Procal - Parker Hannifin Corp
Procal 5000 is an ultra-violet (UV), continuous emission monitoring analyser, designed for in situ analysis of gas-phase emission components. Using absorption spectroscopy, Procal 5000 stores and analyses the full UV spectrum and calculates the gas emission concentrations. A typical system comprises an in situ analyser, an integral calibration function and a Control Unit. Procal 5000 uses the reflective beam principle to directly measure process gas as it enters the in situ sample cell. Unlike higher maintenance extractive systems, Procal’s patented, sintered metal technology removes the need for gas filtering or sample conditioning. Maintenance is minimised by an integral zero and calibration point gas capability and frequent calibration checks which can be undertaken without intervention, enabling automated legislative compliance.
The Procal 5000 analyser uses a single beam of UV light from a long-life deuterium arc lamp. The beam is split and directed into a folded beam cell assembly before returning to fall on to a 1024 bit diode receiver array. A narrow region of the spectrum is measured by each diode and the spectrum is logged as a vector intensity enabling gas concentrations to be calculated. Up to six gas-phase component concentrations can be monitored simultaneously. Uniquely, the operation, zeroing and calibration are “fully challenged” in that all operating modes use the same optical path and system components. Applications:
The Procal 5000 analyser has been in service for over 15 years with continual product improvement to match ever-tightening legislative requirements.
Optional accessories are available to extend the analyser’s capability in cases of extreme process or ambient variations. Typical examples would be a probe heater to ensure the in situ gas cell operates above process gas dew point, a gas flow bypass for high thermal stress applications and a head cooler for operation in high ambient temperature conditions.
Analyser Control Unit - Procal 1000 series
The Procal 1000 data logging and control system can be either supplied as software only or installed in an IP65 control unit. The system is capable of controlling up to six, widely dispersed, Procal analysers of any design. The Procal 1000 series is also designed to accept signal I/O from other instruments in the process to provide a single CEMS data hub.The Procal 1000 system displays gas concentrations and third party analyser I/O along with information on sample conditions, diagnostic data and trends. The information can also be made available to external systems in a variety of industry standard data protocols.
Chemical Industry Emissions Analysis - Chemical & Pharmaceuticals
The inherent flexibility of Procal analysers enables the instruments to be configured to meet Customer’s specific requirements. Their capability to monitor gas concentrations at elevated pressures and temperatures make Procal products ideal for process applications in the Chemical Industry.
Incineration Industry Emissions Monitoring & Analysis - Waste and Recycling - Waste to Energy
Monitoring of emissions from incinerators is a demanding application for Continuous Emission Monitoring Systems. The emissions produced are highly corrosive, some of the gases are soluble and, because the waste being burnt is constantly changing, the resulting stack gas temperature varies widely.
