Fouling Mitigation Program Recovers Operating Efficiency and Extends Run Length for Ethylene Plant Oil Quench Tower

Mar 16, 2011

Mike Hong

Extension of system run length and maximizing plant throughput will bring substantial profit to olefin producers. The fouling problem in the oil quench tower of the ethylene plant, however, has become a challenge to achieving long run length goals and has even led to unscheduled shutdown or reduced...

Improved Ethylene Cracking Furnace Control with Modern Process Mass Spectrometers

Mar 16, 2011

Peter J. Traynor

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...

Enhanced Heat Transfer Technology Proves Beneficial In Cooling Water Driven Condensers

Mar 16, 2011

Michael R. Sobczyk

Cooling water driven condensers utilizing enhanced heat transfer technology deliver technical and economic advantages in both revamp and grassroots applications. Meeting equipment performance demands within the confinement of an existing unit structure can be accomplished with simple tube bundle or...

Loss of Downcomer Seal on a Depropanizer During a Plant Start up

Mar 16, 2011

Andre Bernard

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...

A New Class of Polymer Inhibitors

Mar 16, 2011

P. N. Ramaswamy

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...

Critical FLNG Project Enablers: Identified Risks and Mitigation

Mar 15, 2011

Joseph H. Cho

Energy demand in the next two decades is expected to increase by 50 percent or more driven by the engine of economic growth. In parallel, the global demand for natural gas is anticipated to grow faster than the overall demand for liquid and fossil fuels. Economical monetization of stranded reserves...

Mitigation of Preheat Fouling by Eliminating the Cause

Mar 15, 2011

Irv Wiehe

Today, there is no excuse for not getting five years or more on the run length of refinery preheat exchangers without the need for cleaning. Among the many tools available for fouling mitigation of preheat exchangers, the most overlooked ones involve determining and eliminating the cause. Almost...

Enhance Cracked Gas Compressor Reliability with Novel Antifoulant Technology

Mar 15, 2011

P. N. Ramaswamy

Enhance Cracked Gas Compressor Reliability with Novel Antifoulant Technology It is widely known that there is a potential for fouling in Cracked Gas Compressors within Ethylene plants. Gas crackers have generally had a higher fouling potential than liquid crackers due to the lack of aromatic...

Complimentary Theoretical and Experimental Studies: CO2 Capture with Supported Ionic Liquid Membrane

Mar 15, 2011

David Luebke

Researchers at NETL have examined techniques for the capture of CO 2 using supported ionic liquids membranes. In this talk, we will show recent molecular simulation and experimental results involving separation of mixtures of CO 2 and H 2 using ionic liquids membranes. Specifically, we will show...
