SCENARIO FOR THE SECTOR
Biorefining plants

Biorefineries are industrial plants capable of converting raw materials into bioproducts or biochemical substances for the polymer, cosmetics, pharmaceutical industries, biofuels, food, feed, and other materials.

“The biomass to be converted can be of various kinds: waste, wood, sugar, straw, corn, and even algae.
These raw materials are regenerable, which means that they can be reintegrated by nature relatively quickly, making biorefineries an example of the renewable energy industry.”

The transformed biomasses can be sugar, starch, wood, oils and fats of various kinds, and waste

The transformed biomasses can be sugar, starch, wood, oils and fats of various kinds, and waste. All these biomasses can be processed through:

From these processes, we obtain bio-materials based on wood, paper, fibers, polymers, biofuels, chemicals, pharmaceuticals, lubricants, surfactants, energy, and heat.

THE PROBLEM

The customer who contacted PNR Italia is one of the most important manufacturing companies in wheat biorefining in Northern Europe. Through the biorefining of wheat, they obtain starch, gluten, animal feed, and glucose syrup. They work for the paper, food, and livestock industry.

The need was to effectively clean the grid of a condenser inside the biorefining plant. Before PNR Italia’s intervention, the grill was cleaned only by a nozzle placed centrally above the condenser.

LA SOLUZIONE

PNR Italia’s technical office developed a system of manifolds and nozzles whose spray could uniformly cover the grid to ensure a much higher level of cleanliness than the previous single nozzle system.
A three-arm manifold is suspended at 30cm from the grid with a total of 6 full cone D nozzles that spray 2% water and soda at 80 °C

ADVANTAGES

The solution guarantees excellent coverage of the grid. Before the intervention, the flow rate was 2.5m3/h with a single nozzle. After the intervention, the total flow rate of six nozzles is 4m3/h.
