Gas drying apparatus and method

Details

Inventors: Dingfelder, Alan W.;
Assignee:
Primary Examiner: Smith; Duane S.
Assistant Examiner:
Attorney, Agent or Firm: Krayer; William L.

Apparatus for drying flowing gas includes a generally cylindrical vessel having a gas inlet and a gas outlet, two perforated plates of different metals in contact with each other transverse the interior of the vessel, and a third perforated plate downstream from the two mutually contacting plates.

DETAILED DESCRIPTION I have found that a certain arrangement of perforated plates will enhance the efficiency of moisture removal from natural gas.
Specifically, I use an upstream juxtaposition of perforated carbon and stainless steel plates, and a downstream deployment of a second perforated carbon steel plate, preferably separated from the other two perforated plates by a distance of three to ten inches, for natural gas having the common velocity of 1-2 feet per second within the vessel which holds the plates.
This arrangement of perforated plates is used in an expanded vessel--that is, one of larger diameter than the pipeline--providing a simple drain for the liquid recovered.
As will be explained below, the dehydrating action of the plates is associated with generation of an electric field which can be converted to current at the cost of drying efficiency.
