Membrane drier stops gas lines freeze-up
Alta Gas, the UK's largest independent suppliers of LPG and bottled gas, has chosen a Beko Drypoint M membrane dryer for protecting gas tanks at four of its depots in the UK.
Alta Gas, the UK's largest independent suppliers of LPG and bottled gas, has chosen a Beko Drypoint M membrane dryer as the most suitable technology for protecting gas tanks at four of its depots in the UK Alta Gas plants run on compressed air, with tanks and other equipment situated in the open, which can create problems in winter when temperatures fall below zero

Fibre structuring in dryer saves energy costs
Latest generation of membrane dryers feature an evenly arranged structure of the fibres within the membrane elements that enables a more efficient distribution of purge air and lower energy costs.
The worst-case scenario would be for condensation to freeze in the pipes and the pipes to become blocked, causing the plant to fail.
A similar scenario occurring at LPG filling stations could create a potentially hazardous situation if filling guns were to become blocked.
Dennis Jones, health and safety consultant to Alta Gas, comments, "Drypoint M dryers are the only real solution to our needs because of their ability to run at sub-zero temperatures, even up to -10 degC if necessary.
Because the purge air acts as a power source for the modules, they are energy-efficient; they also require very little maintenance - a protection filter change twice a year is all that is needed - so they are extremely cost-effective to run." The Drypoint M can be used anywhere moisture occurs in service points.
Typical applications can be found in the pharmaceutical, food and beverage processing industries, breathing air applications such as paint spraying booths and product finishing such as plastics moulding processes.
Any areas, in fact, where humidity needs to be controlled to prevent loss of production.
The drying process is continuous.
Moist compressed air enters the module and flows through a bundle of highly selective hollow-fibre membranes, inside which there is a thin layer that can only be penetrated by water vapour.
At the outlet a small part of the compressed air is diverted and expanded for use as purge air, which then acts as a power source for the module.
Unlike a desiccant dryer, the operation does not have to be interrupted to purge the moist air, and unlike a refrigerant dryer, it does not cool the air around the pipe, causing more condensation. Request a free brochure from Beko Technologies ...
