At four or six reactors, a tire pyrolysis plant is still a piece of equipment. At nine, it becomes a logistics operation.
That is the most useful thing to understand about the Liu'an project. In 2025, Shangqiu Jinpeng Industrial Co., Ltd. supplied nine sets of 15TPD batch-type tire pyrolysis reactors to an operator in Anhui Province, giving the site a design throughput of 135 tons of waste tires per day. The reactors themselves are the same proven 15TPD batch units Jinpeng builds for every project at this scale. What changes at nine lines is everything around them.
The clearest way to explain a plant of this size is to follow the material - from the tires arriving at the gate to the products leaving it.
1. The Intake Yard
A 135TPD plant consumes roughly 4,000 tons of waste tires a month. That volume has to arrive, be weighed, and be stored somewhere before it ever reaches a reactor.
This is where most first-time operators underestimate their space requirement. Waste tires are bulky and awkward to stack, and delivery arrives in irregular batches rather than on a steady drip. A site running nine lines needs enough buffer storage to keep every reactor fed through a slow collection week - without letting the yard become an uncontrolled stockpile that creates fire risk and draws regulatory attention.
The Liu'an layout was planned with intake staging and reactor feeding as separate zones, so that deliveries never interrupt the loading sequence.
2. The Reactor Hall
Nine batch reactors sit in a row, each running its own cycle: load, seal, heat, hold, cool, discharge.
The engineering inside each unit is consistent across Jinpeng's 15TPD batch platform - a horizontal reactor body with a reinforced sealing door, multi-layer insulation to hold thermal stability across the cycle, automatic feeding and discharge to cut turnaround time, and independent safety interlocks and pressure relief on every vessel.
What makes nine lines work is the sequencing. If all nine were loaded and fired together, the plant would swing violently between peak oil-gas production and complete idle. Staggered across the day, the reactors hand off to one another - one discharging while the next is at full pyrolysis temperature and a third is loading. The result is a continuous-looking output profile from batch equipment.
That sequencing discipline is the single biggest operational difference between a four-line plant and a nine-line plant.
3. Condensing and Gas Recovery
Oil-gas from all nine reactors is collected through a shared piping network and routed into the condensing system, where fuel oil is recovered and stored.
Gas that does not condense is not vented - it is recycled back into the heating system. At nine lines, this matters more than it does at four. The recovered gas volume from a plant of this size can displace a meaningful share of purchased heating fuel, which directly reduces operating cost per ton. Scale improves the economics of gas recycling, not just the output figures.
The flue gas treatment system is configured to applicable Chinese environmental discharge standards - a non-negotiable requirement for a plant of this visibility in a domestic industrial setting.
4. The Product Yard
Four output streams leave the plant, and each has its own handling logic.
Fuel oil goes to tank storage and out by tanker - the largest revenue line, and the one that dictates the storage capacity the site needs. Carbon black is discharged after each cycle, collected, and moved to bagged or bulk storage. Steel wire is recovered clean from the reactors and sold directly to scrap buyers, requiring no processing at all. Combustible gas, as described, never leaves the plant.
At 135TPD, all four streams generate volume at a pace that makes offtake agreements more important than equipment selection. A plant this size can fill its storage in days. Operators who arrange buyers before commissioning avoid the classic problem of a fully functional plant that has to throttle back because its product yard is full.

What Nine Lines Teaches
Jinpeng builds batch reactors at 10TPD and 15TPD, and continuous systems at 30TPD and 50TPD. Choosing between them is usually framed as a technical question. Liu'an suggests it is closer to a logistics question.
Nine 15TPD batch lines give an operator granular control: capacity added in defined increments, maintenance absorbed without stopping production, and cycle sequencing tuned to whatever the collection network actually delivers that week. The trade-off is that the operator must run a genuine scheduling operation rather than simply switching equipment on.
For anyone evaluating a plant above 100TPD, the Liu'an case makes the point plainly. The reactors are the straightforward part. Yard space, staging, cycle sequencing, and product offtake are what determine whether the installed capacity is actually realized.
