The report gives results of an investigation of the use of the PuraSiv Hg adsorption process to remove mercury from the hydrogen byproduct stream and the end-box ventilation stream from mercury cell chlor-alkali plants. The investigation included the analysis of data obtained from testing of a system that is currently in operation and technical information provided by the system vendor together with that available in the open literature. Although the measurements of mercury concentration in the hydrogen byproduct stream entering the PuraSiv Hg adsorber, taken during performance testing of the control unit, appear to be in error, measurements of the outlet concentration indicate that a concentration less than 60 ppbv may be achieved. The economics of the PuraSiv Hg adsorption process were explored. Available data indicate that the operating costs by this process vary between $0.58 and $0.33 per ton of chlorine produced for plants with capacities between 100 and 750 tons per day. Mercury may also be removed from the hydrogen byproduct stream either by brine adsorption over treated activated carbon or by scrubbing with depleted brine. Technical and economic data available to the investigator seem to favor the use of these two processes for mercury control, although the data base thereon is not sufficiently developed to warrant a meaningful comparison.
