Temperature-responsive hyperbranched amine-based polymers for Solid-Liquid Separation.
Langmuir, 2014Co-Authors: Yinan Wang, Yohei Kotsuchibashi, Ravin NarainAbstract:Temperature-responsive hyperbranched polymers containing primary amines as pendent groups have been synthesized for solid–liquid Separation of kaolinite clay suspension. The effects of temperature, polymer charge density, and polymer architecture on particle flocculation have been investigated. Suspensions treated with the temperature-responsive amine-based hyperbranched polymers showed remarkable Separation of the fine particles at a low polymer dosage of 10 ppm and at testing temperatures of 40 °C. In comparison to other polymers studied (linear and hyperbranched homopolymers and copolymers), the temperature-responsive amine-based hyperbranched copolymers showed better particle flocculation at 40 °C, as evidenced by the formation of a thinner sediment bed without compromising the amount of clay particles being flocculated. This superior solid–liquid Separation performance can be explained by the hydrophobic interaction of PNIPAM segments on particle surfaces or the capture of additional free particles o...

Computer based selection of solid/liquid Separation equipment
2009Co-Authors: R J Wakeman, E S TarletonAbstract:Filtration and Separation technology contains numerous heuristics, evidenced by consulting industrial reference books such as Solid/Liquid Separation Equipment Scale-Up. A majority of industrial process engineers need to possess wide ranging knowledge covering many unit operations and rarely have the opportunity to gain in-depth specialist knowledge of filtration and Separation technology. Consequently the large number of heuristics that have evolved in the technology are confusing. Solid/liquid Separation technology, whether it be in the areas of selection or design, is best dealt with by software designed to run interactively, so that the engineer can input data and receive a result rapidly. An expert system such as pC-SELECT can be used to ensure the correctness of input data as far as this is possible, and it can utilise interactive graphics facilities to show effects of changes in variables or to allow the engineer access to calculations to make value judgements. To be most effective the software must be a well-chosen mix of algorithms, expert system, and input information by the engineer. There exist a number of charts which serve as a guide to the approach to equipment selection, the better ones of which consider a variety of possible eventualities and indicate where decisions must be made. These charts generally have been devised by experts to be fairly comprehensive and are of value to the solid/liquid Separation expert. They also illustrate the near impossibility of combining comprehensiveness with useability when so much interacting information is presented in written form. Purchas introduced a general guide for the non-specialist, which is a valuable aid to one confronted with this confusing and complex area. This guide is adopted, suitably extended and adapted, for use in the software pC-SELECT which incorporates features of the type discussed in this paper.

Expert system for solid/liquid Separation equipment selection
2009Co-Authors: E S Tarleton, R J WakemanAbstract:Commercially available expert systems on their own are inadequate for solid/liquid Separation equipment design and selection. Software which utilises a well-chosen mix of algorithm, graphics, expert system, and interactive input from the engineer is more effective. An example of the application of the combined approach to equipment selection is given to demonstrate that efficient software can save time and enable decisions to be made rapidly. Equipment selection using the pC-SELECT software is shown.

New computer software for the selection of solid/liquid Separation equipment
2009Co-Authors: E S Tarleton, R J WakemanAbstract:The paper details new Windows® based computer software for the selection of solid/liquid Separation equipment. The software interprets information obtained from databases through an inference engine to generate numerically ranked equipment selection whilst maintaining a balance between ease of use, level of knowledge conveyed and comprehensibility. The software facilitates the integration of additional information for special process requirements, solid and liquid phase properties as well as access to text and pictorial descriptions of equipment types. Hyperlinks with databases provide access to equipment manufacturer details. Facility for other user definable hyperlinks is also provided to access information sources on the world wide web via the internet. It is shown how the software for equipment selection will ultimately be integrated with software for equipment scale-up and simulation.

Selection of equipment for solid/liquid Separation processes
Filtration & Separation, 1995Co-Authors: R J WakemanAbstract:Abstract A formalised procedure for the selection of solid/liquid Separation equipment is presented, based on existing software and published information. The step-by-step approach in the procedure eliminates unsuitable equipment, and provides a shortlist of hardware potentially suitable for the application. Important aspects of each step are tabulated, to provide an aid to the design engineer. The approach is designed to be capable of extension to form a computer-based expert system.
