Scrubber Design For Phosphoric Acid Production Facility, Edward E. Mayer Apr 1979

Scrubber Design For Phosphoric Acid Production Facility, Edward E. Mayer

Retrospective Theses and Dissertations

This report is an examination of the practical design of a phosphoric acid production facility wet scrubber. It includes a brief background of the Florida Phosphate Industry, in addition to the rules and regulations affecting the emission of fluoride contaminates. The theoretical aspects of a packed absorption tower is discussed prior to the actual design of a cross-flow wet scrubber of the type typically found in the Florida Phosphate Industry.


Effects Of High Altitude Jet Aircraft On The Stratosphere, Dennis K. Bushnell Jul 1973

Effects Of High Altitude Jet Aircraft On The Stratosphere, Dennis K. Bushnell

Retrospective Theses and Dissertations

This paper presents a review of the basic thermal, chemical and radiation balances existing in the atmosphere and discusses the mechanisms by which jet engine exhaust products can disturb these balances. Possible effects of stratospheric pollution on plant and animal life are discussed. Methods for reducing harmful emissions through engine design modifications are outlined and current successful research programs are surveyed. The SST type aircraft is shown to be a greater threat to the environment than conventional jets because of differences in cruise altitudes. It is concluded that due to the existence of several potential environmental problems associated with contamination …
