Yaphank, New York (PRWEB) August 07, 2014

COSA Xentaur a leader in innovative measurement solutions, today announced product updates to its Moisture Measurement Solutions for the Electric Generating, Transmission and Distribution industries. Major highlights include consistently accurate monitoring results for dew point in natural gas and other difficult hydrocarbon processing applications and a cost effective fully automatic self-calibration procedure. This dew point system has proven to produce consistently accurate monitoring results for dew point in natural gas and other difficult hydrocarbon processing applications, where conventional analyzers have failed.

Background
Natural gas is found in vast underground geological structures and can be extracted via wells. Another source of natural gas is from the refining of crude oil and most recently from a number of biofuel processes. All these sources produce a “wet” stream of gas requiring drying most commonly done with ethylene glycol. In some special applications, molecular sieve may be used. For moisture measurement, the natural gas industry is unique in that moisture is specified as a density measurement. In the US lbs/mmft3 (pound of H2O per million cubic feet of gas) at 60F is used. For Europe moisture is expressed as a pressure of dew point of 8C at 70 bara. Although these measurements sound quite different, from an absolute concentration point they are quite close - 143 ppmv H2O for U.S specifications and 151 ppmv H2O for European applications.

The Problem
As the moisture level increases the net energy available from burning natural gas decreases, potential for corrosion increases and damage to catalyst can occur. Sensors need to be protected by a coalescing element because there can be residual ethylene glycol and other aerosols in the natural gas streams so some type of filtration is normally required. Also, gas lines can be at high pressure or even varying pressures. To make measurements consistent, normally a pressure regulator is used. Calculations are required to make sure that hydrocarbon liquids do not form based on the Jule Thompson effect during the pressure drop.

The Xentaur Advantage
The Xentaur Mission Critical Process Moisture Analyzer is specifically designed to handle the rigorous demands of moisture in natural Gas applications. Due to a hyper-thin film and a special pore geometry, Xentaur sensors have a capacitance change over their full range, several orders of magnitude larger than that of conventional aluminum oxide sensors. Additionally, this change is quasi linear and its sensitivity to temperature is negligible.

Taking advantage of the uniquely strong and quasi-linear response characteristics of its HTF™ aluminum oxide dew point sensors, Xentaur has developed a cost effective solution for demanding and critical moisture monitoring applications.

The system has an integrated, fully automatic self-calibration procedure, in which the sensor is periodically exposed to a NIST certified calibration gas and recalibrated. Thus, there can be high NIST traceable confidence in the measurement and sensors do not need to be returned to the factory for calibration.

The advantages of a linear high capacitance response are: better sensitivity, better repeatability and faster response times. Also, the measurement system is less prone to noise and drift, and signal conditioning is kept to a minimum.

This dew point system has proven to produce consistently accurate monitoring results for dew point in natural gas and other difficult hydrocarbon processing applications, where conventional analyzers have failed.
