Abstract
A system for removing moisture from a wet gas stream including a vessel having a contact area containing deliquescing salts that produces brine as water is absorbed, the brine flowing to a collection area in the bottom of the vessel. A venturi positioned in a wet gas inlet stream produces an area of reduced pressure that is applied to a brine flow path connected to the brine collection area. In this way, the brine is recirculated into intimate contact with the wet gas inlet stream causing the brine to be diluted with water extracted from the wet gas stream.
Claims11
A method of removing moisture from a wet gas stream comprising the steps of:
- introducing the wet gas stream through a venturi into a vessel having a contact area therein containing deliquescing salts that produce brine as moisture is extracted from the wet gas stream, the vessel having a brine collection area therein;
- siphoning brine from said collection area by use of said venturi whereby collected brine is recirculated in intimate contact with said wet gas stream, water absorbed from the wet gas stream serving to dilute the brine;
- withdrawing dry gas from an area of said vessel above said contact area;
- and
- withdrawing brine from said brine collection area.
A system for removing moisture from a wet gas stream, comprising:
- a vessel having a top and bottom and having a contact area therein below said top containing deliquescing salts, the vessel further having a wet gas inlet below said contact area, a dry gas outlet above said contact area and a brine collection area adjacent the vessel bottom;
- a venturi positioned within said wet gas inlet through which an inlet wet gas stream passes, producing a low pressure area, the wet gas stream passing upwardly through said deliquescing salts where water is absorbed forming brine that passes downwardly into said brine collection area;
- a brine flow path from said low pressure area to said brine collection area through which brine is recirculated into intimate contact with the inlet wet gas stream and by which the brine is diluted with water extracted from the wet gas stream;
- and
- a system to regulate brine level within said vessel brine collection area.
A gas dehydration contact tower comprising:
- an upright vessel having a top and bottom and having in an upper interior portion of the vessel a foraminous shelf that retains deliquescing salts thereabove, the vessel further having a dry gas outlet above said shelf and a brine collection area in a lower interior portion thereof;
- a venturi forming wet gas inlet in communication with interior portion of said vessel below said shelf;
- and
- a brine flow path extending from said venturi forming inlet to said brine collection area by which brine is recycled and intimately mixed with the incoming wet gas stream, absorbed water serving to dilute the brine, and the wet gas stream passing upwardly through said deliquescing salts by which water is absorbed, forming brine that passes downwardly into said brine collection area.
