Therefore, coke deposition by pyrolytic mechanism becomes less significant in the downstream equipment due to the decreasing temperatures, but at the TLE inlet (cone and tubesheet) such coke formation must be considered. One of the additional factors, worth considering, is the nonideal flow distribution in the process stream (e.g. TLE inlet cone).
