Some of the typical applications are: elimination of O2, H2, CO or hydrocarbons from process gases and elimination of CO2 or methanol -among others- through special processes developed by Silica.
One of the special applications of adsorption technology is the drying of organic liquids. Silica has extensive knowledge about the planning, design and construction of this type of plants. In addition, other unwanted impurities can be eliminated.
In the area of natural gas treatment, Silica offers plants that allow at the same time to dry and reduce the dew point of natural gas hydrocarbons. In silica we have been designing and building adsorption plants for more than eighty years. Thus, our customers benefit from our extensive know-how of the process. Thanks to its immediate availability and its enormous flexibility of operation, the use of adsorption drying plants has given particularly satisfactory results in the underground storage of natural gas. The normal operating range corresponds to a processing capacity of 50,000 Nm³ / h at 600,000 Nm³ / h with a pressure of between 30 bar and 90 bar. The silica adsorption process also allows the dew point of water and hydrocarbons to be lowered in a single stage of the process.
The purification of exhaust air by adsorption is especially suitable for removing organic impurities. Solvents that are recovered in the process can be reused. The experience accumulated over several decades allows us to also treat special substances and mixtures.
