Since 1875, the United States has been one of the world's main steel producers. Steel has been an important factor in the American economy for over 100 years, providing jobs to many generations of American families, and it continues to be a booming industry today. Production of steel takes place in two different ways. One method uses integrated smelting involving a blast furnace, followed by a basic oxygen furnace, and the other involves an electric arc furnace.
A tailings pond is a temporary storage area for the leftover by-product materials from oil sands, shale gas and coal ash operations, and is often a discontinued mine pit that has been re-engineered with a dam and dyke system. The contents of the pond is a slurry, with large volumes of water, sand, clay, residual hydrocarbons, heavy metals, naphtha diluents and naphthenic acids, which are known as tailings. The various materials settle to different depths, but they can all be dredged and dried to reduce their volume and eliminate moisture.
Bulk material handling equipment has evolved over many years. Some of the materials being transported have changed, such as specialized sands used in the oil and gas industry and new potential energy sources such as biomass, plus the volumes have increased and the terminals have become much more sophisticated. Even so, many of the basics in the industry have remained the same over the years.
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.
Frac sand is used in hydraulic fracturing for the recovery of gas and oil from previously inaccessible deposits and dormant wells. In order to be used, it must first be dried and refined after it is mined. Specifically, in order for the desirable sand to be separated from unusable impurities, it must be washed and then dried using specialized thermal processing equipment before it is transported to the sifting process.
According to software developer Symantec, organizations understand that “app culture” is not going away, and in order to avoid falling behind, they need to integrate themselves into that world. iPhone and Android operating systems have significantly changed how cellphones function, making them about productivity in addition to communication. Currently, 71% of companies are either investigating or are actively deploying their own mobile applications.
A powder is a bulk solid material composed of a large number of very fine, dry particles that flow freely when held at an angle. These substances are a type of granular material that have finer grain sizes, so they have a greater tendency to clump when flowing, as opposed to coarser materials that do not form clumps except when wet. Due to their small particle size, powders are more cohesive and more easily suspended in gas.
FOR IMMEDIATE RELEASE: Pittsburgh, PA – Heyl & Patterson Inc., a world leader in bulk material handling systems and thermal processing equipment, today announced the signing of an exclusive license agreement with ELB Engineering Services (Pty) Ltd. (ELB), a bulk material handling provider based in Johannesburg, South Africa.
The current version of the Heyl & Patterson website went live in 2010, and it included a woman whose identity has been shrouded in mystery. Some believe she is related to the company's owners, and others believe she was simply hired as a model to welcome vistors to a website. Nothing could be further from the truth. Her name is Heyland Patterson, and this is her story.
According to the U.S. Energy Information Administration, about 68% of the country's electrical grid is generated by fossil fuels. As of 2013, about 37% of our energy comes from coal, 30% from natural gas, 30% from nuclear, 7% from hydroelectric and 5.4% from other renewables such as wind (3.46%), biomass (1.42%), geothermal (0.41%) and solar (0.11%). An additional 1% is generated by petroleum, and less than 1% by other gases such as waste heat from blast furnaces.
