Abstract:
1. A method of operating a rotary valve for a liquid adsorption process, the rotary valve comprising a stationary track plate and a moving rotor plate, the stationary track plate having a plurality of annular tracks, the method comprising: selecting a seating force; measuring a pressure in each annular track in the stationary track plate at a first position of a plurality of positions of the rotor plate; controlling a pressure on a seal sheet at the first position based on the measured pressure at the first position and the seating force; indexing the rotor plate to a next position of the plurality of positions of the rotor plate; measuring a pressure in each annular track in the stationary track plate at the next position; controlling the pressure on the seal sheet at the next position based on the measured pressure at the next position and the seating force.
