Estimate healing and cooling times for batch reactors
Article Abstract:
The heating and cooling times of batch reactors equipped with single-fluid utility systems can be determined through several equations. The latter can also be used in solving heat-transfer problems at steady-state conditions. Maximum heat-transfer rates and jacket inlet and outlet temperatures can be computed directly without resorting to trial-and-error methods. The equations can be used under constant values of utility supply temperature, heat-transfer coefficients, utility and circulation flow rates, heat capacities. Heat losses should also be negligible while no phase changes should occur.

Take the tedium out of writing process descriptions
Article Abstract:
The SAY function of writing detailed chemical process descriptions is described. The SAY uses a single letter for abbreviating a whole word or phrase while no letter is repeated within a set of objects, or a set of verbs. This procedure will allow process descriptions to be generated quicker and be more understable. The descriptions are also consistent in both wording and style and are easy to update. They are also compliant with the company's instrumentation standards.

Apply solubility theory for process improvements
Article Abstract:
The basics of solubility theory and it's applicability to process improvement are reviewed. Examples which explain the solubility theory for non-electrolytes show that the entire solubility curve can be obtained by the use of a very minimal amount of data like melting point, heat of fusion and a single solubility data point.
