“…The process was designed and simulated in HYSYS ® reaching high conversions of biodiesel (99%). Similar results were obtained by Souza et al (2020) studying a biodiesel process using the Aspen Plus ® simulator using palm oil as raw material and NaOH as a catalyst in a 6:1 molar ratio of ethanol/oil and reaction temperatures between 60 and 80 °C, obtaining biodiesel conversions up to 96%.…”

In There are few simulation studies in the literature focusing on the production of biodiesel from vegetable oil deodorization distillate (VODD), a waste originating from the vegetable oil processing stage, using hydrotalcite-hydroxyapatite as a heterogeneous catalyst. In this study, the simulation process was performed using open interface software DWSIM® Version 6.3. The motivation relied on the positive performance of the catalyst during the experimental studies. So, in the simulator design, the lipid raw material, ethanol, and the catalyst were fed together in a CSTR-01 conversion reactor. The thermodynamic fluid package used for this process was the Non-Random Two-Liquid (NRTL) activity coefficient model. The process flowchart consisted of the reaction step (oil transesterification), and separation steps of the ethyl esters produced, excess ethanol and purification of biodiesel. As a result, different scenarios were simulated, using commercial soybean oil as a comparative form, different types of catalysts and different molar ratios of alcohol and VODD. Among the main differences between the simulated cases, it was demonstrated that the excess of alcohol (1:45) caused greater quantity of VODD consumption, and consequently the greater formation of ethyl esters (biodiesel), resulting higher conversions (> 95%). In addition, the results obtained confirmed the adequacy of VODD as a potential raw material to produce biodiesel, as it is relatively cheaper than edible oils and contributes to the use of waste. Thus, confirming that the chemical catalyst was able to form the main esters of fatty acids even using a residual raw material.

“…Another work by Kamarden et al 19 reported a simulation model based on Aspen Plus for integrated palm oil processes involving milling refining and oleochemical production. Apart from these limited works on the modelling of palm oil refining processes, more recent modelling works are mostly reported for the utilisation of palm biomass, for example, for the production of biofuel 20,21 and biohydrogen 22,23 . It can be seen that there is a clear lack of literature on the modelling of physical refining processes, which is a key step for edible oil production.…”

Deodorisation is the key process to produce high‐quality refined, bleached and deodorised palm oil (RBDPO) in a palm oil refinery. In this work, an integrated simulation–optimisation approach was adopted for the analysis of a deodorisation process in an operating palm oil refinery. The process includes a deodoriser unit that removes free fatty acids (FFA) from bleached palm oil (BPO), and a vacuum scrubber utilising palm fatty acid distillate (PFAD) to reduce the FFA content entering the vacuum system. Being a proprietary technology, deodoriser is not found in the standard models of commercial simulation software. Approximation was made in simulation, with results compared to plant data. Detailed analyses showed that the reduction of FFA content relies on deodorisation temperature and pressure, stripping steam flowrate, as well as the temperature and flowrate of PFAD entering the vacuum scrubber. An optimisation model was solved to maximise profit from the deodorisation. Results showed that the FFA content entering the vacuum system is reduced significantly by 49.7%, leading to higher recovery of FFA in PFAD and lower loss into the condenser section. Applying the optimum values to the refinery has resulted in FFA levels greater than 91.2% in PFAD and RBDPO yield improvement of 0.5%.
