SOLIDS PROCESSING: Blending and Segregation and Their Effects on Product Quality
Chem Engineering Educational Series
Time: 9:00 am - 12:00 pm Room: TBD Speaker(s): Eric P. Maynard About the Instructor(s): Description: Why is this topic important to industry?
Obtaining a uniform blend of dry bulk solids is a problem faced daily by engineers and operators in industries as varied as chemicals, pharmaceuticals, foods, plastics, and battery production. Even if a "good" blend is achieved, the next problem is how to maintain that blend through downstream equipment. Poor blending, or the inability of maintain a blend (i.e. segregation) at the point where it is needed, is always costly in terms of rejected material, extra blending time, and defective end products. This topic is important to industry because once the mechanisms of blending and segregation are understood, they can be used to analyze particle segregation problems and to determine ways to eliminate such problems.
What will be covered in this session?
Advantages and disadvantages of various types of bin flow patterns
Analysis of blend uniformity
Sample collection, splitting, and analysis
Solids flow problems, such as no flow and segregation
Flow patterns within a bin or blender
Effects of bin and blender design on flow patterns
Common mechanisms of particle segregation
Methods to quantify segregation tendencies
How flow patterns affect segregation
How to modify/design solids handling equipment to minimize segregation
Blending mechanisms and types of blenders
Attendees' questions
Who should attend?
Design engineers, researchers and plant personnel interested in developing an understanding of blending and segregation and want to ensure or improve the uniformity of their final product.

WIRELESS: Wireless and Asset Management - Small Investments, Quick Returns
Chem Engineering Educational Series
Time: 9:00 am - 11:30 am Room: TBD Speaker(s): TBD About the Instructor(s): Description: The Chemical Process Industries are currently emerging from triage mode, still focused on keeping costs down and improving revenues. And in many cases, they are doing it all with a reduced workforce. This short-course will help attendees identify the low-hanging fruit in their plants that are ripe for improvement. The focus will be on integrated solutions, such as wireless and asset management, that quickly lower total operational and life-cycle costs without the requirement for huge, upfront investments.
Up to now, there has been some hesitation to fully embrace wireless technologies due to the absence of standardization and the potential long-term complications that might ensue. But with the release of WirelessHART and the impending ISA 100 standard, end users will be able to select products from multiple vendors that support the network they've chosen and know that the instruments will work together.
Who should attend:
This course is for end users who are completely new to industrial wireless and those who have already gotten their feet wet and are ready to take the next step.
What attendees will learn:
Explore the possibilities in mobile operator applications. Learn how video can serve as a new process sensor, vibration sensors can improve rotating equipment health and discover many other applications that can improve plant efficiency, reliability and safety.

SOLIDS PROCESSING: Selection of Screws, Belts, and Rotary Valve Feeders for Reliable Flow and Rate Control
Chem Engineering Educational Series
Time: 1:00 pm - 3:00 pm Room: TBD Speaker(s): Eric P. Maynard, Jenike & Johanson Inc. About the Instructor(s): Description: Why is this topic important to industry?
Feeders are used to control the rate of material discharge from a bin, hopper, silo or bunker outlet. Unfortunately, the mechanisms governing operation of feeders under bin outlets are not well understood in the bulk solids handling industry. As a result, many existing screw and belt feeders, as well as a myriad of other types of feeders, do not operate properly. This often leads to excessive power consumption, abrasive wear, particle attrition and, even worse, unreliable material flow. This topic is important to industry because methods are available to minimize, if not eliminate, process irregularities caused by improper design of volumetric and gravimetric bulk solids feeders.
What will be covered in this session?
Advantages and disadvantages of various types of bin flow patterns
Difference between a feeder and a conveyor and importance of making feeder design compatible with bin design
Design techniques for screw feeders under elongated outlets
Single vs. multiple screws and U-trough vs. Vee-trough
Screws used for sealing against gas pressure gradients
Design techniques for belt feeders under elongated outlets
Comparison of screw, belt and rotary valve feeders
Limitations on use of vibrating pan feeders and feeders for special applications
When to use a gravimetric feeder and comparison of various types of gravimetric feeders
Attendees' questions
Who should attend?
Design engineers and plant personnel who are experiencing feeder problems and/or who want to ensure controlled flow of bulk solids from new or existing bins and hoppers.

COST-EFFECTIVE CONSERVATION: Biomass Energy - Practical and Cost-effective Applications in the CPI
Chem Engineering Educational Series
Time: 8:45 am - 9:45 am Room: TBD Speaker(s): Thomas F. McGowan, TMTS Associates Inc. About the Instructor(s): Description: For the Chemical Process Industries, biomass and alternate fuels offer cleaner, renewable ways to produce energy, can greatly reduce operating costs, and are considered carbon neutral. Wood-based and agricultural biomass fuels are becoming a common source of alternative fuels. They are used to co-fire coal boilers at power plants and pulp and paper plants, and are used in standalone independent power production facilities of 60 MW and more. When compared to coal, biomass produces cleaner energy at substantially lower costs, because it has much lower sulfur content and is cost-efficient. The current push is by independent power producers and electric utilities, which are planning 50-100 MW wood fired plants in forested areas, as well as cogen use by industry for steam and power.
What Attendees Can Learn:
This presentation covers the subject from the forest to the stack. Practical information is offered, including diagrams and photographs of actual equipment and installations, to provide attendees with an understanding of these environmentally friendly fuels alongside step-by-step guidance for converting these fuels into energy. Capital, operating and production costs are covered. Air pollution control is addressed, and basics of Greenhouse Gas calculations methods are explained. Emphasis is on direct combustion of wood and biomass, but production of liquid fuels from biomass is also covered, and costs are compared to competing alternate fuels, such as reclaimed oil, used tires, cooking oil, solid wastes, coke, coal, gas and oil. The goal is to supply the attendee with all the information needed to chose and implement an energy system to match their organization’s needs.
Who Should Attend:
The major target audiences include CPI managers, engineers, environmental, health and safety professionals, and plant workers who work for utilities, industrial firms, A&E firms, operating firms, consultants, CEOs and CFOs and regulators.
9:00 am
SOLIDS PROCESSING: Preventing Bulk Solids Caking and Particle Attrition
Chem Engineering Educational Series
Time: 9:00 am - 11:00 am Room: TBD Speaker(s): Eric P. Maynard, Jenike & Johanson Inc. About the Instructor(s): Description: Why is this topic important to industry?
Powder caking, whether or raw material in bags or drums, or during storage of in-process material, is a major cause of problems. Being able to predict the conditions under which caking occurs, as well as identifying the material properties that lead to caking is necessary for avoiding or solving this problem. This session will discuss a novel approach that utilizes both micro and macro properties of powders to identify the causes of caking and develop solutions. Properties discussed will include particle surface composition and hardness, moisture sorption/desorption characteristics, particle strength and size distribution, a powder's response to temperature and humidity cycling, and the change in shear strength as a function of time consolidation and environmental conditions.
Particle degradation, or attrition, can also be a major concern during the handling of friable bulk solids. Particle attrition can negatively impact product quality, performance, or induce bulk solids flow problems. Understanding the causes of particle attrition, as well as common solutions which can be employed to minimize, if not eliminate this problem, will be covered in this session.
What will be covered in this session?
Common mechanisms of caking
Review of caking testing techniques
Discussion of micro and macroscopic powder properties that affect caking behavior
Review of external factors affecting caking
Common mechanisms of particle attrition
Review of attrition testing techniques
Discussion of factors that affect attrition behavior
General recommendations to prevent or minimize damage to particles
Who should attend?
Design engineers, researchers, product formulators, and plant personnel interested in developing an understanding of particle caking and want to ensure caking does not occur with their products. Plant personnel interested in developing an understanding of particle attrition and want to ensure damage does not occur to their products will collect valuable information in this informative session.
10:00 am
