Carbon Dioxide Remediation or Removal in Biogas

What is the difference between carbon dioxide remediation and removal in biogas? Both are processes that change the raw biogas to another useful form, but there is a distinction.  Carbon dioxide removal is a form of remediation, but it is a more sophisticated and costly step in the “cleanup” of biogas.  Normally, the reason to…

Biogas

Biogas is a gas mixture developed from naturally occurring processes in nature.  Basically, bacteria that exist in our world digest organic material, and the by-product of their digestion is biogas.  Biogas is a mixture mainly of methane and carbon dioxide, but invariably contains many other compounds.  Some of the more significant compounds are considered contaminates,…

Biogas Conversion to RNG

Given the ideal circumstances, landfills offer good biogas conversion to RNG possibilities. Landfills produce a very large volume of biogas that can be converted to Renewable Natural Gas.  Landfills are typically very large, and when they have been designed to efficiently retrieve the generated biogas from the landfill, it is usually a very large volume,…

Emerging Feedstocks – Genetically Modified Trees

Genetically modified trees have been extensively academically explored as ideal feedstocks for pulp/paper and cellulosic ethanol. Novel trees include modifications that increase cellulose content, reduce lignin content, and even change lignin monolignol ratios. However, companies considering investing in these engineered managed forests need to examine technoeconomic feasibility prior to adoption. Specific attention to regulations, site…

Ethanol Proteins – Advanced Process Monitoring

Ethanol plants achieve the best quality ethanol proteins through advanced process monitoring and control.   That means starting with consistent control of corn grinding, cook and liquefaction and fermentation so that each fermentation batch is very consistent in terms of starch converted to ethanol.  Most ethanol plants were designed with simple DCS process control and simple…

Ethanol Protein – Importance of Co-Product Quality

Why is the importance of ethanol protein co-product quality? At least eight ethanol plants have recently installed new process technology that separates higher value corn fermentation protein from whole stillage. This ethanol protein is a combination of corn protein and yeast protein from the ethanol fermentation process. This protein product is destined for growing animal…

Hydrogen Applications

Hydrogen applications and uses are many and varied. As countries and companies move to reduce greenhouse gas emissions and transition to clean energy, hydrogen is increasingly the solution of choice. Green hydrogen from renewable sources holds the fantastic potential to reduce the carbon intensity of fuels, power production, transportation, chemicals, and other economically important applications.…

Hydrogen Experts

Among other things, hydrogen experts can assist with hydrogen fuel cells that produce electricity by combining hydrogen and oxygen atoms. The hydrogen reacts with oxygen across an electrochemical cell similar to that of a battery to produce electricity, water, and small amounts of heat.  However, instead of storing and releasing the electricity as a battery…
