Photochemical reactions are usually of first order, suggesting the use of a continuous plug flow reactor for minimizing reactor volume and energy requirements. The limited radiation penetration depth applied in photochemical reactions, however, requires intensive radial mixing, which is lacking in a plug flow reactor. This may be resolved by using a cascade reactor, which combines low mixing in the flow direction with intensive mixing in the radial direction.
