Problems solved by technology

The high-speed electric desalting equipment achieves the goal of using a smaller electric desalting tank and achieving a larger processing capacity. However, due to the structural defects of the high-speed electric desalting equipment, it can only process light crude oil, and the treatment of slightly heavy crude oil contains Salt cannot meet the required technical indicators, let alone handle heavy crude oil, and some devices cannot even send electricity for desalination
In recent years, Howe-Baker Engineers Ltd. of the United States has developed heavy oil electric desalination equipment that can handle relative density of 0.9861g / cm 3 heavy oil, but diluent must be added, which does not fundamentally solve the problem of direct desalination of heavy oil

Abstract

The invention discloses an updated heavy oil desalting and dewatering device. The device is composed of an electrical desalting tank, a transformer and a high-voltage electronic joint device, an oil inlet main pipe, oil inlet branched pipes and flow regulating valves, wherein an upper electric field in the electrical desalting tank consists of at least one electric field unit and adopts the multiple electric field distribution technology of single power supply, each electric field unit consists of a drip tray, a live electrode, a grounding electrode, an oil inlet nozzle, a backwashing device and a down pipe; and a fast dewatering and draining device consists of a V-shaped drip tray, a backwashing device and a down pipe, a backwashing nozzle and the bottom surface of the drip tray forms an inclination, the top of the down pipe is connected with the bottom of the drip tray, and the other end is inserted in the water layer of the electrical desalting tank. The field intensity of the upper electric field of the device is optimized, fast dewatering and draining can be ensured, the desalting efficiency is increased; and the updated heavy oil desalting and dewatering device is suitable for the deep desalting and dewatering treatment of crude oil, particularly heavy crude oil, fuel oil and other heavy oil products.

Description

technical field [0001] The present invention relates to heavy oil pretreatment equipment, in particular to an equipment for deep desalination and dehydration treatment of heavy crude oil, fuel oil and other heavy oil products, which can be widely used in petrochemical, oil refining, gas turbine power plants, etc. Enterprise's heavy oil pretreatment. Background technique [0002] With the continuous deepening of crude oil exploitation around the world, the trend of crude oil becoming inferior and heavy becomes more significant. According to the USGS report, among the unexploited oil resources, heavy oil (API≤20°) and extra heavy oil (API≤10°) resources are twice as much as light crude oil resources. From 2000 to 2009, the production and processing volume of heavy oil among all kinds of crude oil in the world has exceeded 13%. With the increasing proportion of heavy oil, the value of the development and utilization of heavy oil is highlighted. The technology development of h...
