2. Labor-- At low production rates labor can be a significant operating cost.Usually, a successful small operation cannot afford to have a person in attendance full-time (for example, assuming a labor cost of $7.00 per hour and a 10 gal/hr production rate, the operating cost of

Disruption free operation of existing ethanol plant ~ 280 ton/day biomass required • Enable biomass feedstock flexibility wood, cobs, stover, grass, oil or glycerin (liquid injection) • Utilize existing energy assets Retrofit existing Gas Fired appliances Distributed gas integration network required to
For a 100,000 pound per hour steam boiler, operating costs can be reduced by more than 50 percent depending on the cost of fuel. One option would be to use a gasifier to produce syngas or producer gas, which could be burned in a retrofitted existing boiler. An example of such a plant is Chippewa Valley Ethanol Corp. in Benson, Minn.
Brazil is the world's second largest producer of ethanol fuel.Brazil and the United States have led the industrial production of ethanol fuel for several years, together accounting for 85 percent of the world's production in 2017. Brazil produced 26.72 billion liters (7.06 billion U.S. liquid gallons), representing 26.1 percent of the world's total ethanol used as fuel in 2017.
- Operation costs are the expenses related to the operation, maintenance and monitoring of the plant - Operation costs can amount up to 50 % of the total annual costs. - The evaluation of operation costs during the evaluation of of process alternatives is of crucial importance.

Table 2.5 reviews the operating costs for sugarcane to ethanol and starch ethanol dry milling biorefineries. While sugarcane ethanol biorefineries pay nearly twice as much in annualized costs for feedstock than do corn ethanol biorefineries of comparable ethanol output, they also derive significantly more revenue from by-product credits in the form of electricity and crystallized sucrose sales.
