Heyl & Patterson to Present on Thermal Processing of Biomass Feedstocks at the International Biomass Conference

Posted by Chelsea Finlay on Wed, Mar 23, 2016 @ 08:48 AM

The International Biomass Conference is fast approaching, and the excitement is building.  Last year, biomass enthusiasts from more than 34 countries met in Minneapolis to take the temperature of the Biomass Industry. This year the industry is heating up as we prepare to reconvene in Charlotte to share updates, innovation and all things biomass.

Characteristics and Benefits of Torrefied Wood

Posted by H&P Blog on Wed, Oct 21, 2015 @ 09:24 AM

The daily news reverberates with discussions about the adverse global impact humans have on the environment.  Scientists study how we can lessen it, by reducing our individual carbon footprints and making the overall move to green energy sources.  Finding a clean, efficient and relatively inexpensive replacement for the world's ubiquitous use of coal in fossil fuel power plants is a massive part of that discussion.  Some companies are considering the replacement of coal with a form of processed biomass material known as torrefied wood, and there needs to be an understanding of its storage characteristics.

Heyl & Patterson Blog Celebrates Five Years

Posted by H&P Blog on Wed, Jun 17, 2015 @ 09:44 AM

The word "blog" is short for "web log," and is a website with posts providing commentary on a particular subject, much like a newspaper editorial column.  Blogging grew out of the burgeoning digital communities of the 1980s, which included Usenet, CompuServe and Bulletin Board Systems (BBS), and featured running commentary about various topics.  Early versions were a form of web diary that kept an intimate account of the authors' personal lives, and these ultimately evolved into the distinct class of online publishing we know today.  According to the web platform Technorati, there are now over 2.7 million blog posts published each day, and other recent statistics show that there are over 172 million Tumblr blogs and 75.8 million WordPress blogs in existence.

Torrefaction Equipment Converts Wood Biomass into Biocoal

Posted by H&P Blog on Wed, Apr 08, 2015 @ 09:40 AM

Biomass co-firing is the burning of fossil fuels in coal-fired power plants in conjunction with forestry and agriculture residues, animal manure, wood wastes, such as sawdust or bark from the timber industry, waste wood and dedicated energy crops. Co-firing increases the amount of renewable biomass in the global energy mix and also reduces greenhouse gas emissions. The technologies include biomass that is jointly milled with coal and fed into the same boiler, biomass that is converted into a fuel gas and then burned with coal in the same boiler, and biomass in a separate boiler that supplies steam to a coal cycle.

Materials and Applications for Rotary Calciners

Posted by H&P Blog on Wed, Aug 27, 2014 @ 09:45 AM

Calcination is loosely defined as thermal processing done at elevated temperatures to change the properties of a given material.  Calcining is often applied to ores and other solid materials to bring about a thermal decomposition, phase transition or removal of a volatile fraction.  The calcination process normally takes place at temperatures below the melting point of the material being calcined.

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.

Torrefaction Talk at the 2014 International Biomass Conference

Posted by H&P Blog on Wed, Mar 12, 2014 @ 10:07 AM

In the early 1980s, the domestic steel crisis left about widespread unemployment across the Iron Range area of Minnesota, and even the state's logging, pulp and paper industries faced global competition.  To counteract these threats and avoid similar issues in the future, a group of researchers, legislators and community members developed the Natural Resources Research Institute (NNRI) within the University of Minnesota Duluth to study the economic impact and sustainability of Minnesota’s minerals, forest products, peat, biomass and water-related industries.

Heyl & Patterson to Speak at Activated Carbon Conference

Posted by H&P Blog on Wed, Sep 25, 2013 @ 10:24 AM

Activated carbon is a form of carbon that is riddled with tiny pores that increase its surface area, making more of it available for chemical reactions.  This porous, highly adsorptive material is used to remove color or impurities from liquids and gases, in the separation and extraction of chemical compounds, and in the recovery of solvents.  In other terms, activated carbon is used in water filtration, gas purification, sewage treatment and metal extraction.  It is most commonly found in the filters of aquariums, respirators and gas masks, and is used to treat poison following oral ingestion.
