Oil and gas operations in arctic climates can benefit from Munters’ new DFH mist eliminator system for protecting sensitive machinery from snow, ice and rain.
According to market communication manager Olga Krejci Halkovova, Munters has at least one Arctic reference for its mist elimination technique, for an installation offshore Sakhalin Island. The company has had very good feedback on the performance of this unit, Halkovova says. This reference installation has been shown to operate perfectly at ambient temperatures down to -36°C.
DFH builds on Munters’ DCF and DFF ranges of mist eliminators for the offshore and marine markets. These provide high-efficiency solutions to problems such as corrosion, wet filters and mold caused by moisture in the ventilation systems of rigs and vessels. As offshore operations move to increasingly harsh and cold climates, the company saw a need to develop its technology to cope with these conditions.
The system incorporates vertical profiles with a heating element. Captured snow, ice and hail particles are either melted or evaporated once they have coalesced on the heated surface. The melted particles are then drained from the eliminator through heated drainage.
The DFH system provides full protection against icing down to typical design temperatures of -36°C. Unlike competing louver designs, it can be supplied in any size, and does not cause a large pressure drop in the air flow.
An additional benefit is the control system that actuates the melting function of the separators at set parameters. The system comes with four kinds of optional sensors: thermometer, hydrometer, snow detector and rain sensor.
The units can be installed in various ways: flanged to the outside of a wall opening, with the water draining vertically down the outside of the wall; flanged into a wall opening, with the water draining into an internal tray; or in an air duct behind the weather louver, with the water draining into a tray below the air duct - a typical configuration for a retrofit.•
