目的对某加氢裂化装置职业病危害控制效果进行评价。方法依据《工作场所空气中有害物质监测的采样规范》等国家标准对该装置可能存在的职业危害进行监测和评价。结果主控制室、热油泵房、冷油泵房、压缩机厂房(一楼)的硫化氢浓度均为<0.03 mg/m3,压缩机厂房(二楼)为≤0.03 mg/m3;主控制室、冷油泵房、反应区(E1103B)的石油气浓度分别为462~663、604~663、437~604 mg/m3;主控制室、热油泵房、反应区(E1103B)的汽油浓度分别为106~129、93.3~131、107~131 mg/m3;各岗位的噪声强度为61.2~84.0 dB(A)。结论该装置有毒物质的浓度、噪声强度、工作场所的气象条件均符合国家卫生标准要求,目前的卫生防护设施是有效的。
Objective To evaluate the control effect of occupational hazards in a hydrocracking unit. Methods Based on the national standards such as “Sampling Specifications for the Monitoring of Hazardous Substances in the Workplace”, the occupational hazards that may exist in this device are monitored and evaluated. Results The concentration of hydrogen sulfide in the main control room, hot oil pump room, cold oil pump room and compressor workshop (first floor) were all less than 0.03 mg / m3 and the compressor room (second floor) was less than 0.03 mg / m3. The main control room, The petroleum gas concentrations in the cold oil pump room and the reaction zone (E1103B) are respectively 462-663, 604-663, and 437-604 mg / m3; the gasoline concentrations in the main control room, hot oil pump room and reaction zone (E1103B) 129,93.3 ~ 131,107 ~ 131 mg / m3; the noise intensity of each post was 61.2 ~ 84.0 dB (A). Conclusion The concentrations of toxicants, noise intensity and meteorological conditions in the workplace meet the requirements of national sanitary standards. The current health protection facilities are effective.
