Abstract:
Thermochemical conversion of low energy pre-treated municipal solid waste in recent times has become an attractive growing technology. The quality of municipal solid wastes (MSW) needs an improved analysis to enhance her choice for energy exploitation and environmental assessment of fly and bottom ashes associated with the thermochemical conversion. The MSW were collected from Solid Waste Disposal facilities (SWDF) in Cape Town to investigate heavy metals distributions in the municipal solid waste obtained from SWDF. The municipal solid wastes were pre-treated to improve the quality of MSW. The 7700 Series quadruple ICP-MS solution method was used to determined concentrations and distributions of some heavy metals from SWDF in Cape Town. This study assesses and quantifies distributions of heavy metal in solid municipal solid waste in city of Cape Town. The results show significant levels of Fe, Al, Pb, Zn and Hg. The accumulation of high concentrations of heavy metals in bottom ash residue from thermochemical conversion could be a good remedy for heavy metals control. The transfer of these metals to bottom ash residue during and after thermochemical conversion was determined analytically.

Abstract:
RHT-ETBE and RHT-TAEE are the smart configuration technologies to enhance the conversion to over 97 to 90 percent respectively by having multiple side-draws from the columns and one can much better quality also than competitive technologies. The major advantage in these processes is that it allows wet ethanol to be use in the process and still meeting TBA and TAA specifications in the product. The process makes these tertiary alcohols, but is separated from the Ethers and is decomposed to iso-olefin and is recycled with the feed. The additional equipment for higher alcohols been made is paid off in few months compared to the cost of dry ethanol. Essentially process is rejecting the water from wet ethanol and makes high quality ethers at low Capex and Opex to the competitive processes. RHT- Biodiesel process is optimized to produce biodiesel from palm oil, Rape seed oil, vegetable and animal product that are all fatty acids with even number of carbon atom typically 12 to 22 atoms. The lack of sulphur in the biodiesel means it meets all international specification once the boiling range is right and these are comparable to hydrocarbon diesel. The triglycerides are reacted with methanol/ ethanol or higher alcohol which all produces biodiesel in the acceptable boiling range. Methanol is most commonly used for the biodiesel production as being the cheapest alcohol, hence provides better economics. Biodiesel is produced by reacting triglycerides with methanol in the presence of highly alkaline heterogeneous catalyst at moderate pressure and temperature into fatty acid methyl esters. After the transesterification reaction the product, methyl esters of those oils /fats as product and glycerine is produced as a by-product. Glycerine is separated from the methyl esters of vegetable oils that are the biodiesel by phase separation by gravity settling due to density differences. The methyl esters and glycerine are purified to meet the product specifications. The unit has capability of having (patented) flexibility to enhance the on stream factor by additional parallel transesterification reactor. If the feed has high content of free fatty acid than esterification is performed and the technology is able to provide that reaction also to meet high overall conversions and selectivity at low Capex and Opex without producing any liquid waste.

Title: Systematic and knowledge-based invention in science and industry-2; TRIZ, IDM-TRIZ, and STEPS software
Time : 10:50-11:20
Biography:
Ali Taheri completed his PhD in Industrial Engineering at the University of Strasbourg in 2015. He holds Master’s degrees in Systems Engineering and Integrated Design Process – from Grenoble Institute of Technology – and an advanced studies’ Master’s in Innovative Design including Inventive Problem-Solving from the INSA of Strasbourg. His research focuses on the inventive efficiency of R&D teams and on technology road-mapping. His published work deals with the metrics of inventive performance, helping R&D managers to monitor and enhance innovation projects. After nearly a decade of experience in academic and executive programs aimed at improving the chain of production from idea generation to manufacturing, since November 2015, he settled in the United States and founded Exaura Company in order to assist design engineers and SMEs in reducing the risks of new product development.
Abstract:
The theory of inventive problem-solving – Russian translation of the acronym TRIZ – is known as one of the approaches that more likely steer R&D teams toward achieving creative results. In this occasion, I will provide a snapshot of this theory, and then the research results of INSA-Strasbourg that led to the development of a methodology, namely "Inventive Design Method based on TRIZ" (IDM-TRIZ). This also includes the introduction of STEPS software that has been provided with a methodological support to operate IDM-TRIZ.

Abstract:
Carboxylic acids are commonly generated in biorefinery operations such as fermentation or aqueous extraction of hemicellulose feedstocks. In most cases, organic acids are generated as dilute components in aqueous streams. If they can be recovered from solution inexpensively, they may find value as pure chemical products or as starting materials for a wide variety of organic products, including biofuels. Liquid-liquid extraction is a separation method applied to recover mixed carboxylic acids from a fermented wood extract. These acids included: Acetic, propionic, butyric, valeric, caproic and heptanoic acids. An organic solution, such as trialkylphosphine oxide (Cyanex 923, a mixture of four trialkylphosphine oxides), was mixed with fermented wood extract to extract these acids. Although the extraction was highly effective, however it was shown that distillation was not able to recover these acids from the extraction solvent. In this study, after liquid-liquid extraction of the acids from the aqueous phase, the mixed acids are recovered from the organic phase by a back extraction with sodium hydroxide. The mixture is agitated and centrifuged to separate the organic and aqueous phases. Results present the extraction and recovery efficiencies of this method of recovering organic acids.
