A new static mixer delivers substantial cost savings

By Gerald Ondrey |

At Achema last month (May 11–15; Frankfurt, Germany), Sulzer Chemtech AG (Winterthur, Switzerland; www.sulzerchemtech.com) launched a new static mixer, the SMX plus. For homogenizing viscous fluid, the new SMX plus has about half the pressure drop of the company’s standard SMX of the same diameter. As a result, significant cost savings can be achieved by using smaller pumps or through reduced diameters, says Katharina Hänsli, manager chemical industry, mixing and reaction technology. Energy costs, for example, can be reduced by 20 – 30% due to reduced pumping demands, she says. The SMX plus is suitable for mixing viscous fluids (1,000 to 100,000 Pa s), such as polymer melts. Whereas dynamic mixers are typically used in batch applications, now processors can consider using a static mixer for continuous processing. One example that a customer has been testing with the SMX plus is for mixing two components, one with a high viscosity and another with a low viscosity, explains Hänsli. The new mixer was designed to fit into the same pipe sizes as the SMX, so it is easy to install as a retrofit. It can also be designed and fabricated to different codes, such as ASME or AD2000. Scaleup is no problem, as the mixer…
