I would be looking at a way of either re-introducing the condensed steam back to the boiler, or using a heat exchanger to pre-heat your boiler feed water with the 'contaminated' steam exhaust.
If you do go the second route it will be much easier to seperate the contaminents from the condensate when it is back to ambient temperature.
This would save your company lots of $$$$ over a year, as well as doing your bit for the environment
