(Energy Conservation I) Steam Conservation Adaptive to Operating Conditions

As shown in the lower right diagram, the solvent reaches a breakthrough state as the adsorption capacity gets saturated.
Hence, the correct exhaust concentration of each adsorption tower is detected by the concentration detector as in the upper right diagram to launch an automatic transition from adsorption to desorption, thereby assuring maximum activated charcoal adsorption utilization to reduce the number of runs of desorption/adsorption required to a minimum.

The exhaust gas concentration system not only saves steam requirements but also greatly aids as a pollution control facility in detecting failures in their early stages of occurrence and checking activated carbon performance.

Where multiple gas sources exist, the raw gas load counter system counts the load at the inlet of the recovery equipment from signals representative of their respective operating conditions and switches from adsorption to desorption automatically when the inlet load reaches the maximum adsorption load for one tower.
The number of runs of desorption/adsorption required is thus always kept minimal as with the exhaust gas concentration detection system. Signals (pulses) proportionate to varying gas sources are transmitted to ensure that the raw gas loads will be counted as correctly as possible.

The raw gas concentration system detects the concentration and flowrate of the solvent generated and counts the volume of the solvent at the inlet of the recovery, switching from adsorption to desorption automatically when the inlet volume reaches the maximum adsorption load for one tower.
The number of runs of desorption/adsorption required is thus always kept minimal.
The system is characterized by its ability to determine the inlet loads correctly even where loads arising from a single source or multiple sources vary widely or frequently.
