Mr. Wiley is a Mechanical Engineer, residing in Louisiana, engaged in contract engineering in the forest products arena. His education includes Bachelor’s and Master’s degrees in Wood Science and Technology from Louisiana State University. He also holds a Mechanical Engineering degree from Texas A&M University. He is a Professional Engineer, registered in Louisiana and Texas.

His work experience includes seven years of research in applications of wood, six years as a plant engineer at a large plywood and lumber mill complex, and 33 years of consulting engineering, primarily focused on design of forest products processing facilities. He has worked as lead Mechanical Engineer in detail design of conveyors and hydraulic and pneumatic equipment in support of sawmill operations. He has participated in overall layouts, process flow planning and equipment selections for all types of Forest Products plants. In addition, he has served as lead Mechanical Engineer in diverse chemical projects and compressed natural gas (CNG) stations.

Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.

Course Description:

Many manufacturing facilities use large quantities of compressed air. In designing such facilities, the Consulting Engineer will often be required assemble a bid package for the compressed air system. To do this, he must determine the Scope of Work, then size the equipment and write specifications. The purpose of this course is to provide instruction on completing these steps. The course is written for design of materials-handling facilities that do not require large amounts of instrument air, but rather use compressed air for power, cleaning and other unit operations. Specifically, it is written from perspective of the authors' experience in designing forest products manufacturing facilities.

On completing this course, the student should be able to:

Calculate the basic compressed air requirements of the process.
Calculate the design compressed air requirement for the plant.
Determine the equipment supply requirements.
Name some advantages of rotary screw compressors over reciprocating compressors.
Describe the functions of an aftercooler.
Name two types of dryers commonly used in forest products manufacture.
Describe three types of regeneration systems for desiccant dryers.
Name three purposes for compressed air receivers.
Estimate the required size of compressed air receiver.
Discuss the need for an oil/water separator with the client.
Calculate the expected oil concentration in the condensate leaving the aftercooler.

249-Bulk Silos for Biomass Facilities

Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.

Course Description:

Bulk silos are an essential part of most biomass and some forest products facilities. They are used for intermediate storage of partially processed raw material and storage of final product. The purpose of this course is to familiarize the engineer with the use of these silos, so that he can adequately specify them and provide for them in a plant layout.

On completing this course, the student should be able to:

Determine the volume and weight storage requirements.
Understand choices of different wall materials and constructions.
Specify accessories that will be needed, including fire protection requirements and explosion protection.
Understand the concept of "aspect ratio" of a silo.
Understand the need for "mass flow" from a silo.
Understand the difference between screw reclaim and passive reclaim.
Estimate the working volume, height and diameter of a silo for a proposed application.

267-Biomass Process Flow Calculations

Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.

Course Description:

Process flow calculations are an essential part of any biomass project. They provide an aid in firming-up the basic process, sizing equipment and estimating the project. The calculations however are complicated by the fact the certain variables such as daily operating hours, bulk density and moisture content vary as the material progresses through stages of the process. This course presents a methodical approach that can render the calculations relatively simple and minimize opportunities for errors in complex projects.

On completing this course, the student should be able to:

Understand the difference between block flow diagrams and process flow diagrams.
Understand the basic methodology for performing process flow calculations.
Understand the need for storage volume calculations as part of the process flow calculation procedure.
Understand how to predict fuel requirement to a dryer.
Understand how to calculate annual uptime rates.
Understand the difference between dry basis and wet basis moisture contents and how to convert between them.
Understand the advantage of working with "oven-dry" bulk density.
Understand the considerations involved in selecting design factors.
