Gas Separation

Jord offers a range of hydrocarbon separation and treatment technology, be it solids and liquids from gases or the separation of liquids of differing densities. Custom-designed solutions may be capital equipment or modularised systems. Our technology lends itself to plant retrofits, where superior process performance can often be achieved with minimal expenditure. Jord’s record is well proven with many hundreds of successful installations in operation for the global oil, gas and petrochemical industry.

With a plot space of 200m x 100m and a condensate storage capacity of 7,000 m3 (44,000 bpd) the below harp type slug catcher is one of the largest in the world. Harp type slug catchers separate liquid hydrocarbons from natural gas. They are used where condensate volumes are too large for separation in a vessel. Harp type units are designed to ANSI/ASME pipe codes rather than pressure vessel codes. The below harp type unit features a unique pipe support system designed to guarantee robustness in this typhoon prone area in the south of China.  

Services include inlet and production separators, slug catchers and test separators. Jord’s design can incorporate a range of technologies including cross flow plate packs, vanes and high efficiency axial cyclones. The below image shows a three phase separator delivered to a Thai offshore gas plant. Vessel material was 904L clad. Internals included a vane inlet, calming baffles, a weir, a heating coil and a sand jetting system.

Filter coalescers are used in wet services to remove liquids from gases. This image shows 6 of 157 filter coalescers servicing one of multiple compression stations along a 7,300 km pipeline that spans China, from Horgos in western Xinjiang Province to Fuzhou in the east coast province of Fujian. The coalescer element achieves a higher liquid extraction performance than a conventional cartridge filter.  

The accompanying image shows some of 1,300 gas coalescers supplied to a coal seam gas gathering field in Queensland, Australia.

The accompanying image shows a 2.0 M ID X 4 M long Filter Separator which is one of eight filter separators supplied for a large pipeline project in Malaysia. These units feature reduced opening closures to minimise expense. The filter element carriers are specially designed to allow removal of the filter elements through this reduced opening.  

These are used to separate liquids from gases in a variety of applications including product recovery and gas pipeline transmission. Designs incorporate various inlet devices and de-misting technologies.

The below image shows a vertical separator located in Central Australia. The separator is a two phase gas/liquid separator using a vane inlet device and axial cyclone elements to separate the two phases under a high operating pressure.

Suction and discharge scrubbers for gas compression applications incorporate multi reverse-flow cyclones, axial cyclones and vane packs. The below image shows 3 of 6 scrubbers supplied to a gas production facility in the eastern jungle region of Peru.

Existing equipment can often be successfully de-bottlenecked, performance enhanced or otherwise improved by simply re-configuring or upgrading the process internals. The below image shows process internals retrofitted into a slug catcher in a Malaysian gas plant. The unit had inherent design issues which prohibited design performance being attained. Jord designed an alternative internals system, comprising a vane inlet device, vane pack and outlet piping, in a manner that allowed installation through a 24” manway. The retrofit took place without the need for any hot work (welding). Design performance was thereby achieved.

Jord designed, manufactured and commissioned a liquids management system for a coal seam gas hub station that collects natural gas from various smaller well heads. Scope included two multi-cyclone separators, liquid storage tanks and associated instrumentation and panels. The primary function of these scrubbers is the removal of glycol generated from an upstream gas dehydration package.

Filter separators are preferred where gas is contaminated with both solids and liquids. The below image shows a horizontal filter separator located in Victoria, Australia. The separator is a 2 stage gas/solid/liquid separator. The first stage uses filter elements to remove solids and to coalesce small droplets of liquid into larger droplets. The second stage uses a unique high efficiency vane pack to remove these larger droplets.
