Case Studies

Application-Specific Distributor Design Resolves Two Costly Column Problems

Field troubleshooting connected distributor selection, fouling, mechanical support and vapor backflow to severe packed-column operating failures.

Vacuum Tower Troubleshooting Restores Vacuum and Extends High-Performance Operation

Two refinery cases show how pressure profiling, operating-data reconciliation and fouling-resistant internals resolved vacuum loss and declining wash-section performance.

Demethanizer Revamp Improves Separation While Reducing Recycle Load

A distribution-focused internal retrofit restored fractionation performance and enabled operation above nameplate capacity.

Superfractionator Revamp Raises Purity While Reducing Reflux by 17%

GTI Solutions combined process modeling, high-performance tray technology and turnaround field execution to improve separation performance and operating flexibility in a large petrochemical superfractionator.
