steam vent & condensate drain during winter time
(OP)
Ice formation due to atmospheric vent of steam from Backos Pumpless Pump
Backos pumpless pumps are used at my plant for conveying steam condensate. As a design principle, atmospheric vent is required for equalizing the pressue between the condensate receiving chamber and the pumping chamber during the pressurizing circles. However, the steam from the ventline which was routed to a sump causes ice slip hazards during the cold months in the winter (environmental temperature as low as -20C). When the vent is rerouted to a underground piping to a sewer, the flash steam causes severe corrosion problem to the piping. Of course another option is to vent flash steam to a height. But I don't have experience with it. Ice formation and blockage of the 2" vent line is a concern. Your recommendation is appreciated.

If you cannot do this, you are able to use compressed air as the motive force in the pump, you will still get some flash out of the vent, but a greatly reduced amount.
