Frac Sand Dryers: Analyzing the Merits of Rotary and Fluid Bed Styles

Posted by H&P Blog on Wed, Jul 15, 2015 @ 09:30 AM

Frac sand plays the essential role of preventing fractures in oil and gas wells from closing prematurely.  Fluid bed and rotary dryers are used to thermally treat the sand to remove impurities before it is injected into the fissures.  Both methods of frac sand drying have their merits, and a decision between them ultimately comes down to equipment costs and maintenance issues. Heyl & Patterson recently explored the two types of frac sand dryers in an article published in Process Heating magazine's June 2015 issue, entitled "Using Rotary and Fluid Bed Dryers for Drying Frac Sand."  The article was featured as the cover story.

Foundry Sand Reclamation via Thermal Processing

Posted by H&P Blog on Wed, Jul 01, 2015 @ 09:00 AM

Foundry sand, or molding sand, is essential to the metal casting industry.  It consists of a clean, uniformly sized, high-quality type of silica sand that can be used to form molds for ferrous and nonferrous castings.  Formed metal objects ranging from engine parts to building plaques are made with two halves of a sand mold that produce a pattern, and molten metal is then poured to into holes to fill the void inside.  Silica's high fusion point and low rate of thermal expansion produce sturdy molds compatible with a wide range of pouring temperatures and alloys.  Once the casting process is complete, the molds are broken apart and the foundry sand is recycled to produce new molds.

Heyl & Patterson to Present on Frac Sand Drying at Frac Sand Insider

Posted by H&P Blog on Wed, Nov 12, 2014 @ 10:21 AM

Hydraulic fracturing, also called "fracking" or "fracing," permits access to vast amounts of natural gas that had previously been unreachable.  A well is first drilled into a rock formation, and a high-pressure fluid containing a propping agent, or proppant, is then injected into the well.  This mixture typically consists of water, sand and a proprietary blend of chemicals.  Once injected into the well, the proppant prevents the fracture from closing, which allows the gas to flow freely.

A Guide to Frac Sand Drying For Use in Hydraulic Fracturing

Posted by H&P Blog on Wed, Jun 11, 2014 @ 09:41 AM

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.

Heyl & Patterson to Host Lab Tours for Frac Sand Insider Conference

Posted by H&P Blog on Wed, May 29, 2013 @ 09:57 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, 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 remains 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: 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.
