Alberta, Canada has the world’s third largest oil reserves within the type of oil sands. Extracting and processing the oil from the sands and bedrock is a difficult process and requires the largest slurry pump within the oil sands trade.
When it involves pumping slurry, there can be only a few functions which would possibly be tougher than the hydro-transport of heavy-duty slurries in oil sands production. Not only do the pumps should deal with the highly aggressive nature of the fluid being pumped, they are also expected to function in a few of the harshest environments on the earth.
In January 2020, GIW Industries, Inc., a KSB firm, commissioned its largest ever heavy-duty centrifugal slurry pump for operation in Canada’s oil sands, particularly the Tie Bolt Construction (TBC-92). Named after its ninety two in (2337 mm) impeller, the TBC-92 is the most important and heaviest slurry pump obtainable in the oil sands industry and the most recent in a line of highly effective high-pressure pumps provided by GIW.
Slurry transportation Slurry transport covers a substantial range of industry sectors, ranging from food and beverage to mining. What is common to all, is that the pumps used should be capable of transport liquids containing particles and solids of various sizes and viscosities. In mining, dredging and oil sands production, the most important problem is to accommodate excessive density slurry and highly abrasive grits.
It is important that the slurry passes through the pump with the minimal quantity of damage to the pump casing, impeller, shaft and sealing mechanism. Furthermore, the pump have to be able to delivering excessive flows and in a place to withstand harsh operating environments.
Alberta in Canada has in depth oil reserves and these are within the form of oil sands. Extracting and processing the oil from the sands and bedrock is challenging, involving the removal of bituminous ore which is transported to a crushing plant. The crushed ore is then combined with heat water to kind a dense slurry that can be transported within the pipeline in course of extraction, the place the bitumen is separated from the sand and rock. After extraction, the remaining solids (or tailings) are often transported by way of different pumps to settling ponds.
The processes require in depth use of slurry and water transportation pumps able to handling vast portions of liquids at excessive pressures and excessive temp- eratures. Drawing on its lengthy experience of designing slurry pumps for mining, GIW has custom-engineered slurry pumps that mix advanced supplies, hydraulics and patented mechanical designs, the newest of which is the TBC-92.
Meeting challenges Mollie Timmerman, GIW business growth manager, explains extra: “Our consumer wanted the next capacity pump which was able to 10,000–11,000 m3 per hour of output at nearly forty m of developed head and a maximum working strain of 4000 kPa. The pump additionally wanted to have the ability to pass rocks of approximately 130 mm in diameter with a total passage dimension requirement of 10 in (or 254 mm) and deal with slurry densities in excess of 1.5 SG.
In addition, the shopper was focusing on a maintenance interval (operational time between deliberate maintenance) of round 3,000 hours. They had expressed an interest in maximising the upkeep intervals and primarily based on initial wear indications, they are presently hoping to realize around 6,000 hours between pump overhauls (i.e. 6–8 months).”
The instant application for the primary batch of GIW’s TBC-92 pumps in Alberta is in hydro-transport service the place they’re used to move bitu- minous ore from the crusher to the extraction plant. The liquid pumped is a mixture of water, bitumen, sand, and enormous rocks. Screens are in place to keep these rocks to a manageable dimension for the process, however the high size can nonetheless usually reach up to one hundred thirty mm in diameter or bigger.
The abrasive nature of the slurry is what separates a slurry pump from different pumps used in the industry. Wear and erosion are facts of life, and GIW has a long time of expertise within the design of slurry pumps and the development of materials to help lengthen the service life of those critical elements to match the deliberate maintenance cycles within the plant.
“GIW already had a pump capable of the output requirement, this being the MDX-750, which has been a preferred measurement in mill duties for nearly 10 years through- out Central and South America,” explains Mollie Timmerman. ”However, the customer’s software required a pump with larger strain capabilities and the aptitude of dealing with larger rocks so we responded with the event of the TBC-92 which supplied the most effective answer for maximised production.”
The TBC sequence The development fashion of GIW’s TBC pump range options massive, ribbed plates held along with tie bolts for very high-pressure service and most wear efficiency. First developed for dredge service, then later launched into the oil sands in the 1990s, the TBC pump series has grown into a totally developed range of pumps serving the oil sands, phosphate, dredging and hard rock mining industries for tailings and hydrotransport functions.
The pumps are sometimes grouped together in booster stations to construct pressure as high as 750 psi (5171 kPa) to account for the pipe losses encountered over such lengthy distances. The strong building of the TBC pump is properly suited to do the job, whereas ensuring maximum availability of the tools beneath closely abrasive wear.
Capable of delivering stress as much as 37 bar and flows of greater than 18,200m³/h and temperatures as much as 120o C, the TBC range is a horizontal, finish suction centrifugal pump that gives maximum resistance to put on. Simple to maintain, the pump’s tie-bolt design transfers stress hundreds away from the damage resistant white iron casing to the non- bearing side plates without using heavy and unwieldy double-wall development.
The TBC-92 combines the most effective elements of earlier TBC models, together with the TBC-84 oil sands tailing pump, also referred to as the Super Pump. The pump additionally incorporates options from GIW’s MDX product line, which is used in heavy-duty mining circuits throughout the world of hard rock mining.
In total, the TBC-92 weighs about 209,000 lbs (95,000 kg), which is roughly equivalent to a fully-loaded Airbus A321 aeroplane. The casing alone weighs 34,000 lbs (15,500 kg). Key options of the pump embody a slurry diverter that dramatically will increase suction liner life by lowering particle recirculation between the impeller and the liner. The large diameter impeller allows the pump to run at slower speeds so that wear life is enhanced. The lower velocity additionally offers the pump the power to operate over a wider vary of flows so as to accommodate fluctuating move circumstances.
To make maintenance easier, the pump is fitted with a special two-piece suction plate design which helps to cut back device time and supply safer lifting. Customers obtain pump-specific lifting devices to facilitate the secure removing and set up of wear comp- onents. The pump additionally features a longlasting suction liner that can be adjusted without having to shut the pump down.
New milestone The commissioning of the TBC-92 marks an necessary milestone for GIW, which now has pumps in service in any respect operating Canadian oil sands plants for hydrotransport purposes. The TBC-92 has been designed to deal with heavy-duty slurry transport whereas offering a low total price of ownership. Minimal labour and maintenance time help to maximise manufacturing and profit.
“This new pump incorporates the teachings learned from operating within the oil sands over many years, and features our latest hydraulic and wear technologies,” says Mollie Timmerman. “Because this is the heaviest TBC pump we have ever designed, specific consideration was given to maintainability, as well as materials choice and construction of the pressure-containing parts.”
That GIW has established itself as a major force in pumping options for the oil sands industry is far from shocking provided that it has been developing pumping technologies and put on resistant materials in the world mining industry since the 1940s.
These pumps have had a substantial impact on the finest way that excavated sand, rock and bitumen are transported to the upgrader plant. By adding water to the excavated material it turns into extremely efficient to pump the slurry alongside a pipeline to the upgrader. The pipeline agitation assists in separating the bitumen from the sand as it is transported, plus there’s the additional good thing about eradicating using vans.
GIW has estimated that the price of shifting oil sand in this way can reduce prices by US$2 a barrel, and it is way more environmentally pleasant. These pumps additionally play a significant role in transporting the coarse tailings to the tailings ponds. GIW provides pumps used in the extraction course of and other areas of production (HVF, MDX, LSA).
Understanding เกจวัดแรงอัดกระบอกสูบ Understanding the nature of slurries and how they behave when being pumped has been basic to the development of those products. GIW has been obtaining slurry samples from customers over many years for testing hydraulics and supplies both for pumps and pipelines. Research & Development facilities embody multiple slurry take a look at beds on the campus, together with a hydraulics laboratory that’s dedicated to pump efficiency testing.
These actions are central to the company’s pump development programmes. If companies are experiencing issues the GIW R&D personnel can see where the issue lies and supply recommendation for remedial action. Experience does point out that in lots of cases the problem lies not with the pump nonetheless, but in the interplay between the pipeline and the pump.
Feedback from prospects about appli- cations helps within the growth of latest instruments and pump designs. By bringing to- gether prospects and academics from all round the world to share their experience and analysis with in-house experts, the massive funding in analysis, improvement and manufacturing has superior the design of all of the GIW pump merchandise,supplies and wear-resistant elements.
The future “There is a transparent pattern towards bigger pumps in mining and dredging and oil sands are no exception,” feedback Leo Perry, GIW lead product manager. “The first TBC pump in the oil sands trade was the TBC-46 (46 in being the diameter of the impeller). Customers are designing their facilities for higher and better production and demanding the same of the equipment that keeps their production transferring. While these larger pumps demand more energy, in addition they enable for higher production with much less downtime required for upkeep. Overall, the effectivity improves when in comparability with the identical output from a bigger quantity of smaller pumps. “
In conclusion, he says: “Larger pumps go hand-in-hand with larger services, larger pipelines, and increased production, all of which proceed to pattern greater year after yr. Other prospects and industries have additionally proven an interest on this measurement, and it will be no shock in any respect to see extra of these pumps built in the near future for similar functions.”
