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

Electronic Records
