Ecoslops technology

Ecoslops has an innovative technology, enabling the processing of oil residues into valuable new products (new fuels and light bitumen).

Ecoslops is the cleantech that brings oil into circular economy. Its first industrial-scale processing unit has been operational since June 2015 in the port of Sinès, Portugal.

Ecoslops technology is based on:

• perfect control of the collection, processing and refining processes of slops and sludges from maritime transport

• a major innovation that combines treatment of oil residues and refining techniques applied to marine litter

With its integrated and innovative approach, Ecoslops offers port infrastructure, waste collectors - maritime and terrestrial- and ship-owners a cost-effective, environmentally friendly solution that complies with international and European regulations regarding the collection and processing of slops. In this respect, Ecoslops has concluded several commercial agreements, notably with European shipowners and collectors.

The hydrocarbon residue reprocessing unit is the heart of the Ecoslops technology. It is a major innovation in the sector. Thanks to its refining process, Ecoslops transforms collected slops into a perfectly usable fuel (Naphta - Diesel Oil - Fuel Oil). The Ecoslops industrial site is the first in the world to produce new fuels that comply with international standards. Ecoslops technology is also compliant with international standards for gaseous emissions and liquid and solid emissions.

Ecoslops technology is based on several steps fully integrated:

→ Advantages

… Hydrocarbons, water and sediments separation

In order to guarantee an optimized distillation, the slops are heated, decanted and centrifuged to separate the water, the hydrocarbons and the sediments before the distillation process. This step allows Ecoslops to produce new fuel and light bitumen with 98% yield.

… Water treatment

At Ecoslops, the reprocessing of the water from the slops is fully integrated with the treatment process

Collected water are depolluted using the most recent techniques. It is then returning to natural environment according to international and local environmental laws.

… the P2R column

the unit of hydrocarbon waste treatment: heart of Ecoslops’ technology

Ecoslops made a significant breakthrough by combining a number of sophisticated refining techniques into one micro-refining unit, compared to traditional refining units producing oil. This innovation was made possible due to the advanced refining processes used in a sized reduced treatment unit compared to usual fuel refining plants and technology and specifically developed engineering that makes these processes applicable to slops recycling.
After the water and sediment have been removed, the slops are sent to the P2R vacuum distillation column. The slops are heated to 400°C, which, under vacuum conditions, causes most hydrocarbons to vaporize. At the end of the distillation, several types of fuels are produced.

The P2R column has a hydrocarbon fraction treatment capacity of 100 tons per day.

… the Scarabox^®(Mini-P2R)

A containerized mobile unit for ports of regional importance

The Scarabox^®(Mini-P2R) unit opens the revaluation of petroleum waste to more than 300 medium-sized ports, thus encouraging the treatment of these residues in a traceable and transparent way.
Ecological and economically sustainable, the Scarabox^® is also a source of diversification for ports and creates sustainable jobs for the energy transition.

The Scarabox^® has a hydrocarbon fraction treatment capacity of 3 000 to 6 000 tons per year.
