<p>A liquid is applied to a horizontal spreader plate (2) which extends towards, and forms a narrow gap (50) with, the vertical walls of a gas diffusion apparatus. The liquid spreads out in a thin film across the spreader plate, fills the plate/wall gap and flows down along the container walls (10) and exits the container at the container bottom. The film on the container walls is sufficiently thin that when the container is filled with gas, gaseous diffusion into the liquid is greatly enhanced.</p> |
