Advanced Depolymerization for Clean Energy Production

At the heart of World CleanEnergy Solutions lies the innovative Resident Time Technology (RTT), developed by ARTI. RTT is a high-efficiency, low-emission depolymerization system designed to convert a wide range of feedstocks—such as plastics, tires, biosolids, and RDF—into clean gas, electricity, fuels, or hydrogen.

Three-Stage Retort System

The RTT unit features a compact modular design with three retorts that enable controlled thermal decomposition of raw materials:
  • Upper Retort:
    Functions as a fast depolymerization zone, where raw materials begin their thermal breakdown.
  • Lower Retort:
    Operates at a higher temperature and longer residence time, ensuring full decomposition of heavy hydrocarbons.
  • Third Retort:
    Cools and slows down the gas stream to drop out carbon particles, improving gas quality before cleaning.

⇒ Residence time: Adjustable up to 3.5 hours, based on feedstock type and temperature profile.

Clean Gas Pathway

As feedstock breaks down into chemical components, the system can be tuned to maximize gas or preserve C5+ hydrocarbons for liquid fuels:
  • Gas Purification Process:
    1. Gas Separation: Heavier carbon particles fall out as gas slows to 3–4 ft/sec.
    2. Scrubber #1: Gas is washed with oil; separates water, carbon, and heavy condensable.
    3. Scrubber #2: Cools gas to ~110°F.
    4. Chilled Condenser: Final gas cooling to ~60°F removes 99% of condensable.
    5. Gas Blowers & Pressure Control: Maintains -2 to -4 in. WC vacuum in retorts.
    6. Storage & Compression: Clean gas stored for power generation or fuel use.

Byproduct Management

The RTT system is designed to achieve near-zero waste:

  • Carbon Black – removed via cooling auger and stored for resale or reuse.
  • Condensate Oils – centrifuged, reused for system cooling, or stored for sale.
  • Water – recovered and treated for safe discharge.
  • Gas – compressed and stored for electricity generation or hydrogen production.

Feedstock Requirements

Feed materials must be densified >20 lbs./ft³ for optimal gas output.
  • Tires: Shredded to <1.5″
  • Plastics: Shredded & pelletized.
  • Material Loading: Via augers or belts with automated feed controls.

System Outputs

Depending on configuration, the RTT platform can produce:
  • Clean electricity via gas generators.
  • Renewable fuels or diesel.
  • Green hydrogen (via SMR & PSA system)
  • Recovered carbon black and process oils.

Why RTT Technology?

  • Compact, modular, and scalable (100–300 TPD units).
  • Near-zero emissions.
  • Compatible with mixed and difficult feedstocks.
  • Adaptable for liquid fuel or hydrogen production.
  • Ideal for decentralized deployment and circular economy applications.
