我厂润滑油生产采用酮苯脱蜡及糠醛白土精制的加工工艺。酮苯脱蜡的原理及工艺是将原料油(减压馏分油)与甲乙酮、甲苯等有机溶剂按一定比例混合,经低温处理,把原料油中的蜡析出,再经过滤、蒸发、气提等处理,制成脱蜡油送糠醛白土装置精制加工。我们发现从事酮苯脱蜡装置设备检修作业工人中发生轻度急性接触性皮炎及头痛、头晕、恶心、呕吐、乏力等不适的人数较多,但对此类人员职业危害的报告所见不多。为此,我们进行初步观察,报告如下:一、调查对象1、对炼厂各类装置设备检修钳工随机抽查66人。按其作业范围分为酮苯钳工组(酮苯脱蜡装置设备检修钳工)12人,均男
I plant lubricants used ketone benzene dewaxing and furfural clay processing technology. Ketone benzene dewaxing principle and technology is the raw material oil (vacuum distillate) and methyl ethyl ketone, toluene and other organic solvents by a certain percentage of mixing, the low temperature treatment, the crude oil wax precipitation, and then filtered, evaporated, stripping Such as processing, made of dewaxing oil furfural clay device refined processing. We found that there was a relatively large number of workers with mild acute contact dermatitis and headache, dizziness, nausea, vomiting, fatigue and other discomforts in the equipment servicing work of Ketone-based dewaxing devices, but few reports on the occupational hazards of such personnel . To this end, we conducted a preliminary observation, the report is as follows: First, the respondents 1, on the refinery equipment repair equipment fitter randomly selected 66 people. According to the scope of their work is divided into ketones clamp group (ketone benzene dewaxing equipment repair fitter) 12, both men
