In 2018, Kelvion completed an airside revamp of an Overhead Condenser (OVHD) in a Gas Processing Plant in Middle East. The air-cooler has 10 induced fans, and the process is mainly composed of Methane (85%) and Propane (5%).
The OVHD Condenser was facing cooling capacity issues due to high ambient temperatures (52.0°C in summer) that were far above the original design (46.0°C). The process flow rate was limited to 367.2 t/h @ 49.5°C to ensure the outlet process temperature would still be below 62.5°C. The actual performance was measured and the following steps were taken to improve it. Kelvion completed the installation and upgrade of the Propane Condenser with the following parts: ► New fan shaft with top and bottom bearings, ► New fans
Results: This condenser was the main bottleneck of the plant, limiting the process flow rate. After upgrading the fin fan unit, new site measurements showed that airflow was increased by 53% and process flow rate was increased to 380.2 t/h @ 49.5°C with a lower outlet process temperature giving more flexibility to operate the unit during higher ambient temperatures. End-user was fully satisfied with the revamp.
