Dynamic operability assessment : a mathematical programming approach based on Q-parametrization
The ability of a process plant to guarantee high product quality, in terms of low variability, is emerging as a defining feature when distinguishing between alternative suppliers. The extent to which this can be achieved is termed a plant's dynamic operability and is a function of both the plant …

Biochemical Characterization of the Activity and Specificity of ULP1 Family Members
… proteins. Conjugation machinery charges the processed-SUMO so that it can be linked via an isopeptide bond to a target protein. The removal of SUMO moieties from conjugated proteins by isopeptidases regenerates pools of processed-SUMOs and unmodified target proteins. Yeast Ulp1 is the …

Developing a methodology for reducing diamond breakage within processing plant
… Ceramic diamond simulants have been used in the process to identify areas that are more prevalent to diamond breakage. It was found that sections of high impact such as the cone crushers and drop height in the surge bins had the highest risk of diamond breakage. Kimberlite ore and ceramic diamond …

Performance assessment of multivariate control systems
Modern process plants and refineries contain hundreds to thousands of loops under automatic controls. Poorly performing control loops cause off-spec product, waste energy, and cause maintenance and safety issues. Much of the process control engineer's time is spent finding the root cause of poor …
