Acid gas compounds are removed from a process gas such as, for example, syngas or natural gas, by flowing a feed gas into a desulfurization unit to remove a substantial fraction of sulfur compounds from the feed gas and flowing the resulting desulfurized gas into a COremoval unit to remove a substantial fraction of COfrom the desulfurized gas.

Disclosed is an optimized process and apparatus for more efficiently and economically carrying out the liquid-phase oxidation of an oxidizable compound. Such liquid-phase oxidation is carried out in a bubble column reactor that provides for a highly efficient reaction at relatively low temperatures. When the oxidized compound is para-xylene and the product from the oxidation reaction is crude terephthalic acid (CTA), such CTA product can be purified and separated by more economical techniques than could be employed if the CTA were formed by a conventional high-temperature oxidation process.

Method of removing paper wraps that are secured by thermoplastic adhesive around and/or to waste cigarette filter rods to enable subsequent recovery of the filter material in the cigarette filter rods, the method including the step of heating the cigarette filter rods to the melting point of the thermoplastic adhesive and then agitating the paper wrap against the filter material to obtain separation of the paper wrap therefrom.
