Case Studies and articles
Reliable SNS process pump for dewatering applicationsThe customer was running slurry pumps in a simple mine dewatering application, but wanted increased capacity and efficiency to reduce costs in the mine. The installation of Sulzer's high-efficiency SNS process pump gave remarkable annual energy savings.
AHLSTAR and SNS pumps throughout corn ethanol processFS Bioenergia, located near Lucas do Rio Verde, Mato Grosso, is the first corn-only ethanol plant in Brazil. The production started in 2017 and the annual capacity is 250 million liters today. The facility utilizes the latest process technologies from ICM, an innovative company headquartered in Colwich, KS, USA that has become a world leader in biorefining technologies and processes. In addition to bioethanol, some high-value coproducts such as corn oil as well as high-protein and high-fiber dried distiller’s grains are produced. The plant also generates electricity from the biomass, partly for internal use and the surplus for sale.
