Risk Assessment Techniques Of Daqing Guangming Hydrocarbon Storage Tanks

Hydrocarbon storage tank, as a main storage device of light hydrocarbon, is an important device in natural gas production, because of light hydrocarbons themselves are flammable, explosive hazard, once an accident, would result in huge casualties and property damage. To determine risk of tank farm equipment, identifying major hazards that may cause accidents, we study on the risk assessment of light hydrocarbon storage tank, development of appropriate measures, to ensure stable operation of production and reduce financial losses.The article analysis the dangerous harmful factors of storage tank, and determine the fire and explosion are the major risk factors of storage tank according to the the actual situation of Daqing Guangming hydrocarbon storage tanks and based on the detailed research on the domestic and abroad hydrocarbon storage tank risk assessment; Use DOW Chemicals fire and explosion danger index evaluation method, divided Daqing Guangming hydrocarbon storage tanks into three units, and evaluate each unit with the method. At last get fire and explosion danger level, safety measures compensating coefficient, etc.Basded on the DOW Chemicals method evaluation, detect all equipment of storage tanks with RBI, determine equipment failure probability levels from corrosion thinning, stress corrosion cracking and external damage three aspects. determine whether failure consequences level from failure after the impact of area aspects, obtains the risks of equipment from the failure probability and failure consequences combination for risk matrix and then it proposes corresponding detection strategy.Developed Daqing Guangming hydrocarbon storage tanks evaluation software according to the research of Daqing Guangming hydrocarbon storage tanks evaluation system, the software contain personal service and risk evaluation two big module, and the risk assessment module in which evaluation of a large number of theoretical calculations of the background, greatly improve the speed and accuracy of the results evaluation.
