The scope was design and procurement of a Coke and Tar Removal Package (CTRP) from the quench water loop at the ethylene plant (EP). The CTRP removed coke without any necessity for shutdown of the quench water loop, with no negative impact to the environment and to health and safety.

The principle of the process is the continuous removal of coke solid particles in hydrocyclones with subsequent mechanical filtration in special process filters with a unique washing process in order to achieve a free-flowing and dry bulk coke particles. This patented process of the system has been developed and is owned by Intecha (process technology).<s></s>
Installation of the coke and tar removal unit increases EP efficiency and significantly saves operational costs, increases operational life of the equipment and it also reduces contamination of the environment. Incorporation of this process enables ethylene units to prolong operational cycles between shutdowns.
To minimize the site works, reduce execution time and assure high quality, the modularization strategy for this Coke Tar Removal Package was selected. The complete CTRP was fully manufactured and tested in vendor workshop and then divided in 4 modules (3 pcs of the Cyclones/Strainer modules and 1 pc of the Staircase/Service module) and handed for a road transportation. Keeping construction (main equipment, steel structure, piping, insulation, instrumentation, electro) in a workshop also helps to maintain low costs and increase safety.
