ASTM International Petroleum Products, Liquid Fuels, and Lubricants Committee Presents Top Annual Award to Dr. Andy L. Pickard


ASTM International’s committee on Petroleum Products, Liquid Fuels, and Lubricants (D02) will present its top annual award – the Award of Merit – to Dr. Andy L. Pickard, consultant in Qualicum Beach, British Columbia, Canada. The prestigious award, which includes the accompanying title of fellow, is ASTM’s highest recognition for individual contributions to developing standards.


The committee is honoring Pickard for his dedication and knowledge of standard specifications, classifications, and test methods within committee D02. He has been a member of ASTM International since 1983, and has won the Frank W. Reinhart Award (2015), the Eagle Award (2014), the Award of Excellence (2011-2013), the George V. Dyroff Award of Honorary Committee D02 Membership (2009), and the Award of Appreciation (2006), all presented by committee D02.


Previously, Pickard was a Senior Fuels Specialist of Petro-Canada until 2003. Aside from ASTM, he is a member of the Canadian Society for Chemistry, Association of the Chemical Profession of British Columbia, and Society of Automotive Engineers International.

Mercury and Petrochemicals P S Analytical – Experience, Performance, Reliability and Support


For over 30 years P S Analytical (PSA) has been at the forefront of trace mercury (Hg) determinations from petrochemical samples. It has never been more important to understand the fate of Hg in all aspects of oil and gas exploration, refining and production. The corrosive nature of Hg reacting with aluminium; the fate of Hg within a process itself; the concentration of Hg in feedstock’s that could destroy expensive


catalysts; as well as the OH&S concerns that Hg poses are, of course, well documented and are often a key driver in operational decisions. For these reasons much effort is spent on Hg removal technology and PSA partners with many companies to monitor and help manage this Hg removal process. This partnership happens from the research bench through to production with PSA taking a pivotal role in ensuring successful removal technologies are deployed in the real world.


PSA have analysers to suit all aspects of the monitoring and analysis of Hg, including laboratory instruments and on-line analysers for gases and liquids. More recently PSA have provided solutions for speciation (fractionation) analysis and also waste water systems associated with petrochemical processes.


Employing Atomic Fluorescence as a means of detection the PSA analysers provide ultimate detection performance. With literally thousands of systems in the field today, and support networks in Europe, USA and SE Asia, PSA offers the ideal package of performance, reliability and support.

High-pressure Foam Analysis Offers Targeted Enhancement of Foam-aided Methods for Oil Production


KRÜSS GmbH’s new High Pressure Foam Analyser – HPFA is the world’s first measuring instrument for the simultaneous capture of foam height and structure under high pressure. The HPFA is intended primarily for the tertiary oil production sector, where foams boost the efficiency of flooding procedures using gases such as carbon dioxide or nitrogen. The foam improves flow control, so that the oil can be extracted efficiently from the rock. The foams used must remain stable for a long period under the high pressure of the reservoirs and also withstand strong deformations during flows through porous rock. So the structure of the foam lamellae and the decay dynamics at high pressure are extremely relevant for the efficiency of the process.


The HPFA is equipped with high-resolution cameras that capture the foam volume and a video image of the foam lamellae in parallel during and after foaming. With the aid of the ADVANCE software’s real-time image evaluation the instrument measures the foamability and foam decay as well as changes in the absolute bubble size and its statistical distribution. The HPFA’s measuring cell operates at pressures up to 350 bar and temperatures up to 120 °C. During the analysis sensors permanently transmit measured values for pressure and temperature to the software.


The repeatability of foam formation is ensured by a filter through which the gas flows into the liquid under pressure. Variable filters with different pore sizes simulate the characteristic porosity of the respective rock and enable the modelling of foams with different bubble sizes.


When using the foam in the recovery process the aqueous foam in the reservoir often comes up against the foam inhibiting oil. This can trigger undesired foam decay. To date it has not been possible to test this effect under reservoir conditions. To make this possible, the HPFA comes equipped with a novel dosing unit that enables the dosing of any kind of liquid under pressure during the ongoing foam analysis.

Control of Hydrocarbon Refining Near-Infrared Spectroscopy (NIRS) enables straightforward multi-parameter analysis of critical parameters for monitoring the refining of hydrocarbons. NIRS is a non-destructive secondary analysis method, NIRS does not require any handling of chemicals whatsoever, and real time measurements are performed at the push of a button.

NIRS is the ideal method for a wide range of applications including:


distillation of crude oil: API Gravity, Reid Vapor Pressure (RVP), density, PIANO, lubricant oils: aromatics content, density, flame point, oil content, PAH, pourpoint, distillation analysis,


viscosity and diesel blends: cetan index, cloudpoint, density, FAME, colour, flashpoint, etc.
