The talk will highlight the evolution of Mixed Matrix Membranes (MMM), developed in the mid-1980s. The talk will first provide an introduction into the strategic thinking that led to the development of the water stable adsorbent ADS-200. ADS-200 is a cellulose acetate bound zeolite used in the...

A comprehensive first-principles based mathematical model, which explicitly accounts for membrane hydraulic permeability, pump characteristic curves and retentate pressure drop, is developed to describe the reverse osmosis desalination process. Parameters used in the model are derived from data...

This talk will describe our recent progress in the synthesis and processing of MOF/ZIF materials for molecular separation applications, and their subsequent use in the fabrication of membrane/thin film devices for such uses. New separations technology is key to increased energy efficiency in the...

The LNG industry, if not the entire energy industry, may be at a crossroad. Expectation of large shale gas supplies in the United States, with a backdrop of international economies in precarious states, makes more uncertain the promise of major investments in LNG import facilities. Already, a...

Accurate measurements of skin temperature on cracking furnace coils have become necessary for improved process control. Infrared devices have proven inaccurate for measuring skin temperatures on furnace coils. The inaccuracy has been driven in large part by an uncharacterized and misunderstood...

The process safety management in an industrial plant is a critical success factor for companies integrated in a global market. The equipments should have maximized performance and operational runlenght without compromising process safety. The challenge for excellence performance drives companies to...

Hydrogen is a critical component in the production of cleaner fuels. Underground pipelines provide a safe, reliable supply of hydrogen to refineries and the petroleum industry. Proper assessment of the risks associated with underground hydrogen pipelines requires an accurate model of the jet fire...

The Dow Hydrocarbons Business has a thorough process for managing excellent EHS performance during Turnarounds. We name an EHS Focal Point for each Turnaround 2 years in advance. A Turnaround EHS Preparation and Execution plan is developed and followed. An EHS Readiness Assessment is conducted with...

A new separation technology, called stripping crystallization (SC) or distillative freezing (DF), has been recently developed in our laboratory to separate the mixtures with close boiling temperatures, including the mixed xylenes [1-3] and the benzene/cyclohexane mixture [4]. In principle, SC is...

Catastrophic incident root causes often may be correlated with power outages. An unanticipated power outage may be an initiating event that leads to a process upset or even an emergency shutdown of a process unit. If the planning and implementation of the emergency shutdown are managed incorrectly...
