Management of Gas Condensate Storage and Handling Operations in the Niger Delta

Gas condensate storage and handling involves unique safety, environmental, and operational challenges owing to the high vapour pressure, low flash point, and complex hydrocarbon composition of condensate streams. This study examines the management practices for gas condensate storage and handling operations at gathering and processing facilities in the Niger Delta, drawing on operational reviews at facilities in Rivers, Bayelsa, and Akwa Ibom states. The research employs a professional operations management assessment methodology, combining facility walkdowns, operational procedure reviews, and structured interviews with operations supervisors. Management dimensions assessed include condensate storage tank design and inspection practices, vapour recovery system operation, loading/offloading safety procedures, spill containment and response readiness, and management of condensate hydrocarbon inventory. The study evaluates compliance with EGASPIN storage tank requirements and API 650 tank design standards, as well as the adequacy of vapour emission controls relative to NESREA volatile organic compound (VOC) emission limits. Findings indicate that vapour recovery units (VRUs) at several facilities operate below design efficiency due to inadequate maintenance, resulting in atmospheric VOC emissions exceeding regulatory limits. Condensate spill containment bunding is found to be deficient at two facilities where bund volumes are insufficient to contain the largest single tank volume. Recommendations include mandatory VRU performance testing, bund capacity upgrade to 110 percent of the largest tank volume, and development of a condensate management best practice guide for the Niger Delta operating environment.
