Badania Emisji Chlorowodoru I Związków Fluoru Podczas Spalania Odpadów Niebezpiecznych, Marian Mazur, Robert Oleniacz, Marek Bogacki

Robert Oleniacz

The paper presents the results of measurements of the concentration of hydrogen chloride (HCl) and fluoride compounds (as HF) in raw and purified combustion gases discharged from the incineration of selected hazardous wastes. The study included two installations operating on an industrial scale: a multiple hearth furnace and a rotary kiln incinerator equipped with a single wet flue gas cleaning systems. In the multiple hearth furnace was being incinerated sludge from coke industry. In the rotary kiln were being incinerated coal (coke) tars, contaminated cleaning rags, sawdust, used gloves, outdated pharmaceuticals and medicines, hospital waste, waste paints, varnish and lubricant, …

Emisja Zanieczyszczeń Ze Spalania Odpadów Farmaceutycznych I Poszpitalnych W Piecu Obrotowym, Robert Oleniacz, Marian Mazur, Marek Bogacki

Robert Oleniacz

The work presents the problem of management and thermal treatment of medicines and hospital wastes and investigation results of incineration of these waste in the full-scale rotary kiln with wet gas cleaning equipment (alkaline scrubber). On the basis of measurements of air pollutant concentrations in combustion gases, maximum dose of these wastes in the feed to the kiln was specified in order to ensure a relatively low stack emissions using the hypothetical high-efficiency flue-gas treatment system.

English title: Pollutant emissions from incineration of pharmaceutical and hospital waste in a rotary kiln.

Recorders Play An Essential Role In Emissions Monitoring, Elizabeth C. Scheyder

PC-based recording devices perform many of the data acquisition tasks required by regulatory agencies today, but end users continue to rely on traditional paper-based recorders for extra comfort.

An Application Of Plausible Reasoning To Information Retrieval, Farhad Oroumchian, Robert N. Oddy

Farhad Oroumchian

This work explores the use of plausible inferences as a means of retrieving relevant documents. Collins and Michalski’s theory of plausible reasoning has been modified to accommodate information retrieval. Methods are proposed to represent document contents by logical terms and statements, and queries by incomplete logical statements. Extensions to plausible inferences are discussed. Two versions of the extended plausible reasoning system were implemented, one using dominance weights (described in the paper) and the other using tf. Idf (Term Frequency Inverse Document Frequency) weights. Experiments were conducted using the titles and abstracts of the CACM collection and it was found that …

The Performance Of Unifac And Related Group Contribution Models Part Ii. Prediction Of Henry's Law Constants, Yasar Demirel

YASAR DEMIREL

Henry's law constants for 24 different systems have been determined using UNIFAC and related group contribution models. The results obtained from original, modified and free-volume effect UNIFAC models are compared with experimental results. Empirical relationships for the temperature-dependency of Henry's constant for the chloroform(l) water(2) system are also determined.

Epitaxial Interactions Between Molecular Overlayers And Ordered Substrates, Andrew C. Hillier, Michael D. Ward

Andrew C. Hillier

A framework for evaluating the epitaxy of crystalline organic overlayers of generic symmetry on ordered substrates is described, which combines a computationally efficient analytical method for explicit determination of the type of epitaxy ~i.e., commensurism, coincidence, or incommensurism! and overlayer azimuthal orientation with an analysis of the elastic properties of the overlayer and the overlayer-substrate interface. The azimuthal orientations predicted by the analytical method agree with values predicted by semiempirical potential-energy calculations and observed experimentally for previously reported organic overlayers which are demonstrated here to be coincident. Calculations based on this analytical approach are much less computationally intensive than potential-energy …

The Performance Of Unifac And Related Group Contribution Modelspart I. Prediction Of Infinite Dilution Activity Coefficients, Yasar Demirel

YASAR DEMIREL

Infinite dilution activity coefficients have been calculated for 24 systems including highly non-ideal and nearly non-ideal using original, modified UNIFAC and UNIFAC-FV models. The calculations are compared with experimental results. The performance of the models in predictions and the significance of free volume effects on solvent activities in solutions containing small compounds are discussed.

Heat Transfer Through A Low-Pressure Gas Enclosure As A Thermal Insulator: Design Considerations, Yasar Demirel

YASAR DEMIREL

Heat transfer through gases at low pressures, rarefied media, plays a very significant role in the design of solar receivers and low-temperature cooling equipment. It is shown here that low-pressure and transition regimes of heat transfer prevail in such applications. State-of-the-art procedures for estimating these heat-transfer rates are presented together with an improved expression for the thermal accommodation coefficient for monatomic gases on engineering surfaces. The latter are characterized with values of thermal accommodation and reflection coefficients. Numerical calculations relevant to design engineers interested in these industrial applications are presented and the same are discussed for the dependencies of the …

PCs are making inroads in process control, but DCSs still rule in many applications. Here is why engineers go the DCS route, and what DCS makers are doing to keep it that way.
