Systems and methods for particle leak detection generally include a separation or collection device configured to filter particulate from a stream and a detection device downstream of the separation or collection device. The detection device can be positioned to detect particulate that passes the separation or collection device and can include a probe configured to detect the solid particles. The particle leak detection systems can be configured to be disposed on moveable systems, such as moveable systems in coke oven operations.

The present invention provides a coking plant. The coking plant includes a series of coke ovens, each oven including a coking chamber provided with side unloading doors. The chamber communicates with a riser provided with a coking-gas discharge pipe. The discharge pipes of each oven lead into a collecting cylinder, which is in turn connected to a coking gas treatment circuit. At least one discharge pipe of one of the ovens further includes a device for spraying pressurized liquid onto the wall of the discharge pipe. The liquid flows counter-current with respect to the direction of the flow of the gases exiting the chamber. The present invention also provides a method for controlling such a plant.

A process and apparatus for improving the production of coke having a high volatile combustible material content are disclosed. The process may include, for example: heating a coker feedstock to a coking temperature to produce a heated coker feedstock; contacting the heated coker feedstock with a quench medium to reduce a temperature of the heated coker feedstock and produce a quenched feedstock; feeding the quenched feedstock to a coking drum; subjecting the quenched feedstock to thermal cracking in the coking drum to (a) crack a portion of the quenched feedstock to produce a cracked vapor product, and (b) produce a coke product having a volatile combustible material (VCM) concentration in the range from about 13% to about 50% by weight, as measured by ASTM D3175.
