The shown picture displays that setting of switching
periods of the valve was not precise enough and mea-sured composition of individual streams did not achieve
presumed values. An evaluation of all performed ex-periments confirms high requirements for precise unite
adjustment, namely to set the time-programmable
gearing of valve and maintain constant flow rates. Ob-tained results approve pertinence to process data im-mediately during the measurement and right away to
operate the separation process. This bears especially on
improvement of exact period for multi-functional valve
switching. It is also useful to equip the unit with a re-cycle to further improve the separation.
