Process Analyzers

The Industry Standard HCDP/WDP
Analyzer

The Condumax II fullls the demands of natural gas
producers and pipeline transmission companies for reliable
on-line monitoring of natural gas hydrocarbon and water
dew point.

Condumax II is the industry’s analyzer of choice to
ensure conformance of these key gas quality parameters,
from production processing, through trans-continental
pipeline networks into nal distribution and utilization by
major consumers such as power generators. Throughout
the midstream industry Michell hydrocarbon dew-point
analyzers are installed as permanent analyzers, providing
measurements six times every hour 24/7/365.

Transportable Condumax II for Field
Validation

The Condumax II Transportable addresses the further
needs of natural gas users as the industry evolves. With
an increased proportion of alternative fuel sources such
as biogas, and greater reliance on LNG imports into gas
networks which traditionally received gas solely from
xed upstream producers, the attention to ensuring
accurate measurement of dew point has never been more
critical. This increased complexity of supply chains has

expanded the number of potential measurement points

each requiring conformity to specication. The Condumax
II Transportable oers the exibility to make investigative
spot-check measurements at any location, to even the
smallest and most remote gas source. Furthermore, for
the gas producer, the Condumax II Transportable can be
used to prole individual process stages to ensure optimum
eciency.

Quality Assurance with a New Transfer
Standard

The Condumax II Transportable also enables established
users of permanent on-line dew-point analyzers to carry
out periodic comparative measurements in the eld to
verify measurement performance against the certied
factory laboratory calibration of the Condumax II to all
users.

The Condumax II Transportable oers automatic
measurements of high sensitivity and objectivity wherever
they are needed in a simple to use, self-contained, sample
handling, conditioning and analysis package.

Sample Conditioning System

• Complete integration of Condumax II Main Unit

• System conguration for connection direct to

transmission pipeline natural gas at typically 70 barg

pressure

• Simultaneous water dew-point measurement at process

pressure. Integration of water dew-point sample ow in

series for analysis at full line pressure

• Process pressure gauge, 100 barg scale

• Coalescing lter with by-pass needle valve and system
drain

• Sample gas pressure reduction via electrically-heated

regulator for analysis of HC dew point at intermediate
pressure (cricondentherm condition), adjustment range
up to 35 barg tted (analysis pressure indicated by
Condumax II Main Unit)

• Sample ow control with armored rotameter

*To assure correct measurement performance of

this system in outdoor eld use, the ambient air

temperature must be at least 5°C above both the

hydrocarbon dew-point temperature of the process

gas sample at the cricondentherm condition,

typically 27 barg, and water dew-point at full

process line pressure.
