摘要
根据涠洲11-1油田混输原油含硫化氢情况,针对海上采油平台空间受限、海管混输流体组成特点以及腐蚀性因素,采用超重力脱硫装置协同配套药剂进行了超重力海管混输原油多相流体脱硫化氢现场工业试验。试验结果表明:超重力脱硫设备能够有效地脱除多相流体中的游离气体;超重力脱硫设备协同GLT-203硫化氢清除剂可以将多相流体中的硫化氢浓度降至20 mg/m^3以下;提高超重力机转子转速有利于强化传质,增强药剂的脱硫效果;原油温度升高更有利于旋转填料床将液相分散为更细小的液滴,大大降低硫化氢的传质阻力,加速药剂同硫化氢的反应速率。
According to mixed transportation crude oil containing hydrogen sulfide in Weizhou 11-1Oilfield, in view of the limited space for offshore oil platform, subsea pipeline mixed transmission fluid composition characteristics and key corrosive factors, using the gravity desulfurization device together with a complete set of reagents, field industrial testing on the gravity subsea pipeline mixed transportation crude oil multiphase flow hydrogen sulfide removal. The experimental results showed that： super gravity device can effectively removing the free gas in multiphase flow, super gravity desulfurization equipment cooperate with GLT- 203 hydrogen sulfide scavenger makes mu[tiphase fluid levels of hydrogen sulphide can be lowered to below 20 mg/m3; super gravity machine rotor speed increase is beneficial to strengthen mass transfer, enhance the desulfurization effect of drugs; oil temperature is more advantageous to rotating packed bed spread liquid for more tiny droplets, greatly reduces the mass transfer resistance of hydrogen sulfide, accelerated the reaction rate of reagents with hydrogen sulfide.
