TLDR
In this paper, two reactive distillation processes using soybean oil as main feedstock along with the corresponding downstream separation units are simulated: the first process involves a homogeneous alkali catalyst; whereas the second involves a heterogeneous catalyst.About:

A review of the feedstocks, catalysts, and intensification techniques for sustainable biodiesel production
Moina Athar,Sadaf Zaidi +1 more
TL;DR: A review of the literature of the last twenty years was thoroughly studied and reviewed to examine the status of biodiesel in this article, where the authors discussed the availability of different biodiesel feedstocks and summarises how their characteristics affect biodiesel properties along with the criteria of their selection for sustainable and low-cost production.
Journal ArticleDOI
Technological, technical, economic, environmental, social, human health risk, toxicological and policy considerations of biodiesel production and use
Snežana Živković,Milan Veljković,Ivana B. Banković-Ilić,Ivan Krstić,Sandra S. Konstantinović,Slavica B. Ilić,Jelena M. Avramović,Olivera S. Stamenković,Vlada B. Veljković +8 more
TL;DR: In this paper, the authors overview the technological, technical, economic, environmental, social, toxicological and human health risk considerations of biodiesel production and use, and highlight the need to develop and apply corresponding sustainability criteria in a consistent way worldwide as soon as possible.

Magnetically recyclable acidic polymeric ionic liquids decorated with hydrophobic regulators as highly efficient and stable catalysts for biodiesel production
Heng Zhang,Heng Zhang,Hu Li,Hu Pan,Anping Wang,Sadra Souzanchi,Chunbao (Charles) Xu,Song Yang +7 more
TL;DR: In this article, a series of magnetically acidic poly(ionic liquid) catalysts with varying hydrophobicity and controllable acidity were used to improve biodiesel production process efficiency by acids.
Journal ArticleDOI
Investigation of energy-saving azeotropic dividing wall column to achieve cleaner production via heat exchanger network and heat pump technique
TL;DR: In this article, a green and sustainable heat integrated azeotropic dividing wall column (HI-ADWC) separation configuration is proposed by the combined use of heat exchange network and heat pump implementations.
Journal ArticleDOI
Investigation of an energy-saving double-thermally coupled extractive distillation for separating ternary system benzene/toluene/cyclohexane
TL;DR: In this article, a double-thermally coupled ternary extractive distillation (DTCTED) method was proposed to achieve energy saving and emissions reduction in benzene/toluene/cyclohexane (B/T/CH).

Analysis, Synthesis and Design of Chemical Processes
TL;DR: In this article, the authors present essential flow diagrams for understanding processes, including the structure of Chemical Process Flow Diagrams, and tools for evaluating system performance and performance curves for individual unit operations.
Journal ArticleDOI
Biodiesel production from waste cooking oil: 1. Process design and technological assessment
TL;DR: The acid-catalyzed process using waste cooking oil proved to be technically feasible with less complexity than the alkali-catalystzed process, thereby making it a competitive alternative to commercial biodiesel production by the alkaline-catalyszed process.
Journal ArticleDOI
Biodiesel production from waste cooking oil: 2. Economic assessment and sensitivity analysis.
TL;DR: Plant capacity and prices of feedstock oils and biodiesel were found to be the most significant factors affecting the economic viability of biodiesel manufacture.
Journal ArticleDOI
A process model to estimate biodiesel production costs.
TL;DR: A computer model to estimate the capital and operating costs of a moderately-sized industrial biodiesel production facility was developed and found the production cost of biodiesel was found to vary inversely and linearly with variations in the market value of glycerol, increasing by US dollar 0.0022/l (dollar 0.065/gal) for every US dollar0.01/lb change in oil cost.
Journal ArticleDOI
Assessment of four biodiesel production processes using HYSYS.Plant.
TL;DR: Four continuous biodiesel processes were designed and simulated in HYSYS and the heterogeneous acid catalyst process had the lowest total capital investment and manufacturing costs, and had the only positive after tax rate of return.
