RIPP – Overall Process Flow Summary

In summary, the process sequence in a RIPP scrap tire conversion facility is as follows: (i) tire supply and preparation; (ii) pyrolysis; (iii) magnetic separation of carbon black and steel; (iv) condensation of gasses; and (v) processing of the carbon black (beading and bagging).

In terms of tire supply, there is abundant availability; every year several hundred million tires are discarded in North America, in addition to millions of tires already stockpiled in waste dumps.

After the tires are prepared, thermal calciners are used as the primary processor of the shredded clean tire pieces. The rotary calciner is a two stage continuous feed processor with a seal arrangement at each extremity allowing for controlled atmospheres within the process chamber. This pyrolysis process is a continuous flow system that creates no waste.

The gases generated by the process are either condensed as oil or remain uncondensed as usable gas. The resulting end-petroleum products of gas and oil are available for external marketing. The oil can be used as chemical feed stock or as clean fuel depending on local and market drivers. The Company’s proprietary process allows for the tight control of all carbon black and petroleum product specifications.

The raw carbon black and steel are conveyed to the magnetic separators. The steel is removed and stored for delivery to end user as scrap clean steel. The carbon black is then prepared to exact specifications and stored in temporary surge tanks. The fine carbon black powder is subjected to further proprietary processes that create carbon black with the bead size and hardness required by rubber and plastic manufacturers.
