Studay On Hydrogen Sulfide Poisoning Risk Identification And Classification Methods During High Sulphur Crude Oil Processing Process

As the world’s crude oil resources drying up, the high quality crude oil quantity is lessand less, the quantity of domestic imports of inferior crude oil also will increase. In order toimprove the economic benefit, reduce the processing cost, many Domestic refineries alsobegan to process inferior crude oil, especially for high sulfur crude oil processing capacityincrease year by year. This not only presents a challenge to practice equipment, also directlyaffect the safety of operating personnel. In order to improve the reliability of refineryprocessing high sulfur crude oil, and reduce the risk of workers poisoning, In this paper, basedon the research result of sulfur migration transformation rule, selective analysis Hydrogensulfide sources, distribution and harm, Identify the risk leakage point of Hydrogen sulfide,take Qingdao refinery as an example, Identify Hydrogen sulfide distribution in typicalrefining device. In order to management hydrogen sulfide leakage effectively by refineryplant, Using the event tree analysis to seek the reason lead to hydrogen sulfide leakage factors,Combining with the refinery process, draw up systematic approach to look up Hydrogensulfide leaks point.Put forward a set of effective hydrogen sulfide poisoning risk classification method toaim at hydrogen sulfide leakage point, The method is based on hydrogen sulfide leakageprobability and consequences, use Analytic hierarchy process to make risk grading, In orderto manage hydrogen sulfide poisoning effectively by the enterprise which processing highsulphur crude oil, Combined with the classification results, using VB programming languageto develop a set of stand-alone version management software.To effectively monitor for hydrogen sulfide leakage, Establish a set of on-linemonitoring system for hydrogen sulfide, According to the early research of Qingdao refineryand exploration, Introduce the arrangement of hydrogen sulfide monitor,and the amount ofOnline monitor in different hazardous area and arrangement principles. Put forward differentspecific measures of poisoning prevention for processing high sulfur crude oil refineryoperators in different nature of work, set new protection standards for different operators toensure that workers in daily operation can effectively prevent the harm of hydrogen sulfide. In addition, put forward the hydrogen sulfide leakage specific protective measures including howto deal with poisoning personnel.
