We injected between 2 to 3% ( weight)  of the total flow goint to the heater  and the temperature is between 805 and 800 degrees ºF ; with this  we have eliminated the formation of coke in our units in overhead  lines going to the frac. , except in the vertical line just leaving the coke drum , where it always has been formed coke between the flange of the drum and the flange of the pipe
