Summary Crude Oil Quality Association Additives
Subcommittee Houston, TX May
31, 2001 The meeting agenda
was distributed to those in attendance. Results
to Date of Additive Survey
- The survey on additive components was distributed in March and
twelve replies were received. A
summary of the replies will be available to all COQA members after the
respondents have reviewed it. Harry Giles, COQA facilitator, shared a few observations on the survey.
Once the
summary is finalized, it will be used to start a dialogue with additive
manufacturers not yet represented in the COQA and with crude oil
producers. Methanol
Alternatives for Hydrate Inhibition - Dr. Lynn Frostman of Baker
Petrolite shared information about her company’s new hydrate inhibitor
which is intended to be utilized as a methanol substitute. These chemicals allow hydrates to form but keep them in small,
well-dispersed, flowing form. Dosages
are very low (Low Dosage Hydrate Inhibitors – LDHI) which has several
advantages; cost, storage and transportation, and easier injection.
LDHI’s have been successfully used in deepwater Gulf of Mexico,
in the North Sea and onshore in Canada. There are some downstream concerns with LDHI’s; such as the impact on the Desalter, the Biotreater and overhead corrosion. Baker Petrolite has done some testing and, so far, the adverse effects have been minimal or, in the case of corrosion, treatable. The dilution effects of multiple crude streams being commingled prior to reaching the refinery, coupled with the low application rates, tend to minimize the amount of LDHI entering the refinery. Another concern is the possible impact on end products. This issue is under investigation with bench scale experimentation and perhaps a pilot refinery test. Jet fuel, the government's specific jet requirements such as JP8, and diesel are the products being investigated. Baker Petrolite welcomes input from the industry. Please contact Lynn (281-276-5415 or Lynn.Frostman@bakerpetrolite.com) if you have ideas on testing or other studies. Baker Petrolite LDHI - View

Additive Report – The
CCQTA has had an additive study group for some time.
The goal of the group was to establish a standard, analytical test
method to track and detect chemical additives with the further objective
of incorporating that method into new additive testing and development.
A protocol for the test has been designed and work on developing
the full, standardized method began last year.
Products in the future will most likely have even tighter
specifications than now and there will continue to be considerable
incentive to improve the quality of the crude oil feedstock.
The protocol developed uses techniques that are readily available
at additive supplier development labs and the Additive Screening Project
Group expects widespread usage of the method when it is finalized. If
you are interested in a copy of the summary report, please contact the
