Improving Techniques Process of Mercury Removed in Yakela Gas Condensate Treating Station

Little mercury in gas induced a strong corrosion for plate-fin heat exchanger (cool box for short) made of Aluminum alloy, which was used as light hydrocarbon device. Gas escaped even production was stopped because of the pitting-corrosion, which caused great financial losses but also security risk unless we remove mercury immediately. This paper introduced the corrosion caused by mercury in Yakela gas condensate treating station (Station Ya for shot), and then authentication of mercury removing technology carried out after the process of dehydration by molecular sieve, which reduced mercury value to 0.01μg/m³ with activated carbon impregnated with sulfur, presenting a useful effort for safe and secure routine production.
