Energy Research, Dec. 1994.18, (9), 777-782. Simultaneous measurements of thermal conductivity and thermal diffusivity of composite red-sand bricks, glycerine and mercury have been made at room temperature by the recently developed transient plane source (TPS) technique. The paper describes, in brief, the theory and the experimental conditions for the simultaneous measurements of thermal conductivity and thermal diffusivity of insulators, fluids and metals. The source of heat is a hot disc made out of bifilar spirals. ‘Ihe disc also serves as a sensor of temperature increase in the sample.

On-lure sensors, which give instantaneous analytical measurements, can lead to significant energy savings. Recent developments in many mctalluraical and chemical DfDCCSWS have increased the rates of reactton sianifi&tly so that frqtiently conventional anal sis is the slowest step.-In a substantial number of cases, time, fuel, porlution and the use of human resources can be greatly reduced if on-line sensors are used. With the s is a possibility availability of computers, direct control of the pm whereas conventional analvsis invariablv aives a result which is rctrosoccr reviews the’possibility oi &ing on-line sensors, based ; n as a means of control and energy saving in the metalp” ur&al industry.

In this paper, the fuzzy set theory was incorPoratcd into SDGs to overcome these obstacles. The results of a trial diagnosis shows that the proposed approach improves the accuracy of rcsolutlon and provides more valuable information on the arrangement of fault origin candidates by the seriousness of the abnormality of the variables. %I021 51 Rapld datarmlnatlon of tha total contant of humlc acid In coal aamplaa by using mlcrowava-haatlng method Gao, Q. ef al., Fenxi Ceshi Xuebao, 1994, 13, (2), 74-78.

The selective removal of sulphur compounds from acid gas streams containing H$, COS and CO, necessitates detailed knowledge of the kinetics of the reactions of COS and CO, with amines. The latter has been studied in great detail and it has been firmly established that the reaction order in ammes increases from first to second with increasing concentration. This and secondary amine solutions type of non-linear bchaviour with has been explained both in terms op”9”y* xwrtterron intermediate and single-step termolccuhu reaction mechanisms.

FTIR sp&roscopy is an important method for the stud of the structure of carbonaceous materials, such as coal, coke, carbon brsck, active carbon, and pitch. Smoothinn and derivative calculations are used for the interon+ tation of spectra. R&&r are given for appl ing a least-squares procedure with pol nomials to obtain a mathematrca! model of the IR y Of coals, w g*rch is useful for smoothing, band resolution, peak fin mg, and data compression.
