Playing an integral role in the water recovery process during SAGD Oil Sands projects, Hot Lime Softeners reduce the amounts of oxygen, carbon dioxide, silica, hardness, trace oil, and other suspended solids in water destined for use as boiler feed water.
These teardrop-shaped pressure vessels feature a spherical top and cone bottom, built in accordance with our ASME Certificate of Authorization for Section VIII Division 1 & 2.
TIW will design, fabricate and field erect these vessels as well as conduct repairs.
We’ve fabricated and constructed several cone bottom spheres with various sized diameters. The table below shows some some typical sizes based on diameter, number & size of columns and capacity in barrels
| Diameter | Number of Columns | Size of Columns | Capacity / Barrels |
|---|---|---|---|
| 38′ | 6 | 12″ | 5,000 |
| 48′ | 8 | 16″ | 10,000 |
| 55′ | 9 | 20″ | 15,000 |
| 60′ | 10 | 24″ | 20,000 |
| 65′ | 10 | 26″ | 25,000 |
| 69′ | 11 | 26″ | 30,000 |
| 73′ | 12 | 28″ | 35,000 |
| 76′ | 12 | 30″ | 40,000 |
| 79′ | 13 | 32″ | 45,000 |
| 82′ | 13 | 34″ | 50,000 |
Our design engineers can customize a wide range of appurtenances on the interior and exterior of your cone bottom spheres. At our in-house, 200,000 sq ft material processing plant, we fabricate everything from nozzles, vents and piping to custom stairways and platforms.
Here are some typical components we design, fabricate and install on our ASME Hot Lime Softeners…
There are a wide variety of protective coating options that we can provide for corrosion prevention. TIW can offer a variety of external coatings and interior lining. We also offer alternate corrosion options such as hot dip galvanizing, coating over galvanized components and fireproof coating.
Shop Pre-CoatingTIW can shop coat plates and appurtenances prior to shipping to site. This can help offset the high prices of field coating and help minimize open-air blasting which can be environmentally prohibited in some project locations.
GalvanizingWe provide galvanizing of various components – from nozzles, piping and support clips to stairways and platforms. In some cases, both galvanizing and coating are applied providing a superior protection.
These coatings are applied to the exterior of the vessel for corrosion protection and cosmetic appearance. Some typical coatings we use include:
The interior surface of the vessel can be partially and fully coated with a submersion grade epoxy lining. TIW removes all sharp edges before sandblasting any area, and can perform complete Holiday testing (to test for voids in the liner), prior to signing off on the lining. Typical linings used include:
When temperature control is required per design, TIW can supply and install a variety of mechanical insulation to meet the customer’s requirements. Insulation options can vary from the more common insulation batts with external cladding to prefabricated insulated panels. There are also different insulation and cladding material options.
Depending on design and temperature requirements, TIW can offer several insulation materials such as:
As Canada’s premier builder of tank and vessels, TIW has established itself as a dependable partner for high quality construction of specialty vessels in the oil sands industry.
Since constructing 4 large, 288-ft diameter “hot” (400°F) bitumen tanks in 1975 at a giant oil sands processing plant in Western Canada (reputed to be the largest “hot” tanks in the world at the time), we’ve continually improved our process, relentlessly improving efficiency and cost-effectiveness from the design phase through construction in the field.
Our crew of highly skilled quality control and safety personnel, field supervisors, and certified tradespeople ensure your project is a success from start to finish, while our technical expertise in design, engineering, fabrication, field erection, and repair allows us to provide extraordinary service.
Known throughout the industry for our in-depth knowledge, dedicated work ethic and stringent standards for safety and quality control, we deliver projects that exceed our clients’ highest expectations, on time and on budget.
