Using Pounds-Solids to Optimize Plant Efficiency

The first words in Dransfield’s book on “Engineering Systems and Automatic Control” are: “A machine or process is restrained to operate in a predetermined manner; that is, it is controlled. Restraint is usually achieved by controlling a selected physical variable vital to the performance of the particular machine.” It is the intent of this paper to propose pounds-solids as the variable, vital to the operation of a citrus processing plant. Contents of this paper describe a methodology for commercially measuring pounds-solids and using this information to optimize plant efficiency. Paper published with permission.

To Pump or Not to Pump? Heat Pump Strategies and Payoffs

After several evaluations of waste heat sources and designing heat pumps to recover energy, it has become very apparent that there is a great deal of confusion about just what makes a heat pump economic. The purpose of this article is to look into the design and economics of heat pump systems to determine what makes certain heat pump applications winners and others losers. Steam recompression and generation of steam from moist hot air are investigated specifically. Actual commercially available equipment is considered to determine the near-term and future economic viability of each approach as a function of the source and sink temperatures and magnitude of heat flow.
