Liquid Ammonia Long Distance Pipeline Leakage Risk Analysis And Countermeasures

Throughout long-distance pipeline years of development, pipe accidents occurre d frequently cause social of pipeline security concerns. And liquid ammonia pipelines as liquid ammonia transport of a new mode of transportation, let everybody knows to that it has superiority over, it is also let people to its security questioned. Because at p resent China's chemical long-distance pipeline construction is still in the initial stage, various regulations still is in blank phase, and its relevant studies less. So carrying out of liquid ammonia long-distance pipeline leakage risk studies has important signifyca-nce to enhance our country's liquid ammonia long-distance pipeline security supervisi on level and China chemicals long-distance pipeline development.This paper liquid ammonia long-distance pipeline leakage risk investigated and analy zed. Of our country at first long distance pipeline security situation are summarized. T hen in the field investigation and based on the analysis of the accident, use to cause le akage accident tree analysis of the cause of the accident incident has qualitative analy sis, ask out of minimum cut set, identify causes pipe leakage main influence fact ors, which can provide for pipeline risk management experience and reference basis. Then in the accident tree analysis risk factors combined with the actual situation of pipe as score content, in Kent pipeline evaluation method to a liquid ammonia pipe lines, anal ysis of the risk assessment in risk factors, under the action of different modeled for protective measures of different and environment caused by the different between diff erent pipeline leakage risk. Through the above analysis, we can draw the whole pipeli ne leak greatest risk, the medium and small, which can be modeled on leakage risk is big modeled on special protection, will leak risk to the minimum. Finally, according to the above analysis puts forward related suggestions and measures.
