Embodiment 1

[0012] like figure 1 As shown, firstly, the corrosion circuit of the device is divided, and the corresponding mathematical model is established according to the respective corrosion mechanism, the corrosion risk assessment is carried out, and the corrosion risk is quantified. The high-temperature corrosion risk of the device basically depends on the contradiction between the material and the degree of deterioration of the raw material oil. According to the results of the corrosion assessment, it is judged whether the material of the device is basically compatible with the degree of deterioration of the processed raw oil. If the established acceptable risk standard cannot be reached through partial material upgrade, the corrosive medium will be fortified to limit the content of corrosive medium in the feedstock oil of the unit until the high temperature corrosion risk can meet the established acceptable standard after local material upgrade. Then, according to the corrosion ris...

Abstract

The invention relates to a risk-based oil refining device corrosion management control method. The objective of the invention is mainly to solve the problems of unscientific and unreasonable anti-corrosion resource allocation and lack of control on corrosion intermediate process and difficult continuous improvement. The risk-based oil refining device corrosion management control method of the invention comprises the following steps that: (1) corrosion loop division is performed on a device, and corresponding mathematical models are established according to respective corrosion mechanisms, and corrosion risk assessment is performed; (2) according to the results of the corrosion risk assessment, reasonable material anticorrosion, process anticorrosion and corrosion monitoring detection measures are taken; (3) the control on the corrosion intermediate process is strengthened through relevant theoretical model calculation; (4) on the basis of the results of the corrosion risk assessment, reasonable repair schemes are formulated; and (5) results are fed back to the process of the corrosion risk assessment, and the PDCA cycle of a whole corrosion management control scheme is established. With the above technical schemes adopted, the above problems can be effectively solved. The risk-based oil refining device corrosion management control method can be applicable to oil refining device management corrosion management control.

Description

technical field [0001] The invention relates to a risk-based corrosion management and control method for an oil refinery unit. technical background [0002] As the trend of crude oil deterioration continues to intensify, the content of corrosive substances such as sulfur and acid in crude oil continues to increase, which brings more and more serious corrosion problems to refinery units. How to ensure the safe operation of oil refining equipment and improve the intrinsic safety level of the equipment is a reality that my country's refining and chemical enterprises must face seriously. How to ensure long-term stable operation of the unit and keep the corrosion risk of the equipment under control is an urgent problem that oil refining units are currently facing. This is as much a management issue as a technical one. [0003] CN201210536069.7 provides a comprehensive corrosion management system for offshore oil and gas fields, which is composed of management personnel function...
