Method for removing and recovering volatile organic components |
摘要 |
A method for the recovery of volatile organic components (VOC) released when loading liquid hydrocarbons into a storage or cargo tank, is described. The VOCs issuing from the tank are compressed, and injected into a sidestream taken from the main hydrocarbon stream, which is cooled and used as the absorbing medium, and is conducted to a VOC recovery unit comprising at least a bi-phase rotary separator turbine (BRST). In the BRST the VOC-containing gas is substantially separated into a VOC component and inert gas. The inert gas is vented to the atmosphere. The VOC component or VOC-enriched liquid stream is then returned to the main cargo stream or a cargo tank. Any methane contained in the volatile gases issuing from the cargo tank, instead of being vented to the atmosphere, is recovered or a catalytic process is used to convert methane to carbon dioxide and water for discharge to the atmosphere. The system is particularly intended for the offshore loading of oil into tankers.
