Aggravated corrosion conditions caused by H2S in mixture of oil, brine and gas are responsible for some of the highest equipment failure rates in the petroleum industry. Thw sulfide scavengers HP1 and HP2 have been developed to protect well equipment and pipeline steel from sulfite cracking, electrochemical corrosion and corrosion fatigue. The desulfurisation efficiency and corrosion inhibition rate of scavengers in multiphase systems were measured in the laboratory. Their desulfurisation efficiency exceeded 90% and the corrosion inhibition rate was up to 98%.

Based on the obtained results, the scavengers HP1 and HP2 can be recommended for field test and field application as well.
