Oxidized Bitumen Process

Applications

Oxidized Bitumen has a wide variety of industrial applications Roof Felts i.e., Water Proofing for Roof & Floors, Anti Rust Pipe Coating, Anti Slip Layer Compound for Piling, Sound Dampening Felts, Under Carriage Sealant and Coats in the Automotives, Electrical Cable Joint Protection (Fillers), Joint Filling Compounds, Sealants, Bituminous Marine Mastic for the Oil & Gas Industry and many more in our day to day life.


Technical Advantages


Durability
Flexibility
Water Resistant
Chemical Stability



Manufacturing Method

Oxidized Bitumen is produced by either Continuous or Staggered Blowing Process. Heated Penetration Grade Bitumen up to 300 deg C under controlled environment is blown with air in the Chimney / Tower. This process removes the Oil Content in the Bitumen and it is oxidized. Fuel oil is added to the process to make the penetration higher, if it is required to do so.

The oxidized bitumen, still at higher temperature, to be handled carefully and packed into Bags or drums as required. The associated safety and work place hazards need to be handled efficiently.
The different grades for suited applications produced are designated by two numbers to indicate the mid-points of their softening point and penetration ranges.

Manufacturing Process

Chemicals are added in order to decrease the time for the reaction time for blowing which shall have better control over the blowing conditions to produce different grades of Oxidized Bitumen with low capital investment.


Blowing is preferably done from the bottom of the Chimney/ Tower and the Temperature can be controlled by Water Jacketing.


Additives


While using distilled Used Oil or Crude Oil for the production of 90/10, 85/25 grades to the tune of 25 percent, care shall be taken the injection of oil shall be free from water to eliminate any explosive reactions during the process.


Dry and Harder Grades


Other grades are produced without adding Oil and the finished product will have near to Zero Penetration is predominantly used in Asia.


Process Control


Capacity of the Tower to be limited to not more than 75 percent as the volume increases with rise in temperature during the process. Injection will take place around 230 degrees.

Tower Temperature shall not exceed 290 degrees as the reaction will get critical leading to explosion.

Oxidation is done when the Admixture enters from the top of the tower and the bitumen at the bottom sprayed through the nozzle at an optimal temperature of 270 degree Celsius. Sampling from the tower has to be analyzed to determine the end point of blowing and the required properties of the final product.


Waste and Recovery


Gas and steam produced in the process shall be circulated through the condenser and separated. Minor amounts of furnace oil shall be recovered which can be reused to hear the furnaces.

Packing

Packing is done when the final product temperature brought down to 160 degrees in bags with Moulds or in steel drum before it cools down to room temperature and become solid.

Oilsands- Koreans Teams up

By Dan Healing, Calgary Herald July 21, 2010 2:04 AM


A $7-billion-a-year Korean construction firm has been contracted by Korea's state oil company to build an oilsands project in northern Alberta, a first for both companies.

GS Engineering & Construction Corp., which builds oil, gas and petrochemical plants, as well as buildings, roads, bridges and harbours around the world, has been awarded the $300-million contract to build the 10,000-barrel-a-day BlackGold Phase 1 project by Korea National Oil Corp.

Regulatory approval for the steam-assisted gravity drainage facility, estimated to cost a total of $400 million to $450 million, was received last year and the company recently filed the paperwork for a 20,000 bpd expansion.

The deal is part of continuing trend by Asian companies to invest in the oilsands to ensure their future energy needs, although there is no current direct bitumen conduit from Alberta to Asia.

KNOC has said it aims to double its worldwide production to 300,000 barrels of oil equivalent by 2012 -- Korea is the seventh largest oil consumer in the world at 2.3 million barrels a day and the fifth largest oil importer.

The BlackGold facility is expected to produce first bitumen by late 2012 or early 2013, and will be operated by Calgary-based Harvest Energy Trust, which KNOC bought for $1.7 billion in December.

"We've been looking at it and now we feel comfortable proceeding with that project," said John Zahary, Harvest president and CEO, adding the technology will be classic SAGD, where steam is injected into the formation with a horizontal well to melt the heavy, sticky oil, which is collected in a second horizontal well.

It's expected to have an average steam-oil ratio of around 3-1, similar to other in situ thermal projects in the area south of Fort McMurray.

The company has not decided whether to use pipeline or truck to get the product to market. "There are number of different options," said Zahary. There is no plan to upgrade the bitumen in-house.

Services sector analyst Jeff Fetterly of CIBC World Markets said the introduction of foreign players in oilsands construction creates an "interesting dynamic" as the pace of resource development heats up in northern Alberta.

"The sense I get and the feedback I get talking to most of the service companies leveraged to the maintenance side or the construction side of the business is there will probably be more than enough work to go around for everyone," he said. "There is a lot of specialist knowledge in terms of understanding where you're developing this project and the region you're working in where the domestic companies are at an advantage, but it's also a function of what the capacity is going to look like."

He pointed out that a foreign general contractor will likely dole out hands-on work to local companies.

But Gil McGowan, president of the Alberta Federation of Labour, said there's no guarantee the project will create jobs for Albertans, adding that unions in Korea have criticized GS's safety record.

"This may end up being the worst of all worlds for Albertans," he said. "We face the prospect of losing jobs in both construction and upgrading if this project is allowed to proceed."

On its website, GS lists one North American office, in Houston, and 10 in Asia and the Middle East, including two in China. It says it had record revenue and earnings in its last fiscal year, generating 569 billion won ($492 million) in operating profits on revenues of 7.8 trillion won ($7 billion).

KNOC acquired the Black-Gold leases in August 2006.

Other Asian stakes in the oilsands are held by Chinese and Japanese interests.

China Investment Corp. has a 45 per cent stake in Penn West's Peace River oilsands assets, Petro China has invested $1.9 billion in Athabasca Oil Sands Corp., Sinopec has a 50 per cent interest in the Northern Lights oilsands project and recently bought a nine per cent stake in Syncrude Canada, while China National Off - shore Oil Corp. has a 16.7 per cent interest in privately held oilsands developer MEG Energy.

Japan Canada Oil Sands Ltd., owned by a Tokyo Stock Exchange-listed company, applied in April to expand its 8,000-barrels-a-day pilot SAGD oilsands project at Hangingstone by 35,000 bpd.
