Coke is a grey, hard, and porous coal-based fuel with a high carbon content. It is made by heating coal or petroleum in the absence of air. Coke is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges.

A coke pit in a refinery’s delayed coking unit had shown signs of deterioration on the pit walls and its integrated maze structure. In addition to corrosion due to chemicals, the walls were cracking and deteriorating due to the impact of front end loaders.

A coker crane in a petrochemical plant moves hot, fresh coke fuel in the coke pit out of the way of the coke drum so that coke gets cool down. After 24 hours, the crane moves the cooled, de-watered coke to a crusher, hopper, or conveyor.

TRIPLAN is offering a unique system for coke handling in a Delayed Coker Unit (DCU). compared with traditional DCU design. During our presentation we will highlight these unique features of the system, the benefits, and the many years of experience with extremely good results in an operating unit in Germany.

Aug 1, 2018 · A 30-foot high retaining wall of a coke pit suddenly collapsed at a refinery, flooding petroleum coke and water into the surrounding property. Fortunately, no individuals were injured in the incident, but the company suffered significant property damage and business interruption.

As the coke is ‘cut’ by the high pressure water nozzle, the coke and water flow onto a Coke Pad or into the Coke Pit, where the water is separated and recycled back to the cutting water system.

The coke pit is the production heart of a petrochemical plant, a harsh environment full of moisture, corrosive fumes and abrasive dust. Work is fast and continuous, and downtime is crippling to production. Konecranes can provide lifting equipment and service that can meet these challenges safely and efficiently.

Nov 26, 2012 · Crews repaired the coke pit by first pouring a leveling mud slab, then installing an under-drain system topped by a new reinforced concrete slab. A transition slab was built to join the new...
