Functional description

All components of the product are placed on an off-road-truck. Thus, the machine is deployed for mobile applications and the work-location can be changed. The truck has been approved for use on public roads.

Off-road-truck

A double-walled cryotank can be found to the rear of the truck load area. The cryotank is filled with liquid nitrogen and provides the nitrogen to the pumping unit. The cryotank is installed to a skid, certified in accordance with ADR and may be transported using public roads with the appropriate labelling and qualification of the driver.

Nitrogen tank

A pump unit can be found to the front of the truck. A diesel aggregate is used to power the hydraulic motors and pump flow. The heat generated by the motor and hydraulic components is used for the nitrogen evaporation process.

Pump unit

The liquid nitrogen is supplied to a triplex pump and brought to the desired discharge pressure by the lifting piston. The liquid nitrogen that is now under high pressure then flows through the nitrogen / water heat exchanger, is vaporized, heated to a temperature of 20 °C and made available for further processing procedures – e.g. to the coiled tubing unit – via a transfer interface. The transfer of heat energy between the water circuit / nitrogen circuit is undertaken via a vaporizer. An operator cabin can be found between the nitrogen tank and the pump unit. The machine can be controlled and monitored using the control platform.

nitrogen is returned to the nitrogen tank via the return flow (20/2).

High pressure The liquid nitrogen is applied with intense pressure in the pressure cylinders of the triplex pump (20/4) and pushed to the vaporizer (20/5) via the high pressure line. The liquid nitrogen is vaporized in the vaporizer by means of heat energy from the water circuit and heated to a temperature of 20°C. This results in a strong volume intensification (1 litre LIN = 697 litres gaseous N2) and pressure increase. The pressure by the triplex pump must be kept as high as such, that more and more liquid nitrogen is ed into the vaporizer. The now gaseous and tempered nitrogen is released via the transfer interface (20/6).

4. 5.

The nitrogen tank can only be filled by personnel who have been especially trained and instructed to carry out this task. Make sure that the working area is kept free of obstacles, that the delivery vehicle has a secure access route. The emergency routes must be kept clear. Make sure that the type and data plates are present on the tank, well legible and match the certificates of the inspection organization / designated body. Make sure that the time period for the latest tank inspection period has not been exceeded.

Check before filling

Inspect the nitrogen skid, the nitrogen tank and the safety-relevant components before you start the filling process. The nitrogen tank may only be filled if all criteria listed have been complied with (see chapter 12.3).

10.2.3 Initial filling New nitrogen tanks and nitrogen tanks, which have been stored for extended periods, must have a residual amount of nitrogen and a low pressure in the internal container. This is necessary to prevent any moisture from penetrating. These tanks must be flushed with nitrogen before initial filling. The internal tank must not be colder than the boiling point of liquid nitrogen in this case (-195.79 °C). The liquid nitrogen can freeze if filled into a tank that is too cold. This results in incalculable pressure ratios and entails a high risk. The nitrogen tank is warm during the initial filling.  After the container has been filled with liquid nitrogen, open the gas exhaust valve (V4) and the cock valve (V3) or (V15) to thoroughly cool down the container.  Close the gas exhaust valve (V4) and the cock valve (V3 or V15) after the container has cooled down.

Operation Cool down

7. Open the RAPID COOL DOWN VALVE. This valve is found on the operator and can be actuated from the operator cabin.

As soon as the RAPID COOL DOWN VALVE is opened, liquid nitrogen flows into the low pressure circuit of the N2 pump from the nitrogen tank. The liquid nitrogen very quickly absorbs heat energy and vaporizes. In this instance, the pipe lines and components / boost pump are intensely cooled – recognizable by the frost formation. The gaseous nitrogen is discharged into the environment via the pipeline. The outlet point is found on the left side in front of the operator cabin.

This procedure must be carried out until the nitrogen at the outlet point es from gas into liquid. The boost pump can only pump liquid media.

Instructions Manual



Version 01, [12.07.2016] Page 121 of 182

Operation Cool down

In the meantime, test whether the boost pump already has liquid nitrogen flowing through it. For this purpose, carefully actuate the BOOST PUMP SPEED CONTROL rotary switch (Figure 45/2) on the control and observe the LN2 BOOST PRESSURE gauge (Figure 45/1). The boost pump is ready for use as soon as a constant pressure is maintained.

10.3.6 High-pressure pump The circuit switches to the high-pressure pump as soon as the low-pressure circuit and the boost pump are prepared. The high pressure pump has a "warm" Power End and a "cold" Fluid End working area. The Fluid End area must be cooled down before operation of the pump. The following figure shows the area coloured in blue.

Operation Pumping nitrogen

10.3.7 Return flow The return flow to the nitrogen tank is established once the lowpressure circuit has cooled down (liquid nitrogen is blown out of the outlet point). Only liquid nitrogen is conveyed back into the tank via the return flow line.

1. Open the by valve V-12 below the main valve. 2. Close the by valve once again as soon as liquid nitrogen emerges at the valve outlet.

3. Open the valve V-1 for the return flow at the nitrogen tank incrementally. The reflux volume flow into the tank must be adjusted to the operating conditions here.

Cooling down and preparation of the N2 pump is thus completed. The N2 pump is now ready for operation.

10.4 Pumping nitrogen Discharge quantity, pressure and temperature of the nitrogen intended for pumping are variables, which are defined and determined by the customer. This is implemented using programming at the N2 pump.

The operating mode has a significant influence on the level of contamination and the service life of the plate heat exchanger. The media should be operated with the highest possible volume flow (according to the device specification) if possible. If the volume flow is too low or in the case of partial load operation, turbulence in the plate heat exchanger may decrease while the contamination tendency is greater. In the case of operating temperatures of more than 60 °C, calcium deposits will result dependant on the quality of the water. These reduce heat transfer efficiency.

Version 01, [12.07.2016]



Required for the maintenance

Acid-based cleaning agents

Phosphoric acid  Concentration max. 2%  Temperature max. 20 °C  Exposure time approx. 1 hour

or

Lye-based cleaning agents

Caustic soda  Concentration max. 4%  Temperature 85 °C  Exposure time 24 hours

Implementation of the maintenance If there is contamination or formation of deposits in the flow gaps due to the water or media quality, then the plate heat exchanger must be rinsed out. This takes place – if possible – in reverse flow, i.e. against the actual direction of flow. Only carry out all cleaning work with chloride-free or lowchloride water of low hardness and then flush with plenty of water until the acid is completely rinsed off the plate heat exchanger and the adjacent pipelines. If chemicals are used for cleaning, then these may not affect the materials of the plate heat exchanger nor the lines or components or the machine. The plate heat exchanger will be destroyed if these notes aren't observed. The safety regulations and recommendation of the cleaning agent manufacturer must be strictly observed in this instance.
