Creator:: Couturier, Patrick
Abstract:: A review of Single-Input Single-Output Internal Model Control (IMC) is presented, showing its relationships to the Dahlin algorithm, PID type controllers for simple models with and without deadtime and Smith predictor control. The effect of errors in the time constant and the gain of a first order model with deadtime...

Creator:: Sahle-Demessie, Endalkachew
Abstract:: The temperature-time-location relationships during steam conditioning and pressure treatment of timber poles have been studied and mathematical models that take into account both the thermal properties of the poles and the parameters of the treatment process have been developed. Although much work has been previously done in this area, the...

Abstract:: A column which contains a series of three fluidized beds for counter-current contacting of solid particles with a gas stream has been studied. Successful, independent control of solids holdup on each stage has been achieved by manipulating the field of a magnetic distributor-downcomer on each stage. Two methods to manipulate...

Abstract:: Two packages of subroutines were developed to perform material balances on chemical processes using the simultaneous modular approach and the equation-based approach. The performances of these packages were compared for five different processes under at least two conditions: one with no design specifications, and one with two or more design...

Creator:: Oufer, Lounes
Abstract:: A study of nucleate boiling of water, four alcohols and three ethanol-water mixtures was conducted in a vertical thermosiphon reboiler. The test section consisted of a 1/2- inch diameter electrically heated stainless-steel rod jacketed by a 15-inch long pyrex glass tube. Two different inside diameters of the glass tube corresponding...

Abstract:: Problems with aluminosilicate scales in pulp and paper recycle streams create an interest in the formation mechanism and the chemical equilibrium of aluminosilicates. Evaluating solubility data from a system containing Na⁺ CI⁻, and OH⁻ ions as well as aluminium and silicon compounds, allowed to elucidate the characteristics of the aluminosilicate...

Creator:: Kelly, Barry
Abstract:: Chemical equilibrium is a major factor in many natural and industrial systems. The ability to predict ionic equilibrium is extremely valuable in industry in solving problems without the costs involved in full scale experiments. An example of an application in the pulp and paper industry is the prediction of non-process...
