Ethanol Facility - 100 Million Gallons per Year
357 MBtu/hr Fluidized Bed Energy System
(Cattle Manure and Cotton Gin Waste)
267,000 lb/hr steam, 425 psi, 725 deg. F

Project Description
This multi-fuel EPI energy system is designed to convert one billion pounds of cattle manure a year into usable energy for an ethanol plant.  By using a renewable fuel (cattle manure) to create a renewable fuel (ethanol), Panda Ethanol is eliminating exposure to natural gas pricing volatility, conserving the energy equivalent of 1,000 barrels of oil a day and creating a significant market advantage in their ethanol production costs.  In addition, by disposing of the manure in a clean environmentally friendly manner, Panda is addressing the environmental hazards related to field application of cattle manure in the Hereford, Texas region.

This first-of-its-kind energy facility provides Panda with one of the most fuel-efficient ethanol refineries in the nation and the largest biomass-fuel ethanol plant in the United States.  Panda is one of a few ethanol facilities that is not severely impacted by dramatic increases in natural gas costs.

The system is designed to operate on 100% cattle manure, or a mixture of manure and many other fuels.  EPI's bubbling fluidized bed energy system is the first commercially successful system to operate on 100% cattle manure.

In this process, relatively wet cattle manure is introduced into a bubbling sand bed which is maintained at a precise temperature.  This bed effectively drives off the moisture and converts the organic materials into a usable energy in the form of hot gas.  The gas is run through a specially designed boiler that produces steam for use in the ethanol process.  The result is a clean, odor-free conversion of cattle manure, or other biomass materials, into clean usable steam.

Scope of Supply
EPI's contract includes all of the equipment from the fuel receiving/storage/handling systems to the boiler island and stack.  The system includes EPI's selective non-catalytic reduction system for NOx control, a dry scrubber for SO2 and HCl control and a baghouse for the final particulate capture.

The multi-fuel capability of this system makes it a shining example of EPI's latest "flexible fuel" energy systems.
