A novel approach to FAME biodiesel production by means of reactive distillation
A novel concept of reactive distillation is examined in this dissertation. The design and construction of a rig to test the novel set-up were executed. The design of the rig was based on residence times selected for the rig's three main sections; the pre-reactor, the column and the reboiler. The …

Feasibility Analysis of Estrification Systems with Entrainers
… feasible to retrieve pure products by a simple reactive distillation for IPA production system because CCR (Critical Composition Region) covers the entire desired binary edge for IPA system. On the other hand, even though CCR does not cover the entire desired binary edge of the EA system …

Modelling and optimisation of batch distillation involving esterification and hydrolysis reaction systems. Modelling and optimisation of conventional and unconventional batch distillation process: Application to esterification of methanol and ethanol using acetic acid and hydrolysis of methyl lactate system.
Batch distillation with chemical reaction when takes place in the same unit is referred to as batch reactive distillation process. The combination reduces the capital and operating costs considerably. Among many different types of batch reactive distillation column configurations, (a) conventional …

Biological conversion of organic municipal solid waste to lactic acid : a techno-economic performance assessment study for commercialization
… LA, the method of esterification-hydrolysis with reactive distillation was selected for this assessment. The process from organic waste to high-purity LA was designed and modeled using Aspen Plus, from which material and energy balances, equipment costs, and utility costs were derived. An economic …

Design and Implementation of a Distributed Lattice Boltzmann-based Fluid Flow Simulation Tool
… like porous media or structured packing used in distillation and reactive distillation columns. These simulations require large amounts of memory (around 10 gigabytes) and would require very long execution times (around 2 years) if executed on a single powerful desktop computer. The execution of …

Large-scale production of oxymethylene dimethyl ethers
… the challenging water management using a reactive distillation column. As the heart of the production process, a suitable catalyst is required to selectively form the target OME product mixture. Various catalysts have been investigated for OME synthesis focusing on selectivity and …

Optimisation of complex distillation colomn systems using rigorous models
Since distillation is still the most widely used separation technique used in the petrochemical industry, optimisation of these unit operations are important to minimise costs and maximise production. This thesis focuses on the development of a tool using rigorous non-equilibrium distillation …
