Abstract
Abstract The invention is a multiple compartment horizontal cross flow packed bed absorber. A hollow shell has corrugated side walls and a corrugated bottom wall. A partition separates the shell into a front compartment and a central compartment. Each of the compartments contains suitable tower packing. A horizontally slotted inlet grill and a vertically slotted outlet grill are provided. A liquid distributor distributes liquid downwardly through the front compartment and the central compartment.
