Supercritical carbon dioxide (SCCO2) fractionation of d-limonene and canola oil mixture as a model of valuable components (i.e. essential oil and seed oil, respectively) from citrus processing residues was carried out in continuous countercurrent column. The effect of temperature and pressure on the recovery of d-limonene from top of the extraction column was investigated. Temperature gradient along the column was also applied to achieve effective separation. At isobaric condition (10 MPa), the highest enrichment of d-limonene in the extract could be obtained at 60oC. However, the highest recovery of the extract was found at 30oC. Evaluation of the separation
performance of this proposed process was carried out by calculation of mass transfer correlation coefficient, theoretical number of separation stages and solubility of the components in SCCO2.
The Biosolids conference attracts the most authoritative global experts in the area of biosolids and organic resource handling, treatment and recycling. The programme covers both the latest innovations and updates of existing technologies. Presentations from respected industry experts and newcomers follow the development of technologies and legislation from inception to full-scale installations.
The conference regularly gathers over 200 delegates from all over Europe, many of them return every year both for the technical presentations and fantastic networking opportunities.
Regular conference themes include:
• Thickening and Dewatering
• Modelling Sludge Handling and Utilisation
• Commissioning and Operating Experiences with Thermal Hydrolysis
• Tackling Potential Odour Problems
• Operating Experiences and Potential Problems in Digester Operation
• Ensuring Optimum Energy Recovery from Biogas
• Liquor Treatment and P Removal
• Alternative Products from Sludge
• Enhancing the Value of Biosolids and Digestate
• Pathogens and Pollutants In Digestate
• Sharing Experiences
