TEMA Process B.V. products

TEMA Process design for continuous Jet bag Filters is based on the process data and local conditions and can be offered “Taylor-made” suitable for the application

Packed tower scrubbers are used to remove particulate and / or vapor contaminants from an exhaust gas stream by way of dilution or absorption. A packed tower is an efficient method of carrying out mass transfer between gas and liquid phases. Packed tower scrubbers incorporate packing media to facilitate intimate contact between a scrubbing liquid and gas to be scrubbed.
Applications are: reduction of dust or gaseous emission levels, product recovery, air pollution and odor control. In countercurrent scrubber operation, the gas flows upward through the packing material, while the liquid flows downward by gravity through the
packing material. The liquid wets the surfaces of the packing material, providing a large amount of surface area for diffusion of one or more components of the gas stream into the liquid stream, thereby cleaning the gas.

Venturi scrubbers are used to remove particulate matter from a gas stream. A „Venturi Scrubber“ consist of a contact section called a venturi section in combination with a droplet separator section.

A Cyclone is a relative simple device that uses centrifugal force to separate larger particles from air streams. It is a high capacity / high efficiency separator  that also can be used in combination with fluid bed Dryers / Coolers, Jet bag Filters, Packed Tower Scrubbers and other process equipment. Diameters from 400 to 2000 mm.

The Tema Process dehumidifier is using a Lithium Chloride salt solution as absorbent. Lithium Chloride is a very strong salt and has an equilibrium curve which closely follows the relative humidity curve of air. The process air will enter the countercurrent dehumidifier and will be dehumidified or humidified in order to maintain this equilibrium. In other words the sprayed salt concentration will control the outlet air relative humidity. By cooling the salt solution before spraying we are able to cool down the air temperature. In this way air temperature and air humidity are both controlled in the same system but can be adjusted independently.
