Difference among ASTM D6228 , ASTM D5623 , ASTM D1266 in LPG Testing

ASTM D 6228: (WE RECOMMEND THIS METHOD)

This test method covers the determination of individual volatile sulfur-containing compounds in gaseous fuels by gas chromatography (GC) with flame photometric detection (FPD). The detection range for sulfur compounds is from 20 to 20 000 picograms (pg) of sulfur. This is equivalent to 0.02 to 20 mg/m3 or 0.014 to 14 ppmv of sulfur based upon the analysis of a 1-mL sample.
This test method does not intend to identify all individual sulfur species. Total sulfur content of samples can be estimated from the total of the individual compounds determined. Unknown compounds are calculated as monosulfur containing compounds.

ASTM D 5623

This test method covers the determination of volatile sulfur-containing compounds in light petroleum liquids. This test method is applicable to distillates, gasoline motor fuels (including those containing oxygenates) and other petroleum liquids with a final boiling point of approximately 230°C (450°F) or lower at atmospheric pressure. The applicable concentration range will vary to some extent depending on the nature of the sample and the instrumentation used; however, in most cases, the test method is applicable to the determination of individual sulfur species at levels of 0.1 to 100 mg/kg.

ASTM D 1266 (Lamp Method)

This test method covers the determination of total sulfur in liquid petroleum products in concentrations from 0.01 to 0.4 mass % . A special sulfate analysis procedure that permits the determination of sulfur in concentrations as low as 5 mg/kg.

Global Oil and Gas Market Update Dec, 2013

 GCC Oil and gas consumption set to rise 50 per cent by 2030.
 Global gas flaring has been reduced by 20 per cent over the past six years, helping to reduce
wastage of the energy resource and a drop in global CO2 emissions
 Chevron Corp.’s $1.4 billion base oil plant comes on line at the Pascagoula refinery next year.
 Germany consumed 79553 MT of Lubricants in August 2013.
 Heritage‐Crystal Clean, Inc. Announces the Acquisition of Used Oil Collection Service Territories
in the Great Lakes Region Rea.
 Seaoil introduces reformulated fuels with STP additives.
 Illinois ethanol plant to build co‐located biodiesel plant.
 West Asia demand may drive basmati exports to record 4 mt.
 Soyameal exports jump nearly four‐fold to 1.94 LT in October.

Japan Oil and Gas Market Update Dec, 2013

 Japan Oil and Gas Markets Outlook to 2025 provides comprehensive analysis and forecasts of
the Japan oil and gas market between 2000 and 2025. Covering the entire value chain of the industry,
the report analyzes each of the oil and gas segments in Japan including upstream sector, pipeline,
refinery, LNG and storage sectors. Further, detailed information on new fields, blocks, pipelines,
refineries, storage assets and LNG terminals along with the investments required, current status of the
projects and commencement feasibility are provided, highlighting the growth potential and feasibility of
projects.
 Japanese firm, Seychelles to conduct joint surveys for oil, gas.

Russia Oil and Gas Market Update Dec, 2013

 Ukraine builds plant for recycling used oil.
 Top Russian oil firm Rosneft said it would sell about $6 billion worth of refined products to BP,
establishing the British major among its biggest buyers after years without any such deal.
 The latest transaction comes on top of a $5.3 billion deal for BP to buy crude, agreed earlier this
year. Both came only months after Rosneft hired a former senior BP trader, Marcus Cooper, as head of
its own trading arm in Geneva.
 BP has become Rosneft’s second‐largest shareholder, behind only the Kremlin, after Rosneft
took over BP’s Russian venture TNK‐BP for $55 billion in March.
 But the participation in Rosneft’s ownership was slow to translate into cooperation in upstream
projects, while Exxon Mobil signed a flurry of deals with Rosneft to tap the Russian Arctic together.
 BP has also been absent for many years from the list of major buyers of Rosneft’s oil and refined
products, while rivals such as Shell have been among the biggest players in taking oil exports from the
world’s largest producer.
 Over the past year, Rosneft also has sold large amounts of crude to trading houses Glencore,
Vitol and Trafigura as they have lined up $11.5 billion worth of pre‐payment, which helped Rosneft ease
the burden on its balance sheet.
 Cooper took over trading operations at Rosneft’s Geneva office after years at BP, including a
senior position at its office in Singapore.
