6 Reasons to Pneumatically Convey Frac Sand | Frac Sand Conveying FAQs
PDF Version Visit our proppant/frac sand page for more information and our video. Mechanical conveyors have been the most commonly used method to convey frac sand in production facilities across the country. Although these systems have been the historical solution to frac sand conveying, they are limited in how they solve proppant handling issues like plant flexibility, dusting, and downtime due to maintenance. Nol-Tec Systems offers an alternative solution to frac sand conveying that can address these issues: pneumatics.

Dense Phase Conveying Solutions for Salt Handling
PDF Version An international food manufacturer recently expanded one of its existing plants in the Midwest to accommodate a new food production operation. Part of the new operation involves conveying granular salt from a bulk silo to two smaller receiving bins connected to volumetric feeders. The company was dissatisfied with its salt-conveying equipment in other parts of its operations, so it worked with a current equipment supplier to find a solution. Conveying System Problems The company uses dilute-phase vacuum conveying systems in its other plants to convey salt and other dry ingredients.

Dilute Phase vs Dense Phase Conveying Overview
Outline of Pneumatic Conveying Systems This article provides some basic information about pneumatic conveying system types, operation, and applications. A pneumatic conveying system transfers powders, granules, and other dry bulk materials through an enclosed horizontal or vertical conveying line. The motive force for this transfer comes from a combination of pressure differential and the flow of air (or another gas) supplied by an air mover, such as a blower or fan. By controlling the pressure or vacuum and the airflow inside the conveying line, the system can successfully convey materials.

Fine Particulate Collection Using Dry Electrostatic Precipitators
Robert A. Mastropietro Lodge-Cottrell Inc. 2319 Timberloch Place, Suite E The Woodlands, TX 77380 INTRODUCTION Potential legislation concerning fine particulate or PM-2.5 (particulate matter less than 2.5 microns) has been under discussion for several years. Atmospheric air quality is the issue that legislation is trying to address. However stack emissions from stationary sources are only one contributor to atmospheric PM-2.5. Since PM-2.5 can come from a wide variety of sources (road dust, automobile exhausts, farm fields, acid condensation, etc.), PM-2.5 from stationary sources is only one source contributing to total atmospheric PM-2.5.

Fly Ash Resistivity with Injected Reagents and Predicted Impacts on Electrostatic Precipitators
Prepared by, Robert Mastropietro Vice President – Technology Lodge Cottrell Inc. Executive Summary Electrostatic precipitators (ESP’s) , which are particulate collectors, are now used as part of the flue gas scrubbing strategy. In these combined systems, a particulate reagent is injected into the flue gas ahead of the ESP, to either neutralize or absorb a gaseous pollutant.

How to Convey Sand & Silica | Conveying Silica & Sand
What Are Sand & Silica Used For? Sand is a naturally-occurring granular material that is finer than gravel, but more coarse than silt. It can have differing chemical compositions depending on local mineral sources and conditions. The most common component of sand in inland and non-tropical coastal areas is silica, usually in the form of quartz; coastal sand is commonly composed primarily of calcium carbonate. Sand has countless uses, from agriculture to glass manufacturing to hydraulic fracture drilling, or fracking, where it is known as “ frac sand ”.

How to Pneumatically Convey Various Materials in Dense Phase
Are you interested in switching to dense-phase pneumatic conveying? Or have you found that your material is difficult to convey in dense phase? Read this article for tips on how to convey carious materials in a dense phase system. Dense phase (slug-flow) pneumatic conveying can provide several benefits. The method moves material at relatively low velocity, which prevents material degradation and equipment wear. Dense-phase conveying also reduces segregation and promotes flow at lower air volumes, making it more efficient per pound of material conveyed than higher volume dilute-phase (stream-flow) conveying.

Impacts of Hydrated Lime Injection on Electrostatic Precipitator Performance
ASTM Symposium on Lime Utilization June 28, 2012 Robert A. Mastropietro Vice President of Technology Lodge-Cottrell Inc. 2319 Timberlock Place – Suite E The Woodlands, Texas 77380 USA Abstract Electrostatic precipitators (ESPs) , which are particulate collectors, are now used as part of the flue gas scrubbing strategy. In these combined systems, hydrated lime is injected into the flue gas ahead of the ESP, to either neutralize or absorb a gaseous pollutant.

Pneumatic Frac Sand Handling and Conveying Solutions
This article discusses the ability of pneumatic conveying to meet and exceed the needs of the frac sand and proppant conveying market. Demand for frac sand has never been higher and its use continues to grow.
