原油掺混脱硫剂过程中的热危险性

Thermal Hazard During Crude Oil Desulfurization Processing

采用C80微量量热仪研究了原油以及2种典型脱硫剂TS02和JH02与原油掺混物的热分解特性,在此基础上分别计算了活化能、指前因子等反应动力学参数,对比分析了2种脱硫剂对原油热分解过程的影响规律。结果表明,原油在掺混脱硫的过程中,起始分解温度和反应活化能均有所降低,反应放热量增大,自加速分解温度(SADT)变低,原油和脱硫剂掺混物的热危险性远大于纯原油,并且JH02脱硫剂对原油脱硫过程的影响大于TS02脱硫剂。

Thermal decomposition behaviors of crude oil and its mixtures with two kinds of typical desulfurization agents, named as TS02 and JH02, were studied by C80 micro-calorimetry. Based on the acquired data, reaction kinetic parameters such as activation energy, pre-exponential factor, etc, were calculated, respectively, and then the influences of two desulfurization agents on thermal decomposition of crude oil were analyzed and compared. The results showed that the initial decomposition temperature and the decomposition activation energy of the crude oil were reduced by mixing crude oil with desulfurization agent, at the same time, the heat of decomposition reaction increased and the self-accelerating decomposition temperature（SADT） decreased. Thermal hazard caused by the mixture of crude oil with desulfurization agent was far higher than that by pure crude oil. The JH02 had much more influence on crude oil desulfurization process than TS02.
