“…As Bezzo et al (1999) mention the effect of electrolyte and salting out on thermodynamic modeling for the production of propylene oxide from propylene chlorohydrin and calcium hydroxide by using reactive distillation column. The modeling of the vapor-liquid equilibrium of the system becomes complicated by the presence of electrolytes and salting out effect.…”

The objective of this paper is to give a critical survey of the present status within the field of control of a reactive distillation column. Control of a reactive distillation column is a challenging task due to process nonlinearity and complex interactions between the vapor-liquid equilibrium and chemical reactions. There are different types of control methodologies, which have been studied in the reactive distillation, ranging from a simple proportional-integral (PI) controller to advanced model predictive controllers (MPC) such as dynamic matrix control (DMC), quadratic dynamic matrix control (QDMC), robust multivariable predictive control technology (RMPCT), generalized predictive control (GPC), and other advanced control techniques. With the goals of optimal performance, energy conservation and cost effectiveness of process operations in industries, the design of optimal controllers and controller performance assessment have received great attention in both industries and academia. The main objective of control is to maintain the product purity within the desired range.

“…The conventional epoxidation methods in the fine chemicals industries employs either stoichiometric peracids such as peracetic acid and m-chloroperbenzoic acid 10 or chlorohydrin 11 as oxidising reagents in liquid phase batch reactions. However, such processes are not environmentally benign as the former produces equivalent amount of acid waste, whilst the later yields chlorinated by-products and calcium chloride waste.…”

“…For the capacity over 30 000 ton product/year, it will be more economical if the preparation conducted via a continuous process. Some works have been done which relate mainly to continuous-flow processes for chemical synthesis, such as the esterification processes of methyl or ethyl-acetate (Venkataraman, Chan, & Boston, 1990), MTBE (Huang, Wang, & Ding, 2008), propylene oxide (Bezzo, Bertucco, Forlin, & Boarolo, 1999), bio-additive triacetin (Mufrodi, Rochmadi, Sutijan, & Budiman, 2014), biodiesel (Kusumaningtyas, Purwono, Rochmadi, & Budiman, 2014), etc. Reviews of the research, design, operation, scale-up and commercial application of this interesting area have been done by Harmsen (2007).…”

Pine trees in Indonesia are largely of the pine mercusii species which typically give turpentine that contains about 82% α-pinene, 12% carene and is balanced with numerous other components such as camphene, β-pinene and limonene. When treated with water in the presence of an acetic acid catalyst, α-pinene is hydrated to become a complex mixture of monoterpenes, alcohol and hydrocarbons, although α-terpineol predominates. This α-terpineol is a valuable compound which is widely used as a fragrant substance in the cosmetic industry as an anti fungal agent in the pharmaceutical industry, a disinfectant, an odorant in the cleaning industry and as a mineral flotation agent in the mining industry. A conventional configuration for this hydration process involves two steps, chemical reaction of α-pinene in a reactor followed by a separation step in a distillation column. In this experiment, we combined both chemical reactions and separation by distillation in a reactive distillation column to reduce the production and operating cost. Steady state condition, feed plate position, pressure and volumetric ratio of α-pinene and CAA solution were investigated to study the effect of using this method. A certain ratio of 87% weight of α-pinene and 5.3 M Choloroacetic Acid (CAA) solution as a catalyst were inputted to the reactive distillation column. The result shows that the highest purity of α-terpineol is 38.89 % weight.
