Initiative 2: Innovative Alternative Distillation Technologies for the reduction of Fossil Fuel Consumption
Alternative Distillation Identification – completed
The objectives of this project is to build efficiency, resilience and sustainability through a detailed assessment of Tarac’s distillation systems against world’s best practice.
Alternative Distillation Evaluation – completed
Tarac engaged Process Energy Technology to design a system to reuse the University of Adelaide’s distillation column combined with membrane technology.
Greenfield Marc Distillation – completed
Desktop study on the feasibility of an adaptation whereby the ethanol vapour is fed directly from the marc stills into distillation column.
Alternative Marc Processing – completed
Identify alternative marc distillation processes. Conduct trials at winery for washing fresh Grape Marc to extract alcohol and tartrates.
Improve Product Quality – removal of undesired compounds – completed
Collaborate with the University of Adelaide with the main aim to effectively remove esters, isopropanol and n-propanol from final product.
Improve Product Quality – Identify taint compounds – completed
Collaborate with the University of Adelaide to identify taint compounds and gain an understanding of the source of taint.
Combination of Membrane technology with distillation – completed
Explore suitability to use pervaporation (PV) process at Tarac’s Griffith NSW site to concentrate low wine from 55% to crude alcohol at 90%.
Spirit treatment with air ozonation – completed
Conduct bench-scale study to determine the effectiveness and financial viability to use air ozonation to improve spirit quality.
Improving simulation with binary coefficient – commencing June 2021
The aim of this research is to determine the binary coefficients of the different components in low wine that enables the simulation software to provide a more accurate production plan and predict the problems that can affect the quality of the product.
