In January 2026, DOING Company delivered two sets of 15T semi-continuous plastic pyrolysis plant to a client in India. The client, a plastic granulation business, generates substantial waste from its production processes had become a source of concern for them, and they purchased pyrolysis equipment specifically to process this waste.
DOING 15T semi-continuous plastic pyrolysis plant
The Indian client's decision to partner with DOING Company was primarily driven by the proven operational stability, processing efficiency, and long-term durability of our pyrolysis plant, complemented by our comprehensive after-sales support.
1 Two complete 15-ton semi-continuous pyrolysis plant main bodies, each equipped with feed hoppers, feed augers, rear slag discharge augers, buffer tanks, and high-efficiency standard tube-and-shell condensers.
2 Two dedicated carbon black discharge units with integrated augers.
3 Two advanced odor removal systems and two water-spray dust collectors to ensure environmental compliance.
4 Eight powerful 300,000 kcal heavy oil burners, mounted on two robust furnace bases.
5 A carbon black storage silo and a carbon black briquetting machine for byproduct value addition.

Underscoring DOING's commitment to superior quality, these semi-continuous pyrolysis plants are built to exacting standards:
Reactor Material: The core pyrolysis reaction vessel is constructed from robust boiler-grade steel plate, measuring 16mm thick. This material selection ensures exceptional resistance to high temperatures and plastic pyrolysis corrosive environments, critical for prolonged operation.
Welding Integrity: Precision is paramount in pyrolysis plant manufacturing; our automatic submerged arc welding process guarantees 100% defect-free seams. This advanced technique prevents leaks during continuous operation, enhancing safety and efficiency.
Sealing System: A full-perimeter sealing structure, combined with water-cooling protection, allows for stable and continuous operation at temperatures up to 450°C without any oil or gas escape, ensuring a secure working environment.
Key Components: The standard tube-and-shell condensers utilize seamless steel tubes, maximizing heat exchange and cooling efficiency. Crucially, the feed and discharge augers, designed for handling diverse plastic waste, are crafted from wear-resistant alloy and surface-hardened for an extended service life.
DOING pyrolysis plant design details
The 15T capacity semi-continuous pyrolysis plants ordered by Indian customers are engineered for high throughput, capable of achieving impressive oil yields of 45-55%, depending on the mixed plastic waste composition. The semi-continuous design significantly reduces manual intervention for feeding, slag discharge, and temperature control, requiring only 2-3 operators per shift.

Environmental protection devices are integrated, with the inclusion of an odor removal system and a water-spray dust collector. These systems effectively manage exhaust gases and particulate matter, ensuring the pyrolysis plant meets stringent local environmental regulations in India. Furthermore, the client's strategic inclusion of a carbon black storage silo and briquetting machine, enabling the profitable conversion of carbon black byproduct into marketable briquettes.
Currently, these two sets of 15T semi-continuous plastic pyrolysis plant is fully loaded and en route, expected to arrive at the Indian facility within approximately 40 days, ready for the installation phase.
