Abstract
Systems, devices, and methods comprising: a heat exchanger including: a shell including a first section and a second section, where one of the first section and the second section is one or more tubes disposed inside the shell, and the other is a void surrounding the one or more tubes inside the shell; the first section configured to receive hot fluid and recover heat from the hot fluid; the second section configured to receive cold fluid and generate steam using the recovered heat; a vacuum pump configured to lower a pressure of the second section inside the shell and receive the steam from the second section; and a vapor compressor configured to receive the steam from the vacuum pump and pressurize the steam.
Claims20
A system comprising:
- a heat exchanger including:
- a shell including a first section and a second section, wherein one of the first section and the second section is one or more tubes disposed inside the shell, and the other is a void surrounding the one or more tubes inside the shell;
- the first section configured to receive hot fluid and recover heat from the hot fluid;
- the second section configured to receive cold fluid and generate steam using the recovered heat;
- a vacuum pump configured to lower a pressure of the second section inside the shell and receive the steam from the second section;
- and
- a vapor compressor configured to receive the steam from the vacuum pump and pressurize the steam.
A method comprising:
- receiving hot fluid via a first section of a heat exchanger;
- receiving cold fluid inside a second section of a heat exchanger;
- lowering a pressure inside the second section by a vacuum pump;
- recovering heat from the hot fluid through heat exchange with the cold fluid;
- generating steam inside the second section using the recovered heat;
- and
- pressurize the steam by a vapor compressor,
- wherein one of the first section and the second section is one or more tubes disposed inside a shell of the heat exchanger, and the other of the first section and the second section is a void surrounding the one or more tubes inside the shell.
