The Baldwin™-Series Acid Safety Scrubber (Part No. 3SCR-004) helps protect your analyzers from corrosion due to acidic gas stream components, especially hydrochloric acid and sulfuric acid. The Acid Safety Scrubber is recommended for coal-fired boiler, waste incinerator, and other applications where acidic gases are common. The Acid Safety Scrubber consists of a threaded borosilicate glass tube with end caps, calcium carbonate scrubber material, elbow fittings, and mounting clips. The scrubber material should be replaced on a periodic basis (usually every 1-3 months) based on acid concentration in the gas stream. An acid safety scrubber refill kit is available (Part No. 3KMC-001). Approximate Acid Safety Scrubber dimensions: 12 inches x 1.5 inches diameter. The unit should be installed after a Baldwin Thermo-Electric Cooler. Acid Scrubber |

Specifically Designed to Remove SO3 Aerosol The Perma Pure Baldwin-Series Aerosol removal system is specifically designed for gas sample applications with relatively high SO3 content (>10ppm). The SO3 aerosol removal series has special timing circuits that alternate freeze and thaw the precisely packed heat exchangers. Before an active heat exchanger thaws, the alternate active heat exchanger reaches the -7C set point to ensure uninterrupted operation and no SO3 slippage. This sub zero temperature forms a thin ice layer that captures and removes SO3 aerosol from the sample stream. Operation The two heat exchangers located on the left side of the sample cooler are connected in series. The sample stream first passes through an inactive exchanger used for removing gross amounts of water. The sample then passes to an active glass heat exchanger. The exit dew point from this heat exchanger is controlled to +4°C, thereby reducing he moisture concentration to less than 1%. The gas sample then flows through the gas sample pump where it alternately passes through frozen Kynar® packed heat exchangers, located on the right side of the cooler, then to three-way Teflon® solenoid control valve and finally to the remainder gas sampling system. Condensate is pumped from each heat exchanger by a dedicated peristaltic drain pump head. SO3 Model 545 & 10410 SO3 Model 10410 Manual |

SDS™ -Series Supplemental Drying Systems from Perma Pure provide a boost to an existing gas sample conditioning system. The SDS will reduce the dew point of the sample from +4°C down below -15°C, reducing the total moisture content by an additional 80%. Reducing the gas sample dew point is essential in order to eliminate the formation of acid mists. Rather than replace an existing cooler with a “super” cooler, the SDS is a cost effective way of extending the life and improving the performance of your existing sample conditioning system. Infrared analysis of CO and SO2 is very susceptible to moisture interference, as are measurements of low ppm concentrations of NOx and H2S. It is desirable to remove as much moisture as possible. In these applications, installing the SDS downstream of your conditioning system is an effective and less expensive alternative to a complex subzero cooler. SDS |
