The effects of possible operating variables such as flow rate, surface temperature, bulk temperature, solids contents, sulfate addition and pH on the fouling of sulfite spent evaporators were studied. The study pointed out that the Ca⁺⁺ concentration difference between heated surface and bulk is the most important factor for fouling...
The infrared spectra of the metaborate monomer and trimer
ions in NaC1, KC1, and KBr were studied. These spectra contain
bands due to the trimer in solid solution, in a second phase of the appropriate
potassium or sodium salt, and perhaps on adjacent lattice
sites. Furthermore, complex equilibria exist between...
The source and nature of permit value and the federal grazing fee debate motivated this dissertation research. There is little doubt that federal grazing permits have value throughout the western United States, but the source of permit value is unclear. A traditional explanation focuses on the capitalized differential between the...
Non-process elements are present in all kraft
recovery systems. Non-process elements are defined as
those elements which are not essential to the chemical
process, i.e., are neither active pulping chemicals (e.g.,
NaOH and Na₂S in the kraft process), nor compounds present
as a result of incomplete conversion of makeup chemicals...
Black liquor recovery boilers experience significant fire-side fouling problems due to the deposition of entrained particulate matter. Increased understanding of the mechanisms by which particles deposit on these surfaces will lead to more effective management of the resultant problems. There is some evidence which suggests that the sub-micron fraction of...
The major objective of this study was to seek the reactions
of a group of supermarket managers as to what factors they felt were
necessary to a successful performance in their occupation.
One hundred eighty-four managers employed by a western-based
firm which operates stores in ten states returned questionnaires
rating...
