In a petroleum refining industry, changes of crude and condensate characteristic are inevitable and design changes shall always be anticipated to accommodate these shifts. The changes of these crude and condensate have opened many possibilities for process flow scheme innovation in handling these crude and condensate in order to achieve an optimum design, reduction in energy consumption, flexibility in operation while ensuring construction is viable considering these cases are mostly revamping of a brownfield plant. This paper outlines a novel flow scheme to address diesel recovery from a heavy condensate or known as Black Condensate by incorporating a Vacuum Flasher Unit operating at a much lower vacuum pressure with multiple recycle streams introduced within the system to maintain balance vapor liquid traffic in the column to ensure good separation occurs. The novelties in the scheme assured good overall product recovery, with simplified flow scheme and better operational flexibility satisfying the revamp constraints of small plot space requirement.
