Abstract: A system and method for controlling operations of a cement kiln plant. The system comprises first and second processing logic. The first processing logic is configured to perform an integrated modeling computer program comprising a Virtual Cement and Concrete Testing Laboratory (VCCTL) modeling computer program and a virtual cement plant (VCP) modeling computer program. The first processing logic receives output of the VCP modeling computer program and imports the output into the VCCTL modeling computer program. The second processing logic is configured to perform one or more multi-objective metaheuristic optimization computer programs on output of the integrated modeling computer program to adjust control parameters that are used to control the operations of the cement kiln plant.

Abstract: Various examples are provided related to manufacturing portland cement with thermal plasma. In one example, a method includes providing a raw kiln feed to a plasma arc gasification kiln; and forming clinker by heating the raw kiln feed in the plasma arc gasification kiln. The raw kiln feed can be heated with a plasma plume supplied with argon gas to a temperature in a range from about 1800° C. to about 3000° C. In another example, a system includes a kiln feed system and a plasma arc gasification kiln that receives raw kiln feed from the kiln feed system and heats the raw kiln feed with a plasma plume to form clinker. The system can include a clinker processing system configured to process the formed clinker to produce portland cement.
