Visualization device for scaling and corrosion of tower top system of crude oil distillation device

Abstract

The invention belongs to the technical field of corrosion management and control of an oil refining device, and discloses a visualization device for scaling and corrosion of a tower top system of a crude oil distillation device. The visualization device includes a temperature sensor C, a high-magnification camera, and a computer. The visualization device is arranged on a bypass simulation oil andgas pipeline of the tower top system, and the tower top system includes a distillation tower, a crude oil-oil and gas heat exchanger, a primary tank, an air cooler, a water cooler, a secondary tank and a product pump connected in sequence. The pipeline between the distillation tower and the crude oil-oil and gas heat exchanger is an oil and gas volatilization pipeline, the bypass simulation oil and gas pipeline is a branch pipeline introduced by the oil and gas volatilization pipeline, and an auxiliary tank and an injection pump are located on the oil and gas volatilization pipeline at the downstream of the distillation tower. The device is practical, the process is simple, and the operation is convenient. Visual automatic monitoring can be realized for the corrosion process of the tower top system of the distillation device, and visual simulation of corrosion and scaling of the volatilization pipeline of the tower top system can be realized.

Description

technical field [0001] The invention belongs to the technical field of corrosion management and control of oil refinery equipment, and in particular relates to a visualization device for fouling and corrosion of a tower top system of a crude oil distillation equipment. Background technique [0002] Due to the complexity of the physical and chemical properties of crude oil itself, during the refining process, the crude oil is subjected to high temperature, high pressure and other environmental effects to produce corrosive media, which can easily cause scaling and corrosion of equipment, which will seriously affect the performance of the refining unit. Safe operation shortens the service life of the device. In severe cases, the device may even be shut down or scrapped, which seriously affects the production efficiency and safety management of the enterprise. At the same time, this problem becomes more prominent with the deterioration of crude oil. [0003] The corrosion and fo...

[0002] Due to the complexity of the physical and chemical properties of crude oil itself, during the refining process, crude oil is subjected to high temperature, high pressure and other environmental effects to produce corrosive media, which can easily cause scaling and corrosion on equipment, which will seriously affect the performance of the refining unit. Safe operation shortens the service life of the device, and even causes the device to be shut down or scrapped in severe cases, which seriously affects the production efficiency and safety management of the enterprise. At the same time, this problem becomes more prominent with the deterioration of crude oil

[0003] The corrosion and fouling phenomenon of crude oil distillation unit mainly occurs inside the unit, which is difficult to directly observe and describe. Usually, it is necessary to conduct corrosion investigation during the maintenance period of the unit. The working time span is long, the workload is heavy, and a lot of manpower and material resources are consumed. Real-time monitoring is implemented, and the corrosion process and mechanism cannot be intuitively understood
