10 Shell Thermia B Best performer in most demanding conditions Fluid Flow & Heat Transfer Coefficients On Heat Transfer effect of Fluid velocity Surface texture is very important At slow speeds over smooth surface,flow is usually laminar.

11 Shell Thermia B Best performer in most demanding conditions Fluid Flow & Heat Transfer Coefficients At Higher speeds with rougher surfaces, condition of turbulent flow will arise. To achieve maximum rates of Heat Transfer it is important to encourage Turbulent flow irrespective of whether the fluid is absorbing or discharging the heat.

13 Shell Thermia B Best performer in most demanding conditions THERMIC FLUID SELECTION CRITERIA 1. Operating experience 2. Operating Hazards : Toxicity, explosiveness & flammability. 3. Handling problems 4. Availability and cost

14 Shell Thermia B Best performer in most demanding conditions THERMIC FLUID SELECTION CRITERIA 5. Bulk / Film temperatures. 6. Thermal properties : Specific heat, conductivity, Heat transfer coefficient 7. Degradation rate. 8. Pumping properties

15 Shell Thermia B Best performer in most demanding conditions Requirements from a thermic fluid 4 Low solidification temperature. 4 Good thermal stability. 4 Low viscosity over the whole temp. range (also in the start-up condition). 4 Good heat transfer properties. 4 High specific evaporation enthalpy (when used as vapours).

16 Shell Thermia B Best performer in most demanding conditions Requirements from a thermic fluid 4 Low corrosion tendency for the materials of the apparatus 4 Non toxic and non - smelly. 4 Low sensitivity to impurities (e.g.. oxygen). 4 Low fire risk. 4 Low risk to the environment on leakage. 4 Possibility of easy destruction (passing used material into the natural circulation circuit). 4 Economy of operation

17 Shell Thermia B Best performer in most demanding conditions Heat Transfer Fluid Requirements n Good Thermal Stability n High Heat Transfer Coefficients n Low Vapor Pressure at Operating Temperatures n Low Viscosity to ease the Propagation of Turbulent Flow n Non Corrosive to metals n Non toxic

18 Shell Thermia B Best performer in most demanding conditions Chemical Composition Mineral oils are mixture of hydrocarbons Alkanes: Have carbon atoms arranged in straight or branched chains. Cycloalkanes: Contain some rings of carbon atoms. Aromatics:Contains rings of carbon atoms but a lower proportion of hydrogen than cycloalkanes.

19 Shell Thermia B Best performer in most demanding conditions Chemical Composition In addition, mineral oils may also contain small quantities of hetero atom compounds (sometimes known as asphaltenes) - organic compounds which contain elements like oxygen, nitrogen and sulphur.

22 Shell Thermia B Best performer in most demanding conditions Viscosity Viscosity increases with oxidation. Viscosity decreases with thermal cracking. Viscosity affects turbulence of flow. Viscosity at operating temperature is more important.

23 Shell Thermia B Best performer in most demanding conditions Flash Point Lowering of flash point is indication of something wrong but not necessarily dangerous. Method of sampling is very important. Sustenance of flash point during operation is very important from safety view point.

24 Shell Thermia B Best performer in most demanding conditions Flash Point COC (IP36/ASTM D 92) or IP 35 PMCC (IP 34/ ASTM D 93) Difference between the two flash points will be typically 15 0 C Repeatability difference: +/- 7 0 C Reproducibility difference:+/ C

25 Shell Thermia B Best performer in most demanding conditions Oxidation Stability Effect of Oxygen (or Air) on oil properties Various component of oil vary in oxidation resistance. Modern refining removes components with low oxidation resistance Higher the temperature higher will be rate of oxidation Copper & its alloys are catalysts for oxidation

26 Shell Thermia B Best performer in most demanding conditions Oxidation Stability Oxygen attacks hydrocarbons to form unstable peroxide derivatives. Some unstable peroxides further react to form acidic products which are oil soluble. Some form non soluble gum and sludge. Acidity and insoluble matter is measure of oxidation of oil.

27 Shell Thermia B Best performer in most demanding conditions Oxidation Stability Severe oxidation results in viscosity increase Oxidation in Heat transfer system takes place mainly in DE tank Pump may suck air causing oxidation Recharging of leaked fluid is also a source of oxidation

28 Shell Thermia B Best performer in most demanding conditions Thermal Stability Mineral oil is complex mixture of hydrocarbons varying in structure and molecular weight each with its own characteristic breakdown temperatures. Cracking is rupture of a carbon-carbon or carbon-hydrogen bond. Cracking reduces viscosity. Cracking reduces flash point.

29 Shell Thermia B Best performer in most demanding conditions Thermal Stability Lower weight molecular join to make heavy molecules which appear as deposits Deposits lower heat transfer efficiency

30 Shell Thermia B Best performer in most demanding conditions Other Properties Vapour Pressure: It is function of volatility Pour Point:Important for initial startup Density : For designing thermic fluid system Specific Heat Corrosiveness Fire Point

31 Shell Thermia B Best performer in most demanding conditions Specific Heat varies from 0.45 at 30 o C to 0.70 at 300 o C. Unit : Kcal/Kg FLASH POINT of fresh oil = 200 to 235 o C FIRE POINT = Flash Point + 30 o C Specific Heat & Fire Point
