Engineered Products
GLP engineers, fabricates, and offers support for installation and trial fits of large variety of mass transfer internals for use in many process applications.
GLP Engineering has over 25 years of experience in custom design and retrofitting a diverse range of vessel internals such as column packing (structured and random), support plates, liquid and vapour distributors, mist eliminators (mesh pads and vane packs), inlet cyclones, multi-cyclones, axial flow cyclones, splash baffle and liquid-liquid coalescer packs across Australia and overseas.
We use proprietary and licensed software for the design of internals as well as vessels such as scrubbers, absorbers, stripping column and two-phase/three-phase separators.
GLP also hold sufficient stock of random packing in different sizes and materials at our warehouse facilities in Melbourne for emergency shutdowns and/or rapid turnarounds thereby avoiding plant shutdown losses due to non-availability of the packing.
GLP has also fabricated internals such as support plate up to 6.0 metres in diameter and in exotic material in a short frame of time for supporting Clients during emergency shutdown.
As part of our design deliverable, GLP provides hydraulic and performance rating calculations for the internals that are designed using proprietary software and offers complete process guarantee and mechanical warranty for all internals that are designed and supplied.
GLP’s engineers have over 25 years of experience in the installation of mass transfer internals in a safe and appropriate manner and will provide tailored support to the clients depending upon their requirements.
Mist Eliminators
GLP design and supplies a variety of high quality mist eliminators. These include:
- Vane Packs
- Chevron-type
- Single Pocket-type
- Double Pocket-type
- Mesh Pads
- Metallic
- Plastic
- Fiberglass
- Co-knitted materials
- Mesh/Vane Combos
- Fibre Bed Candles
- Polypropylene
- Polyester
- Glass Fibre
GLP provide quick and accurate mist eliminator design, taking into account all process parameters. Design and rating sheets are available upon request; so-long as sufficient process and mechanical input data is provided.
Materials of construction are typically stainless steel (304/316SS), super duplex, hastelloy or plastics such as polypropylene (PP) and more specialised fluoropolymers. Specialised co-knitted metallic wire mesh with glass fibre and PTFE multifilamanents are available for fine mist applications.

Packed Tower Internals
Liquid distributors
Packed towers are designed on the basis of equal liquid and gas superficial velocity across the column cross section. The pressure drop across the packing provides a means for the upward flowing gas to become uniformly distributed across the column area. However, as the liquid flows down the packed bed by gravity it has poor cross mixing tendencies therefore it is important to ensure uniformed liquid distribution at the top of the packed bed. Distributors are internals which are installed above a packed bed to provide a finite liquid distribution over the packed bed, it allows liquid to flow in discrete streams. This can be done with through orifices or V-weirs, located on/in the distributor. Distributors also provide a separate passage for the upward flowing gas.
Bed Limiters
Bed limiters and hold down plates are retaining devices used to prevent fluidisation of packing during operational upsets. Movement of packing can cause efficiency loss, therefore bed limiters are used for both random and structured packing. They are fastened to the column wall by means of support ring or bolting clips. They can also be suspended on tie rods from the liquid distributor.
Bed limiters rest directly on packing and can prevent ceramic packing from breaking up due to fluidisation when operated at high pressure drops or during surges. Bed limiters are designed to provide high open-area and reduce interference to liquid flow. They should be designed to withstand upward forces acting on the packed bed.
Flash Gallery
A liquid distributor will not function properly if vapor is trapped in the liquid which creates uneven hydraulic head across the distributor. Flash feed devices separate the vapor in the feed so that only clear liquid is introduced onto the distributor.
Packing Support Plate
Support plates are used to physically hold up the cumulative weight of the packing and the operating liquid hold-up in the packed bed. Support plates are shaped and designed to provide the maximum open area and minimal pressure drop. Factors that influence the choice and design of the support plate include the column diameter, design loads (mechanical and hydraulic), packing type, liquid hold up and system corrosively.
GLP packing support plates are designed to promote maximum capacity gas injection, with perforated beam design for optimal strength. These support plates are manufactured in sections to fit through vessel manways and can be manufactured from a wide range of materials.

Gas / Liquid Separation
2-Phase & 3-Phase Separators
GLP uses licensed technology for custom design and optimisation of 2-phase and 3-phase separators equipped with a wide variety of high-performance internals such as:
- Inlet devices (multi-vane, inlet cyclone, inlet deflector)
- Liquid-liquid coalescers (plate type, stokes type)
- Mist Eliminators (chevron, mesh type, axial flow cyclones)
- Multi Cyclones (removal of solid and liquids from gas)
- Sand Jet System (multispray nozzles, torr-jet type)
GLP provides CFD modelling design and hydraulic calculations for vessel and internals as part of our ongoing service to our clients.

Venturi Scrubbers
The High Energy Venturi Scrubber is ideally suited to the capture of small particles less than 3 microns in size. It is effective as well in the submicron range and requires little or no maintenance. For applications where variations in gas flow require throat gas velocity compensation to maintain specified scrubbing efficiencies we can offer automatic and manually variable throat designs.
GLP has successfully supplied and installed high energy venturi scrubbing technology in fume and fine particulate (sub-micron and PM2.5) wet scrubbing applications.
