Chemical equilibrium is a major factor in many natural and
industrial systems. The ability to predict ionic equilibrium is
extremely valuable in industry in solving problems without the costs
involved in full scale experiments. An example of an application in
the pulp and paper industry is the prediction of non-process...
Hydrogen sulfide emissions from the smelt dissolving tank area
of some kraft pulp mills exceed environmental limitations. There are
two main factors to consider in determining the cause of these emissions:
chemical equilibria and rate processes. This investigation
considers the chemical equilibria in the smelt shatter jet area (system
A)...
The non-ideal aqueous electrolyte simulator (NAELS) is composed of
three major parts: a Newton-Raphson non-linear optimization program written
by Weare, et al (1987); an activity coefficient subroutine for non-ideal
electrolyte systems based on Pitzer's model; and an extensive, user expandable
database. It is robust, stable, and requires neither thermodynamic data...
In particle induced desorption-ionization mass spectrometry the strength of an
analyte's signal under a given set of bombardment conditions is usually considered to
be representative of the analytes relative surface activity. This rationale is generally
used to explain differences in the technique's sensitivity between and within various
classes of compound....
