9 Welke internationale regelgeving is er? EC benzinerichtlijn (1994/63) ADN Varend ontgassingsverbod van toxische stoffen (T) bij bruggen, sluizen en dichtbevolkte gebieden; tenzij praktisch niet uitvoerbaar Varend ontgassingsverbod overige stoffen bij sluizen en hun voorhavens Stilliggend ontgasverbod, tenzij hiertoe locaties zijn aangewezen. [Geen locaties aangewezen door MinIenM/RWS] Ontgassen onder voorwaarden, o.a. LEL (<50%) Niet tijdens onweer 9

10 Lokale regelgeving in Rotterdam Omgevingsvergunning: Alleen onder voorwaarden bij terminals HBV Rotterdam 2013: Geulhaven (Buoys 60) is bestemd voor ontgassingen na toestemming door de havenmeester Verbod om de volgende (13)stofgroepen te ontgassen, zoals opgenomen in bijlage III; o.a., benzeen (1114) Samenstellingen met meer dan 10% benzeen (verschillende nummers) 10

11 oplossingen Dedicatievaart (laden en lossen van hetzelfde product), Lading over lading op basis van een compatibiliteitslijst (niet conflicterende ladingen), Inzetten van technieken om de gasvormige ladingrestanten te herwinnen en terug te kunnen brengen in de productieprocessen Inzetten van technieken om de gasvormige ladingrestanten te verwerken. 11

Used nitrogen available on market, the condensors have defrost cycles AQ Linde can be emitted into air, Very high VOC recovery rate which takes extra time for degassing, an extra heat exchanger is necessary for condensed aerosols in the vapour flow Less suitable to treat high benzene concentrations due to solidifying of substance, Not yet available on market, Energy Recovered product can be obtained pure. Used nitrogen (Cryo-) condensation consumption will be higher due to two stage design. the can be emitted into air, With two stage techniques very Mariflex/purgit condensors have defrost cycles which takes extra time for high removal rates can be achieved. degassing, an extra heat exchanger is necessary for condensed aerosols in the vapour flow (membrane) filtration Condensation STS Ventoclean Recovered product can be obtained pure. Used nitrogen can be emitted into air, More suitable to treat high benzene concentrations due to controllable condensation temperature Adsorption Always has to be in combination with a scrubber or/and a condenser or for certain substances a specific design is Recovered product will be dissolved in the scrub needed, Boiling point of VOC substance must be above 30 medium, this can be avoided by using a condenser degree Celcius, Saturated carbon must be processed, instead of a scrubber but energy consumption will be Ignition of the coal is possible at high loading rates and higher, Small units can be installed on board of barges insufficient cooling, the condensation of an installation depends on many factors Vapour balance system No polution, high availability, no loss of substance Ionisation Relative quick handling time, no waste Biological treatment Environmental friendly Copyright - Port of Not yet available on market, Not very suitable for very volatile products, For very volatile products (such as MTBE), it will be difficult to reach low emission concentrations, Significant maintenance is required A potential re-use of the substances can be realised, which can create a sustainable and profitable solution Because this technique has a small(er) range of products which are suitable to process vapour it has a disadvantage in comparison to other technuiques Compared with the other techniques there still is a relative operational cost, due to the activated carbon. A potential re-use of the substances can be realised, which can create a sustainable and profitable solution This technique is less suitable to treat high benzene concentrations, this results in a shortterm disadvantage becuase the prohibitation is directed on benzene and benzene containing substances A potential re-use of the substances can be realised, which can create a sustainable and profitable solution This technique is less suitable to treat high benzene concentrations, this results in a shortterm disadvantage becuase the prohibitation is directed on benzene and benzene containing substances This technique has an oppertuinity in the raise of the demand of inert ships, becuase this technique makes vessels inert at the same time of vapour removal it benefits from this trend. A potential re-use of the substances can be realised, which can create a sustainable and profitable solution A potential re-use of the substances can be realised, which can create a sustainable and profitable solution This technique is not very suitable to treat very volatile products, this results in a smaller scope of products which can be degassed, this results in a smaller range of products which are suitable to process vapour and forms a disadvantage in comparison to other technuiques Due to the high availibility and proven working of the Not always meets standards of VBS in form of sustainability, technique it is possible to be used more often for the If one vessel is inert it will not acept the vapour form a vessel removal of vapours which is not inert, various substances which are balanced into the same tank may form an explodable mixture No recovery of substance, not yet tested, does not need Still in development phase, other techniques might the extra fuel like incineration process technical need before this technique is available VOC concentrations are too high, Operations flow must be Rotterdamcontinuous, low efficiency, the installation will require a lot of space This technique has a realtive short average duration, If one vessel is inert it will not acept the vapour form a vessel which is not inert, various substances which are balanced into the same tank may form an explodable mixture, this results in refusal for the degassing of of the vessel from the vapour processing facility if operational a more sustainable variation of incineration (no additional fuel needed) Operations flow must be continuous for this technique, this is not a realistic demand 12 This technique still has a impact on the
