CCQTA Guideline for Obtaining Single-Phase Crude Oil Samples for Analysis

publication added: 2018-02-09

This guideline was developed to provide the industry with an educational resource to allow consistent sampling for single-phase fluids.

It is intended to help make sampling more consistent between laboratories and field operators which in turn will provide more consistent samples for subsequent analysis of those samples.

TAN Project Summary

publication added: 2017-11-20

This white paper provides a brief summary of the 14 year history of this project and findings.

The paper provides details what TAN is and how it impacts the crude oil industry. This includes testing methodologies and how TAN is often misinterpreted.

The paper goes further to highlight the specific research work undertaken by the project group and some general conclusions.

Vapor Pressure Measurement Best Practice

publication added: 2017-06-02

The long awaited Vapor Pressure Measurement Best Practice is now available.

This best practice is compilation of the research, understanding and learning gained through the 5 year CCQTA TVP/RVP project and marks the close of the project.

The Best Practice is available to the public promote education around vapor pressure in crude oil.

Response to Transport Canada Regarding H2S Proposed Threshold

publication added: 2017-04-12

Technical review and response to the Transport Canada regarding the proposed H2S thresholds for both rail and road transport.

Bitumen Dewatering and Volumetric Correction

publication added: 2016-04-19

This project was created to set guidelines for the best practices when preparing bitumen samples for analytical work, as well as assess the applicability of API 12.3 “Calculation of Volumetric Shrinkage Resulting from Blending Light Hydrocarbons and Crude Oil” to blends of bitumen and practical diluents.

The report provides correction factors to API 12.3 for use with bitumen blending with diluents.

Temperature Correction of D7975 Field Vapor Pressure Measurement

publication added: 2016-04-18

Safe transport and handling of crude oil and condensate streams requires diligent monitoring of the vapor pressure of these products. Where it is not practical to have an ASTM D6377 instrument onsite such as at an oil gathering battery, trans-loading or rail-loading terminal, a field version of the method was developed as ASTM D7975. The D7975 test method utilizes the same principle of operation as the D6377 test method by expanding a sample of test fluid to a specified vapor/liquid ratio and measuring the resulting pressure. The drawback of the D7975 test method is that is does not allow for accurate temperature control of the test cell and thus results are difficult to compare to laboratory results performed using D6377 as well to operational or product specifications.

The paper provides nomographs and equations to allow easy correction of D7975 data to D6377 for field results comparison to operational or product specifications.

Organic Chlorides - Contaminant Response Protocol

publication added: 2016-02-18

The Contaminant Response Protocol (CRP) is intended to provide an investigative framework that can be used by refiners, shippers and producers to identify the potential source(s) of organic chloride contamination once it has been detected.

Recommendation for Organic Chloride Testing Coupled with Volatile Phosphorus Testing

publication added: 2016-01-08

Document describing the benefits of coupling organic chloride testing with volatile phosphorus testing to validate positive results.

Letter to Industry Regarding Vapor Pressure and Light Ends Measurement

publication added: 2015-07-28

In response to the many requests from the CCQTA for information/input on sampling and testing issues dealing with crude transport by rail & pipeline, some members of the Executive have prepared an information/position paper for distribution to any interested party.

Organic Chloride - Letter to Laboratories

publication added: 2015-07-28

Letter to laboratories regarding the appropriate method reporting of results for organic chlorides. Includes commentary on differences between detection limit terminologies.

TAN Thermometic Testing Report

publication added: 2015-07-28

TAN Thermometric method assessment and comparison to ASTM D664. Report includes the results of the comparison study plus the appendices include the data from two previous ASTM D664 method studies on repeatability and reproducibility on crude oils.

H2S in Crude Measurement Report

publication added: 2015-07-28

This document reports on the results of a project focused on a comparison of existing H2S measurement methods (ASTM D5705, UOP 163, and ASTM D5623) to an adaptation of test method IP 570. The latter method, although not currently validated for crude oil, was prototyped by Stanhope-Seta (UK) and was modified for the complexities of crude oil matrices.

Organic Chloride Test Methods

publication added: 2015-07-28

Letter describing the currently acceptable test methods for performing Organic Chloride testing in crude oils and identifying items for continued investigation.

CCQTA - ASTM D664 TAN Method Modifications For Bitumen Samples

publication added: 2015-07-28

One of the deliverables of the CCQTA TAN project was the identification of the necessary modifications to the existing TAN method that would allow it to be applied to bitumens and heavy oils in a precise and reproducible fashion. The results of this work have been made available for public download and it is our hope that these modifications will be applied by commerical and private laboratories performing this work.

CCQTA - Olefins in Crude Oil by Proton NMR Method

publication added: 2015-07-28

With funding by CAPP and the hard work of Maxxam Analytics, the original release version of the olefins in crude oil by proton NMR is now available for public usage.

Additive Screening Method

publication added: 2015-07-28

This project was put in place to develop the methodology necessary to detect, identify and quantify trace levels of additives commonly used in the production, transportation and refining industries. A methodology has been developed that is capable of doing this for most common additive classes. The project scope was expanded to include publication of the analytical method so that it's existence becomes known throughout the industry.
