A City With Room for Two Plants
The usual first question is whether a city generates enough waste tires for one plant. The more revealing question - the one this archive entry is built around - is whether there is enough for two. Puyang, an oil-industry city in northeastern Henan, answered in 2018: Jinpeng's archive records two deliveries to the same city that year - a six-unit installation for one operator, and the four-unit, 48 TPD plant documented here for a second. A second plant in one catchment only makes sense once the first has shown that feedstock can be collected and product sold.
Project Background & Configuration Logic
Puyang, at the junction of Henan, Shandong, and Hebei and tied to the Zhongyuan oilfield region, generates a steady stream of truck and passenger tires through freight activity. By 2018 the city already hosted a six-unit Jinpeng batch installation; collection channels for scrap tires, buyers for fuel oil and recovered carbonaceous material, and a siting precedent all existed. A second operator did not need to build a market from zero; the work was sizing, competition, and operations.
Four units - 48 TPD combined design capacity - sit between a two-unit entry point (24 TPD) and the six-unit installation (72 TPD) that preceded them. The configuration shares supporting infrastructure across all four reactors: feedstock storage, product tankage, and the flue-gas treatment system, sized once for every line. Four units also divide into two pairs - a workable rotation without the scheduling load of a larger line count, and a sensible shape for a second operator sharing the city's tire arisings with an established one.
Core Technology & Production Analysis
What a Second Plant in One City Signals
A second pyrolysis plant in the same catchment is only buildable once the fundamentals are proven. Collection does not have to be invented: scrap dealers, truck fleets, bus depots, and tire shops already route used tires toward processors; a new plant competes inside those channels. Offtake is demonstrated too - the first operator's continued presence implies local buyers for fuel oil, recovered carbonaceous material, and steel wire. Read as a market signal, the four-unit plant suggests the city's tire arisings were sufficient for two installations - an inference from the archive record, not a statement about either plant's results.
Four Units as a Middle-Band Configuration
The 48 TPD combined design capacity sits between a two-unit entry configuration and the six-unit installation delivered the same year. For a second operator in a competitive market, four units balance throughput against feedstock risk: enough capacity to justify shared utilities and a proper treatment train, but not so much that the site depends on winning most of the city's tires. The four reactors are identical XY-8-P/PB batch units of 12 TPD design capacity, arranged around one process area with room for later units.
Batch Rotation Across Four Lines
Each batch unit follows a cycle of roughly 22-24 hours: loading, preheating, pyrolysis, cooling, and discharge. Staggering cycles means two lines can be in the pyrolysis stage while a third cools and a fourth is loaded or discharged. The benefit is not more throughput but a flatter demand on labor and logistics: intake is batched to match the moment a reactor is ready, and product leaves the tank farm steadily. Design guidance for this class assumes one to two operators; staggered cycles keep that realistic.
Intake Competition and Feedstock Planning
Two plants in one city plan intake differently from a lone operator. Sourcing breadth matters: passenger-car and truck tires differ in mass, wire, and composition, and accepting whole or cut tires widens the supplier pool. The batch design helps: each 12 TPD unit takes its charge in one loading operation at the start of a cycle, so tires accumulate in storage and reactors are loaded when supply has built up, not from a continuous incoming stream. The storage buffer is the practical answer to feedstock competition - when collection patterns shift, a stocked yard buys time.
Product Streams and Their Boundaries
The recovered streams are pyrolysis oil, recovered carbonaceous material, steel wire, and non-condensable gas - and naming them precisely matters. The oil is a fuel-oil stream; a diesel specification such as EN590 would require further distillation, hydrotreating, and certification testing. The solid is recovered carbonaceous material, not commercial carbon black unless deep-processed and tested as such. The non-condensable gas may be returned to the heating system where the installed design and operating conditions permit. In a two-plant city the market for these streams is shared - one more reason moderate scale, storage, and steady rotation matter.
Emission Treatment Under Shared Scrutiny
A city already hosting one pyrolysis plant has a reference point for the second. The installed treatment design for this plant class is a closed, micro-negative-pressure system in which flue gas passes through a spray tower (alkali neutralization) and an adsorption tower (desulfurization and dedusting), designed to meet applicable local emission requirements. Under proper operating conditions and after the installed treatment system, environmental performance depends on the auxiliary equipment and how it is run - the key check in a two-plant city is whether the treatment train is sized for the full 48 TPD design load.

What the Project Demonstrates
This project demonstrates that a Jinpeng batch configuration can be replicated within a single city - a second operator in a mature catchment is supportable. For a buyer whose city already hosts a pyrolysis operator, the value is concrete: a second plant sized to share a market rather than monopolize one - four units, shared utilities, staggered rotation, and a storage buffer as the answer to feedstock competition. Evaluators should watch three things: intake sourcing across tire types and suppliers; shared product offtake priced accordingly; and a treatment train sized for the full combined design load. The project does not prove current operating results - no recent revisit exists - but it documents a configuration answer to a competitive market.
