Biodiesel production from vegetable oil: Process design, evaluation and optimization

Abstract

To investigate the effect of reactor performance/confi guration of biodiesel production on process parameters (mass & energy consumption, required facilities etc.), two diverse production processes (from vegetable oil) were implemented/designed using Aspen HYSYS V7.2. Two series reactors were taken into account where overall conversion was set to be 97.7% and 70% in fi rst and second processes respectively. Comparative analysis showed that an increase in conversion yield caused to consumption reduction of oil, methanol, cold energy and hot energy up to 9.1%, 22%, 67.16% and 60.28% respectively; further, a number of facilities (e.g. boiler, heat exchanger, distillation tower) were reduced. To reduce mass & energy consumption, mass/heat integration method was employed. Applying integration method showed that in the fi rst design, methanol, cold and hot energy were decreased by 49.81%, 17.46% and 36.17% respectively; while in the second design, oil, methanol, cold and hot energy were decreased by 9%, 60.57% 19.62% and 36.58% respectively.

Statistical Optimization of Biodiesel Production from Salmon Oil via Enzymatic Transesterification: Investigation of the Effects of Various Operational Parameters

“…A variety of vegetable oils extracted from corn, canola, palm, soybean, sunflower, rapeseed, coconut, and groundnut have been converted into biodiesel [14][15][16]. However, as most of these plant-derived oils are initially used for food, livestock feed, and oleochemical industries, biodiesel production results in increased consumption of these resources and increased crop demand [10].…”

An overview to process design, simulation and sustainability evaluation of biodiesel production

“…Mathematical programming has been widely applied to optimize biodiesel process synthesis problem, considering the economic trade-offs and interactions among subsystems. By far the most systematically considered synthesis problems in biodiesel production is the heat exchanger networks synthesis, separation sequences, and superstructure optimization for alternative technologies [ 41 , 86 , 87 ]. This methodology was implemented by Martin et al [ 42 ] to perform superstructure optimization of biodiesel manufacturing from microalgae and waste vegetable oil.…”

Refining Cannabidiol Using Wiped-Film Molecular Distillation: Experimentation, Process Modeling, and Prediction

“…Nevertheless, the extraction, separation, and purification technologies have not been able to keep pace with the rapidly growing and ever eager market. , For example, Rosenthal (2014) reported that only 40–70% of potential CBD is successfully obtained as a product, and the rest is lost during different steps of its refinement . The reasons behind the poor progress in the field are twofold: first, the limits imposed by legal impediments, and second, the lack of thermodynamic data as a critical barrier against modeling studies and equipment design and development. , Among different separation technologies, vacuum evaporation and distillation offer several benefits, making it the proper choice for processing thermolabile blends. It takes advantage of vapor pressure and enables the boiling of different constituents at decreased temperatures.…”
