Overview
From pebble lime to peanuts, from coal to baby powder - and everything in between pneumatic conveying has long been a popular choice for moving bulk materials, either from storage facilities to a process unit, or between process units. Two most distinct categories of pneumatic conveying can be described as either dilute-phase or dense-phase systems. These have been developed over the past few decades to take advantage of the different behavioral properties of bulk materials and also to meet the increasingly demanding requirements of industry in the areas of system reliability, product quality control and energy efficiency. In particular, dense phase operation (with its relatively low velocities) is usually preferable if the conveyed material degrades easily or is highly abrasive.
Selecting the correct pneumatic conveying regime for your requirements is a vital decision for a successfully designed system. This 5-hour course presents an overview of pneumatic material handling system and summarizes the main hardware and technology attributes for efficient conveying.
Process/production personnel, mechanical and chemical engineers, operation and maintenance engineers in the following industries will benefit from the information provided in this course: chemical, petrochemical, agro-chemical, and specialty chemical, biotechnology, pharmaceuticals and cosmetics, food processing, mining/mineral processing, plastics processing, bulk storage, pulp and paper.
The reader must take a multiple-choice quiz consisting of twenty five (25) questions at the end of this course to obtain PDH credits.
