Continuous Affinity Recycle Extraction

In continuous affinity recycle extraction, instead of packing affinity adsorbent particles in a fixed bed, adsorbent/liquid contact is performed in well-mixed tanks. The adsorbent is continuously recirculated between two tanks. Each tank consists of two concentric cylindrical vessels. The wall of the interior vessel is made of a supported filter. The filter porosity is such that it does not allow passage of the adsorbent but only of the liquid stream and its soluble contents, so they can flow through freely. The affinity adsorbent is placed in the space between the concentric cylinders and is continuously recirculated between the two tanks. In one tank there is continuous adsorption of protein to the affinity adsorbent, whereas unbound materials pass through the filter to waste or recycle. In the second tank there is continuous desorption of product from the adsorbent, through the filter, to the collection apparatus. This technique can be applied to dye affinity adsorbents, particularly on a large scale.

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
