Process Analysis of Shea Butter Solvent Fractionation Using a Generic Systematic Approach

Abstract

The application of lipid feedstocks has expanded across different industries as a result of bio-based economies development, consumers and societal requirements. The need for new and better performing lipid-based processes and products has resulted in extensive research within lipid thermodynamic property modelling. In this work, property models for lipid pure compounds and

Oleochemical Processing Technology: From Process Engineering and Intensification Techniques to Property Models for the Exploitation of Residual Marine Oils

“…In this context, numerous proposals have been made to exploit oil/lipid-based feedstocks that could lead to waste utilization and valuable products [11][12][13]. Among these, waste from the fishing industry has attracted great interest as it is a source of minerals, proteins, and fats with high potential for use [14].…”

Iterative lumping approach for representing lipid feedstocks in fatty acid distillation simulation and optimization

“…Perederic 2 developed a systematic identification method for data analysis and phase equilibria modeling for lipid systems applied to different UNIFAC variants. Most recently, Perederic et al developed a generic systematic approach for process analysis, which they applied to optimize shea butter solvent fractionation 12 . Table 1 lists recent modeling and simulation studies for lipids‐based processes and the approach used for lumping and selecting lipid compounds.…”

“…The choice of pseudocomponents may be a source of error, as an FA methyl ester is used to represent triglycerides, which have significantly different physical properties. Finally, Perederic et al 12 use a detailed composition and relate their process simulation to an in‐house lipids database, containing thermophysical data and models needed for the simulation. However, using a detailed composition for simulation is not always possible due the lack of physical property data for lipid compounds available in commercial databases 18 .…”

“…Most recently, Perederic et al developed a generic systematic approach for process analysis, which they applied to optimize shea butter solvent fractionation. 12 Table 1 lists recent modeling and simulation studies for lipids-based processes and the approach used for lumping and selecting lipid compounds. Most frequently, all FAs were lumped and represented by one key compound for the whole range of carbon chain length and saturation.…”

Life cycle assessment of intensified processes towards circular economy: Omega-3 production from waste fish oil

“…These include food, bio-based chemicals, biopolymers, fuels and bioenergy. In this context, numerous attempts have been made to explore potential feedstock containing substantial oil/lipids which could also lead to economic processing of many products (Sharma et al, 2014;Perederic et al, 2020). For example, Jayathilakan (2012) reviewed the waste management and disposal in meat, poultry and fish processing industries in India.…”
