Dear $$first name$$ $$last name$$

We are very pleased by the information requests on our CLOSED COKE SLURRY SYSTEM following our newsletter from last April.

We appreciate that you, like us, are interested in improving the safety and operational aspects of your Delayed Coker Unit in an environmentally friendly and economical way. We concluded from some of the reactions more information is required about this fully automated, reliable, field proven system. For decades it has become self-evident that DCU and subsequent coke handling always associated with open pit/pad, dirt and dust together. However, even in the classic coker business there is still room for an unbiased view into traditional operations.

Our Closed Coke Slurry System does not have all this. Therefore, with this newsletter some more information, and our offer to organize a detailed presentation/discussion at your location at your convenience.

Closed Coke Slurry System

The very basic difference and unique offering of the CCSS is replacement of the traditional shute and open pit/pat design with a fully enclosed, fully automated system. Thus no more steam plum, no dust, no volatile organic components. While it is of course easier to implement CCSS right from the start in a new DCU, retrofitting existing units surely is possible as the footprint of the CCSS is smaller than any existing DCU.

An additional design flexibility of the CCSS is the location of the various components doesn’t have to be close to the DCU-drums, the slurry can be transported via pipeline, up to several kilometers, to remote power stations, gasification plants, calciner plants, etc. An interesting feature for refineries having space constrains, situated on hill slopes or near populated areas. Please refer to a relevant Triplan case study for additional information.

The process crushes and handles solids and water as slurry in a closed system followed immediately by a high efficient separation of water from the coke. An essential step change in solid handling accomplished with a total unique and field proven crusher design, the core equipment of the CCSS. The Triplan Crusher is directly placed underneath the coke drum (or unheading devices) and grinds the coke immediately in-line with the drum cutting/ream-out operation to the specified commercial lump size. The customized designed double roll with independent direct drive is fully automated through DCS. Consequent use of abrasive and corrosive resistant materials throughout the CCSS results in extraordinary high reliability figures (>99%) – not considered achievable so far - for this crucial processing step.

The very first Closed Coke Slurry System was installed at a German refinery in the 90’s. Over the years this initial design was modified, components and materials altered, specific equipment changed. The last modifications were implement during a DCU shut down in 2005 and ever since the unit has been running trouble free. It is with great pride we can state the engineers involved in these modifications and improvements are all employed by Triplan The refinery reports over this 10 year operation; no dedicated field operators required, high reliability factors, uninterrupted operation equivalent to 5000 cycles, no deterioration of slurry pump performances, no corrosion and erosion of the total CCS system, no fire, no accidents, no ‘near miss’ incidents, free water content of commercially dry coke lower 10% .

Currently Triplan is working on implementing a new CCSS in a refinery in Poland. The EPC contract for this project has been awarded to KT in Rome.
