Xinhai is the earliest company who put forward the turnkey solution for mineral processing plant (EPC + M+O) in China, including mining technology consulting, mineral dressing test, mine design, equipment manufacture and procurement, engineering construction, installation & debugging, worker training, standard reached and operating management.
The most common way to increase gas/water contact and increase diffusion of carbon dioxide out is to employ a stripping column (degassing tower). A carbon dioxide stripping column is a counter flow packed column. A similar arrangement was described in the last chapter as an oxygenation method. The difference is that a carbon dioxide stripper is

Providing large air volumes to cascade columns is relatively inexpensive when airhandling or building ventilationtype blowers are used, because low back pressures (generally less than several cm of water pressure) against the fan require little power to move large volumes of air.

Chemical stripping Chemical absorption is the most suitable method for the separation of CO 2 from and cooled to nearly 50°C. Then, the gases go to the absorption column where the carbon dioxide binds to the solvent chemically. Most of the CO2 is thus removed from the exhaust gas that is released to the atmosphere and the reach solution

One of the most common ways to strip carbon dioxide out of the water is with a stripping tower. Here influent water from the culture tank with high CO2 enters at the top of a tower and is distributed for uniform loading. The tower internals may have water breakup of some sort like plastic packing. As the water passes through

Aug 01, 2003· The cascade stripping columns were placed in the recirculating system so that they would strip dissolved carbon dioxide after it had reached its highest concentration within the system and before any oxygen supersaturations have been produced, i.e. just after the water flows out of the biofilter and just before the water flows into the oxygenation unit.
