Top 10 Heyl & Patterson Blog Posts of 2014: The Year in Review

Posted by H&P Blog on Tue, Dec 30, 2014 @ 08:50 AM

The Heyl & Patterson Blog, or simply the H&P Blog as it is known on social media, has been posting articles regularly since 2010.  At Heyl & Patterson, our goal is to educate and inform you about the latest developments in your industries.  This forum has covered topics as varied as the industries we serve, from explaining the inner workings of conduction dryers to examining how a railway across Colombia could compete with the Panama Canal.  As the author of this blog, I've never broken the fourth wall, but I'd like to thank all of our subscribers for following us, and if you haven't yet read the Heyl & Patterson Blog, this is a good time to start.

H&P Process Spotlight: Oil Sands Processing

Posted by H&P Blog on Wed, Sep 10, 2014 @ 10:12 AM

Canada's oil sand deposits contain the world’s second largest oil resource, after Saudi Arabia.  Surface mining can extract around 20% of the oil and currently covers about 342 square miles in the province of Alberta, roughly two-thirds the size of the city of Los Angeles.  In their natural state, oil sands are loose particles that are a combination of clay, sand and water saturated with bitumen.  Processing of this material fundamentally separates oil-bearing bitumen from the sand itself, and can also be referred to as bituminous sands.

H&P Process Spotlight: Activated Carbon

Posted by H&P Blog on Wed, Jun 18, 2014 @ 09:39 AM

Activated carbon is a material that is riddled with tiny pores that increase its surface area, making more of it available for chemical reactions.  It is used for water filtration, gas purification, sewage treatment and metal extraction.  More precisely, it removes color and impurities from liquids and gases, and separates and extracts chemical compounds.  Activated carbon is most commonly found in aquarium filters, respirators and gas masks, and is used to treat poison following oral ingestion.

H&P Process Spotlight: Fertilizer Processing

Posted by H&P Blog on Wed, May 22, 2013 @ 10:47 AM

Fertilizers have significantly improved the quality and quantity of the food available today.  Modern fertilizers are composed mainly of nitrogen, phosphorous and potassium compounds.  These components have limited quantities in soil, and they dwindle as plants are harvested, causing a reduction in the quality and yield of plants.  Fertilizers replace the chemical components that are taken from the soil by growing plants and actually create a better growing environment than natural soil.

H&P Process Spotlight: Dried Distillers Grain Processing

Posted by H&P Blog on Wed, Feb 06, 2013 @ 10:40 AM

The process of fermenting beer has been a staple in civilization since the dawn of time.  Fermentation is the biological process in which sugars such as glucose, fructose, and sucrose are converted into cellular energy, producing ethanol and carbon dioxide.  In the brewing process, grains are boiled, allowing the brewer to gather as much fermentable liquid from the grains as possible.  In most cases, the leftover spent grain, or dried distillers grain, becomes waste that can be cheaply sold as feedstock.

H&P Process Spotlight: Frac Sand Processing for Marcellus Shale

Posted by H&P Blog on Wed, Oct 24, 2012 @ 11:49 AM

To reach gas that was previously thought to be unreachable, pressure is used to fracture or "frac" rock formations deep underground to allow a better flow of gas through a well.  When the pressure is removed, the fracture closes back up, which dramatically diminishes its effectiveness.  Frac sand is pumped into the well with a mix of water and chemicals during the fracturing operation.  The sand will remain in the fracture when the pressure is removed, keeping the fracture propped open and allowing the gas to continue to flow through the well.

H&P Process Spotlight: Copper Processing

Posted by H&P Blog on Wed, Jul 18, 2012 @ 11:01 AM

The copper processing industry refines its metal from ores or scrap.  Its leading consumers are wire mills and brass mills, which use the metal to produce copper wire and alloys, respectively.  Copper's end uses include construction materials, electronics and transportation equipment.  Once refined, the metal can be used as a powder in automotive, aerospace, electrical and electronics equipment, and in various chemical and medical processes.

H&P Process Spotlight: Wood Torrefaction

Posted by H&P Blog on Wed, May 16, 2012 @ 10:37 AM

Torrefaction is a process by which wood biomass is transformed into something that looks and acts much like coal.  Through this process, moisture is removed from the wood, along with other non-essential fibers and substances.  All that remains of the original wood is a smaller, blackened solid which can be made into dense bricks of bio-coal.  This man-made coal can provide energy rates of up to 25 GJ/ton.  Naturally occurring coal generally provides 30 GJ/ton.
