Abstract
The heat removal and recovery systems of a nuclear energy source and the heat requirements of a nearby industrial facility are designed to achieve zero or near-zero greenhouse gas emissions from the industrial facility. Alternative arrangements of heat loops or belts to and from the nuclear heat source and within the industrial facility utilize heat exchange equipment at the interfaces and replace the use of fired furnaces and boilers. Technologies and processes can be selected to avoid the need or use of all or most of the furnaces and boilers. The design scheme applies to both new and existing retrofitted industrial facilities.

A method of reducing greenhouse gases emissions from a petroleum refinery, petrochemical plant, inorganic chemical manufacturing facility, bulk chemical manufacturing facility, or bitumen upgrader:
- Step 1:
- A heat carrying fluid comprised of hydrocarbon liquid, hydrocarbon vapor, a mixture of hydrocarbon liquid and vapor, a molten fluid, a liquid and solid slurry, a non-hydrocarbon mixture of liquid and vapor, or a mixture of solids and vapor being piped and pumped or compressed into heat exchange equipment in the heat removal section of a nuclear reactor assembly located either in an adjacent nuclear power generation plant or a mini-reactor located within the facility described in Step 2 with the fluid experiencing a temperature increase.
- Step 2:
- Fluid from Step 1, after experiencing a temperature increase, being pressured or pumped to a petroleum refinery, petrochemical plant, inorganic chemical manufacturing facility, bulk chemical manufacturing facility, or bitumen upgrader and flowing through a series of heat exchange equipment substituting for fired heaters, furnaces, or boilers needed for the particular processes in the facility, reducing or eliminating emissions of greenhouse gases due to the reduction of fired duty.
- Step 2 Alternate No. 1:
- Fluid from Step 1, after experiencing a temperature increase, being pressured or pumped to a petroleum refinery, petrochemical plant, inorganic chemical manufacturing facility;
- bulk chemical manufacturing facility, or bitumen upgrader and flowing through equipment in which heat is exchanged to another circulating fluid of a type described in Step 1, with the fluid in this secondary circulating loop being pressured or pumped through piping through heat exchange equipment substituting for fired heaters, furnaces, or boilers needed for the particular processes in the facility, and returning to the main loop heat exchanger, thereby reducing or eliminating emissions of greenhouse gases due to the reduction of fired duty.
- Step 2 Alternate No. 2:
- Fluid from Step 1, after experiencing a temperature increase, being pressured or pumped to a petroleum refinery, petrochemical plant, inorganic chemical manufacturing facility, bulk chemical manufacturing facility, or bitumen upgrader and flowing through equipment in which heat is exchanged in either series or parallel arrangements to multiple secondary circulating heat exchange systems, each secondary loop furnishing heat through heat exchange equipment substituting for fired heaters, furnaces, or boilers needed for the particular processes in the facility, and returning to the main loop heat exchanger, reducing or eliminating emissions of greenhouse gases due to the reduction of fired duty.
- Step 3:
- Cooled fluid circulating in the main loop being piped and pressured or pumped back to the heat exchange equipment at the nuclear heat removal equipment thereby completing the main loop.
