Pine oil pitch - fuel conversion for Skanska's asphalt production

News   •   Jun 19, 2019 08:49 UTC

Skanska's road to sustainable asphalt production continues together with Petro. At two asphalt mixing plants, Skanska converts its production to run on pine oil pitch instead of fossil oil. Pine oil pitch is a residual product in the production of pulp. It is to be considered a rather "difficult" bio-oil. It needs to be heated to about 110 degrees during combustion and it must be at least 65 degrees when stored. It is also very aggressive so all parts that come into contact with the oil must be in stainless steal.

Without demand for neither steam nor compressed air and with low oil pressure, Petro Low Pressure Air Burner is a very good choice for pine oil pitch. It is also robust enough to handle the difficult environment of an asphalt mixing plant without any problems.

Petro has developed a whole product line for pine oil pitch, all the way from storage, via pump and heating unit to the burner. The entire system is specially designed to handle aggressive and thick oils like pine oil pitch.
