      I am new to Refining.

      I intend to process Egina crude (API 27.3) in my CDU. I want to maximize diesel yield. To reach this goal, I intend to increase the temperature at the outlet of the fired heater to the maximum.

      What maximum temperature do you think I could go without coking?

      Thanks in advance

      The crude assay is here:
