Silica Verfahrenstechnik GmbH products

Aluminiumoxide Gel (activated Alumina) (1). Used like Silica Gel, but immune to alkaline contaminations like NH³ or KOH.

Activated Carbon for the purification of waste gas and waste air, available in different qualities.

Drying of air, gases and liquids to residual humidity of less than 1 ppmv. Removal of contaminations from gases by adsorption.

Bead desiccant for drying of air and gases. Generally up to residual humidity corresponding  to dew point -65 °C.

Nearly all gases can be dried by adsorption. Dew points of less than -80 °C can be achieved. Our customers benefit from our extensive know-how in process technology resulting from the sales of more than 5,000 plants we have planned and built. Besides the dehydration of air and gases our plants can also be used for the removal of other components.

The drying of organic liquids is a special application of adsorption technology. Silica possesses comprehensive know-how for the design, layout, construction and assembly of such plants. Beside water other objectionable contaminations can be removed.

The purification of waste air by adsorption is especially suitable for reducing organic contaminations to very low residual concentrations. Generally the recovered solvents can be re-used. Due to decades of experience Silica is in a position to process also special substances and combinations of substances.

In the field of natural gas conditioning Silica offers adsorption plants for drying and simultaneous reduction of the hydrocarbon dew point. We have been building adsorption plants for more than 80 years, letting our customers profit from our extensive know-how.

Tank breathers type DTR and AFI have been developed specifically for the ventilation of storage tanks and transport vessels. The breathers are filled with desiccant, which prevents the entering of moist air into the tanks or vessels via the vent during breathing or discharging, thus protecting the contents and avoiding a corrosion of the tanks.

This procedure is typically used for the removal of O2, H2, CO or hydrocarbons from process gases. In addition, our special procedure is suitable for the removal of CO2 or methanol.
