Claim 10

The apparatus of claim 1 further comprising a preheating means having a preheated volatile-containing liquid outlet in fluid communication with said volatile-containing liquid inlet of said enclosure.

Claim 11

The apparatus of claim 1 further comprising a volatile-containing liquid pumping means in fluid communication with said volatile-containing liquid inlet.

Claim 12

A process for separating a volatile component from a volatile-containing liquid to produce a substantially volatile-free liquid comprising: (a) feeding a volatile-containing liquid to the upper end of an inclined enclosure; (b) distributing said volatile-containing liquid substantially downward across a top surface of an inclined flow plate positioned within said enclosure; (c) heating said flow plate by directing solar radiation onto said top surface through a transparent panel on the face of said enclosure; (d) transferring heat from said flow plate to said volatile-containing liquid flowing downward across said top surface of said flow plate; (e) agitating said volatile-containing liquid flowing downward across said top surface of said flow plate by means of spaced protrusions on said top surface aligned substantially perpendicular to the direction of liquid flow; (f) feeding a stripping gas to the lower end of said inclined enclosure; (g) conveying said stripping gas substantially upward countercurrent to the flow of said volatile-containing liquid through a head space within said enclosure above said flowing volatile-containing liquid; (h) entraining said volatile component from said volatile-containing liquid in said stripping gas as said gas flows through said head space; (i) exhausting said stripping gas and volatile component from the upper end of said enclosure; and (j) withdrawing said substantially volatile free liquid from the lower end of said enclosure.

Claim 13

A process for separating a volatile component from a volatile-containing liquid to produce a substantially volatile-free liquid comprising: (a) feeding a volatile-containing liquid to the upper end of an inclined enclosure; (b) distributing said volatile-containing liquid substantially downward across a top surface of an inclined flow plate positioned within said enclosure; (c) heating said flow plate by directing solar radiation onto said top surface through a transparent panel on the face of said enclosure; (d) transferring heat from said flow plate to said volatile-containing liquid flowing downward across said top surface of said flow plate; (e) agitating said volatile-containing liquid flowing downward across said top surface of said flow plate by means of spaced protrusions on said top surface aligned substantially perpendicular to the direction of liquid flow; (f) feeding a stripping gas to the lower end of said inclined enclosure; (g) conveying said stripping gas substantially upward countercurrent to the flow of said volatile-containing liquid through a head space within said enclosure above said flowing volatile-containing liquid; (h) entraining said volatile component from said volatile-containing liquid in said stripping gas as said gas flows through said head space; (i) exhausting said stripping gas and volatile component from the upper end of said enclosure; and (j) withdrawing said substantially volatile free liquid from the lower end of said enclosure.

Claim 14

Claim 15

The process of claim 11 further comprising preheating said volatile-containing liquid prior to step (a).

Claim 16

The process of claim 11 further comprising recovering said volatile component from said stripping gas after step (i).

Claim 17

The process of claim 11 further comprising releasing said volatile component to the atmosphere after step (i).

Claim 18

The process of claim 11 wherein said stripping gas is air.

Claim 19

The process of claim 11 wherein said volatile component is a hydrocarbon and said volatile-containing liquid comprises water and said hydrocarbon.

Claim 20

The process of claim 17 wherein said substantially volatile-free liquid is water.

Claim 21

The process of claim 17 wherein said hydrocarbon is gasoline.

Claim 22

The process of claim 11 wherein said volatile component is hydrogen sulfide gas and said volatile-containing liquid comprises water and hydrogen sulfide gas.
