A cathodic protection automatic monitoring system for petroleum storage tanks

Abstract

The invention provides a cathodic protection automatic monitoring system of a petroleum storage tank, belongs to the technical field of petroleum chemical engineering, and solves the problem of shortage of effective methods for accurately detecting a cathodic protection system of the petroleum storage tank in real time in the prior art. The cathodic protection automatic monitoring system of the petroleum storage tank comprises multiple auxiliary anodes, multiple reference electrodes, a voltmeter, a potentiostat, a control module and an upper computer; all the auxiliary anodes are electrically connected with a positive pole of the potentiostat; a tank body is electrically connected with a negative pole of the potentistat; each reference electrode is connected with the tank body through the voltmeter; the voltmeter is connected with the control module; and the control module is connected with the upper computer. The cathodic protection automatic monitoring system of the petroleum storage tank has such advantages as detection timeliness, accuracy and reliability.

Description

technical field [0001] The invention belongs to the technical field of petrochemical industry and relates to a cathodic protection automatic monitoring system for petroleum storage tanks. Background technique [0002] Storage tanks are one of the important equipment for oil depots, ports and petrochemical enterprises to store liquid raw materials and intermediate products, and are essential equipment for crude oil storage projects. With the rapid development of the petrochemical industry and the country's huge demand for energy, a large number of steel storage tanks have been established throughout our country. These storage tanks suffer from corrosion problems from internal and external environmental media during operation and use, which has an important impact on the safe operation of storage tanks. With the full development of the crude oil storage project, the research on the corrosion protection of storage tank equipment has become one of the hot spots in the industry,...

Problems solved by technology

[0004] At present, the detection of cathodic protection potential adopts manual regular monitoring, and the appropriate monitoring period is one month. If the monitoring period is too long, it is difficult to ensure the effectiveness of cathodic protection. If the monitoring time is too short, the monitoring cost will increase sharply, which will greatly increase the maintenance cost of the pipeline.

The evaluation of manual monitoring results is mainly based on experience, and its rationality and accuracy are obviously insufficient, and it is not timely, unsafe, and difficult to evaluate
