Gas filter technology
Gas filter technology
(OP)
Im to begin with a small study involving gas filter technology for pipelinnes.
Im familiar with cyclone filters and cartridge filters - are there any other technologies that i might look into?
I know of PALL as a suitable vendor - any other obvious compnies?
Best regards
Morten

Other manufacturers for cartridge filters are Millipore, Sartorius, Parker, Domnick Hunter etc.
The comparision between a cyclone and cartridge is not proper, for cyclone efficiency is very low with reducing particle size.

Its dry natural gas from a offshore pipeline (very low HC and water dew point below -10ÂșC (HC below -30)).
At the receiving terminal there should be filters to remove unexpected liquids or solids.

Good luck.

I think you should go for a cyclone-cartridge filter combination.

Here is a partial bidders list of typical manufacturers:
Perry Equipment Corp. (PECO)
Burgess Manning
Peerless
King Tool
Winston (sometimes)
Each of the above manufacturers makes different types of separators so you can get a start on understanding your options. Your choice depends on whether you will receive mostly liquids or gas or a combination.
For the HC and water dewpoints listed above your problem is primarily removing solids such as mill slag, weld beads, dirt remaining from construction, etc. Most likely the only time the filter would see liquids is if there was an upset on the platform. So as long as there is not a slug then the filter-sep can handle it.
FYI, cyclone separators are sometimes used depending on the type of equipment downstream and the contaminent. Although the trend presently is toward filter-separators the cyclone has be used extensively at the inlet to compressor stations and meter stations with success. The cyclone will not remove as fine a particle as the filter but it is less maintenance and generally operates with a smaller differential pressure (higher pressure loss = additional HP = more fuel = more $$$$$).
Cyclone separators will generally remove particle sizes 8-10 microns and above. Read a recent study where a gas transmission company measured the condensate droplet size at the end of the line and found it to be larger than 10 microns.
Final thought. No vessel type separator will handle a liquid slug which is a whole new topic of discussion.
