VOC Abatement Filters - Specifications

The tanks where the filters are to be mounted must be built to API 650 and maintained in accordance with API 653 or EEMUA159 (Alteration Repair and Maintenance of tanks).

The dimensions and physical size of the filter depends on the tank size, surface area and maximum pump rate for each tank. The tank’s pumping rates are important factors for the correct design of the filter surface in order to remain within the maximum allowable pressure/vacuum during the operation.

Breather valves are installed parallel to the adsorption filter with settings complying to the maximum allowable pressure and vacuum of each tank to avoid break down and mechanical damage.

In case of overfilling of tanks, mechanical damage or blockage by dirt in the Adsorption Filter, the breather valves will ensure continued operation and the tank ventilation will continue to function in accordance with the specifications for each individual application.

Tank Odour Filters - Advanced options

Depending on environmental legislative requirements or if the hydrocarbon concentration is higher than 50 gram/m³, one or more of our safety options may be required.

Option 1 – Forced Ventilation

Forced Ventilation is recommended for Tanks with high evaporation ie. light products or products with a low flash point. The option can be fitted with a backup system (redundancy).

Option 2 – Automatic Shut-off valve

The Shut-off valve option is triggered by sensors for either Carbon Monoxide (CO) or temperature (or both) and can be installed between the filter and the tank to ensure that a rise in temperature in the filter (hot spot) will be isolated from the tank at a set-point well below the flash point of the tank content.

Option 3 – Water Mist System

A Water Mist System can be inserted in the filter to cool the filter or, in emergencies,drench the Active Carbon; preventing or extinguishing a fire inside the filter, which could be caused by hot-spots.

Option 4 – Flame Arrestor

A flame arrestor can be inserted between the filter and the tank to prevent vapours from igniting inside the filter. A flame arrestor do not function as a fire protection by itself, and it is therefore recommended that other measures are taken to ensure that an ignition (hot spot) is extinguished either by a built-in fire protection system as per above or by an on-site emergency response team.

Option 5 – PLC Automated Control Cabinet

This option enables various alarm settings and reaction patterns to be programmed in combination with one or more of the above options.

Other options for specific applications are available.

Customized Tank Filter Systems

The Go4 Tank Vent system with Carbon Odour Filter eliminates odour problems from Storage Tanks for Oil and Oil products, thereby avoiding complaints and claims from neighbours, particularly in residential areas.

The Filter and Accessories meet EU Directives, local legislation and customer specific requirements.

The tanks must be built to API 650 and maintained in accordance with API 653 or EEMUA159 (Alteration Repair and Maintenance of tanks). Breather valves should be installed in parallel to the filter complying with the max. pressure and vacuum to avoid break down and damage. In case of overfilling of tanks, mechanical damage or blockage by dirt in the Adsorption Filter, the breather valves will ensure continued operation.

Customization requires some basic information to enable us to calculate the dimensions and other data for the filter and breather valves. Larger or more complex installations will require a site visit to inspect the tank(s) and possible grouping of filters.
