S气体逸出
对周围环境影响严重
为此提出了采用氧化铁吸附脱除原油挥发气中H

S的固定床脱硫反应器建立了数学模型
利用COMSOL软件进行了求解
模拟计算出不同条件下固定床脱硫反应器的穿透曲线
并与实验值进行了对照
同时进一步探讨了吸附容量的影响因素.研究结果表明:采用的氧化铁脱硫剂在空速为1 500 h
-1
至4 200 h
-1

穿透硫容随着空速的降低而增加; 空速再度下降会导致穿透硫容减小; 穿透时间和穿透硫容随温度的升高而增大.另外
在相同空速下

Hydrogen sulfide gas could escape from storage tank area in the process of crude oil storage and transportation
which can pollute the surrounding environment. According to the characteristics of crude oil tank area
a process with fixed bed reactors for removing volatile gas H
2
S from the crude oil by ferric oxide was proposed in this study. In order to understand the desulfurization process
a mathematical model of the fixed bed desulfurization reactor was established and the simulation was performed by using the COMSOL software. The simulation result shows that the breakthrough curves under different conditions are in reasonable agreement with the experimental data. Moreover
the investigation into the effect on the adsorption capacity indicates that the breakthrough capacity of the ferric oxide desulfuriz
ing agent increases with the decrease of the space velocity in the range from 1 500 h
-1
to 4 200 h
-1
. If the space velocity decreases further
the breakthrough capacity decreases. The breakthrough time and capacity increase with the increase of the temperature. In addition
the variation of the input H
2
S concentration changes the breakthrough time
but it has no influence on the variation of sulfur capacity under the same space velocity condition.
