The E_OS (Energy Optimization through Sludge Treatment) project on the edge of Vienna is a pioneering facility designed to transform the Austrian capital’s wastewater treatment plant from a major energy consumer into a net producer. Important parts of the project therefore include maximizing energy efficiency and optimizing power generation.

PhosAgro is the biggest manufacturer of phosphate-based fertilizers in Europe. The largest site is the chemical cluster in Cherepovets, Russia, where the sulphuric acid is locally produced from elementary sulphur. Two new melters were built in an expansion project. It was essential to manage the heat transfer in the melters by agitators to ensure the capacity of the plant.

Large wastewater treatment facilities often incorporate an anaerobic digestion (AD) plant to handle sludge and deliver heat as well as electrical energy to support the operation of the site. Process performance depends on equipment reliability and getting the most out of the feedstock. Improved efficiency enables plants to increase throughput without expanding the site and this can be achieved by optimizing the sludge handling equipment.

Sulfuric acid is the key chemical used in the production process of wet phosphoric acid (WPA). Hence, the production of sulfuric acid close to the phosphoric acid plant (PAP) has many advantages. Not only does this reduce transport costs, but the nearby production of sulfuric acid, which is an exothermal process, allows the residual thermal energy to be used for the manufacture of concentrated phosphoric acid. Steam is generated to feed the heat exchanger located within the concentration unit of the phosphoric plant. Read the whole article.

Sulzer is at the forefront of engineering excellence and quality, delivering best-in-class solutions to support companies in important growth industries, such as biobased, renewable energy production. Understanding precisely what customers need, as well as maintaining the highest standards in manufacturing and service has led to many significant project wins, not least the collaboration with Inpasa, Latin America’s largest producer of corn ethanol. By the end of 2022, this partnership is anticipated to have grown to the delivery of almost 1’000 pieces of equipment, including pumps, sealing systems, agitators and static mixers across three production plants in Brazil.
