Ethanol makers can gain particular advantages from coproduction.
As the ethanol industry evolves, more plants are seeking ways to increase their product slate and margin. One option is manufacture of isobutanol and its derivatives including octane, jet fuel blendstock and other drop-in hydrocarbons. Commercial production of bio-based isobutanol, alongside ethanol, has taken place since 2014 at Gevo’s Luverne, Minn., facility (Figure 1). The side-by-side operation there shares various streams between the two production trains to minimize capital and operating cost. The facility currently is being upgraded to enable production of 1.5 million gal/y of isobutanol and 15 million gal/y of ethanol. We have restarted isobutanol production with an expected output of 750,000 to 1 million gallons of isobutanol…

Solar Stills Make Small Scale Desalination Affordable
A new take on an old technology may make small-scale desalination systems affordable even for individual households.
While two thirds of the world’s population may face water shortages by 2025, according to an article from Science Magazine, water desalination plants that turn salt water into fresh drinking water have never been a feasible option for most communities due to their prohibitive cost. But that could soon change. Chinese researchers have improved on an old solar-powered technique known as a solar still that may put small-scale desalination systems back within reach, even for individual households.
Solar stills are large containers covered by clear plastic or glass that direct sunlight onto salt water. The water evaporates and then condenses on the plastic or glass where it is retrieved, while the salt is left behind. Because the method is…

The Connection Between CFM Demand & Energy Efficiency
Following this process will result in the lowest overall cost of ownership and will help prevent buyer’s remorse.
When considering an air compressor purchase, the primary concern should be receiving the right amount of compressed air for the lowest overall cost. Far too often, only the purchase price of the new machines is considered, and this is a small fraction of the total lifecycle cost. Energy costs are the real driver of a compressor’s total cost of ownership, and in many cases energy costs in the first year of use will total more than the purchase price of a new air compressor.
As a user, it is critically important to understand the performance of the air compressors that any engineering group or company will be providing and to choose the most energy-efficient solution to save on long-term energy costs. That’s why, when researching and…

Industry Harnesses Solar Energy
With limited availability of fossil fuels, solar energy will need to cover an increasing share of the industrial heat demand.
Industry consumes around one-third of the total primary energy demand. From that, around two-thirds of this industrial energy demand is used for process heating. Thus, sustainable solutions for industrial heat supply - like solar process heating - are needed for a transition toward manufacturing without carbon emissions.
At present, solar thermal energy isn’t typically applied in industry, for a variety of reasons. First, the legislative framework for renewable energies in most countries can be seen as somewhat biased toward power generation. Second, industry is often not aware of the opportunities of solar thermal technology and tends to invest its innovative capacities more on its products than its energy supply. Third, there is a lack…
Focusing on an implementation’s true consequences can lead to more cost-effective results
Undertaking an energy assessment can be a daunting task, but it doesn’t have to be if the energy expert can understand and follow an “impact analysis.” So, this column will cover this methodology and cite a few examples of how to undertake an impact analysis while doing energy assessments.
Published ASME standards for energy assessments provide a good starting point and offer guidelines for conducting these assessments. Nevertheless, our resources — budgets, human resources, and time — are always limited. Hence, there’s a strong need to undertake energy assessments from an impact-level perspective and increase the cost-effectiveness of these efforts. We are still talking about a systems approach; I’m not suggesting cutting…
