Pure Energy Separator LIFE09 ENV/SE/000352 - Pure Energy Separator - Innovative Centrifugal Separator Technology for Energy Recovery and Oily Waste Volume Reduction
Overview
Background & policy context:
The global shipping industry, comprising vessels over 400 gross tonnes (approx. 60 000 vessels), consumes 410 million tonnes/yr of fuel oil. Some 0.5% of this fuel is lost during the process of separating the oil from dust particles. During this process the discarded oil is mixed with water and stored in sludge tanks for further treatment. This waste oil is usually incinerated on board the vessel or on shore.
Objectives:
The overall objective of the ‘Pure Energy Separator’ project was to demonstrate and evaluate a new, innovative continuous ejection technology, based on a new method of expelling sludge from a separator. The system was not expected to require any process water and therefore the sludge was to be concentrated and dry, with the result that more than 90% of the waste oil could be reused. The volume of oil going for incineration should then have been reduced, which was in line with the objectives of the Directive for the Disposal of Waste Oils (75/439/EEC).
