Service Time Reduced to a Fraction with Sulzer’s New Shut-off Device for Agitators

Government initiatives to reduce emissions are gathering momentum, especially with many countries aiming for net carbon zero by 2030 or 2050. The building and construction sector is a particular focus, as it accounts for a significant amount of global energy- and process-related CO2 emissions, approximately 37% in 2021(i).

苏尔寿泵技术已被选by Raízen, Brazil’s largest producer of ethanol from biomass feedstock, as a supplier for their new second-generation ethanol (E2G) processing facilities. Sulzer is supplying a range of special metallurgy, process and utility pumps to process raw materials in support of renewable biofuel production for three new facilities. Made with sugarcane waste from Raizen’s conventional bioethanol production, E2G production has potential to increase efficiency by up to 50% while reducing emissions.

In appliances used for water purification and carbonated water, the valve of a carbon dioxide cartridge and the pressure-reducing valve on the device itself must be joined with a secure seal. Now, Freudenberg Sealing Technologies has developed a patented, high-performance polyurethane seal for a customer that has a specific geometry that not only accommodates different valve dimensions on the various gas cartridges, but also offers high impermeability under long-lasting pressure.

There are many pumps that have been performing vital operations for decades. Solidly built and offering reliable service, in some cases long after the manufacturer has gone by the wayside. However, there comes a time when even the most stoic of equipment needs to be refurbished, if only to improve performance and efficiency back to the original specifications.

Orders CHF 1’992.4m, + 24.1% YOY on robust growth momentum in all divisions. Sales CHF 1’601.6m, +15.4% in H1 on robust execution. Operational profit CHF 162.4m, +27.3% YOY, which reflects improvements in operations.

Sulzer’s expertise in rotating equipment retrofits and abrasive services has helped a Philippines petrochemical plant solve a persistent reliability issue and prepare for a 64% increase in capacity. Critically for the customer, Sulzer’s solution minimized the need for large-scale on-site modifications while extending pump mean time between failure (MTBF) from less than six weeks to three years.
