DESIGN AND CONSTRUCTION OF A PROOF-OF-CONCEPT POULTRY LITTER PYROLYSIS PLANT

One of the challenges facing poultry farming is the safe and economical disposal of poultry litter (PL) waste. PL pyrolysis offers a solution and a commercial scale induction heated auger type reactor, was developed into an engineering solution through mathematical modelling, design, and construction. A 1 ton/day proof-of-concept plant was realized to validate laboratory scale experimental results, producing bio-oil, biochar, and gas at typical product yields of >50%, similar to 20% and <30% respectively. The pyrolysis plant was packaged into a standard ISO-container format, enabling complete fabrication and testing in a production line, whereafter it can be shipped to any remote location via road, rail, or sea freight, ready to operate by the turn of a key at arrival. With the addition of a heavy fuel oil (HFO) or gas-powered generator, the unit can operate self-sustainably as a stand-alone unit.
