Pacific BioEnergy Gives Humanely

PRINCE GEORGE – The Prince George Humane Society and Pacific Bioenergy have joined forces. Strange bedfellows, you think? Oddly, no.

“When we heard about an opportunity to donate to the Humane Society, to provide products for the cats, we were all in,” says Shawn Bell, Vice President of Operations.

Cleaner Fibre – Pacific BioEnergy reduces machine wear with ClassiCleaner

By Maria Church

Pacific BioEnergy’s 350,000-tonnes per year pellet plant in Prince George, B.C., consumes up to 1,200 tonnes of fibre a day, sourced from sawmill and forest residuals as well as low-quality whole logs. A new multi-million dollar installation from Dieffenbacher allows the industrial pellet plant to reduce machine wear and access more fibre sources than ever before.

The installation, called a ClassiCleaner, uses a combination of roller screening and air separation units to filter out contaminants before fibre enters the hammer mills. It’s the first installation in North America, says Shawn Bells, Pacific BioEnergy’s (PacBio) vice-president of operations.

PacBio’s vice-president of operations, Shawn Bells, says the ClassiCleaner will reduce their maintenance costs by at least 10 per cent.

“It’s exciting technology,” Bells says during Canadian Biomass’ tour of the plant and new installation in April. He points to a bag filled with grain-sized rocks and flecks of wood throughout — the bag was collected from the ClassiCleaner’s smallest particle separation bins. After months in operation, Bells is more than pleased with the results.

“This ClassiCleaner was a strategic investment to allow us to open up access to higher-contaminated fibre streams. It gives us the ability now to run the plant on 100 per cent forest residuals,” he says.

PacBio has a non-replaceable forest licence in the Quesnel forest district, which allows them to harvest 700,000 cubic metres annually. In partnership with Tolko, the company has a biomass pre-processing facility in Quesnel where fibre is chipped with an 84-inch West Salem chipper.

In 2010 the pellet plant began increasing its consumption of forest residuals, local spruce, pine and fir. On average about 30 per cent of plant’s diet is sourced from brush piles, but that has increased to more than 40 per cent, Bells says. The plant also consumes low-quality pulp logs, and sawmill residuals — chips, sawdust and hog streams — from nearby mills. The variety of fibre consumed is a both a blessing and curse, Bells says. More sources amounts to a steadier fibre supply, but the plant’s equipment needs to handle a wide spectrum of particle sizes and contaminants.

PacBio trialled a vibratory air knife separator five years ago in an attempt to handle forest residuals and sawmill hog streams, both of which have high amounts of rock and other debris. The system didn’t meet their requirements, which forced the company to look for another solution.

Bells toured two ClassiCleaner installations in Europe — one in France, and another in Ireland. He was impressed with what he saw. “Europe does an excellent job of recycling everything,” Bells says. But the pellet operation has unique demands.

The ClassiCleaner was commissioned in December after a 24-week project involving PacBio, Dieffenbacher and local firm, International Quest Engineering. One of their challenges was to install the system while the plant continued to operate 24-7.

A different size of contamination is extracted in each section of the installation via a combination of scalping rolls, air knife separation, diamond roll beds and individual gravimetric separators.

The entire system is housed in three separate towers connected by a series of conveyors. A different size of contamination is extracted in each section, via a combination of scalping rolls, air knife separation, diamond roll beds and individual gravimetric separators.

A few weeks into operations, PacBio ran into challenges with the heavy particle separation unit. Dieffenbacher is re-engineering the scalping screens to reduce the amount of wood in the reject material from the heavy particle separation unit. Bells says the support from Deiffenbacher has been exceptional. “They are committed to providing the best possible solution.

“Our setup is probably the most challenging Dieffenbacher has had to do for two reasons: One, the volume this facility processes is in excess of 50 ODT an hour, and two, the spectrum of particle size that it has to clean. We have to treat everything from 100 per cent forest residuals to 100 per cent sawdust. It has to do the full spectrum of everything,” he says.

Bells says the conservative estimate is that the ClassiCleaner will reduce their maintenance costs by 10 per cent. Wear parts that were once changed multiple times a week are now checked once a week and left in place. He says they can hear the difference in the downstream equipment when the ClassiCleaner is not running.

“Now that we know how many contaminants are actually in our feedstock material, we endeavour to run the ClassiCleaner with 100 per cent uptime,” Bells says.

It’s not only the reduction in maintenance costs they can look forward to, it’s also the ability to access other streams of fibre that they normally couldn’t run because of contaminants. That will mean more access to forest residuals and sawmill hog that have the highest amounts of rock and other debris. The plant will be able to reliably handle this material without subjecting its equipment to increased wear.

Plant process

Fibre enters the plant in one of three infeed bins with variable frequency drives, designated for either forest residuals, sawdust or shavings.

The entire ClassiCleaner system is housed in three separate towers connected by a series of conveyors

The forest residuals and sawdust lines are first treated to the ClassiCleaner where contaminants are filtered out and the feedstock material is classified by particle size. The coarse material is fed into either the 800-hp Brunette BioSizer or the 500-hp LAMB Hog, which takes one to four-inch residuals and mulches it to a ½-inch minus. The smaller particulate bypasses the hogs and flows directly to the dryers with the shavings line that skips the ClassiCleaner.

The plant has two SolaGen dryers with 72-million BTU burners fuelled by wood dust, and supplemented by natural gas. Single ducts running from each of the dryers then split into two Allied Blower cyclones, each of which are close-coupled to either 400-hp Bliss hammer mills, or a 500-hp Andritz hammer mills.

From there paddle chain conveyors bring material to one of 10 Andritz pelletizers. Five of the older pelletizers have individual coolers underneath, while the five newer pelletizers installed in 2010 have a shared conveyor to bring the pellets to a large Law-Marot-Milpro (LMM) cooler. Vibrating screens extract the pellet fines, which are brought to dyers’ burners, and finished pellets are conveyed either into one of two storage silos or loaded directly into rail cars.

The entire process from infeed to railcars is between 30 and 45 minutes.

New horizons

PacBio’s history can be traced back to 1994, when partners John Swaan and Carrier Lumber established Pellet Flame. The company became the first in Canada to produce industrial wood pellets for the overseas bulk commercial market in 1998. Today 100 per cent of the plant’s production is shipped to utilities in Europe or Asia.

Last summer Sumitomo Corporation — the owner of several power generation plants in Japan — acquired a 48 per cent equity interest in PacBio. The new part owners mean greater access to the growing Japanese market, Bells says.

“The opportunity in the Japanese marketplace is huge,” Bells says. “We’re geographically advantaged to ship in that direction rather than to Europe. Long term the Asia Pacific marketplace is our focus.”

Investigation Continues into Emergency Incident at Pacific BioEnergy’s Prince George Plant

An investigation into what caused a small fire at Pacific BioEnergy’s Prince George Plant on Friday evening continues. Crews from four halls of the Prince George Fire and Rescue department responded to a call at approximately 8:00 p.m. The crew from Pacific BioEnergy immediately actioned the fire but called Prince George Fire and Rescue for backup when smoke began to enter the adjacent production building making it unsafe to continue to action. The fire originated in the cooler exhaust stack and was isolated to the stack and incoming ductwork. There were no injuries as a result of the incident. The heat from the fire compromised the structural integrity of the exhaust stack which has been removed for replacement. A full investigation into the cause of the fire will be conducted.

Shawn Bells, Vice President, Operations for Pacific Bioenergy states “We want to thank both the Prince George Fire and Rescue department for its quick response to the incident at our plant on Friday evening. I also want to sincerely thank our staff on duty that evening. It is clear that the time and resources we’ve invested in our people in safety and emergency response training is working. It is also clear that the investments in safety monitoring systems that we’ve made during the past several years are also paying dividends. The situation was contained quickly and effectively by the combined response of the Prince George Fire and Rescue department and our own Pacific BioEnergy team.”

Pacific BioEnergy is Canada’s second largest wood pellet producer with an annual production of 510,000 tons. The company owns a large wood pellet manufacturing plant in Prince George and also manages wood pellet plants in Chetwynd and Fort St John in partnership with Canfor. Since Pacific BioEnergy was founded in 1994 it has exported approximately 3.5 million tons of wood pellets to markets in Europe and Asia. Pacific BioEnergy’s Prince George plant has significantly helped improve air quality by taking material formerly burned in beehive burners and using the material to produce renewable wood pellets for use in power plants in Europe and Asia.

Pacific BioEnergy Observes 2018 National Day of Mourning

Pacific BioEnergy and its’ employees observed this year’s National Day of Mourning at a Safety Meeting on April 27th (April 28 is the official National Day of Mourning). The company feels strongly that taking time for a moment of silence to honor the lives lost on the job. Last year, 158 B.C. workers died from a workplace injury or disease.

The annual occurrence is especially important for employees at Pacific BioEnergy as our industry has sustained catastrophic events that resulted in shaping safer work environments for each of us.  Observation of the annual National Day of Mourning also provides extra incentive to stay focused and diligent when it comes to safety both at work and at home.

Pacific BioEnergy Attends Work BC 2018 Job Fair

Human Resources Manager, Sharel Grimm and Safety and Environmental Manager, Darren Marutt were on hand at the Work BC Job Fair held on April 11th at the Work BC Centre in Prince George. Hundreds of people attended the event to research new job opportunities and to speak one-on-one with prospective new employers.

Grimm states “Attending Job Fairs allows Pacific BioEnergy to meet prospective new employees and explain first-hand what we do, what we value and why we are an employer of choice.   Posting a Job opportunity on a website is a good start but being able to interact with people provides an arena for an informal 2-way interview process to take place – we recognize that we are being interviewed as well”.

Marutt adds “Being able to meet people at a Job Fair like this gives us the opportunity to meet potential employees that would be a good fit for our Company.  We’re looking for people who are team-oriented and have a passion for producing superior clean, green wood pellets which help improve the environment and make the world a better place. You can learn a lot about a person from reading their resume but the value in being able to meet them and engage in a conversation at a Job Fair like this is huge for us.”

Pacific BioEnergy Celebrates NAOSH Week

Pacific BioEnergy and its’ employees will celebrate North American Occupational Safety and Health (NAOSH) Week May 6-12. The theme this year is Take Safety Home. This will be the 3rd year that Pacific BioEnergy has celebrated this important event with an Employee BBQ and other activities that are focused on safety at work and at home.

While safety is a core value of Pacific BioEnergy that is front and centre for employees each week of the year, NAOSH Week provides the opportunity to celebrate Safety Success and the benefits of a team-approach to improving safety at work and at home

Pacific BioEnergy Partners with PG Humane Society

Pacific BioEnergy started 2018 with a new partnership with the Prince George Humane Society. The Prince George Humane Society is a community based, registered charity that provides a safe haven for abused, neglected and abandoned animals in the north.

Over the past few years, staff and volunteers at the Society determined that they preferred to use wood pellets instead of chemical-based kitty-litter. Wood pellets absorb a lot more odor and were easier to work with but purchase of wood pellets meant the Society was using valuable funds that were needed to help the animals in care. The Society approached Pacific BioEnergy and requested a partnership that would supply all its wood pellet needs and since January, Pacific BioEnergy has been supplying pellets to the PG Humane Society. Pacific BioEnergy is proud that it’s renewable energy alternative wood pellets have another useful purpose in helping animals in need.
