Performance of absorption columns equipped with low pressure drops structured packings

During the past few years the industry has demanded structured packings wit h higher and higher efficiency and with lower and lower pressure drops. Usi ng these internals significant improvements were obtained in the absorption process but also in direct-contact heat transfer. In the present work a ne w type of packing is investigated both experimentally and theoretically to evaluate gas and liquid mass transfer coefficients, surface area available for mass transfer, and pressure drops. The experimental performances of the packing are tested in absorption and desorption systems to identify relati ons that allowing reliable design.
