This research study investigates the modelling and simulation of biomass anaerobic dark fermentation in bio-hydrogen production a continuous plug flow reactor. A CFD multiphase full transient model long-term horizons was adopted to biohydrogen mode. Both discharge biomass, which prevents accumulation solid parts, recirculation liquid phase ensure constant access nutrient solution. The effect hy...

Leevijit, T., Wisutmethangoon, W., Prateepchaikul, G., Tongurai, C., Allen, M. Design and test of a continuous reactor for palm oil transesterification Songklanakarin J. Sci. Technol., 2006, 28(4) : 791-802 The continuous reactor for transesterification of refined palm oil with methanol was designed and tested. The reaction condition was focused at ambient pressure, temperature of 60oC, molar r...

The fermentation characteristics of six specific types of the organic fraction of municipal solid waste (OFMSW) were examined, with an emphasis on properties that are needed when designing plug-flow type anaerobic bioreactors. More specifically, the decomposition patterns of a vegetable (cabbage), fruits (banana and citrus peels), fresh leaf litter of bamboo and teak leaves, and paper (newsprin...

Gas-To-Liquid (GTL) processes have great potential as alternative to conventional oil and coal processing for the production of liquid fuels. In GTL-processes the partial oxidation of methane (POM) is combined with the Fischer-Tropsch reaction. An important part of the investment costs of a conventional GTL-plant is related to cryogenic air separation. These costs could be substantially reduced...

This is a discussion about sub-processes suitable for the rearing of insect larvae on dry and semi-dry feeds. Three closely related, key aspects are dealt with as part preliminary project design (PPD): type larval sub-process to be employed, reactor configuration operational approach used. A number types reactors discussed. Because they most commonly used in industry today, all ‘plug-flow’ (age...

This study demonstrated that a laboratory-scale recirculation closed-loop reactor can be an efficient technique for the determination of the Clean Air Delivery Rate (CADR) of PhotoCatalytic Oxidation (PCO) air purification devices. The recirculation closed-loop reactor was modeled by associating equations related to two ideal reactors: one is a perfectly mixed reservoir and the other is a plug ...

In this paper, control of a non-isothermal continuous stirred tank reactor in which two parallel autocatalytic reactions take place has been addressed. The reactor shows chaotic behavior for a certain set of reactor parameters. In order to control the product concentration, an optimal state feedback controller has been designed. Since concentrations of reactor species are ...

The ®alidity of an online state estimator for a semi-batch MMArMA solution copolymerization reactor was established using online densitometer and ®iscometer. Using the ( ) con®entional extended Kalman filter EKF as the state estimator, the experiment was conducted under both isothermal and nonisothermal conditions for application to the control of copolymer properties. Further analysis was made...
