In view of the low desulfurization efficiency of stripper, limitation of positive pressure stripping technology and great optimization space in Yuanba gas field, a new process of negative pressure stripper desulfurization is carried out, and the influencing factors of stripper efficiency are analyzed in depth. By parameter optimization, the optimal pH value is 4.0~5.0, the recommended stripper pressure is -30~-25 kPa, the optimal gas-liquid ratio is 8~12, and the liquid inlet volume is 7~9 m 3/h, which is conducive to improving the stripper efficiency. The field application shows that the efficiency of negative pressure stripping is 96.28 %, 19.68 % higher than that of positive pressure stripping. The annual cost saving is about 1 808 600 yuan, which has significant effect on cost reduction and benefits enhancement. The new process of negative pressure stripping desulfurization shows obvious technical advantages and good application prospects, and also provides certain reference for the field application of similar marine high sulfur gas fields.
