High Output AdBlue® Production Plant Capacity 600L/Hour

The EBR-150B production plant consists of four independent units:

1. Demineralization unit.

2. AdBlue® production unit.

3. Screw feeding unit.

4. Filling machine for bottles.

1. Demineralization unit

The plant is conceived to deliver 250L/h (5000L/day) of permeate stream with an electrical resistivity ≥10 MΩ.cm, starting from 0.8 m3/h of raw water with a maximum concentration of ions of about 800 mg/l (TDS) and conductivity is less than 1500µS/cm. This choice allows to cover most of the civil/industrial applications where it is expected to draw water from the local network (2 bars at least) by ensuring the production of high quality demineralized water (low conductivity) for industrial uses and, in particular, for the production of high purity AdBlue.

During this phase, the feed water passes through double stages of reverse osmosis under pressure. As result, water is split into two streams: the permeate (demineralized water) and concentrate (a concentrated solution of impurities).

The key functions and components of this stage are:

· Pre-filtration of the feed water through disposable filters, which are carbon filter, sands filter and resin filter.

· Dosage of antiscalant and dechlorinating product.

· Filtration through osmotic membranes and ion exchange or EDI(Electrodeionization in short, optional).

· Reading/control of in-line conductivity.

· Permeate and concentrate streams management (delivery/recirculation).

· Flushing management. 

     2. AdBlue® production stage

The scope of this phase is to produce AdBlue® by mixing under specific conditions the demineralized water with urea.

The key functions and components of this stage are:

· Loading the bag(s) of urea through the screw feeder or by workers. If using screw feeder, every time loading urea 300KG around. If charging urea by workers, every time loading urea 32KG around.

· Transferring water using the pump from the demineralized storage tank to the stainless steel mixing tank. The demineralized water could be heated in the stoarge tank. Heating the water until it reaches a defined temperature. The heating system is optional.

· The weight of urea and the demineralized water are measured by the weigh scales installed under the mixing tank.

· Starting the production of AdBlue® by combining the demineralized water with the urea.

· Simulate a vortex inside the mixing tank in order to create the proper conditions to load the urea. The pump is used to create the vortex.

· After completion of this stage and in accordance with the quality requirements (measured by the weigh scales) of the final product, the system will be ready to transfer the AdBlue to the outside storage tank. The pump is used to make this transferring through the double stages of filtrations.

· The entire system (demineralization and AdBlue® production stages) is handled by a Programmable Logic Controller (PLC) which manages among other things:

- The opening and closing of the pneumatic actuators valves, protection door.

- Flow of permeate and concentrate streams based on electrical conductivity.

- Quality of the product in accordance with the measurement of the weigh scales, the precision is 0.3%.

- The PLC can be connected to the Internet, and all condition of the machine could be checked remotely by the Bluebasic’s engineers.

      3. Technical specifications of the screw feeder

      4. Filling machine for bottles.

The scope of this phase is to filling AdBlue into 5L, 10L 20L bottles by manual workor. The filling machine contains an IBC tank on a weight scales, a circulation pump, a spray nozzle. The filling machine is also connected to the main machine, which condition can be monitored by PLC. In this phase, the compressed air is needed to control the spray nozzle.

The pressure of the compressed air: 4-6 bar.

Capacity: 1000L per hour.

Power: 370W.
