HP Control: Controlling the mundane naphtha stabilizer, Part 2
Part 1 of this editorial (September issue) discussed a debutanizer control strategy (Fig. 1). Given that feed composition varies with ambient conditions, one could argue that unless you have advanced ..
HP Control: Controlling the mundane naphtha stabilizer, Part 1
Consider the distillation column in Fig. 1. It is called a "stabilizer" and removes LPG from naphtha. Every refinery has at least three of them, and often five or more, one each in every crude unit, r..
