Multi-fuel supply system for main power station on offshore platform

Abstract

The invention discloses a multi-fuel supplying system of a main power station of an offshore platform. The multi-fuel supplying system of the main power station of the offshore platform comprises a natural gas supplying system and a diesel oil supplying system. The multi-fuel supplying system further comprises a crude oil supplying system. The crude oil supplying system comprises a crude oil setting tank, a crude oil centrifugal washing system, a crude oil flashing system and a crude oil daily use tank. The crude oil setting tank is communicated with the crude oil centrifugal washing system. A front crude oil chemical adding system is connected between the crude oil setting tank and the crude oil centrifugal washing system. The crude oil centrifugal washing system is communicated with the crude oil flashing system and the crude oil flashing system is communicated with the crude oil daily use tank. A fuel oil tank is used for providing fuel for the main power station of the offshore platform. A crude oil treatment subsystem is additionally arranged on the basis of a common double-fuel treatment process, the requirement for the fuel when the multi-fuel main power station is normally operated can be satisfied, it is guaranteed that the main power station can reliably and safely work through the self-produced fuel of an oil field, influence caused by fuel restriction is reduced in the offshore oil field development process, and reliable electrical energy can be provided for the platform.

Description

Technical field [0001] The present invention relates to the technical field of multi-fuel power generation, in particular to a fuel supply system for an offshore platform main power station, in particular to a multi-fuel supply system for an offshore platform main power station. Background technique [0002] In the development of the offshore oil industry, as the degree of oilfield development continues to deepen, offshore oil's requirements for main power stations are getting higher and higher, and the conventionally used main power stations can no longer meet the needs of oilfield development. For example, in the development of an oil field in the Bohai Sea, due to the large self-consumption scale of the oil field, the self-produced gas cannot meet the requirements of the power generation scale, and the surrounding oil fields have no fuel gas source to rely on. Therefore, when selecting and designing the main power station, The platform using conventional dual fuel (diesel and ...

[0002] In the development of the offshore oil industry, with the deepening of oilfield development, offshore oil has higher and higher requirements for the main power station, and the conventionally used main power station can no longer meet the needs of oilfield development

For example, in the development of an oilfield in the Bohai Sea, due to the large self-consumption scale of the oilfield, the self-produced gas cannot meet the requirements of the power generation scale, and the surrounding oilfields do not have fuel gas sources to rely on, so when selecting and designing the main power station, the offshore The platform adopts conventional dual fuel (diesel and natural gas or diesel and crude oil) main power station will not be able to meet the requirements of the oil field
