(a)
Interpretation:
The KF and
Concept introduction:
The data as provided must be reasonably correlated by the Freundlich isotherm. The equation for the Freundlich isotherm is as follows:
(b)
Interpretation:
The time required for the breakthrough of NO2 needs to be determined.
Concept introduction:
The adsorption column has an internal diameter of 10 cm and a bed from a stream that has 1.0 mole % NO, the balanced air entering the absorber at 8 kg/h.
(c)
Interpretation:
The number of columns required to achieve the continuous process operation needs to be determined.
Concept introduction:
The silica gel in the column would be regenerated by the elevation of bed temperature and purged the bed with clean air. Given the regeneration process requires 1.5 hours to accomplish it all, the shutdowns can be stopped with the installation of various silica gel columns.
