Condensate Quality Sub-Committee

This committee was formed at the close of the Condensate Quality Project to provide a forum for members to participate, get updates and provide feedback to and from the numerous projects that relate to condensate quality. These projects currently include but are limited to:
-TIOM
-TVP/RVP
-H2S PVT
-Phosphorus
-Organic Chlorides

The intent of the sub-committee is to provide a common linkage between active and closed projects to ensure continuity of the learnings gained from those projects.

This will allow the CCQTA provide feedback, support and education to industry on issues affecting condensate quality.

This sub-committee is currently seeking a CCQTA member to act as Chairperson. The committee currently contains the remaining members of the Condensate Quality Project group.

Crude Oil Compatibility

This project was initiated at the close of the Heavy Oil Compatibility (HOC) project. Poll was taken of the existing project members to determine which of the available methods was most commonly used. The most common response was “other” therefore no consistent method was being used among the project participants. This made comparison of data virtually impossible and the development of a guide or recommendation on compatibility was not possible.

Based on the work that was completed in the HOC, the project group found the various compatibility methods used in industry produced representative results however the results of each method were not comparable to each other. There was a desire to identify a method that was simple, cost sensitive, non-proprietary, and easily deployed across the industry.

Emulsion Characterization

This project is examining the ability of analytical tools to characterize difficult emulsions. An analytical protocol is to be derived that will allow the user to establish the nature of a given emulsion and its likely source/mechanism. The intent of the project is to develop a series of analytical tests to perform on any given desalter emulsion that will allow an understanding of the nature of the emulsion and its root causes. Knowledge of the root causes of an emulsion will assist a refinery, and potentially a crude oil producer, in developing an effective strategy for breaking the emulsion.

H2S PVT Project

This project was initiated to develop a set of graphs that can be used to estimate the vapor phase concentration of H2S based on the liquid phase concentration, the temperature and vapor space ratio above the liquid, using equation of state modeling.

Through the project work is became evident that a simple model based solution was not possible and the project changed its focus to evaluation of H2S evolution risk in crude oils. This project took learnings from the earlier H2S Measurement project as well as the TVP/RVP project to develop an analytical method coupled with established single phase sampling practices.

The result is the development of a H2S evolution and measurement method intended for pressurized samples (ASTM D3700 and/or D8009). This method is fit for purpose for materials that are outside of the scope of the often used ASTM D5705 test method.

Heavy Oil Compatibility/Stability

This project is exploring the best methdology for measuring/predicting stability issues for blends of heavy crude oil with other crude oils.

Open Forum

The open forum meeting format was introduced in the December 2016 schedule to facilitate discussions that did not fall within the scope of the current projects.

There is no fixed agenda to these meetings and members are free to discuss any topics within the confines of the CCQTA mandate.

The expectation is that emerging concerns and issues will be discussed at these meetings and may spur new areas of research relevant to CCQTA all members or to a specific group of members.

Organic Chlorides in Crude Oil

This project is intended to resolve issues with lack of detection, repeatability and reproducibility of organic chlorides measurement in crude oil samples. It is intended to screen testing methodologies, resolve discrepancies, identify optimal/referee method. It will also idenfity the nature/type of organic chloride presenting a problem at this time, and provide sufficient information to allow crude oil shippers to identify/track contamination sources.

Phosphorus in Crude Oil

This project was initiated in 1995, in response to fraction tower fouling observed at three Canadian refineries. Phosphorus was determined to be a significant component of the foulant and traced back to additive usage within the production industry. Since its inception, the project has dealt with various phases of contaminant and key additive identification, elucidation of the fouling mechanism, the development of both chemical and process alternatives, and the implementation of crude oil specifications.

A limit was established, effective July 1, 2005, of a maximum of 0.5 ppm voltile phosphorus in crude by the Canadian Association of Petroleum Producers. Enforcement of this limit has begun effective January 1, 2007.

Pipeline Corrosion

This project which involves major pipelines, is in place to study the concentrations of carbon dioxide, oxygen and hydrogen sulfide in a selection of crude oil streams in the WCSB to provide background knowledge of their levels and their potential significance in corrosion.

Properties of Thermally Processed Materials

Project to investigate the properties of materials that have been thermally processed as a part of a partial upgrading process.

Project goals are:
a. To investigate the differences between cracked and virgin products.

b. Further identify which of those differing properties result in negative impacts to
downstream operations.

c. Develop recommendations to assist in updating specifications if required.

TAN Phase IV

This project will study the impact of higher shear rates, the impact of crude oil blending on corrosivity, and study on the interaction of various types of nap acids and sulphur compunds and their impact on corrosivity. A newly designed autoclave, requiring smaller volumes of sample, will allow reduced residence times and minimal opportunity for carboxylic acid degradation. Additional work will be done on the scales produced on the test coupons surfaces, and the utility of various speciation techniques for napthenic acids and the metal scales is being explored.

Toluene Insoluble Organic Materials (TIOM) Project

This CCQTA sponsored project is investigating the composition and potential sources of TIOM material that has been found throughout the industry.

TIOMs are commonly characterized as asphaltenes since they appears as a black deposit or sludge in tanks, exchangers, reboilers and numerous other systems. What is unique about this material is that it is not soluble in toluene or almost any conventional solvent so it is very problematic and difficult to remove without resorting to mechanical removal methods.

The goal of the project is to locate and understand the source of this material in an attempt to mitigate or eliminate the associated problems.

Transmission Pipeline Sour Service

This project was initiated In response to the National Energy Board requirement for transmission pipelines to meet the CSA Z662 standard for Sour Service.

Project focus is the evaluate the conditions required that would allow sulphide stress cracking to occur which will allow transmission pipeline operations to evaluate their systems and whether the conditions exist to promote SSC.

his project was initiated In response to the National Energy Board requirement for transmission pipelines to meet the CSA Z662 standard for Sour Service.

Project focus is the evaluate the conditions required that would allow sulphide stress cracking to occur which will allow transmission pipeline operations to evaluate their systems and whether the conditions exist to promote SSC.

In March of 2017 the project requested CCQTA funding support so all further information is open to all CCQTA members.

TVP-RVP Relationship

This project is examining the relationship between true vapor pressure and Reid vapor pressure. The exising API nomograph was developed using weathered crude oils, whereas today all crude oils are stabilized and none are weathered. This shift in technology has rendered the API nomograph inaccurate, and a new relationship is desired to accurately reflect todays crude oil production and technology.
