Equilibirum Reactor energy flow


I am Neehar. I am working on equilibrium reactor by considering it isothermal. I see that the energy flow is showing a negative value and would like to know what it means. For example, if -0.25 KW is shown, does it mean that much amount of energy is lost from the main energy source to reactor? Whereas, a heater energy flow is shown in positive. Kindly anyone let me know about it.

Yours sincerely,

If the amount of energy associated with the equilibrium reactor is negative, say -0.25 kW, it means that 0.25 kW amount of energy has to be removed to get the product at the desired temperature. In other words, the process is an exothermic one.

In the case of the heater, the heat flow amount is shown as positive is because that much amount of energy is required to raise the temperature from feed temperature to the product temperature.

Thanks Ankit Kumar.

So, that means, the reactor is having a circulating fluid which takes that amount of energy to maintain the product temp (reactor outlet temp)?

 Thank you for posting that it could be just the thing to give inspiration to someone who needs it! Keep up the great work!
