ProCeasc No sample pre-treatment No Heated Lines* Multi-Components Pre-Caiibrated No interference No Drift ProCeas® BIOGAS analyzer Complete Monitoring of Methanization O The ProCeas® Biogas is a compiete pre-caiibrated iaser infrared spectrometer of rapid reia-time measurement of H2S, CO2 and CH4 for methanization process monitoring. ' The ProCeas® Biogas uses the patented OFCEAS (WO 03031949) IR Laser technology for enhanced specificity, selectivity, accuracy and stability (no instrumental response drift.) ' The ProCeas® Biogas uses a patented low-pressure sampling system (WO 2010058107) enabling low-cost installation thank to non-heated lines* and reduced maintenance. ^ The ProCeas® Biogas is a complete, reliable, robust, low-cost and easy-to-use solution for the methanization process monitoring, including multiple sampling points throughout the entire methanizer. ProCeas® Advantages & Benefits ' DIRECT MEASUREMENT No sample pre-treatment. OFCEAS technology associated with low pressure sampling enables direct measurement. The low pressure in the sampling system removes any risk for chemicals adsorption/desorption and condensation in the line. ' NO INTERFERENCE OFCEAS technology associated with low pressure sampling provides exceptional selectivity, enabling simultaneous multi-component measurement without interferences, regardless of the matrix. ' NO RE-ZERO; NO DRIFT The zero information is contained in the signal, enabling automated and intrinsic re-zero of the analyzer. ' EASE-OF-USE The ProCeas® is pre-caiibrated for your application. Initially packaged in a standard 19”rack, it includes a touch screen interface and on-board PC for iocai / remote control and real time display / recording of results. ' EASE-OF-I The ProCeas® allows digital (Ethernet, RS485, RS232, ModBus), analog and TDR I/O’s. ' ROBUSTNESS The ProCeas® contains no optical moving parts and was designed and buiit strictly for industrial and on-board mobile applications. ' LOW MAINTENANCE High MTBF. In addition to containing no moving optical components, the IR sources (teiecom type iaser) are characterized by MTBF’s of 5 years. ' CLEAN LINES / FILTERS The iow pressure sampling system enables iow flow rates (3-9 L/h) without degrading response time. Accumuiation of contaminants iines and fitters is greatiy reduced.
