- Ongoing Project Delivery
During 2008-13, Burns & McDonnell provided site-based project delivery services to the National Corn-to-Ethanol Research Center in Edwardsville, Ill. Our engineers worked on dozens of plant initiatives, retrofits, upgrades and expansions involving multidisciplinary design, program management and design/build delivery of larger projects. Services were provided from conception through start-up/commissioning.

Advanced biofuels initiative
Burns & McDonnell provided a feasibility study to incorporate feedstock prep, pretreatment, hydrolysis and fermentation, product recovery, utilities, and facilities for the processing of cellulosic materials. NeaTech was used as a subconsultant to provide industry and academic studies.
Burns & McDonnell provided services from conception to start-up/commissioning to retrofit a front-end corn fractionation system. The project included demolition of existing process systems, installation of the corn fractionation system, and facility enhancements to isolate the front-end systems from the plant.
Burns & McDonnell engineered and detailed utility and support systems for the reactors installed as part of the project. A bio-sump and pump were designed, detailed and installed into a mat-style floor. The north wall of the room was modified to include an overhead coiling door.
Burns & McDonnell provided an HVAC study to provide cooling to the Fermentation Suite.
Burns & McDonnell provided FEP-1 and FEP-2-level services to increase capacity of the distillation and dehydration system. FEP-1 identified bottlenecks and proposed solutions to increase capacity. FEP-2 simulated the concept design, generated a process flow diagram, determined rough equipment sizing, checked existing equipment and piping, and generated a factored cost estimate.
Burns & McDonnell engineered and designed vent condensers to control vapor phase emissions from liquefaction and fermentation. This project included an automated CIP delivery system and a mezzanine.
Burns & McDonnell defined the performance requirements for a plate and frame heat exchanger for use as the heating element in the evaporation system to minimize system hold-up volume. This project provided a new recirculation system, complete with pump, piping and instruments and controls and modified an existing mezzanine.
Burns & McDonnell engineered and detailed a new mixing and pumping system for the fermenters. The new systems used rotary positive displacement pumps and tank mixing eductors.
Dryer feed conditioning upgrade
Burns & McDonnell detailed the reconfiguration of the equipment feeding the rotary drum dryer. This project included replacement of the mixer and new screw conveyors.
Burns & McDonnell specified casework, countertops, sink, faucet, and accessories to convert an office to a lab. A sump pump was provided to collect liquid waste from the sink and pump to a bio-sump inside of the plant for special handling.
