Claire Cagnolatti
Comparative Performance Analysis™ (CPA™) benchmarking studies of the olefin industry have been conducted by HSB Solomon Associates LLC (Solomon) since 1987. This paper will highlight the results of a 16-year analysis of trends in turnaround performance by the industry. Data will be analyzed and...

The Rayleigh Equation Revisited What to Do When Alpha Isn't Constant

Apr 4, 2012
Robert G. Kunz
Abstract Integration of the Rayleigh Equation for batch distillation in closed analytical form has heretofore required that relative volatility (α) be assumed constant. A new technique presented in this paper produces a continuous analytical function for the Rayleigh Equation integral whether α is...

Tutorial on Hydroprocessing: ìHydroprocessing Catalysts and Processesî

Apr 4, 2012
Paul Robinson
The products of petroleum refining must meet tight specifications, including limits on sulfur, nitrogen, olefins, aromatics, and other contaminants. Hydrotreating removes these contaminants from distilled crude oil fractions and intermediate process streams. Hydrocracking converts heavy oil...

Evaluation of Dispersion Models for LNG Siting Applications

Apr 4, 2012
Andrew Kohout
The federal safety standards for LNG facilities under 49 CFR Part 193 approves the use of specific dispersion models for performing vapor-gas dispersion exclusion zones. In addition, provisions allow for the use of alternative models if approved by PHMSA. In 2010, PHMSA, in consultation with FERC,...

Evaluation of Reverse Osmosis - Electrode-ionization Pilot Project in PT Badak NGL

Apr 4, 2012
Fany Arfianto
PT Badak NGL utilizes groundwater for Plants and Community water consumption. Demineralization water production in PT Badak NGL uses ion exchange process which has high safety risk since it utilizes sulfuric acid and caustic for ion exchanger regeneration. The sulfuric acid sometimes leaks out from...
