Abstract
The dependence has been measured of the interfacial area and the number of transfer units for gas side resistance controlled absorption on the flow rate of gas and liquid at counter- and cocurrent flow arrangement. The measurements have been carried out for a vertical expanded metal sheet packing exhibiting a strong dependence of the interfacial area on the density of irrigation. The interfacial area has been measured by absorption of carbon dioxide into a solution of sodium hydroxide under the conditions of the pseudo first order reaction. The number of transfer units has been measured by absorption of sulphur dioxide also into a solution of sodium hydroxide. In addition, the pressure drop has been correlated against the flow rate of gas and liquid.
