Measures both the Hydrocarbon dew point (HDP) and water dew point (WDP)
Duty: Measures both the Hydrocarbon dew point (HDP) and water dew point (WDP) by means of chilled-mirror technology
They are designed for continuous monitoring of the hydrocarbon & moisture dew points under the true pipeline conditions of flowing natural gas. If the pipeline gas includes traces of glycol, aerosols and/or particulate (etc.) contaminants, the appropriate sampling conditioning system can be provided with the analyzer in order to ensure reliable system performance.
Incremental measurements are made on the same spot until saturation occurs, when the tape is advanced to a fresh portion of tape. This reduces tape usage and avoids the need for frequent zero or span calibrations.
General characteristics of the CONG Prima-2M analyzer:
CONG Prima-2M in flow-through submersible design is intended to be mounted directly on the pipeline. Fields of application can be utilised in many process industries, including:
