Static mixers for mineral extraction processes

A multi-stage static mixer is the perfect solution when a small flow of additives needs to be mixed into a main flow that has a (very) large turn-down ratio. In practice this often means for example adding just a few litres of additives into a main flow that can vary from 10 - 100% of the normal turn down ratio.

Static mixers are widely used in the water industry to mix specific chemicals in water, at water treatment and wastewater plants, in the production of drinking water and desalination plants. It is mainly the "trouble free" operation, 100% uptime and the high degree of homogeneity, which make the static mixer an ideal tool for the water treatment industry.

Before export gas is introduced into a pipe system, for further transport, several parameters of the gas are measured by, for example, ultrasonic measuring devices. Often condensate is also being admixed in the gas stream. Condensate is a product that rapidly condenses to a liquid. When the gas composition is not mixed well, measurements will be unstable as a result of the liquid present. This results in diagnostic values which lie outside of the specifications which is not acceptable for any further transport of the gas.

PRIMIX spends in its communication a lot of attention to new applications of static mixers and heat exchangers. This provides insights into solutions for special and challenging processes and enhances the transfer of knowledge, which helps to further develop certain fields of application. In addition to an application-oriented sharing of knowledge PRIMIX would also like to inform you about general issues and developments in the market. For this purpose PRIMIX will release a series of news items, which will start with the following article about the significance and change of the Pressure Equipment Directive (PED), this in relation to the manufacturing and application of static mixers.
