Book excerpt: Oils are generally chemicals that are used in various industries, especially in paints industries. There are three classification of oils, drying oils, non-drying oils, and semi-drying oils. They are classified by their ability to absorb iodine per 100 grams of oil-also known as the iodine value (IV). Drying oils are majorly used as additives to chemical paints and varnishes in order to aid in the drying processes of these chemicals when applied onto the surface as finishes. Drying oil can be produced from various sources such as acetylated castor oil. The feed was modelled as palmitic acid- or acetylated castor oil- for its availability and the ease of processing it into drying oil. The drying oil was modelled as 1 tetradecene. The aim of the project is to design a chemical plant that can produce 50, 000 tonnes of drying oil per year from Acetylated [sic] Castor [sic] Oil [sic] -also known as Palmitic [sic] Acid [sic]. For the production of drying oil, there are two main reactions. First decomposition of Palmitic [sic] Acid [sic] into Acetic [sic] Acid [sic] and 1-tetradecene. Second reaction produces gum (1-octacosene) as an[sic] by product. Moreover, recent developed process introduced the production of the drying oil (1-tetradecene) through the thermal cracking of acetylated castor oil. A lot of research has been done with different technology where it was decided in this project, the most beneficial reactor would be the continuous stirred tank reactor (CSTR) , where it has high conversion rate per reactor volume, best for large capacity processes and inexpensive to design and operate comparing with PFR. After the thermal cracking of acetylated castor produced drying oil and acetic acid and gum in CSTR. The mixture leaving the reactor and then enters a filtration where the gum is the solid product to be removed. The filtered liquid that contains acetic acid drying oil and unreacted ACO enters a distillation column where ACO is separated from the mixture of DO and AA, then it is recycled back into the feed. The DO and AA mixture enters another distillation column where they are both separated and stored. The product stored is of high purity, 99%, The [sic] reactor has 80% conversion [10], The [sic] conversion of acetylated castor oil to acetic acid is 0.245 at 330°C [34]. After designing the Process Flow Diagram (PFD) based on the literature reviews, it was that calculated that 67338 tonnes of acetylated castor oil per year is required to produce 50, 000 tonnes of drying oil per year.
