Abstract
A heat exchanger includes a shell, and a tube assembly disposed in the shell, the tube assembly including at least one tube, wherein the tube has a pair of end sections having a first diameter and a central section extending between the end sections having a second diameter that is greater than the first diameter.
Claims20
A heat exchanger, comprising:
- a shell;
- and
- a tube assembly disposed in the shell, the tube assembly comprising at least one tube;
- wherein the tube has a pair of end sections having a first diameter and a central section extending between the end sections having a second diameter that is greater than the first diameter.
1 more element
The heat exchanger of claim I, further comprising an outer shell configured to receive the shell and the tube assembly.
A desalination system, comprising:
- a heat source configured to produce steam;
- and
- a first shell-and-tube heat exchanger comprising an evaporator and a condenser;
- wherein the evaporator is configured to receive a feed stream of seawater mixed with the steam produced by the heat source and output a separated vapor stream and a separated liquid stream from the received feed stream;
- wherein the condenser is configured to condense the vapor stream produced from the evaporator into a distilled water stream.
2 more elements
A method for vapor-compression desalination comprising:
- (a) flowing a feed stream into an evaporator of a first shell-and-tube heat exchanger;
- (b) separating the feed stream in the evaporator of the first shell-and-tube heat exchanger into separated vapor stream and a separated liquid stream;
- and
- (c) condensing the separated vapor stream in a condenser of the first shell-and-tube heat exchanger.
