Abstract: Reduced-waste systems and methods for granulated metallic units (GMUs) production are disclosed herein. A representative method can include receiving a first supply of molten iron and producing GMUs by granulating the molten iron poured onto a target material of a reactor. The method can include removing residual fines of the GMUs via a classifier based on a threshold particle size and mixing the residual fines with a second supply of molten iron to produce additional GMUs.

Abstract: A coke oven includes an oven chamber configured to support and heat a coal bed, a castable slab below the oven chamber, and a foundation supporting the heat recovery oven. One or more beams are positioned between the castable slab and the foundation. The beams extend from a first end of the oven chamber to a second end of the oven chamber, forming a plurality of air gaps between the castable slab and the foundation. Heat from the oven chamber is dissipated by the one or more beams.

Abstract: Systems and methods for removing carbonaceous clinker material from a coke oven are described. A coke oven can be provided including an oven floor, coke, and clinker material deposited on the oven floor. After a temperature of the coke oven has reached a first temperature (e.g., after heating coal in the oven to produce coke), the method includes increasing the temperature of the coke oven to a second temperature that is higher than the first temperature for a predetermined amount of time. After the predetermined amount of time, the temperature is reduced to a third temperature that is lower than the first temperature.

Abstract: 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.

Abstract: The present technology describes methods and systems for an improved quench tower. Some embodiments improve the quench towers ability to recover particulate matter, steam, and emissions that escape from the base of the quench tower. Some embodiments improve the draft and draft distribution of the quench tower. Some embodiments include one or more sheds to enlarge the physical or effective perimeter of the quench tower to reduce the amount of particulate matter, emissions, and steam loss during the quenching process. Some embodiments include an improved quench baffle formed of a plurality of single-turn or multi-turn chevrons adapted to prevent particulate matter from escaping the quench tower. Some embodiments include an improved quench baffle spray nozzle used to wet the baffles, suppress dust, and/or clean baffles. Some embodiments include a quench nozzle that can fire in discrete stages during the quenching process.

Abstract: Systems and methods of preventing an event occurrence or mitigating effects of an event occurrence in an industrial facility are disclosed herein. In some embodiments, a first input is received from a first sensor and, based at least in part on the first input, an initial action is automatically generated. In response to the initial action, a second input is received from a second sensor and, based at least in part of the received first and second inputs, a likelihood of an event occurrence is determined. Based at least in part of the determined likelihood, a remedial action configured to prevent the occurrence of the event occurrence is automatically generated. In some embodiments, the remedial action is generated in real-time and can be directed to a process condition, environmental condition, or secondary source.
