Stricter environmental emissions regulations and increased processing of severe crude oil fractions is causing H2 demand to grow across the refining industry. Costs associated with new H2 plant construction have been escalating, so refiners are increasingly looking for low capital cost retrofit...

This session will develop a fundamental understanding of how cycle time variation in stages of a supply chain propagates into measures of overall cycle time. Application can be seen in supply chains and inside plants with batch processes. While the sources of variation are symmetrical and can be...

An energy stewardship program, aimed at driving energy efficiencies from no-cost operational improvements has been implemented with considerable success across the Valero refining system. Two years since commencement of the program roll out, energy use has been reduced by 5% and over $140 million...

New advancements in multivariable pressure transmitter technology allow you to improve your flow measurement practices. By better understanding these advancements, you will be better able to quantify and optimize installed performance, select the right combination of compensation for a specific...

Refineries have been installing low NOx equipment on their fired heaters in response to tighter environmental regulation. Low NOx burners minimize air ingress in locations other than directly at the burner, and internally recirculate flue gas in the heater firebox. They operate on much narrower...

This presentation will provide a summary of each of the primary environmental regulatory programs, including air, water, waste and emergency planning. These programs are also known by their statutory names, the Clean Air Act, Clean Water Act, Resource Conservation and Recovery Act and the Emergency...

Whereas process mass spectrometers have been used as an alternative (lower cost) solution to multiple process gas chromatograph installations for many years, their use has been somewhat limited by their complexity - both real and perceived. The latest generation of process mass spectrometers has...

The bottom C4’s product specification could not be met on the Depropanizer tower during a plant start up. The olefins unit had been started with a new start up procedure, which involved significant reduction in feed rates to the unit until achieving on spec ethylene. C3 & C4’s product were to...

Polymer inhibitors are used within an ethylene plant in locations which are susceptible to aggressive polymer formation i.e. Primary Fractionator, Compressors, Pyrolysis Gasoline Strippers and within the Gas Separation units. Over the years, the use of such additives has been extended to newer...
