“…Methyl ester content, obtained from methanolysis of castor oil, was determined using a GC-7890B (Agilent, Santa Clara, EUA) equipped with flame ionization detector analysis (GC-FID) and Stabilwax capillary column according to Menshhein et al [13,14] however with a split ratio of 1:50. The ester content (in mass percentage) was determined relative to the peak area of the internal standard (EN, 2003).…”

“…Bio-oil samples obtained by thermal cracking of ricinoleic acid, castor oil and methyl esters, were analyzed using the same GC-FID equipment with split ratio of 1:200 according to Menshhein et al [13,14]. The compounds were identified by comparison of their retention times with those of heptaldehyde, undecylenic acid and methyl undecenoate standards (Sigma Aldrich).…”

“…Recently, based on the work of Botton et al [8] and samples of bio-oil produced by thermal cracking of methyl ester in castor oil under isothermal condition (525 °C) and different residence times, Menshhein et al [13,14] evaluated a process for separation and purification of heptaldehyde and methyl undecenoate with distillation as downstream operation, with an absolute characterization of the products using gas chromatography (GC). As a result, it was possible to concentrate the products in fractions with heptaldehyde and methyl undecenoate in atmospheric distillation.…”

This work evaluated the process for heptaldehyde, undecylenic acid and methyl undecenoate production from castor oil, methyl ester of castor oil and ricinoleic acid. Experiments were performed in a continuous pilot-plant scale pyrolysis reactor. Those are very important green chemical products that might be obtained by the thermal cracking of castor oil. Transesterification of castor oil produces methyl ricinoleate and its thermal cracking generates methyl undecenoate and heptaldehyde. The pyrolysis temperatures tested were 530, 545, 560, and 575 ?C, with residence time from 17 to 32 s and mass flow at 400 g/h of the mixture of materials with 25% distilled water. It was observed that the temperature influence in relation to bio-oil generated and their differences for each material. The bio-oil was characterized by iodine index, acid number, mass, and the contents of its compounds were obtained by GC-FID chromatography. The best result for the undecylenic acid mass yield of the desired compounds occurred at 530?C, achieving 17.8 % from ricinoleic acid and 16.5% from castor oil. For the heptaldehyde the highest production was also obtained at 530 ?C, with a value of 20.7% from methyl ester and 15.2% from ricinoleic acid.

“…Bio-oil has a large variety of compositions as a function of the feedstock. It can be produced from biomass based on triglycerides like soybean [18], castor [4,23,24] and canola [25], as well as animal fats [26], lard, poultry fat [27] and fish oil [17], and the major products are alkanes, alkenes, ketones, aldehydes, aromatics and carboxylic acids.…”

Pyrolysis of triglycerides based on biomass was used at large scale for fuels supply during the world wars. For this study, the bio-oil produced from waste fish oil pyrolysis was fractioned in a distillation column to produce a light fraction cut in the range of gasoline. This biofuel was tested in a motorcycle engine to measure its performance in terms of torque and analysing its exhaust gas composition. The emissions were assessed by exploring the combustion of a fossil gasoline without additives and with blends of bio-gasoline, BG20 and BG30 fuels, meaning 20 and 30% of bio-gasoline in fossil gasoline, respectively. Results allowed the identification of the torque and emission gases combinations for each fuel type and the determination that as the percentage of bio-gasoline in the gasoline is increased, the concentration of CO2, CH4, C2H6, C3H8 decreased in direct relation to the engine rotation. The results show that bio-gasoline can be used as an additive of fossil gasoline with gains of performance in terms of torque and lower concentration of CO2 in the emissions. The torque increased from 3.5 to 3.7 N.m and from 4.0 to 5.0 N.m at fifth gear and at 2000 and 4000 rpm, respectively.

“…Due to the thermal cracking of high molecular weight components that are present in CT [29][30][31], the distillation process is accomplished under vacuum below 300 °C. The advantages of vacuum distillation processing are increasing relative volatilities at lower pressures and reducing the temperature requirement at lower pressures in the system [32,33].…”

Preventing of flooding phenomena on vacuum distillation trays column via controlling coking value factor

2020

The occurrence of flooding phenomena (FP) on the vacuum distillation trays column (VDTC) is investigated on a refinery in the middle region of Iran. Accumulation of coke sediment that is occasionally observed in refinery processing using coal tar (CT) feeding is the main reason of the FP on VDTC. This usually occurs at the down-comer areas and the seal pans of the column. Quinolone insoluble (QI) and toluene insoluble (TI) parameters, two routine methods used to measure coke containing sediments, are employed to determine probable critical areas of FP at the down-comers and the seal pans of CT feed in this study. Analyzing the obtained results of QI and TI tests demonstrated that FP at the column is directly related to the quality of CT feeding. For instance, when the QI of the inlet CT in battery 1 increases from 0.56%W in the first sample to 6.5%W in the 25th sample, the vacuum pressure at the top of the distillation column is reduced from − 230 mbar to − 420 mbar. To prevent sediment accumulation of coke and the occurrence of FP, the CT feeds are centrifuged to reduce coke sedimentation at the down-comer areas and the seal pans of VDTC. Moreover, the seal pan trays are replaced by normal ones and all moveable valves with 25 mm diameter on trays 15 and higher in the column, where coke sediment accumulation is observed the most, are modified by installing wider fixed valve (40 mm diameter) trays.
