» You are asking yourself why:

• When you open a valve there is no increased flow.
• The pump on your unit frequently blows its seal.
• An increase in distillation tower top reflux makes fractionation worse.
• A heat exchanger on your unit always fouls before scheduled cleaning.
• The fired heater run length on your unit is suddenly so short.
• There is no more heat to the distillation tower when steam flow to the reboiler is increased.
• The vacuum is so low on your vacuum tower.
• There is no increased cooling after installing that new condenser or overhead cooler.
• The water cooler fouls even faster after changing the number of passes.
• The computer simulation does not predict current operation.
• Control loop does not work.
• You have been asked to approve a drawing for new or revamped equipment which you do not understand and have no way to know if the equipment would work as shown.
