The improved stripping efficiency generated a more stable operation in the chiller system without no freezing occurring due to the higher methanol concentration in the circula - tion solution, even at much lower methanol make-up rates. The blowback practice was completely eliminated, thereby decreasing the risk of operator exposure, preventing poten - tial flaring occurrences, improving the mechanical reliability of the liquid distributors and equipment, and increasing the system availability by at least four days a year. Considering the criticality of the installation to the success of the revamp, the work on the first train was managed by Koch Specialty Plant Services (KSPS) via the One-Source Solution approach, which ensures the work done meets the highest standards, guaranteeing a successful outcome. The operator, satisfied with the results, decided to revamp all five Ifpexol trains in its Canadian operation with

the redesigned configuration. Each train was evaluated on its own merits, and modifications to the designs were gener - ated where required. Savings due to increased efficiency in the strippers are in the order of C$3 MM/yr for all the trains. Additional savings on the reli - ability and operational fronts that are not easily quantifiable were also achieved.
