PRECAUTIONS FOR TANKS WITH INBUILT HEATING COILS

 PRECAUTIONS FOR TANKS WITH INBUILT HEATING COILS:

Design of facilities: 

Three interacting elements need to be taken into account when designing installations, particularly in terms of their compatibility with the operating conditions: - the nature of the products stored: flammable or non-flammable, likely to generate decomposition products that are themselves flammable or even explosive, requiring or not requiring temperature control; - the materials used for the storage tanks: flammable or non-flammable, and must be resistant to the products stored; - the heating elements: essential or non-essential, electric or using a thermal fluid (steam, hot water, heat transfer fluid, etc.), sized for a specific heating power. 

Reliable control equipment: - products are present in the tanks to prevent heating if tanks are empty (level and weighing sensors, etc.) - temperature of the thermal fluids used, the products contained in the tank, the atmosphere in the tank, etc. (appropriately positioned probes and sensors); - heating is controlled by the presence of product and by temperature control; - no contact between the heating elements and the tank’s walls; - monitoring of all of the installation’s operating and safety parameters. 

Regulated operating conditions: - preventive maintenance of facilities and equipment to prevent failures; - operating and intervention instructions (concerning the start-up of facilities in manual or automatic mode, shut-down of heating systems before intervention requiring tank emptying, after all interventions, etc.) - training of personnel in procedures and operating instructions; - monitoring and supervision of the installations during operations (the night prior, at night, early in the morning); - verification that all instrumentation and control channels are operating correctly, that the servocontrol and command logic is functioning correctly, and verification of automatic operation programmers.
