Abstract

The performance of a spiral wound element, i.e. permeate flow and quality can be calculated by numerical integration of balance equations. The same is valid for the calculation of optimal element geometry. For this a computer program is required which needs reliable input data regarding geometrical parameters and transport characteristics. This paper presents some experimental data for pressure drop and mass-transfer characteristics in spiral wound elements and in spacer-filled flow channels. The experimental results and the computer program were used to calculate the performance of a spiral wound element and its possible design variations.
