Abstract
A cement production system includes a wellbore extending from a surface into an underground magma reservoir. The wellbore is configured to heat a heat transfer fluid via heat transfer with the underground magma reservoir. Processes for cement production are driven at least in part by energy obtained from the underground magma reservoir.
Claims18
An industrial system, comprising:
- a geothermal system comprising a wellbore extending from a surface into an underground magma reservoir, the wellbore configured to heat a heat transfer fluid via heat transfer with the underground magma reservoir, thereby providing heated heat transfer fluid;
- and a cement product system comprising:
- a kiln configured to:
- receive a cement precursor;
- and
- sinter the received cement precursor using heat derived, at least in part, from the heated heat transfer fluid, thereby generating a clinker;
- and
- a mill configured to mix the clinker with one or more other components to generate cement;
- wherein the kiln comprises:
- a lining;
- and
- a heat exchanger disposed in or on a surface of the lining, the heat exchanger configured to:
- receive the heated heat transfer fluid;
- and
- transfer heat from the heated heat transfer fluid into the kiln.

A method of producing cement, the method comprising:
- heating a heat transfer fluid, transported through a wellbore extending from a surface into an underground magma reservoir, via heat transfer with the underground magma reservoir, thereby generating a heated heat transfer fluid;
- receiving, by a kiln, a cement precursor;
- sintering, by the kiln, the received cement precursor using heat derived, at least in part, from the heated heat transfer fluid, thereby generating a clinker;
- mixing, with a mill, the clinker with one or more other components to generate the cement, and
- by a heat exchanger disposed in or on a surface of a lining of the kiln:
- receiving the heated heat transfer fluid;
- and
- transferring heat from the heated heat transfer fluid into the kiln.
