In 2020, SRMG announced the award of a fly ash contract with a Utah power plant. SRMG is currently constructing a new fly ash beneficiation facility at the plant utilising the patented STET fly ash separation system. STET is supplying the separation equipment, engineering and commissioning services, and an exclusive technology operating license for SRMG. STET and SRMG are targeting operations to begin midyear.
“SRMG and STET have been working closely to develop a commercially effective beneficiation process improving the quality of the fly ash,” says Dale Diulus, SRMG Senior Vice President, Pozzolan Business Unit. “We look forward to many years of fly ash sales into the southwestern US markets.”
A recent study projects the global fly ash market to grow at a compound annual rate of 6.6%, reaching US$6.86 billion by 2026. “SRMG and STET are respected leaders in the fly ash and construction materials fields, and it is a good fit for our two companies to be collaborating on this project,” says Tom Cerullo, STET President. “The fly ash separator will be our first in the western US. We are excited to be working with Salt River to complete another successful fly ash project.”
The STET technology is the most widely implemented fly ash LOI reduction technology in the world. Loss on ignition (LOI) testing is a generally accepted method for estimating the unburned carbon content of fly ash. For over 30 years, STET, and its sister company Separation Technologies LLC (ST), have been leaders in providing dry powder separation equipment, technology and engineering services for the fly ash beneficiation, minerals processing, and now for protein-enrichment of food and feed.
