Application, Design and Experience

Our facility is ready to manufacture and deliver generators that will keep your well pumping oil Non-Stop. We are ready to deliver Enhanced Oil Recovery steam generator projects of all sizes, from completely packaged skid-mounted units to large field-erected Enhanced Oil Recovery OTSGs... and everything in between. We work hard with our customers to reduce risk and minimize the total installed cost, in execution time and reduced capital investment.

Application – Size Range

Less then 100 MMBtu/hr
These units will be completely manufactured and assembled in IST’s Cambridge, Ontario, Canada, facility and will be shipped to site ready for installation.

Over 100 MMBtu/hr
All pressure part sub-assemblies will be manufactured in IST’s Cambridge, Ontario, Canada, facility.

For Steam Assisted Gravity Drainage (SAGD) projects in Alberta, Aecon Industrial’s Edmonton, Alberta, fabrication shop will complete final assembly of the units and ship directly to site.

Design

Fired Once Through Steam Generator

• Generate saturated steam with quality <80%
• Burner Duty from <50 to >300 MMBtu/hr
• Boiler designed to ASME Section I and American Petroleum Institute (API) specifications
• Piping designed to ASME B31.1
• Operating pressures up to 2500psi

Radiant Module

• Cylinder diameter from <12 ft to >30 ft
• Cylinder length about 3x diameter
• Single-circuit or multi-circuit design
• Multi-circuits can be either parallel-pass or circuit-by-sector design
• Internally insulated with ceramic fibre blanket, modules and refractory. Casing is carbon steel.

Convective Module

• Consists of a serpentine finned tube module
• Tubesheets at the ends are carbon steel with refractory installed on the hot side
• Intermediate tubesheets may be necessary for larger convective sections
• Single circuit or multi-circuit design
• Multi-circuits can be either parallel-pass or circuit-by-sector design

Fuel

• Natural gas, oils, process and bi-product fuels are suitable

Experience

The Struthers Wells technology is used in many of the boilers operating in oil fields today. There are over 1,200 Struther’s steam generators in service throughout the world.

1851
Struthers Wells established in Warren, Pennsylvania, as foundry and manufacturer for agricultural industry

1859
Design and fabricate process equipment for oil industry

1908
Produce the first all-welded carbon steel pressure vessel

1940-1960         
Developed the forced-circulation thermal fluid vaporizer that has now become the clear first choice in organic fluid vaporization technology.

Manufactured the first furnace used for thermal cracking (pyrolysis) of ethylene dichloride (EDC) to produce vinyl chloride monomer (VCM) in 1960, replacing the older and more troublesome catalytic process. This initial success was followed by the supply of over 100 EDC cracking furnaces worldwide.

Developed a convective-only titanium tetrachloride (TiCl4) preheater/boiler/superheater to achieve the lowest practical film temperatures with low overall pressure drop. The tightly controlled film temperatures permitted the use of metal tubes instead of unwieldy quartz tubes.

1962
Designed and built the first oil-field heater generating 80% quality steam at up to 2,500 psig using high TDS feedwater. This pioneering once-through boiler design quickly became the industry standard for secondary thermal enhanced oil recovery. Struthers Wells followed this success with over 1,200 installations and 60 billion Btu/h (17,600 MWt) installed capacity worldwide.

1994
Intellectual property purchased by Struthers Industries, Inc.

2005
Intellectual property purchased by Thermal Engineering International (USA) Inc. to form TEi-Struthers Wells.

2006
EOR OTSG consortium formed with IST

Today, TEi-Struthers Wells is committed to continuously improving on its technology, producing heaters that are more efficient and reliable than ever before.

Footnote:
Thermal Engineering International (TEi), Santa Fe Springs, CA, a  Babcock Power Inc. company,  acquired the Intellectual Property Assets of Struthers Industries and Struthers Wells in May 2005.

IST has been engineering and manufacturing Once Through Steam Generators for the power industry for over 15 years. IST units are designed and manufactured in Canada with 110 units operating in 14 countries.

1970s
The Once Through heat recovery technology is developed as a joint venture between Solar Turbines and the U.S. Navy with their RACER (Rankine Cycle Energy Recovery) Program. The development is based in San Diego, California.

1985
Solar Turbines delivers its first units to a cogeneration plant in Okarche, Oklahoma. The units are coupled to 3 MW Solar Centaur Gas Turbines.

1992
The first OTSGs in Canada are installed at a TransCanada Pipeline enhanced combined cycle plant in Nipigon, Ontario.

1992
The OTSG technology is bought by Nicholls Radtke. Innovative Steam Technologies is formed and the existing company is moved to Cambridge, Ontario.

2001
IST opens a European Sales Office in an effort to be more accessible to our European customers.

2001
ARMBRO BFC becomes AECON Group Inc. www.aecon.com

2006
IST sells 100th OTSG in Maui, Hawaii. New advances in materials and design are made.
