Together We Can: U.S. Water and Ethanol Industry Exports

Expansion of the volume of ethanol exported to the rest of the world is critical to profitability and expansion of the industry. Exports continue to set records (927 million gallons in the first seven months of 2018) but can be limited by challenges created by inconsistency in quality specifications and the methods used to guarantee them. U.S. Water has stepped forward in the last two years to help our [...]

Considering an Ethanol Plant Expansion?

Many biofuel plants are expanding operations to increase ethanol production. Often when plants move forward with expansion efforts, the adverse impact on system efficiencies, such as cooling, is overlooked. Without proper evaluation of the existing cooling system operation, plants could spend additional capital on an unnecessary cooling tower expansion or experience an increase in operational costs if the existing [...]

U.S. Water's ProClean AB 1000 Optimizes Ethanol Producer's Fermentation Process and Reduces Treatment Costs

Even with quality cleaning practices in place, there is a risk of bacterial infection during the fermentation process of ethanol production. When bacteria are present, it can inhibit yeast productivity and loss of alcohol production can occur. Many ethanol producers utilize an antibiotic program to control bacteria growth and optimize product yields. A Midwest ethanol producer was utilizing a competitor’s [...]

Custom Plant Controls Upgrade Optimizes Aging Ethanol Facility Performance

Multiple Midwestern ethanol facilities within the same organization were experiencing controls failure due to aging PLC and HMI equipment. Current plant control equipment was more than ten years old and had reached end of life. The outdated equipment caused plant shutdowns and a loss in production, which can cost up to $10,000 per hour. U.S. Water recommended an integrated controls upgrade solution to prevent future [...]

Interpreting Tier III Compliance

The ethanol industry has been anticipating this for a couple of years, but it still snuck up on some of us – the EPA (Environmental Protection Agency) Tier III compliance is required as of January 1, 2017. Fuel ethanol producers need to be aware that they must be able to demonstrate that their product consistently meets the new 10 parts-per-million (ppm) organic sulfur standard. Similar to other pending [...]

U.S. Water’s Unique Sulfur Control Solutions

Let's start with the scrubber. Aldehydes, primarily acetaldehyde, in fermentation gas are considered to be “hazardous air pollutants (HAPs)” by EPA. Aldehyde control is often based on sulfites, which react with the aldehydes, making them “scrubbable”. If you use more than required sulfur dioxide (SO2) gas can freely pass through the final stages of distillation and dehydration and [...]

Plant Reliability: Updating Outdated Controls & Equipment in Aging Facilities

With the ongoing advancements in controls & automation solutions, most the ancillary equipment in aging facilities are beginning to show signs of age that could potentially contribute to plant shutdown. Too many of the existent controls and automation on ancillary equipment are band-aided together due to discontinued models and/or insufficient tech support knowledge of the existing operating platforms. In most [...]

Ethanol Final Filter Improves Plant’s Final Product Quality in Two Days

After commencing an enzyme trial, an upper Midwest ethanol plant discovered elevated sulfate levels as the dosed fermenters were cycled through the plant. Out of spec ethanol cannot be marketed, and plant operations needed to act quickly to fix the product to avoid costly product rejection fees or plant shutdown. The plant was familiar with U.S. Water's ethanol industry experience and the Ethanol Final Filter [...]
