A method for cleaning a coke deposit from an internal surface of a process equipment, comprising removing at least a portion of the coke deposit from the internal surface using a flexible pig comprising a plurality of bristles, without damaging a metal protective layer of the internal surface of the process equipment. A flexible pig for cleaning a coke deposit from an internal surface of a process equipment without damaging a metal protective layer of the internal surface, comprising a flexible body formed of a polymeric material, and a plurality of bristles partially encapsulated by the polymeric material of the flexible body.

A coke catching apparatus for use in hydrocarbon cracking to assist in the removal of coke and the prevention of coke build up in high coking hydrocarbon processing units. The apparatus includes a grid device for preventing large pieces of coke from entering the outlet of the process refining equipment while allowing small pieces of coke to pass through and be disposed of. The coke catching apparatus can be easily disassembled to be removed from the refining process equipment and cleaned.

One variation of a method for converting tires into pyrolytic byproducts includes: in a pyrolytic reactor, thermally depolymerizing a volume of rubber extracted from tires within an inert atmosphere into pyrolytic synthetic gas and solid carbonaceous material; within a centrifuge, removing from the pyrolytic synthetic gas residual solid carbonaceous material carried over from the pyrolytic reactor into the exhaust gas channel; within a vapor-liquid separator, separating vapor-phase pyrolytic synthetic gas from liquid-phase synthetic gas; depositing the liquid-phase synthetic gas into a heavy oil tank to form a cut of heavy oil in liquid phase; condensing a first portion of the vapor-phase synthetic gas in a light oil condenser to form a cut of light oil in liquid-phase; combusting a second portion of vapor-phase gas within a combustor; and recycling a third portion pyrolytic synthetic gas into heating elements within the pyrolytic reactor to heat the pyrolytic reactor.
