Fundamentals of oil sands upgrading
29 Nov 2010 Although Canada's oil sands are more energy intensive to produce and Venezuelan crude, supporting the economic fundamentals of the the incentive to upgrade larger volumes of Canadian oil sand output remains low. 19 May 2015 Heavy oil, extra heavy oil, oil/tar sands bitumen, tight shale oil and in studying the fundamentals of unconventional oil–solid separation in the aqueous J. H. Masliyah and M. R. Gray , Extraction and upgrading of oil sands 13 Dec 2012 What environmental risks might tar sands oil pose if spilled during transportation? Tar Sands: The Basics separate the bitumen, which is upgraded to synthetic crude oil and refined to make asphalt, gasoline, and jet fuel. Upgrading is a process by which bitumen is transformed into light oil by fractionation and chemical treatment, removing virtually all traces of sulphur and heavy metals. Upgraders have 5 basic unit operations: (1) diluent recovery, (2) H:C ratio upgrading through hydrogen addition
There are four ways that are currently practiced in bringing heavy crude oil, such as the Rubiales crude, to market. The first method is to upgrade the material in the oil field and leave much of the material behind as coke, and then pipeline the upgraded material out as synthetic crude. In this
Oil sands upgrading technology could be a game changer By Richard Cairney on May 24, 2018 Industrial research chair Arno De Klerk (right centre) with students, Nexen-CNOOC, Alberta Innovates partners, tour his lab.

Schramm and Fred Wassmuth mechanisms of aqueous foam stability and antifoaming action with and without oil - a thin-film approach, D Though the focus is on bitumen from Alberta's oilsands-the largest resource in the world-the science applies to upgrading of heavy oil and petroleum residue feeds worldwide. Upgrading Oilsands Bitumen and Heavy Oil lays out the current best practice for engineers and scientists in the oilsands and refining industries, government personnel,
18 Jan 2011 This report outlines the nature of oil sands extraction and upgrading ters, not due to fundamental uncertainty about the technologies. Figure 2
Oil Sands Upgrading Chair Upgrading Steps Large molecules that will not distill (called “Residue”) must be cracked to give lighter molecules Cracking takes place in the primary upgrading step at over 400 °C Cracking products rich in sulfur and nitrogen, so secondary upgrading is required to get sulfur below 0.5%
Upgrading Oil Sands and Heavy Oil Upgrading oil sands and heavy oil is an essential part of oil sands development as it adds tremendous value to the raw resource. It allows it to be further processed into fuels and lubricants at existing refineries, and used as feedstock in petrochemical plants — most of which are not engineered to handle these heavy feedstock.
Though the focus is on bitumen from Alberta's oilsands-the largest resource in the world-the science applies to upgrading of heavy oil and petroleum residue feeds worldwide. Upgrading Oilsands Bitumen and Heavy Oil lays out the current best practice for engineers and scientists in the oilsands and refining industries, government personnel, Oil Sands Recovery, Extraction and Upgrading Recovery. Two methods are used to recover oil sands deposits: surface mining, and in-situ. Surface mining collects deposits less than 75 m deep, and accounts for 20 percent of the recovery; about two tonnes of mined oil sands are needed to produce one barrel of Synthetic Crude Oil (SCO). There are four ways that are currently practiced in bringing heavy crude oil, such as the Rubiales crude, to market. The first method is to upgrade the material in the oil field and leave much of the material behind as coke, and then pipeline the upgraded material out as synthetic crude. In this
Why does Alberta have oil sands? 7. Oil Sands. 8. The Basics of Bitumen. 10 In the upgrading process, bitumen is chemically and physically changed into
10 Dec 2012 More and more petroleum is flowing from Alberta's vast oil sands deposits pressure in a process known as "upgrading" to become yellowish crude oil, diesel, The fundamental problem, however, is the growth of fossil-fuel Canada's oil sands resources are located in three major deposits: 1) the Refineries in Alberta processed 311,000 b/d of upgraded bitumen and 23,000 b/d of Surging oil sands production is projected to more than New Builds vs. Upgrades. Oil refining is a capital-intensive business. Planning, design- ing, permitting 11 Oct 2005 oil sands extraction facility using Steam-Assisted Gravity Drainage. (SAGD) hydrogen for upgrading the bitumen from the oil sands to syncrude, a material similar there are any fundamental barriers to licensing the design
Fundamentals of. Materials Oil shale and tar sands occur in dozens of countries around the world. but when Unocal fully upgraded its oil in the early 1990s,. How to recover the bitumen from the oil sands economically and. e f ficiently has current state of knowledge in understanding the fundamentals of bitumen think of mining, extraction and upgrading as three independ- ent operations.
