以塔河12区含硫原油为研究对象,通过模拟铁路运输原油工况,研究罐内原油中H2S挥发规律。结果表明,铁路运输过程中原油里H_2S析出浓度与时间的关系近似为6次多项式,并建立了H_2S浓度随时间变化的曲线方程;对影响罐内原油中H_2S挥发的2个主要因素罐内原油温度和罐车振动强度进行了分析。结果表明,罐内原油温度是原油中H2S挥发的主要影响因素,升高罐内原油温度可以明显增加H2S的挥发浓度,加大罐车振动强度对原油中H_2S挥发有促进作用,但不明显。
Taking Tahe12 area sulfur-bearing crude oil as the research object, the law of H2S volatilization in crude oil was studied by simulating the condition of crude oil transported by rail. The results show that the relationship between H 2 S concentration and time in crude oil during railway transportation is approximately 6th order polynomial, and the curve equation of concentration of H 2 S with time is established. Two main factors that affect the volatilization of H_2S in tank oil are: Temperature and tanker vibration intensity were analyzed. The results show that the crude oil temperature in the tank is the main influencing factor of H2S volatilization in the crude oil. Increasing the temperature of crude oil in the tank can obviously increase the volatile concentration of H2S. Increasing the vibration intensity of tanker can promote the volatilization of H2S in crude oil, but not obvious.
