    Continuous emissions monitoring for glass manufacturing

    Process control and emissions monitoring in a glass manufacturing plant is a challenge due to high temperature in the flue gas. The OPSIS DOAS system provides the glass industry with an accurate analyser that will operate with a minimum of maintenance. The OPSIS DOAS system is based on a non-contact method that uses an optical path to measure across the duct.

    Gas analysis & monitoring system for gas generation

    The gas generators for calibration based on the use of “Method of Permeation Tubes.”. The permeation tubes are sealed capsules containing a small amount of the component that is in contact with a permeable membrane stable. The permeation through the membrane produces a vapor of the compound of the component of small quantity, very stable as a stream in time. This permeate stream by mixing with a dilution gas controlled and precise (for example nitrogen) creates a mixture in track at the desired concentration. The flow of the permeate is measured metrically through severe weight loss of the tube thus ensuring a standard high precision.

    Raw-gas monitoring for scrubber optimizing

    The consumption of scrubbing material in a scrubber is related to the mass flow of acid gases. Hydrogen chloride (HCl) and sulphur dioxide (SO2) are the major acid gases in an incinerator. By measuring the mass flow of SO2 and HCl in the raw gas going into the scrubber, it is possible to calculate the required quantity of scrubbing material.

    Measurement of methane and non-methane hydrocarbons for environmental air quality.

    The Model 8900 Methane/Non-Methane Analyzer provides direct measurement of Methane and Non-Methane Hydrocarbons. This instrument is utilized in ambient air monitoring networks around metropolitan areas, fence-line monitoring at industrial plants and hazardous waste sites, and in the production of high purity industrial gases. Methane is a naturally occurring gas generated from the decomposition of biological materials and industrial activity. Since Methane is not considered a pollutant it is the Non-Methane hydrocarbons that are of primary concern.

    Measurement of C1-C5 hydrocarbons for oil & gas exploration.

    The PetroAlert Model 8900 combines the selectivity of gas chromatography with the sensitivity, broad dynamic range, and hydrocarbon selectivity of a flame ionization detector (FID) providing fast analysis of C1-C5 hydrocarbons required in Mud Logging for Oil & Gas exploration. The PetroAlert Model 8900 uses a dual column configuration with timed backflush to vent which is used to strip off moisture and C6+ hydrocarbons. A pre-cut column is used in series with the analytical column. At sample injection a fixed sample volume is carried to the pre-cut column. Backflush of the pre-cut column is timed from sample injection so that only C1-C5 hydrocarbons are eluted from the pre-cut column to the analytical column. C6+ hydrocarbons on the pre-cut column are then vented. C1-C5 hydrocarbons are separated on the analytical column and elute to the flame ionization detector (FID) for analysis.
