Using nanotechnology liquid to suppress volatile organic compounds in tanks heralds a new, safer, era in tank cleaning
The new vapour suppression technology, marketed under the name NanoVapour, is due to be launched at London International Shipping Week (8-13 September) and consists of a liquid nano-suppressant and a hardware delivery unit.
The NanoVapor vapour suppression system is said to reduce the time needed to achieve a gas-free condition in confined spaces by up to 90%, making tank cleaning, maintenance and inspections much safer and faster at the same time.
The liquid nano-suppressant and the delivery unit work together to produce and then insert tiny nano-droplets of suppressant molecules into the tank using a high-flow air stream. The molecules work microscopically to quickly stop the evaporation of volatile organic compounds (VOCs) throughout the entire tank. It is even effective with residual fuel or sludge remaining in the tank, while fully preserving ambient oxygen for safe entry. The nanotechnology is completely non-toxic, non-corrosive, non-reactive, and biodegradable; it is completely safe for human contact.
During London International Shipping Week, Ecochlor’s business development officer Andrew Marshall will introduce the patented vapour suppression system to shipowners and managers. Mr Marshall said “This nanotechnology will revolutionise tank cleaning and gas freeing of cargo and bunker tanks in preparation for drydock or tank inspections for emergencies or maintenance. Additionally, it can be used to facilitate faster tank cleaning procedures required due to fuel switching for the new global sulphur cap regulations, allowing vessels to get back to normal operation as quickly as possible.”
NanoVapor’s chief executive Russ Chew said “Our vapour suppression systems have been successfully applied across the transportation industry for many years, including commercial aviation, retail underground tanks and inland marine. We have been designated a global ‘best practice’ standard by Shell Oil for the degasing underground petrol tanks for maintenance and inspections.”
NanoVapor is currently undergoing review for Lloyd’s Register type-approval.
