Crude oil storage leakage monitoring and early warning system based on oil film detection sensors

Abstract

The invention relates to a crude oil storage leakage monitoring and early warning system based on oil film detection sensors.The crude oil storage leakage monitoring and early warning system comprises a monitoring center, and the monitoring center is connected with a first monitoring unit, a second monitoring unit, ..., an n-th monitoring unit.The oil film detection sensors are arranged at crude oil leakage high-risk sites such as a tank field fire dike water outlet, a tank top center drain pipe outlet, the periphery of a crude oil pump, the peripheries of a crude oil pipeline valve and a flange and the front of a plant area rain outlet to form a leakage monitoring network, oil overflow is monitored in real time, and timely finding, warning and preliminary control at an initial leakage stage are guaranteed.The oil overflow can be monitored in real time, and timely finding, warning and preliminary control at the initial leakage stage are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of oil depot safety monitoring and early warning, and in particular relates to a crude oil depot leakage monitoring and early warning system based on an oil film detection sensor. Background technique [0002] In recent years, with the development of large-scale external floating-roof tank technology, the number of large-scale external floating-roof tanks in crude oil storage tanks and oil reserve depots of petrochemical enterprises has increased year by year, and the capacity of a single tank has also become larger and larger (generally 100,000 m 3 ). It has the advantages of less oil loss in payment and storage, less environmental pollution and convenient operation. However, once a leak occurs in the crude oil storage area, it may cause more serious safety accidents such as fire and explosion. If the leak leaves the factory, it may cause serious environmental pollution accidents. Therefore, early warning...

AI Technical Summary

Problems solved by technology

Due to the low saturated vapor pressure of crude oil, low volatility, and being in an open-air environment, a small amount of volatiles in the early stage of leakage is difficult to reach the lower alarm limit of the combustible gas alarm device, so it is difficult to detect the accident in time at the early stage; the coverage of video surveillance is limited, The role of monitoring equipment is limited at night and when visibility is low, and automatic alarms are generally not available when oil spills occur; the effect of manual inspections will be affected by inspection frequency, inspection routes, weather visibility, operator responsibility, etc.
