COQA Director, Harry Giles, at

Please note that this is a NEW Email.
The Director will also provide an attendance roster, upon request. Legal Review of Anti-Trust - Harry Giles, COQA Facilitator, reminded all attendees to review the Standard Setting Rules prior to each meeting. The Standard Setting Rules can be found on coqa-inc.org under “Information”. Synthetic Crude Update · Fully hydrotreated bottomless crudes · Fully hydrotreated heavy crudes · Partially upgraded crudes (typically only the naphtha cut might be hydrotreated) o with or without bottoms · Synbits (bitumens diluted with a light synthetic crude) o Conventional Canadian heavies are “dilbits” (bitumens diluted with condensate) Distillation, sulfur, acidity, etc, will vary in any of these types of crudes dependent on the source of the oilsands and hydroprocessing techniques.

this Document**** Aaron Dillard continued the discussion with details on some of the specific synthetic grades available. Synthetic crudes are an emerging crude supply for North American refiners and, as such, are a good opportunity to help balance supply and demand. In many cases, suppliers can customize a blend to meet a refiner’s specific requirements. There are, however, issues to be addressed; as is the case in any new supply. Synthetic crudes act differently than crude oil. Predicting properties and behavior is more difficult when tried and true correlations do not necessarily apply. This has ramifications for processing and transporting. Existing LP models may need to be revised. Some synthetic crude contains cracked material which could be an issue for refining processing and pipeline interface. Pipeline interfaces may require extra attention, in addition to the normal care pipelines take for segregation of sweet / sour, high / low metals, heavy / light, etc. A sweet, light partially upgraded synthetic crude may still require buffering, for example, when traveling next to a sweet, light crude oil.

this Document**** SPR Crude Quality Initiatives The SPR is also currently involved in a
mercury study. Mercury is
becoming an area of environmental concern and, to date, there are not
reliable analytical techniques available for use by most laboratories.
Mercury can contribute to increased corrosion rates and emissions
can pose a severe health hazard. NIST,
a government agency, has developed a promising methodology for mercury
detection. The SPR is working
with NIST on a comprehensive study to define the mercury content of crude
oils refined in the Long term
storage facilities can have a unique set of issues.
However, detailed studies have confirmed that the long term storage
does not adversely affect the quality of the crude oil.
Elevated vapor pressure can be a problem but is minimized by
periodic degassing and the use of heat exchangers during drawdown.
Hydrogen sulfide may also need to be managed during drawdown and
tests are underway to determine the extent of possible hydrogen sulfide
emissions. The SPR enjoys a
long-term relationship with SPR QUALITY INITIATIVES - US DOE - View
this Document**** An Overview of Valero Energy Corporation was presented by John Mauer. Valero started out in the 1980’s in the natural gas industry and expanded into the refining business through building (their Corpus Christi refinery is one of the most complex refineries in the world) and acquisition (Gulf Coast Refineries from Basis Petroleum; Paulsboro, NJ from Mobil; Benicia, CA from ExxonMobil; Corpus Christi from El Paso; St. Charles from Orion). The natural gas assets were sold and Valero launched into retail marketing in the late 90’s and early 2000. In 2001, Valero acquired Ultramar Diamond Shamrock which included 6 refineries, interests in pipelines and terminals and additional retail sites. Today, Valero has more than 20,000 employees, revenue of $38 billion and total assets of $14 billion. Valero has a strong marketing presence with 4500 retail sites. Their 14 refineries have a combined throughput of more than 2 million BPD and can process substantial sour crude oil. Valero L.P. operates 4100 miles of pipelines, 18 refined product terminals and 8 crude oil storage facilities with over 14 million barrels capacity. Valero is committed to safety and the environment. Community involvement and treating employees well (no layoffs in the company history) is an integral part of Valero’s corporate culture. VALERO OPERATIONS - View
this Document**** Canadian Crude Quality
Initiatives
- Mr. Tim Blackmore of Omnicon Consultants represented the Canadian Crude
Quality Technical Association. ·
Phosphorous in crude continues to
be an active concern in many refineries.
A letter from sweet crude refiners calling for the removal of
phosphorous chemistries from sweet streams will be sent to the Canadian
Association of Petroleum Producers (CAPP). ·
The Heavy
Oil S&W Project is concentrating on sediment known to be a source of
refining problems. Work on
isolation and identification of unknown organic sediment is being delayed. · The new project on TAN is underway. The scope will include a review of testing procedures to determine the best method to use for TAN results in heavy oils and bitumen, studying TAN/NAN in individual cuts as compared to whole crude results and determining the predictability of TAN profiles while blending crudes. ·
The Tank
Cleaning Project is currently surveying refineries for best practices with
the goal of establishing a protocol for use by participating refineries
and pipelines to minimize the impacts of pipeline tank cleaning on
refinery operations. ·
The Alberta
Research Council has proposed a project on improving the measurement of
viscosity of heavy oils. Mr. Bill Lywood of Crude Quality,
Inc reported that CAPP will continue the crude quality monitoring program
for 2004 (CrudeMonitor.ca). Quality
assurance programs are in place to help ensure data confidence.
Also, CAPP is currently evaluating the possibility of incorporating
crude quality variance into the Incentive Toll Agreement with Enbridge
Pipeline. This program would
put a dollar value on prescribed quality with the producer, shipper and
carrier sharing in the cost and the incentive for success. Stream
consolidation continues to be discussed, with industry wide costs savings
expected through operating efficiencies and reduced capital costs. CANADIAN UPDATE - CRUDE QUALITY INC - View

this Document**** Report on the Communication Forum – The Education Forum for pipeline personnel is final. A pdf version will be posted on coqa-inc.org. Anyone wishing a copy in PowerPoint should please contact the COQA Director. A draft format of the crude oil quality training program for non-technical personnel is available for comment. The forum for refining personnel was discussed and will be ready in draft format at the next COQA meeting. Report from the COQA Steering Committee - A listing of websites that have crude quality data has been posted on coqa-inc.org. Data on crude oil quality incidents was collected at the general meeting and will be posted (in a consolidated, anonymous format) after legal review. COQA Web Site and Budget Report - The facilitator presented the final financial report for 2003 and the budget for 2004. Many thanks to our 2004 Financial Supporters:
Associate Members: BakerPetrolite, Giant Refining, ITS Caleb Brett,
