Hydrocarbon dewpoint detection and measurement

July 2002 Analytical Instrumentation & Environmental Monitoring

Ametek's Model 241CE dewpoint monitor is a quality control tool for natural gas processing, distribution and consumption. Detection and measurement of hydrocarbon dewpoint is achieved in a single cell, single cycle operation. Providing accurate monitoring of hydrocarbon dewpoints at pipeline pressure, the monitor may be located local to a plant or in remote locations. The monitor only requires electrical power and a supply of dry purge gas, allowing accurate readings to be obtained with little service and maintenance.

The dewpoint monitor is sensitive enough to detect trace amounts, yet strong enough to withstand saturation levels and process fluctuations such as temperature, pressure and flow rate. A proprietary multiple stage filter protects the analyser from most likely sources of contamination such as aerosols, particulates and liquid slugs. The programmable alarm system is automatically activated when problems are detected.

The monitor is an economic solution to detecting costly problems such as off-spec gas, plugged lines and compressor station malfunctions. A dewpoint monitor located anywhere on a pipeline ensures accurate and continuous monitoring, even at remote or hazardous locations.

Using chilled-mirror technology, the monitor is able to automatically monitor and measure dewpoints under the control of an onboard computer, rather than by an operator. The Model 241CE meets CSA Class 1 Div 1, Group C&D, and Cenelec Zone 1 certification for use in hazardous areas. The instrument is suitable for pipeline quality and custody transfer, specification monitoring and gas turbine feed gas monitoring.
