Aiming at the high concentrations of methanol sewage corrosion Present Situation for a natural gas processing plant in the Sulige gas field, oilfield oxygen scavenger is developed indoor. Through site visits, laboratory experiments and theoretical analysis, the treatment process increases the oxygen scavenger dosing port, and scale inhibitor dosing mouth to feed from the filter after the previous the reaction settling tank. The test results show that good stability of the technique, oilfield deoxidant site dosage is 0.1%, the antiscalant dosing concentration is 130mg/L, the corrosion rate of the dosing outlet of the filter lowers to 0.038mm/a after 25 days, the scaling phenomenon does not appear in the 75°C. Methanol recycling equipment corrosion and scaling problems are resolved, which gives a good protection to the entire system.
