Storage Lagoons, Ponds & Separators
NESL Lagooner
On many refinery sites, it is common for tank bottoms to be transferred to on-site lagoons and ponds. This enables owner/operators to free up vital ullage space otherwise wasted.
Once the material is transferred to the lagoons/pits it can be held until the owner/operator is ready to deal with it. Typically the material is left to settle so any oil floats to the top where it can be skimmed off.
The issue of space arises again as more material is pumped into the lagoon/pit. At some point the sludge will have to be dealt with. It is not uncommon for the sludge to be removed from site as hazardous waste, therefore, incurring a hefty disposal cost.
What most owner/operators don't realise is the value of the oil entrained in the sludge.

In response to growing demand, NESL designed and built the NESL Lagooner.
The Lagooner vehicle is lowered into the lagoon/pond where it mixes the contents before pumping the slurry to a sludge treatment plant.
The complete system consists of a single 20’ double door container with a built in electro-hydraulic power pack, Lagooner vehicle, umbilical, storage reel and control stand.
The Lagooner comes complete with a choice of on-board lobe pump with a pumping capacity of eighty-two cubic meters per hour *. For the removal of heavy sludge from the lagoon the unit is fitted a with rotating macerator front end which is interchangeable with other types of units.
NESL Separator Vehicle
The NESL API kit is designed for the effective cleaning of API separators, interceptors, lagoons etc. and is ATEX certified for use in an ATEX Group II Cat 2 Area (Zone 1) and as with all NESL equipment it will come with a full documentation pack complete with all testing and certification required.
The API Kit is available in two forms.
Clients that already have an NESL mover kit a conversion kit that allows the mover vehicle, reel and umbilical and power pack to be used for the base of the equipment.
The main component to the kit is the API unit. The unit simply slides into the track retention slots on the mover tracks and is bolted into position with the supplied locking bolts and all hydraulic hoses are included with the API unit for connection to the tracks.
The on-board lobe pump is connected to the suction blade via a vacuum rated chemical hose. The discharge line from the pump is not supplied and must be sourced by the customer. Connection details are supplied.
Clients that don’t already have a mover we also provide a complete system with all necessary components.
All controls for the kit are included. Power is supplied to the unit from the mover power pack. The 15mtr extension hoses are simply plugged straight into the control stand. The API vehicle umbilical is also plugged into the control stand.
A powered storage reel is supplied complete with umbilical for the unit. The reel comes with a simple hydraulic hand control valve for operation. Speed control is simple as is performed by adjusting the supplied flow control valve.
