Abstract
A method of controlling the rate of generating steam by direct heat exchange is provided in which a spray of hot oil drops contacts a spray of water drops. Large water drops are prevented from entering the effluent oil stream during upsets in operating conditions by providing suitable disengaging means such as heated sloped baffles below the contacting zone.
Claims13
A process for controlling the rate of production of steam, which comprises:
- contacting a spray of liquid water drops with a spray of hot substantially non-volatile liquid drops in a contacting zone to produce steam by direct heat exchange of said hot liquid and said water, said water drops having a mean average diameter of about one half the size of the mean average diameter of said hot liquid drops.
A process for controlling the rate of production of steam, which comprises:
- (a) introducing into a contacting zone a stream of hot mineral oil as a spray of drops;
- (b) introducing into said contacting zone a separate stream of liquid water as a spray of drops, said water drops having a mean average diameter of about one half the size of the mean average diameter of said hot mineral oil drops;
- (c) contacting said hot oil drops with said liquid water drops in said contacting zone to produce steam;
- (d) separating said steam from said oil;
- (e) recovering said steam, and
- (f) recovering a cooled oil.
