Safe
The real “NO-MAN ENTRY”
No toxic emission in the air
Inerted closed-loop system
What is the S.R.S.® about?
It is the real NO MAN ENTRY system.
Nuova Saimar S.r.l. designs, manufactures and sells the S.R.S.® (Sludge Recovery System), an automated, mobile and modular, non-manned oil tank cleaning system based on the C.O.W. technology.
The S.R.S.® crushes the sludge and fluidize the hydrocarbons contained, by using the same product that has generated it, recovering up to the 98% of the hydrocarbon contained in the sludge.
How does it work?
Compared with the traditional tank cleaning method, Nuova Saimar S.R.S.® [Sludge Recovery System] is safer, quicker and cheaper.
What grants the maximum personnel safety is its “closed loop” operation system. Sludge crushing is reached by the mechanical action performed by special rotating nozzles (called “Jet Washers”) that, installed on the tank roof, direct high-pressure jets on all the tank surface. This allows a chipping action of the solid part, that scatters and dissolves, thanks as well to the chemical action given by the fresh oil towards the sludge.
After a proper percolation, the fluidized (mixture between the hydrocarbon contained in the sludge and the “fresh” oil) is given back to the Client, generating additional value and cost saving.
Deposit remaining inside the tank after S.R.S.® operations is generally composed of 1/3 of water, 1/3 of sediments and 1/3 of hydrocarbon. The high percentage of hydrocarbon recovery allow the operators to enter the tank without any health risk, as no trace of hydrogen sulphide remains.

A-Unit
A-Unit is used to suction oil from the tank to be cleaned and to transfer the processed oil to an oil receiving tank. A water ring type Vacuum Pump collects the liquid inside an accumulator and from here transferred to the B-Unit or directly to the Client’s pipelines.
Flammable gas passing through the vacuum pump are then sent back to the tank under cleaning: this procedure allows a safe workplace and keeps a positive pressure inside the tank.
Liquid level inside the accumulator, as well as the hollow that allows extraction, is monitored by an automated system that regulates their functional organisation.
B-Unit
The B-Unit is used to feed washing oil into Nuova Saimar Jet Washers installed on the tank roof. The pipe bundle heat exchanger assembled on this Unit may be used to heat both the oil and the water needed for tank washing, depending on the cleaning stage.
The use of the A-Unit in connection with the B-Unit has the following advantages:
- Two centrifuge pumps (a Recovery Pump and a Washing Pump), both witha flow capacity of 180 m3/h @ 10 bar, that can be used jointly;
- During the disassembly of the provisional lines, at the end of the operations, these can be easily cleaned by using the vacuum pump and the accumulator assembled in the A-Unit.
Separator Tank
Separator Tank is a sealed tank with an hydraulic tank cover used in the final water washing to divide oil from water.
Inside, that tank is divided in two by a partition, that allow the oil in suspension to “fall”. Water can be then heated again and sent back to the Jet Washers or, in case final washing has ended, given back to the Refinery.
Jet Washer
This technologically advanced rotating nozzle is the heart of the S.R.S.® technology. The last enhancement gave the Jet Washers AM-70 a mechanical system of pneumatic movement that allows an angular rotation, on 360°, and an orbital rotation. When used in “all-round” mode, the synergy between the two allows the nozzles to cover a spherical surface. Nozzles can be used also on a “repeat” mode, that allows to select a specific angolar range that is periodically repeated.
- Maximum stem diameter: 70 mm (to be installed on the roof legs support of floating roof tanks)
- Fluid intake line: 3” flange (UNI or ASA)
- Supply: 90 m3/h @ 7 kg/cm2
- Rig Power: air motor, maximum pressure 6.1 kg/cm2
- Washing Angolar Range: [45° – 105° – 45°] or [105° – 140° – 105°]
- Total length: 1’950 mm – Weight: 45 kg
Oxygen Monitor
To prevent explosion risks due to electrostatic charges created by Jet Washers operations, an inert gas – usually nitrogen – is injected from roof sockets. The purpose is to maintain, all along the operations, the inner oxygen percentage below 8%. A specifically-made monitor analyses the atmosphere in six different sampling points and records 24/7 the oxygen percentage observed. Passing from one point to the following can be carried out both automatically and manually.
