Can Your Process Handle the Pressure? Eliminating Excessive Process Variability Phenol is a vital raw material in the production of high-impact resins that are used in the construction, transportation and other industries. Located along the Ohio River, Haverhill Chemicals produces a broad range of chemicals in technologically advanced operations. The plant includes operations of both phenol and bis-phenol A production units. When the performance and stability of critical production processes began to erode, engineering staff struggled with answers. Controllers responsible for maintaining consistent pressure within the plant’s distillation column fluctuated excessively. Variability in pressure made control more difficult, and it significantly reduced the unit’s performance. Staff found that
