ACTIVATED CARBON TREATMENT |
摘要 |
<p>The present invention relates to a process for purification of a compound using an activated carbon treatment. In the process according to the present invention several filter units containing activated carbon immobilized in a matrix are operating in series and in a counter current mode. After passing a suitable volume of feed, a filter unit from the first series of filter units is disconnected at a particular position number, and an additional filter unit is connected at another particular position number herewith obtaining a next series of filter units where over the passing of a next volume of feed is continued. This process overcomes the problem of loss of yield of the purified compound as occurs during conventional activated carbon treatment.</p> |
