is inputted into the storage tank; the three-phase separator is used for carrying out gas-liquid separation on the condensed flash steam and separating non-condensable gas from condensate oil;and the waste gas treatment device is used for treating waste gas generated by the diesel engine to remove pollutants. Waste gas generated after combustion treatment of the diesel engine is compressed through the compressor and flows into the ejector to serve as working fluid, crude oil flash evaporation operation is conducted under the action of negative pressure generated by the ejector, the initial cost of the device can be reduced by about 50% after the ejector is used for replacing a vacuum pump set, and meanwhile the waste gas generated after combustion is utilized, and energy loss andenvironmental pollution are reduced.
Description
technical field [0001] The invention relates to an offshore platform crude oil flash evaporation system, in particular to an injector-based offshore platform crude oil flash evaporation system. Background technique [0002] All offshore platforms use self-provided power stations to provide electricity for the platform. Crude oil power generation is a power station form commonly used by offshore platforms, which can not only reduce the flash point of crude oil, but also provide fuel for power stations on offshore platforms. Negative pressure flash distillation is currently the most widely used and mature crude oil stabilization method in China. Under the condition of negative pressure, the properly heated crude oil is flashed and degassed to recover the low-carbon hydrocarbons in the crude oil and achieve the purpose of stabilizing the crude oil. In this process, a vacuum pump group is needed to meet the pressure difference and displacement. The vacuum pump group usually c...
