组合式负压闪蒸罐脱硫化氢方法

On the Hydrogen Sulfide Removal Method of the Combined Vacuum Flash Tank

为降低物流中的硫化氢的浓度,在源头控制硫化氢污染腐蚀,免于下游管线及设备的腐蚀危险,采用负压闪蒸法脱除物流中的硫化氢气体,创新应用组合式负压闪蒸罐,以达到高效脱除硫化氢和减少设备占地面积的目的;敏感性分析表明,影响负压闪蒸脱硫化氢方法的重要影响因素为硫化氢浓度和物流温度及负压闪蒸的压力选择。

In order to reduce the concentration of hydrogen sulfide in the stream, control hydrogen sulfide pollution corrosion at the source, avoid the corrosion hazard of downstream piping and equipment, the method of vacuum flash is used to remove the hydrogen sulfide gas in the stream. The combined vacuum flash tank is applied to achieve efficient removal of hydrogen sulfide and reducing equipment footprint. The sensitivity analysis show that the important factors impacting negative flash removal method of hydrogen sulfide are the hydrogen sulfide concentration, the stream temperature and the negative pressure selection flashed.
