Magnetic induction heating system for converting recycled polyethylene to industrial wax
A scalable system using magnetic induction heating to rapidly convert recycled polyethylene into industrial-grade wax, optimizing process parameters for maximum yield and quality, offering an efficient alternative to traditional methods.
Overview
The magnetic induction heating (MIH) system offers an innovative solution for converting recycled polyethylene (PE) into high-quality industrial wax. By leveraging rapid heating through electromagnetic fields, this technology promises faster processing, reduced energy consumption, and enhanced control over wax characteristics compared to conventional pyrolysis methods. This positions MIH as an ideal alternative for industries requiring efficient and sustainable production of lubricants and coatings.
Technical specifications
- Magnetic Induction Heating (MIH): Utilizes high-frequency magnetic fields to induce eddy currents, achieving temperatures over 1000°C within seconds.
- Process Optimization: Focuses on optimizing parameters such as coil frequency, susceptor material, and reactor design to maximize wax yield and quality.
- Scalability: Initial laboratory experiments use a 5 kW induction heater for 1 kg batches, with plans to develop a commercial-scale reactor capable of handling 100 kg/h.
- Product Analysis: Ensures wax meets industrial standards for melting point and viscosity.
Technology readiness level
This system is currently at Technology Readiness Level 4, with successful lab-scale validations. Future steps include pilot testing with a 50 kW reactor and commercial scaling to a 500 kW system, aiming for a wax yield of over 80% while minimizing byproducts.
