Australia’s first grain-to-ethanol refinery has begun production in Queensland, with an expected output of more than 80 million litres a year. Seven pressure vessels and five columns were fabricated by Australian Stainless Steel Development Association accredited D&R Stainless from 30 tonnes of grade 304 stainless steel supplied by Australian Stainless Steel Development Association member Sandvik.

The column sizes range from an acid reduction column 750mm in diameter and 14.2m long to a beer column 1900mm in diameter and 24m long. The columns were fabricated to tight tolerances set by process design engineers Detla T Technology, United States of America.

Kevin Endres, Chief Executive Officer, Dalby Bio-Refinery Limited, has worked with Delta T technnology. According to Endres, stainless was chosen for its durability and a project of this size requires a low maintenance and reliable material. All design and manufacturing was carried out by D&R Stainless to ASME VIII complying with AS1210.D&R Stainless also fabricated 6000m of grade 304 piping in sizes from 20NB to 500NB requiring over 6100 elbows, flanges and fittings from Australian Stainless Steel Development Association member Stainless Pipe & Fittings Australia. All piping was x-ray quality and met ASME B31.3. The refinery can expand to output over 200 million litres of ethanol per year.
