Integrated coke plant automation and optimization using advanced control and optimization techniques
Patent number: 11788012Abstract: The present technology is generally directed to integrated control of coke ovens in a coke plant in order to optimize coking rate, product recovery, byproducts and/or unit lime consumption Optimization objectives are achieved through controlling certain variables (called control variables) by manipulating available handles (called manipulated variables) subject to constraints and system disturbances that affect the controlled variables.Type: GrantFiled: February 10, 2021Date of Patent: October 17, 2023Assignee: SUNCOKE TECHNOLOGY AND DEVELOPMENT LLCInventors: John Francis Quanci, Parthasarathy Kesavan, Jack Ziegler, Katie Russell, Mike Muhlbaier, Rakshak Khanna, Sharla Evatt, Milos Kaplarevic, Peter Chun -
Patent number: 11441078Abstract: The present technology is generally directed to systems and methods for optimizing the burn profiles for coke ovens, such as horizontal heat recovery ovens. In various embodiments the burn profile is at least partially optimized by controlling air distribution in the coke oven. In some embodiments, the air distribution is controlled according to temperature readings in the coke oven. In particular embodiments, the system monitors the crown temperature of the coke oven. After the crown reaches a particular temperature range the flow of volatile matter is transferred to the sole flue to increase sole flue temperatures throughout the coking cycle. Embodiments of the present technology include an air distribution system having a plurality of crown air inlets positioned above the oven floor.Type: GrantFiled: January 22, 2021Date of Patent: September 13, 2022Assignee: SUNCOKE TECHNOLOGY AND DEVELOPMENT LLCInventors: John Francis Quanci, Parthasarathy Kesavan, Ung-Kyung Chun, Rajesh Kumar Kandula, Mayela Carolina Fernandez, Khambath Vichitvongsa, Jeffrey Scott Brombolich, Richard Alan Mrozowicz, Edward A.

Patent number: 11053444Abstract: The present technology is generally directed to methods of increasing coal processing rates for coke ovens. In various embodiments, the present technology is applied to methods of coking relatively small coal charges over relatively short time periods, resulting in an increase in coal processing rate. In some embodiments, a coal charging system includes a charging head having opposing wings that extend outwardly and forwardly from the charging head, leaving an open pathway through which coal may be directed toward side edges of the coal bed. In other embodiments, an extrusion plate is positioned on a rearward face of the charging head and oriented to engage and compress coal as the coal is charged along a length of the coking oven. In other embodiments, a false door system includes a false door that is vertically oriented to maximize an amount of coal being charged into the oven.Type: GrantFiled: January 18, 2019Date of Patent: July 6, 2021Assignee: SUNCOKE TECHNOLOGY AND DEVELOPMENT LLCInventors: John Francis Quanci, Chun Wai Choi, Parthasarathy Kesavan, Katharine E.
