Salt transport with a multi-stage pump system

About the project

***, Tessenderlo, Belgique Transport of salt to an electrolysis factory

We were confronted with the following task:
The filling of the storage tanks in the electrolysis plant is necessary up to 4 times a week. Until now, the salt was transferred from an inland vessel to trucks and transported to the electrolysis plant via country roads. About 80 truckloads are needed for one unloading operation. The salt is then transported over a distance of about 12 km. Since the storage tanks have to be filled four times a week, up to 320 truck transports through densely populated areas are required per week. This does not include the empty runs back to the canal. This kind of transport is associated with a lot of noise, dust and exhaust fumes for the residents.

Equipment

Technical details & challenges The pressure pipeline exists. However, it is an old pressure pipeline made of PE with DN 200, 204.6 mm l.w., so that a pressure rating of PN 16 could no longer be achieved with the existing pipeline (ageing of the material). The pipeline length is approx. 5,672 [m], PE pipeline DN 200, 204.6 mm l.w.. In addition, the pipeline was comprehensively examined for the risk of frost. Due to the saturated brine solution, the stationary system can remain filled in normal winter without freezing. A small pump keeps the circuit moving at about 20 [m³/h]. Most of the pumps can also be operated closed, or the pipelines are laid 90 % frost-proof in the ground. Due to the circuit pumping, the system can be operated with a circuit pump without additional solids loading.

Our solution To meet the requirements, 6 pumping stations were installed. The saturated salt solution is fed into a mixing station. The dry salt is transported by a dredger from the barge to the mixing station. The brine absorbs the salt and transports it to a storage tank without dissolving the salt. The brine is pumped back to the mixing station without loading it with raw salt. This is possible because the brine is saturated. This means that the salt introduced can no longer be dissolved, or only in very small quantities. The system therefore pumps in a closed circuit.

Used pumps 6 HPK 150/450 armoured pumps with APFlex® lining for discharge pipe lengths:

Pump 1 - delivery distance from quay 757 m
Pump 2 - approx. 1195 m
Pump 3 - approx. further 1201 m
Pump 4 - approx. further 1216 m
Pump 5 - approx. another 560 m
Pump 6 - approx. further 300 m

Salt transport with a multi-stage pump system

For the salt transport on the pipeline length of approx. 5,672 m, we have designed and implemented a multi-stage pumping system. This avoids up to 320 truck transports per week through densely populated areas. By using our solution, residents are no longer burdened by noise, dust and exhaust fumes.
