Refinery device operation cycle expert decision-making system and method based on reliability analysis

Abstract

The invention belongs to the field of petroleum chemical industry and discloses a refinery device operation cycle expert decision-making system and method based on reliability analysis. According to the decision-making method, based on function, function fault, fault mode and fault result analysis of a refinery device, the probability statistics is applied to obtain the safety and reliability dataof the refinery device, and a refinery device system analysis platform is established; the states of each system, equipment and part of the refinery device are judged, and a scheme with the need of preventative maintenance, regular maintenance, improvement or redesign is determined; and equipment maintenance, inspection, an inspection cycle and means are determined further, and finally a practical, reasonable and scientific maintenance plan or maintenance program or maintenance strategy package is made. Through establishing a data information analysis platform of equipment basic data and maintenance data, a refinery device long cycle data analysis model is constructed, and a long cycle dynamic maintenance strategy task package suitable for the device is formed.

Description

technical field [0001] The invention belongs to the technical field of petrochemical industry, and in particular relates to an expert decision-making system and method for the operation period of refining and chemical equipment based on reliability analysis. Background technique [0002] With the increasing complexity of equipment, a large number of preventive maintenance, short maintenance cycle and deep maintenance depth often cause the maintenance cost to be overwhelmed, and the failure rate has not been effectively controlled. Reliability analysis methods emerged as the times require, and have been widely used in aviation and military fields. In recent years, the nuclear power industry has also developed. This method has also been tried in petrochemical and other process industries. However, due to the complex operating conditions of petrochemical equipment, the operating environments and parameters of equipment and components are different, and their failure modes are a...

Problems solved by technology

[0004] The existing technology research in this field is somewhat one-sided, and often focuses on the research of a certain failure mode of a certain equipment or a certain system, and lacks the research on the interaction between equipment, systems, and failure modes, that is, it has not reached a specific system. Therefore, unexpected equipment failures still occur from time to time. In order to avoid this situation, measures such as frequent preventive maintenance and increasing the frequency of parts replacement have been adopted, resulting in higher maintenance costs.
