Correlating Process Safety Indicators with Performance Jerry Forest Global Process Safety Manager Celanese 1601 West LBJ Freeway Dallas, TX 75234 (214) 417-1920 Jerry.forest@celanese.com Abstract By definition, process safety leading indicators are predictive in nature and therefore should have a...

Dissolved Oxygen Content Measurement in Aqueous and Hydrocarbon Liquids

Apr 3, 2012
Feridoun Fahiminia
Dissolved oxygen in aqueous and organic liquids affects a variety of process operations. Even at trace levels, it can lead to fouling in processing units such as separators, heat exchangers, pumps, compressors, and reactors, causing unplanned shutdowns. It can also promote corrosion in processing...

Root Cause Study of Debutanizer Column Operational Upsets

Towards Inherently Safer Processes: Alkylation of Isobutane and n-Butene

Apr 3, 2012
Subramanya Nayak
The alkylation production first started in the late 1930s and early 1940s with collaborative efforts by several American companies. Currently, 13 – 15 % of the refined gasoline pool is made up of these C8 alkylates (Albright, 2003). In this study, we have evaluated if it is possible to develop...

Relief Design for Laboratories and Pilot Plants

Apr 3, 2012
Jennifer Mize
Relief evaluation and system design for laboratories and pilot plants presents unique challenges to the relief designer. Relief devices designed for commercial production-sized process vessels are often impractical for use in laboratory and pilot plant environments due to their size. However,...

Carbon Capture Ready Heavy Oil Extraction and Upgrading

Apr 3, 2012
Eloy Flores
Carbon dioxide emissions from heavy oil production are typically higher than that of producing conventional crudes. Ultimately, carbon dioxide emissions can make heavy oil production less competitive if regulated. Carbon dioxide emission regulations will affect the overall economics of heavy oil...

G. T. Polley
Practical Process Integration Retrofit Part 3. Path Analysis G.T.Polley The concept of transferring heat along paths was first suggested by Dhole [1]. It was subsequently investigated by Adiarso [2] and Van Reisen [3,4]. It forms the basis of a technique known as Network Pinch introduced by Zhu...

The Benefits of a Risk-Based Approach to Facility Siting

Apr 3, 2012
Neil Prophet
Facility Siting has come under increasing scrutiny in recent years, and is an important aspect of process safety for plant personnel and their contractors. In December 2009, API issued the Third Edition of the facility siting Recommended Practice 752, “Management of Hazards Associated with Location...
