WHAT IS A CHLORINATED ORGANIC?
Compounds that contain
– Carbon, Hydrogen and Chlorine Atoms
Examples
– Dioxins
– PCBs
– Carbon Tetrachloride
– Vinyl Chloride
– Chloroprene
MACT EMISSIONS CONTROL
Flare
– Halogenated vent streams can’t be flared
– Corrosion, acid formation
Incinerator/Boilers
– Need a scrubber
Condenser
– Cooling Media
– Recovery Device
– Save Money
TUBE HEAT EXCHANGER
MONITORING REQUIREMENTS
Under the MACT (MON, HON, P&R, etc.)
– Group 1 and Group 2 Vents
Group 1 – 98% reduction
Group 2 – maintain TRE 1 to 4
– Use recovery device
– Continuous monitoring of specific parameters
TRACKED PARAMETERS
Inlet temperature of brine
Valve position on the brine lines (open/closed)
Discharge pressure of brine pump
Check on visible emissions
SUMMARY
Condensers
Monitoring Alternatives
