this month's topic Environmental EquipmentFluidized-Bed System Scrubs Emissions
RotaBed fluidized-bed gas-cleaning technology controls pulp bleach plant emissions by removing fugitive chlorine and chlorine dioxide, which are created during pulp bleaching. The system creates a fluidized gas/liquid mixture to clean 15,000,000 ft3/h of contaminated air at or below all mandated compliance levels. This advanced technology is widely used for gas absorption and cleaning where other designs may plug. It is designed for clean-in-place (CIP) operation to maximize performance with minimal downtime. Despite its compact size, it operates at a gas velocity more than double that of a larger packed tower, yet it has a pressure drop of less than 10 in.

Air-Monitoring System Detects Many Types of Contaminants
The open-path Fourier transform infrared (FTIR) air-monitoring system simultaneously detects, identifies and measures a wide range of contaminants at levels from percent to parts per billion. Each system includes an interferometer that is equipped with user-selected beamsplitters and detectors. The analyzer is coupled to a control PC via standard ribbon cable or long-range fiber optic link. A continuous sampling path up to 1,000 m long is standard; for extended sample paths, the FTIR can be mounted to a rugged 10-in. Newtonian telescope supported by a tripod. A high-energy infrared source module on the opposite end of the sample path completes the system. Weighing 40 lb and measuring 8 in. W × 14 in. D × 8 in. H, the compact interferometer module is easy to transport and can be powered by a 12-V car battery. An optional lightweight sheetmetal version of the FTIR is available with a compact 3-in. telescope. The system is suitable for industrial stack monitoring, fenceline monitoring, hazardous event response, analysis of chemical warfare agents on the battlefield, and environmental research (such as volcanic gas analysis).

Device Wirelessly Monitors Many Environmental Parameters
The PPMonitor continuously detects, measures and records a variety of parameters, including temperature, humidity, formaldehyde, nitrogen dioxide, carbon monoxide, carbon dioxide, sulfur dioxide, ozone, ammonia and total volatile organic compounds (VOCs). The monitor’s real-time functions provide immediate warnings of the presence of harmful gases in the air. It communicates via the Zigbee wireless mesh network, which can be extended easily by adding repeater nodes or additional PPMonitor units. Custom sensor specifications allow a greater level of monitoring across the entire building or complex, which results in a more detailed representation of indoor air quality in general. Other advanced industrial-hygiene functions can be automatically calculated and used to trigger alarms. The monitor’s software generates statistical data and reports, and enables the data to be viewed graphically.

Gas Cylinder Protects Environmental Equipment
The ECOCYL OSQ specialty gas cylinder uses negative gas pressure to protect sensitive environmental monitoring devices. Such instruments are susceptible to damage from the positive gas pressure often associated with conventional cylinders. This specialty gas cylinder has an integrated cylinder valve and pressure regulator, and its flow control valve is covered by a protective cowling, which makes it safer and easier to handle than cylinders requiring gas-handling equipment. The cylinder is suitable for detection monitors with integrated pumps, as well as for monitors that are calibrated in docking stations with built-in pumping devices.
