Asia responds to oil's fluctuations
Ng Weng Hoong, Contributing Editor, surveys the different responses by Asian countries to the volatility in the oil markets.

Sulfur, so good
Harry Z. Ha, Patrick J. Stang and David B. Mercer, Fluor Canada Ltd, Canada, discuss sulfur species distribution and modelling in the gasoline desulfurisation process.

Defying convention
Technological advancements have the potential to offer gas processors faster execution, more reliable operation, and improved profitability. Eric Sallee, Honeywell UOP Russell, USA, outlines the benefits of pre-engineered and digitally connected plants.

Every last drop
Wiley Rhodes, Newpoint Gas, USA, introduces an end-to-end business model to monetise stranded flare gas and all hydrocarbon emissions.

Amine regenerator control: part one
Pedro L. Ott, Nathan A. Hatcher and Ralph H. Weiland, Optimized Gas Treating Inc., USA, explore where to locate temperature sensors in an amine regenerator.

Modern methods
Izak Nieuwoudt and Patrick Quotson, Koch-Glitsch, alongside Juan Juarez and Norman Yeh, ExxonMobil Upstream Research Co., USA, explain how modern random packing technology helps to improve tower performance.

Mirror, mirror on the wall
S. V. Seleznev, G. A. Derevyagin and A. M. Derevyagin, SPA Vympel LLC, Russia, alongside M. Chwal and P. C. Lyon, Vympel GmbH, Germany, discuss advances in the calibration of hydrocarbon dew point analysers.

The search for dry gas
John Kerney, AMETEK Process Instruments, USA, explores a variety of moisture measurement technologies for natural gas dehydration.

Lasers in safety
Rhys Jenkins, Servomex, UK, examines the suitability of using tunable diode lasers for safety monitoring in combustion within hydrocarbon processing applications.

Predictive ethylene production
Gregory Shahnovsky, Ariel Kigel and Ronny McMurray, Modcon Systems, UK, explore a method of ethylene cracking to increase profit.

Accurate analysis
Tony Wimpenny, Orbital Gas Systems, UK, describes the combination and optimisation of two technologies to produce a solution for continuous, accurate measurement of LNG quality.

An evolutionary approach
Mark Roberts, Dr. Justin Bukowski, and Janet Mitchell, Air Products and Chemicals Inc., USA, explore liquefaction cycles for floating LNG from concept to reality.

Making good use of boil-off gas
Holger Tewes and Sven Strache, MAN Energy Solutions, Germany, detail the waste-saving advantages of using screw compressors in low-temperature applications.

Pushing the limits of compression
Harry Miller and James Sorokes, Siemens, USA, explain why generalised rules of thumb should be avoided when selecting equipment to compress lower molecular weight gases.

Saving energy with VSD systems
Freddy Gyllensten and Alessandro Castagnini, ABB Motors and Generators, outline how variable speed drive (VSD) systems and synchronous motor technologies can provide significant energy savings in the petroleum and chemical industries.

Self-regulating and safe
Frank Bungartz, Bungartz, Germany, introduces self-regulating non-priming pumps for use in the petrochemical industry.

Up to standard
Chad Wunderlich, Viking Pump, USA, explains why it is important that rotary positive displacement pumps meet the latest industry standards.
