Engineers faced with a crystallization problem are likely to seek data on the solubilities of the substances involved. However, solid-fluid equilibrium (SFE) phase diagrams offer advantages that cannot be gained from solubility data alone. This article provides a detailed discussion of how to best use SFE phase diagrams, particularly for multicomponent mixtures.

Factoring in emissions during boiler design and operation.It used to be that boiler systems were designed with a keen eye toward maximizing efficiency and minimizing capital and operating costs. Increasingly, air-emissions requirements are imposing real constraints during the design and operation of gas and oil-fired boilers.

Most engineers are familiar and comfortable with equations that correlate data. But all would be well-advised to remember that every correlation has its limitations. During a calculation, the flame temperatures of several gases were found to be suspect beyond the range of the heat-capacity correlations used in the calculations. Take a journey with this author, as he routes out the mathematical discrepancies and stakes out an alternate route to solving the original problem.

When using data correlations, make sure they fit. This flame-temperature calculation illustrates a common problem: Engineers found that the data would not converge because of an inadvertent extrapolation.

A host of field-screening methodologies including immunoassay and turbidimetric techniques, field-hardened infrared spectroscopy and gas chromatography, and the use of organic vapor analyzers are readily available to help engineers characterize petroleum-based releases during site remediation. This article discusses the pros and cons of each. Screening tools speed site clanup.
