Abstract
The current invention provides methods and apparatus for integrating a high temperature waste heat recovery system with a chemical or refining process which requires heat energy at a temperature less than the operational temperature of the waste heat recovery system. Additionally, the current invention provides methods and apparatus suitable for retrofitting existing process units requiring heat energy at a temperature of T2 with a waste heat recovery system operating at temperature of T1 where T1 is greater than T2.
Claims7
An integrated system for transferring heat energy from a waste heat source to a processing unit comprising:
- a waste heat transfer system and a pump free closed hydrostatic flow system;
- said waste heat transfer system comprising:
- a waste heat source;
- a waste heat exchanger;
- a first fluid circulation system providing fluid communication between said waste heat exchanger and said pump free closed hydrostatic flow system:
- a heat transfer fluid carried within said first fluid circulation system;
- said pump free closed hydrostatic flow system comprising:
- a waste heat vaporizer in fluid communication with the first fluid circulation system;
- a second fluid circulation system providing fluid communication between said waste heat vaporizer and said processing unit;
- a second heat transfer fluid carried within said second fluid circulation system of said pump free closed hydrostatic flow system;
- said waste heat vaporizer transfers heat energy from said waste heat transfer system to said pump free closed hydrostatic flow system and said processing unit.
