This field-mounted analyser station monitors the moisture content of propylene gas in the refinery's jetty area, before it is loaded onto tankers for export.
The Intraflow system was assembled to Preem Refinery's requirements and supplied as a ready to use module by Parker's Swedish distributor Items.
Tony Carlsson, the instrument engineer at Preem Refinery who specified the flow system commented: "This new surface mount technology substantially reduces the space required to assemble analyser stations, as well as the sampling volumes of the system - for more efficient measurement cycles.

The plug-together nature of the Intraflow substrate also greatly simplifies routine maintenance such as the replacement of filters.
That's a task that can now be accomplished in just a few minutes.
It's a very attractive solution and I expect to adopt it on future analyser installations and upgrades." Roger Wibbling of Items, added: "No welding is required with this form of modular substrate.
Parker Intraflow fittings plug together in seconds using novel slip-fit connectors, with finished systems occupying typically just 25 per cent of the space of a conventionally-plumbed alternative." Intraflow fittings are ISA/ANSI SP76.00.02 compliant.
The 1.50-inch (38.1mm) footprint modules screw onto a 'pegboard' backplane that provides the connection force and rigidity for the finished flow control assembly and may be disassembled rapidly for maintenance or re-use.
The Intraflow substrate has intrinsic support for three-way flow paths.
Unlike linear substrates in common use for semiconductor 'gas stick' delivery systems, Intraflow is claimed to maintain flow paths on a single plane - regardless of direction.
No manifolds on additional substrate layers are needed to implement the more sophisticated functionality required by sample systems.
This approach allows flow control substrates to be constructed with extremely low profiles (less than three quarters of an inch, or 20mm including the pegboard) and additionally optimises efficiency in terms of smaller internal volume sizes for faster sampling and purging cycles said Parker.
