The Indian River BioEnergy Center, a cellulosic ethanol production center near Vero Beach, Florida, has completed a major turnaround, including technology upgrades, and the facility is now being brought back online, Ineos Bio said in a press release.
&ldquo;We will soon finish installation of equipment that will be used to remove impurities from one of our process streams that have been negatively impacting operations,&rdquo; said Nigel Falcon, site director. &ldquo;This equipment will be commissioned and brought online over the remainder of the year.&rdquo;
A nine-page Florida Department of Environmental Protection, Division of Air Resource Management document published online reveals that the company had produced little to no ethanol due to production of low levels of hydrogen cyanide (HCN), which is toxic to the bio-organisms in the fermentation process. The company received preliminary approval from the state environmental protection department to install wet scrubbers to remove HCN to levels of less than 5 ppm at full gasification rates.
An Ineos Bio spokesperson said the document was not supposed to be released by the state due to business confidentially reasons. Requests to the state environmental protection department for additional information were not returned.
The facility, which can produce of 8 MMgy of cellulosic ethanol and produce 6 megawatts of renewable power at full capacity, <a href="http://www.ethanolproducer.com/articles/10343/a-waste-filled-proposition" target="_blank">came online last fall</a>.&nbsp;It&rsquo;s a joint venture commercial demonstration project between Ineos Bio and New Planet Energy. The facility will produce cellulosic ethanol from multiple waste streams, primarily yard waste, but also municipal solid waste, biomass, vegetative matter, land clearing debris and untreated wood collected by the waste disposal district.
The company has now spent a year investigating the issue and testing options for improving operations, Falcon said in the press release. It is now in the final stages of implementing its plan to upgrade the facility over the next six months. &ldquo;We fully expected to encounter new challenges as we scaled up this exciting new technology,&rdquo; he said. &ldquo;We&rsquo;ve taken the time to develop solutions that will enable reliable production of high quality bioethanol. The efforts moving forward will continue to focus on safe operations, optimizing the technology, and de-bottlenecking the plant to achieve full production capacity.&rdquo;
