Components
Acid Injection (optional)
This equipment optimizes the reduction of SO2 loss during cooling/drying process of the sample gas. SO2
solubility errors become more reproducible and measurement equipment can be better calibrated. By
injecting dosed amounts of an acid (e.g. H2PO4 or H2SO4, 5%) or of an aqueous solution of salt (e.g.
NaHSO4 or KHSO4, 10%) in the gas flow, you can raise the PH value of the forming condensate so high,
that the solubility of SO2 decreases. The equipment can also be used for washing alkaline gases (e.g.
NH3 or NH4Cl).
The acid/solution is continuously injected by a peristaltic pump. The pump operates continuously, but can
also be controlled externally (option). Different pump hoses allow following dosages: N1,6x1,6mm -
12ml/h, N3,2x1,6mm - 42ml/h. Before entering the heat-exchanger, acid and gas are thoroughly mixed
in a swirl line.
FEATURES AI
 Reduction of SO2 loss
 Washing of alkaline gases
 Acid dosage by peristaltic pump
 Dosage: 12ml/h or 42ml/h
 Injection with swirl line
Sample Gas Pump (optional)
Into the cooler integrated sample gas pumps transport continuously and reliably the sample gas through
the whole system. There are several pump model types available, optimized for different applications. All
pumps operate oil-free and ensure a straight and uncontaminated transport of the gas. You can exactly
dose and monitor the performance of the pump respectively the gas flow rate by an integrated flowmeter
(option). Possible discontinuities in the gas flow can be monitored by a light barrier (option). Please
notice the attached product information and technical data of the pumps.
The sample gas pumps start automatically after reaching the cooling temperature. At temperature alarms
or alarms triggered by moisture sensors the pumps are automatically stopped. Due to this feature your
subsequent analyzers are optimally protected.
FEATURES SAMPLE GAS PUMPS
 Uncontaminated flow
 Chemically resistant, maintenance-free
 Application-optimized model types
 Start/Stop-automatic
 Perfect integration into the cooler
