A great article talking about the Colombo Energy Wood Pellet Plant in this month’s Wood Bioenergy Magazine, including a mention of Mid-South’s efforts. This was a good project and Mid-South Engineering is happy to have been chosen to be part of the team.
Check out the Wood Bioenergy Magazine here.
Mid-South Engineering Co., an Arkansas-based, full service consulting engineering firm announces the opening of its fourth office located in Orono, Maine. The new office, led by Walter Goodine, Director of Operations, allows Mid-South to better respond to its client’s engineering needs in New England and Maritime Provinces. Orono, home of the University of Maine, is just north of Bangor.
“The addition of this location supports our firm’s commitment to build on the success we have seen in the New England area,” states Mid-South President, Jeff Stephens. “The new office location is convenient to the building products, paper and bio-energy markets we serve and provides ready access to the professional talent to grow our staff.”
About Mid-South Engineering –Founded in 1969, Mid-South is a full service, consulting engineering firm that provides a broad range of professional engineering services. Our multi-disciplined staff has served state and local governments as well as industrial and commercial clients with a particular expertise within the building products industry.
Join Mid-South Engineering on June 14-16, 2017 at the Georgia World Congress Center in downtown Atlanta for the 2017 Forest Products Machinery & Equipment Expo.
Sponsored since 1950 by the Southern Forest Products Association, the Forest Products Machinery & Equipment Exposition has provided the a venue for equipment manufacturers to display their products and services to the wood processing industry.
Check us out at Booth #1836. We will see you then!
Join us on April 25-27, for the 2017 Northeast Biomass Heating Expo. The region’s largest biomass heating conference will be held at the Sheraton Hotel and Conference Center in Burlington, VT.

Approaches Used for Energy Studies
by Eldon Doody, P.E.
Our team utilizes a comprehensive approach to energy evaluations to ensure the most suitable and cost-effective outcomes for our clients. Our energy studies typically involve the following steps:
Site Survey and Information Gathering:
The first step in each energy study is a visit to the client’s facility by key staff members. One purpose of the site visit is to gather and review documentation such as drawings and historical operating data. The site visit allows our engineers to get a firsthand look at the facilities and equipment, to assess existing conditions and to determine opportunities for improvement. It also allows us to review potential locations for future equipment.
Perhaps most importantly, the site visit provides an opportunity for our staff to meet with facility operating and maintenance personnel to obtain their valuable input and ideas as to the facility’s issues, limitations and potential.
A key component of each energy study is the development of an energy model that represents all the energy inputs and outputs for both the existing facility and for proposed changes. We strive to have several years, preferably five years, of data to input into the models. This includes fuel consumption, electrical consumption, thermal and electrical energy in-house generation, etc. The spreadsheet format allows our clients and us to experiment with various “what-if” scenarios. Models are developed using Microsoft Excel, have the advantage of being widely used by technical personnel, and are easily modified by us or for use by others. The model includes all the major elements of a steam plant, including: Boilers, Steam Headers, Condensate Headers, Power Turbine-Generators, Pressure Reducing Valves, Feedwater Pump Turbines, Boiler Fan Turbines, Deaerators, Feed Water Heaters, De-superheaters, Air Heaters, Blow Down Flash Tanks, Blow Down Condensate Heat Recovery, and Cooling Towers.
Your Piping Systems May Deserve a Second Look
by Rob Bullen, P.E.
Just about every building or facility has that one thing that seems to be “out of sight – out of mind…” and most people are just happy to let that be. The item that I am referring to here is piping, and to be honest, it is more than a little bit errant to call it that one thing. The truth be told, most facilities have many piping systems: Potable water, process water, fire protection water, sanitary sewage, storm water, compressed air, natural gas…and the list goes on.
Most of the time, these systems never get a second look. That is until there is a problem. While piping systems do not generally have an awe-inspiring appearance, and rarely even seem noteworthy, many of these systems have the ability to singlehandedly bring a plants production to a halt.
Common Hood Mistakes
by David Colborne, Project Manager
In most industrial environments, the air pollution control system is underappreciated and given very little attention. It is the non-productive portion of the operation, so many are uninterested in investing money for a properly designed and efficiently operating air pollution control system. That baghouse out back is considered to be a necessary evil – something that is needed for worker safety or environmental compliance, but not an area where most plants want to focus their capital.
Moreover, when it comes to industrial ventilation systems, frequently most of the attention is on the ductwork and the pollution control device. The important element which is often overlooked and doesn’t get enough focus is the hoods and the hood design. If you cannot capture the dust or the fume at the source, it doesn’t matter how well designed the ductwork is or what the transport velocity measures or how efficient the filtration device is. Additionally, as is commonly explained, you only get one chance to capture the dust at its point of generation; once the dust gets away from the source and becomes fugitive dust, it’s only a matter of where it will settle.
This article will look at the most common hood mistakes that we see during our plant visits, why they are a problem and how they can be done correctly. Perhaps you’ve seen these hoods in your travels as well.
