As the profitability of refineries improves, the selection of crude oil has diversified and inexpensive crude oil containing mercury is increasingly being processed. Currently, more than 20 mercury removal plant are in operation in Japan, but the operating conditions for implementation vary widely in temperature, pressure, flow rate, etc. and the timing for replacing the mercury removal material is often different from the theoretical one. In this report was described the method used to find out when to replace the mercury removal material in the mercury removal plant in operation, based on a large amount of operational data and theoretical values of the mercury removal material in the laboratory.
