Case study demonstrating how a complete solvent changeout was accomplished in an accelerated time frame with coordination between the operating company, solvent supplier, and distributor.
Use of CFD Modeling to Optimize Capital and Operational Costs of Molecular Sieve Units
Sandeep Jain and Nicole Sing - Arkema
CFD analysis and real industrial cases are used to evaluate the adsorption and regeneration phases of molecular sieve designs, bed configurations, and troubleshooting issues.
Using Welded Plate Heat Exchangers to Improve Process Economics
Robert Broad and Peter Kauders - GESMEX GmbH
The use of compact heat exchangers to optimise gas plant design and operation. Holistic thinking and some innovative mathematical modelling assist in their evaluation.
HySWEET: Sour Gas Processing Reinvented!
Renaud Cadours, Claire Weiss, and Eric Cloarec - Total
A new generation of hybrid solvents has been developed. The process robustness, its operability and the easy implementation in existing units provides significant benefits.
Dealing with Sour Natural Gas Liquids in Gas Processing Plants
Saeid Mokhatab, Scott Northrop, and William Echt - ExxonMobil
The most commonly used treating methods to produce marketable hydrocarbon liquid products are discussed including developments that have taken place over the last few years.
Liquids Recovery— A New Concept for an Old Scrubber
Ankur Jariwala, Dag Kvamsdal, and Pinkesh Sanghani - Schlumberger
The old scrubbers are not efficient to recover and remove NGL due to the limitation of separation internals. One such site in South East Asia was losing significant amount of NGL in the downstream pipeline due to separation internals bottleneck. A new Axial cyclonic Inlet device allows to recover 99% of the liquids in the separator. We present details of the test program, discuss the importance of using real fluids for verification of scrubber performance, and present test results verifying the liquid carryover before and after implementation of the new inlet section.
Amine Systems: Impact of Solids on the Corrosion - Fouling Cycle and Concentration Cell Corrosion
Robert H. James and Ali Arshad - Pall Corporation
Amine system corrosion issues and minimization strategies are reviewed. Quantified solids reduction recommendations are made to reduce corrosion-fouling cycle and concentration cell corrosion losses.
Process intensification of upstream gas separations through adsorption-based technology
Ananda Krishna Nagavarapu, Justin Federici, Tracy Fowler, William Barnes, and Phillip Schoch - ExxonMobil Upstream Research Company
A novel adsorption-based gas separation technology platform being advanced by ExxonMobil is presented here. Deep dehydration and CO2 removal for cryogenic applications are discussed.
Perils of Foaming and Too Much Antifoam in Amine Treatment
John S. Sczesny and Al Keller - MPR Services
Froth formation on trays and in reboilers becomes a problem when contaminants allow a large volume of the liquid fed to an absorber or regenerator to be incorporated into an integrated bubble structure, foam. Best practices for contaminant prevention, removal, and application of anti-foam agents is discussed.
Installation of liquid sulfur degassing processes in existing SRUs
Marco Van Son, Shashank Gujale, and Rien Van Grinsven - Jacobs Canada, Inc.
This paper describes the importance of degassing and compares different options to install liquid sulfur degassing in existing plants with minimum impact on operations.
Improving your bottom line -Thermal Incinerator Optimization
Ryan T. McLennan, Inshan Mohammed, and Dharmesh Patel - Sulphur Recovery Engineering (SRE)
Three case studies demonstrate how significant reductions in fuel gas requirements can translate into cost savings for the operating company while maintaining environmental compliance.
Fluid Quality Management on Amine Systems: A Case Study
Matt Thundyil - Transcend Soltutions, LLC
Contamination in amine systems is endemic, and affects treating capacities, operating costs and reliability. Following extensive analytical work, many media configurations were evaluated resulting in a 10X reduction in change-out frequency, and 70%+ cost reduction, while improving the amine quality. We discuss the analytical techniques, testing program, and best-practices finding.
An assessment of hydrogen sulfide stability in samples of aqueous N-methyl diethanolamine solutions
Clare Worley, Allen Day, and Jeffery Johnson - Dow Oil, Gas and Mining
Where did my H2S go? This paper explains what happens to your amine samples between the plant and the lab.
Desulfurization of amine acid gas under turn down: Performance of the biological desulfurization process
Jan Klok; Gijs Van Heeringen, and Phillip Shaunfield - Paqell
This paper discusses the operation of the biodesulfurization unit of XTO Energy’s East Texas natural gas operations in turn down (<16%), treating amine off gas.
Tube Fouling and the Effects on Waste Heat Boiler Tube Wall Temperature
Steven M. Fulk, Clayton Jones, Simon Weiland, and Matthew D. Bailey - Optimized Gas Treating
This paper uses a state-of-the-art SRU simulator to show how the tube wall temperature exceeds 600oF under some fouling scenarios and the resulting sulfidic corrosion impact on tube life and life cycle cost.
