This document describes the advantages of replacing traditional wet scrubber chemicals like chlorine dioxide, sodium hydroxide, sodium hypochlorite, and acids with alternative scrubbing agents containing amines, peroxides, surfactants, encapsulators, and deodorants. Some key benefits include cost savings of 10-50%, safer chemicals that will not freeze or burst pipes, improved hydrogen sulfide and mercaptan removal rates up to 100%, reduced insurance risks and operating costs, and a more sustainable scrubber system with extended longevity. The alternative chemicals eliminate hazards and issues associated with bulk storage and handling of caustic soda and acids.

ADVANTAGES AND BENEFITS
OF REPLACING TRADITIONAL
WET SCRUBBER CHEMICALS
SUCH AS CHLORINE DIOXIDE,
SODIUM HYDROXIDE, SODIUM
HYPOCHLORITE, AND/OR
ACIDS WITH INNOVATIVE AND
ALTERNATIVE SCRUBBANTS
CONTAINING AMINES,
PEROXIDES, SURFACTANTS,
ENCAPSULATORS, AND/OR
DEODORANTS.

2. • COST SAVINGS OF
10-50%.

3. • FLORIDA COMPANY
WITH YEARS OF
EXPERIENCE
WORKING WITH WET
SCRUBBER
CHEMICALS AND
EQUIPMENT.

4. • WINTERIZED
CHEMICALS THAT
WILL NOT FREEZE,
PLUG, OR BURST
PIPES.

5. • GREATER REMOVAL
RATES OF HYDROGEN
SULFIDE AND
MERCAPTANS FROM
90-98% AVERAGE TO
100% USING
SCRUBBANTS WHICH
CONTAIN BETTER
CHEMISTRY PLUS
SURFACTANTS.

6. • ELIMINATION OF BULK
TANKER DELIVERIES
AND BULK STORAGE
OF HAZARDOUS
CHEMICALS—LESS
FOOTPRINT.

7. Sycamore CEM
Hydrogen Sulfide Continuous Emission Monitor and
Integrated Sampling System
• IMPROVED
The Sycamore CEM is a flexible hydrogen sulfide gas monitoring system capable of
accurately measuring H2S concentrations as low as five parts per billion (5 ppb). Available INSTRUMENTATION
USING CONTINUOUS
as a one-, two-, or three-point monitoring system, it can monitor the inlet, intermediate
stage and/or outlet of odor control systems using advanced OdaLog Hydrogen Sulfide Gas
Logger technology. The OdaLog(s) provides continuous 4 to 20 mA real-time output. Each
OdaLog is coupled with its own compact, dedicated sampling system to deliver the sample
EMISSION
from a remote location to the instrument at the proper flow rate. The sampling system
removes moisture from the sample stream and automatically purges accumulated water.
An optional PID controller may be used for feedback loop control using outlet H2S gas
concentrations as the control mechanism.
