Summary The meeting agenda (Attachment 1) was distributed to those in attendance (Attachment 2). There were 46 attendees of which 20 paid the attendance fee. Karl Fischer Water Measurement Methodology
- Ms. Rachael
Brooks of Brinkmann Instruments spoke on the various methods of water
determination in crude oil. Moisture
determination is important due to the economic ramifications for
suppliers, transporters, refineries and ultimate consumers.
Brinkmann Instruments recommends the Karl Fischer titration method
due to its fast analysis time, high degree of accuracy and precision, the
ease in sample handling and the relatively inexpensive equipment. There are two types of Karl Fischer tests, Volumetric and
Coulometric. The volumetric
method consists of metering in a reagent to react with water; the
cuolometric version generates the reagent that eventually mixes with the
water. Both methods are
accurate and almost full proof; there is very little room for operator
error. Sulfides and
mercaptans in the crude oil consume the titrant and can give high water
values. However, a masking
agent can be added to the solvent which will counteract the interference. Brinkmann Presentation

this Document****** Mr. Steve Stewart of KAM Controls also spoke on the
Karl Fischer measurement system. Water
measurement for custody transfer is especially challenging as the test
must be simple (field technicians have many different responsibilities), accurate (large dollars are involved) and repeatable (both
buyer and seller must be satisfied).
Crude oil itself is very complex and required modification of the
traditional KF analysis, especially considering the non-laboratory
environment in which custody transfer takes place.
However, many of the crude-specific requirements have been solved
with different reagents and portable equipment.
Per ASTM, Karl Fischer is currently the quickest and most
reproducible water measurement technology available.
With the world consuming 75 million barrels of oil a day, the
economic advantage of using Karl Fisher could be considerable.

Amoco Organization and Operations - Mr. Ron Fisher of BP Amoco gave an overview of BP Amoco’s crude
quality initiatives. BP Amoco
has 85,000 employees in 100 countries.The company is involved in Exploration and Production, Refining,
Chemicals, Shipping and Marketing. The
eight U.S. refineries run combinations of sweet and sour crudes.
Crude quality receives attention from two full time
positions in the U.S. BP
Amoco utilizes the Internet with the IDES (Inspector Data Entry System)
where inspectors digitally interface with the appropriate BP Amoco
employees and quality data is extracted and stored automatically.
BP Amoco also monitors pipeline crude quality with routine samples
that are tested with in-house laboratories.
A BP Amoco intranet system was designed to mange that quality data. BP Amoco Organization View
this Document******** The Use of Drag Reducing Agents – Mr. Mike West of Baker Petrolite spoke to the group about drag reducing agents (DRA). Baker Petrolite has 20 years of history on drag reducing agents; enough to ensure that there are no adverse effects from the chemical to downstream processes or products. The chemical makeup of DRA is continuously being optimized and the ppm dosage required for effective treatment has decreased over the years. DRA works only in turbulent flow and multiple injections may be required as the sheared chemical loses effectiveness while passing through mainline pumping stations. Mike distributed excerpts from Baker Petrolite’s quality assurance manual which definitively describes its FLO pipeline booster. Please contact the COQA facilitator if you’d like a copy of the excerpt or contact Mike directly (281-275-7349 or michael.west@bakerpetrolite.com) if you are interested in the entire manual.

and Petroleum - Mr. Erik Holladay of ITS Caleb Brett spoke to the COQA
about the rapidly growing use of the Internet in managing logistics and
quality in the petroleum industry.
ITS Caleb
Brett has been in business for over 110 years and provides inspecting,
sampling and testing services for a variety of products throughout the
world. ITS Caleb Brett has
available online capabilities that can provide their clients reporting,
quality, and transaction information faster, in new ways, and more
economically than traditional communication means.
Inspection reporting services, database management and quality
monitoring are the types of services provided via the web. One issue the petroleum industry is starting to address is the establishment of common ECommerce standards to enable companies to easily “talk” to one another using their existing, in-house systems. API, the Chemical Industry Data Exchange and others are involved in this process. ITS Caleb Brett is lending its expertise in setting standards for the inspection and testing functions. Please contact Erik directly (eholladay@itscb.com or (713) 407-3533) for additional information. Overview of Crude Oil Quality Round Robin No. 11 - Mr. Gerald Lekberg of Williams presented the results of Round Robin No. 11, Cusiana crude. Forty-five samples were distributed, 25 labs returned results in time for tabulation. With the successful onset of the ASTM cross check, The COQA Round Robin will be discontinued. Thank you to all who participated in the COQA Round Robin and many thanks from the COQA to Gerald Lekberg for initiating and managing the program. Additive Subcommittee - Interested parties met in the morning to discuss a game plan for this new subcommittee. After much discussion, it was decided that the first step should be to distribute a questionnaire to refiners through the U.S. with specific questions on additive components and their effect on operations. The tabulation of the questionnaire responses will be used as a starting point for discussions with producers and manufacturers. All persons interested in additives (both transportation and production) are invited to join the subcommittee. Capline Common Stream Parameters Update - Ms. Patti Edens of Equilon Pipeline reported that the LLS specification program is going extremely well with no additional excursions to report. Mid-Continent Testing/Analyses Update – Patti also reported no excursions on the Basin Pipeline system for Sweet and Super Sweet parameters. Mr. Aaron Dillard of Conoco reported that a summary of all data gathered during the testing and sampling program was distributed to all interested parties. He noted that the minimum /maximum variation has narrowed with the monitoring program. Some next steps for the committee to address are the NYMEX specifications at Midland and a communication to all Mid-Continent shippers asking for their support in expanding quality definitions to include parameters such as distillation points and metals as well as the traditional API and sulfur. Mr. Don Hamilton of Gary-Williams has drafted a memo and he and Aaron plan on distributing it by end February. Anyone wishing to peruse this memo prior to distribution should please contact the facilitator for a draft copy. Update
on CCQTA Projects – Mr. Tim Blackmore of Enbridge Pipelines updated
us on the Canadian projects. The
phosphorus committee has success to report with the introduction of
phosphorus removal technology and also phosphorus free additives.
Both processes are in the developmental stage.
Laboratory testing to aid in the additive screening project
continues. The BS&W
project is also in the sampling and testing stage.
The last samples for the light, sweet Canadian crudes were taken in
September and Crude Quality Inc. is summarizing the results.
A similar sampling and testing project for heavy crudes is in the
sign up stage. COQA Web Site and Budget Report – The COQA web page is now under coqa-inc.org. Comments on the financials or the web page are welcome, please contact the COQA facilitator. Report on Water Measurement Discussion Group - The final version of the discussion paper was distributed to all COQA members in November. Other
Business – The Steering Committee decided to initiate a task force
on moving the industry forward towards adopting the “best available”
technology for water measurement. The
task force will meet the morning of the next COQA meeting date. Next Meeting - The next meeting will be held in Houston on May 31. Harry Giles, COQA Facilitator | |
