Abstract
A process is provided where a waste stream is directed to an evaporator that produces a vapor having volatile compounds. The vapor including the volatile compounds is directed through a vapor scrubber that contacts the volatile compounds with a scratching solution. The scrubbing solution reacts with the gaseous volatile compounds in the vapor such that the volatile compounds pass from a vapor state into the scrubbing solution and form volatile compounds in the liquid scrubbing solution. The scrubbing solution is collected and recycled.
Claims17
A method of treating a waste stream having volatile compounds contained therein, the method comprising:
- directing the waste stream to an evaporator;
- evaporating water and volatile compounds from the waste stream in the evaporator to form vapor which contains gaseous volatile compounds and a concentrated brine;
- directing the vapor having the gaseous volatile compounds to a vapor scrubber;
- contacting the vapor having the gaseous volatile compounds with a reactive scrubbing solution as the vapor passes through the vapor scrubber;
- reacting the scrubbing solution with the gaseous volatile compounds such that the gaseous volatile compounds pass from the vapor into the reactive scrubbing solution and form liquid volatile compounds in the scrubbing solution, wherein reacting the scrubbing solution with the gaseous volatile compounds produces a treated vapor stream;
- and
- collecting the scrubbing solution having the liquid volatile compounds removed from the vapor.
