39. GLOBAL TRANSPORTATION SCENARIO Worldwide other modes of Transportation are also being used like thro’ Barges on Water for more than 6000 kms distance in Columbia, Chile & for very short distances, Pipelines 1200 Road (100%) 51 India 1000 200 Rail (67%) Road (33%) 6 Europe 600 300 Rail (30%) Road (70%) 10 Japan 4000 (Brazil) 1500 (Chile) Road Rail (75%) 66 South America 1000 Rail (90%) Road (6%) 35 North America Max. Distance Covered (Kms) Mode of Transport Quantity of Cl2 Transported (% of Production) Country

Withdrawal rate of Chlorine ( Room Temp. – Threshold temp.) * withdrawal factor withdrawal factor for Tonner = 8/ Cylinder= 1 Threshold temp. is the temp. where minimum required gas pressure is reached Temp.

88. EMERGENCY HANDLING FROM POSSIBLE LEAKAGE POINTS OF TONNER Close the valve - Provide O/L brass seal nut. - Provide additional valve with Clamp. - Use emergency kit Sr. No. Particular Problem Action 1 Gland leakage - Gland nut loose Tighten the gland nut with suitable spanner 2 Chlorine valve passing Pitting on the spindle seat - Pitting on valve seat - 3 Chlorine valve damage - Valve broken - Use emergency kit to control leakage 4 Leakage from tonner surface - Pin hole on the surface - Use emergency kit to control leakage 5 Leakage from blind plug - Thread damaged - Use emergency kit to control leakage 6 Leakage from O/L of the Cl2 Valve - Thread damaged - Pin hole in the outlet nozzle - Gasket not properly fitted - Dosing line leakage - Close valve - Rotate Tonner to 180 deg., Use 2 nd valve - Replace gasket - Replace the dosing line
