石油化工企业含有硫化氢(H_2S)的环节主要有:加氢、脱硫、废气处理、胺液闪蒸、硫磺转化等。职业性硫化氢中毒多由于设备损坏,输送管道及阀门漏气,违反操作规程,生产事故等致使硫化氢大量溢出。石油化工行业硫化氢中毒事故发生较多,造成的危害很大,若能在职业卫生评价中定量分析硫化氢泄漏的浓度及范围,可提高管理人员及作业人员对硫化氢中毒的重视程度。
Petrochemical enterprises contain hydrogen sulfide (H 2 S) of the link are: hydrogenation, desulfurization, waste gas treatment, amine flash, sulfur conversion. Occupational hydrogen sulfide poisoning and more due to equipment damage, pipeline and valve leakage, violation of operating procedures, production accidents, resulting in a large number of hydrogen sulfide overflow. The occurrence of hydrogen sulfide poisoning in the petrochemical industry is more serious, causing great harm. If quantitatively analyzing the concentration and range of hydrogen sulfide leakage in the occupational health assessment, managers and operators may increase their emphasis on hydrogen sulfide poisoning.
