| Crude oil tank is a major hazardous source. Disaster accident will take place if it is destroyed. Study on safety assessment of crude oil tank and alteration of key technology of it is carried out in this paper, which has great significance for improving the safety of crude oil tanks, thus preventing disaster accident protecting people's life and property.According to the characteristics of crude oil tanks and based on the analysis of lots of safety assessment methods, the safety assessment methods such as Dow fire&exploding hazardous exponent method, accident trees method, tank leakage modal was selected for safety analysis and assessment for the hazards of fire, explodeing and leakage of crude oil and corresponding safety measurement was proposed. In the fact engineering, manual valves are usually used in the crude oil tanks, which may be wrong operated. To solve the problem, the alteration of automatization control system for manual valve, which includs adding automatization devices such as pneumatic head, PLC control system, industry Ethernet, was carried out. Thus, the automatization level of the crude oil tant farm is improved and the intensity of labour is decreased, which insure security of operation of crude oil tank farm. |
