Abstract

A distributor for distributing sulphuric acid on a packed tower. The distributor has an array of horizontal parallel distributing pipes in a single horizontal plane spanning a tower containing a packing and located above the packing. The pipes extend through the tower shell at one end and are accessible through a clean-out port at the other end. Feed enters the pipes at one end and the clean-out port at the other end permits cleaning without entering the tower. There are holes in the pipes arranged in a number of rows each angled downwardly. Each hole has a simple corrosion resistant insert to protect against hole erosion.
