Simulation of VOC Emission During Loading Operations in a Crude Oil Tanker

“Volatile Organic Compounds” (VOCs) are known to contribute significantly environmental pollution. Crude oil loading operations in a marine tanker produces significant quantity of hydrocarbon (HC) vapours the surrounding atmosphere. A large percentage these HC vapour emission consists ‘Volatile Compounds’ (VOCs). This VOC has not been previously analysed detail understand health and impact. The scope study reported this paper demonstrates use chemical processing simulation software (Aspen HYSYS ®) model identify VOCs during crude operations. objective is determine detailed variation volume composition hence, VOCs, as level ship's tank rises while being filled influence temperature pressure on extent emission. Total per tonne calculated compared with other similar field measurements. analysis identifies concentration toxic emission, well liquid fraction lost operation. data for between 10°C 45°C from empty 90% full. resulting information useful assess impact efficiency current Potential recover monetary loss by increasing installation 'VOC Recovery Unit' analysed.
