Abstract: A reboiler for dehydrating glycol used in a gas dehydration system having improved thermal efficiency including a horizontal boiler vessel, a horizontal heater within the boiler vessel having a fuel burner therein, a heat exchange vessel extending downwardly from the boiler vessel including piping to receive heated glycol therein from the interior of the boiler vessel and a heat exchange conduit within the heat exchange vessel extending exteriorly of it, one end of the heat exchange conduit communicating with the interior of the boiler vessel to transfer wet glycol into the boiler vessel and a glycol inlet at one end of the conduit extending externally of the vessel and the heat exchange vessel having a dehydrated glycol outlet, hot dehydrated glycol from the boiler vessel passing downwardly through the heat exchange vessel to thoroughly exchange heat with the incoming wet glycol to thereby conserve heat applied to the glycol for dehydration.

Abstract: An improved absorber for dehydrating gas having water entrained therein utilizing liquid desiccants, the absorber being in the form of an upright cylindrical vessel having an upper and a lower partition dividing the vessel into an upper zone, a middle zone and a lower zone, the upper zone having a gas inlet therein and functioning as a desurging zone and the upper zone having a distribution gas outlet. A gas distribution conduit exteriorly of the vessel conducts the gas from the upper zone into the lower zone. A plurality of short length cylindrical members extend through the lower partition and are covered above the partition with cups. Above the lower partition is a quantity of packing and above the packing, in the middle zone, is a liquid desiccant inlet and above that, a dehydrated gas outlet.

Abstract: An improved absorber for extracting water or other liquid contaminants contained in gas including an upright vessel having a gas and a desiccant inlet, a gas outlet adjacent the top and a liquid desiccant outlet adjacent the bottom, a horizontal plate separating the interior of the vessel into an upper and lower chamber, a vertical mixing conduit within the vessel connected at its upper end with the vessel gas and desiccant inlets and passing downwardly through an opening in the plate, the vertical mixing conduit having a mixer element therein which intimately co-mingles the gas and liquid desiccant as they pass into the vessel and downwardly through the mixing conduit into the vessel lower chamber, a plurality of vertical cylindrical members supported in openings in the horizontal plate, the lower end extending below the plate and the upper end extending above the plate, a cap covering the upper portion of each of the cylindrical members, each cap having passageways in the lower edges thereof so that gas and

Abstract: An improved method of dehydrating wet gas including the steps of passing the wet gas into a pool of glycol contained within a vessel, the gas passing upwardly through the pool and through at least two zones within the vessel in which the gas is subjected to levels of glycol saturated packing within the zones, the gas passing upwardly within the vessel to a gas collection chamber for removal, the glycol being circulated from zone to zone within the vessel.

Abstract: A method of dehydrating wet gas including the steps of passing the wet gas downwardly through a vertical conduit, injecting anhydrous glycol into the vertical gas stream to intermix with the wet gas, passing the gas and glycol mixture downwardly within a vessel into a pool of glycol, the gas passing upwardly through the pool and into a gas collection chamber, the water entrained in the gas being absorbed by the glycol, the dry gas being passed out of the vessel, the glycol having water admixed therewith being conveyed to a water extraction means to provide a supply of anhydrous glycol and circulating the anhydrous glycol back to the vertical gas stream. The invention also encompasses a separator for extracting entrained water from a gas stream and including means for injecting the gas stream into a vertical conduit where it is mixed with glycol. The invention also includes an absorber wherein the gas stream is passed upwardly through a pool of glycol.
