HCl (0.12 molar concentration is stored in a tank of 1000 lit) at 8 degree celcius.

 

i want to increase its temperature upto 45 degree c . and maintain it to the same temperature.

what will be the procedure. kindly share ur views please?

Hi,

 

What is the MOC of storage tank? Its better to keep the HCL solution tank in water bath provided with electric heater & temperature controller or teflon coated electric heater directly immersed in the HCL solution.

dear samayaraj. 

Thanks for ur reply.

MOC is polypropylene.

and its not feasible for us to put the tank in water bath.

 

and we are thinking for a teflon coated elctric heater immersed in HCl solution.

 

can you please tell me how to calculate the required heat to go upto the temp of 45 degree c in what time?

Its Q = mC_p(dT/dt)

 

Where Q is the heat supplied (W), m is the mass of solution (kg), C_p is specific heat cap of solution (J/kg⁰C), dT/dt is rate of rise of temperature (⁰C/sec)
