Chemical Chemical REI provides research and consulting services to the chemical process industry. Computer simulations are used to analyze chemical process heaters.
Results lead to enhanced product yield and improved thermal efficiency.
Convective and radiative heat transfer to individual process tubes was computed as a function of tube length and position within the heater. Parametric simulations were used to study the effects of fuel changes and excess air variations on heat transfer and gas exit temperature. Convective and radiative heat transfer to individual process tubes was computed as a function of tube length and position within the heater. Parametric studies were used to evaluate the effects of load balancing and fuel heating value changes for the 50 burners along the floor of the heater. Ethylene Heater Coil exit temperatures were computed for an ethylene heater as a function of different firing conditions.
