P2R units

Various oily residues are produced (pipeline cleaning, contaminants, tank bottoms), but most of them come from ships, which ensure 90% of the world's merchandise transportation. There is a strict regulatory framework (IMO, MarPol) but its implementation is difficult and costly. To comply with these rules, oily waste producers most often have to pay to have their waste collected and/or treated. Unfortunately still leads nowadays to some illegal dumping and discharge at sea or in rivers. Buying back these oily wastes is an incentive for producers to get them collected and treated, and helps the collectors to be sustainable. After the water and sediment have been removed, the P2R unit then upcycles these residues into several types of new commercial products, compliant with international standards. The distillation scheme, specifically designed in order to treat slops which are variables by nature, involves atmospheric and vacuum distillation in successive steps.
