摘要： 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.

摘要： 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.

摘要： A system and method for repairing a coke oven having an oven chamber formed from ceramic bricks. A representative system includes a insulated enclosure insertable into the oven chamber and includes removable insulated panels that define an interior area for workers to work in. The insulated enclosure is movable between an expanded configuration and a compact configuration and moving the enclosure to the expanded configuration will decrease the distance between the insulated enclosure and the walls of the oven chamber. Removing the panels exposes the ceramic bricks and allows workers within the interior area to access and the bricks and repair the oven chamber while the oven chamber is still hot. A loading apparatus lifts and inserts the insulated enclosure into the oven chamber. The insulated enclosure can be coupled to additional insulated enclosures to form an elongated interior area.

摘要： The present technology provides systems and methods for detecting leaks in a coke plant. In some embodiments, the present technology includes discharging a gaseous tracer adjacent to a surface that at least partially divides a high-pressure system and a low-pressure system. The gaseous tracer can be measured at a location within and/or downstream from the low-pressure system to identify leaks in the structure.
