A clean outlook at oil refining and oil production

Competitive advantages

The mobile greenBLAZE Complex is designed for the disposal and recycling of all types of oil sludge from the oil production and refining industries, regardless of the complexity of their chemical composition and the amount of formation water they contain.

Delivery of oil sludge to the Reception Hopper (1) of the Complex is within the Customer’s area of responsibility. The receiving hopper is used to receive oil sludge and to create a stock of raw material to ecsure uninterrupted operation of the Complex within 3 hours.

The reclaim of oil-containing elements (oil, fuel oil, etc.) is up to 70% of their content in the initial oil sludge. This result is achieved by using a Centrifuge (2) with variable chamber geometry, which reduces the energy consumption of the Complex and increases its productivity per tonne of weight.

The separated water from centrifugation can be discharged back into the environment or, at the customer's request, sent to the Sewage Treatment and Neutralisation Unit (15), where it is removed and treated to any level, including discharge into a fishery pond.

The dewatered oily sludge after the centrifuge enters the Primary Treatment Chamber with Cracking Elements (3). In this chamber, the sludge is heated and partially cracked, releasing straight-run gasoline.

The unprocessed sludge in the primary treatment chamber (organic and non-organic compounds) enters the Liquid Fuel Converter Chamber (5), where under a dosed oxygen supply full deep oxidation and decomposition of oil products takes place, resulting in the output of synthesis gas.

The synthesis gas is then sent to the Synthetic Fuel Synthesis Reactor (6) to synthesise hydrocarbons. The gas fraction obtained in the reactor is sent to the Rectification Column (7). The liquid pro-oil products obtained in the rectification column are diverted to the Storage Tank (8).

The remains of inorganic compounds with a plume of undecomposed oil products go to the Afterburner Chamber (9) where the final removal of oil products from sludge is done by burning organics with the emission of heat.

The ash and slag, which has undergone final cleaning in the post-combustion chamber, and the ash cut off after the decomposition of petroleum products, flow through the Ash and Slag Diverter (10) to the Storage Container (11). The ash and slag are chemically inert and environmentally friendly, and can be used without further treatment as a filler for building materials.

The exhaust gases generated in the afterburner are fed to the Exhaust Gas Recovery and Cleaning Unit (12). In terms of pollutant emission limits, the Complex meets the regulatory requirements of the European Euro-5 standard and the Russian GOST RF 305-2013.

At all stages of oil-slime transportation (transfer) from the unit to the unit in the prescribed manner is carried out by sealed transportation devices of closed screw and conveyor type.
In order to provide the Complex with autonomouspower supply, the Complex is equipped with an Autonomous Generation Electricity Unit (13).

To monitor and control the complex, the following is used MCS (14).

The heat released in the afterburning chamber can then be used as thermal energy as a commercial product and as a source of electrical power generation.

The heat is delivered to the Electricity Generation Unit (17), which is a hydro-turbine, a closed loop water column with a tower height of 36 metres. The water from the tower falls onto the impeller of the hydro turbine, which drives 4 alternators with a rated capacity of 250 kW each. Having completed its work, the water is flung back to the top of the tower by an airlift effect, where it is temporarily stored in a storage tank and discharged again to the water turbine.

Residual heat, which is not fully utilised in electricity generation, is dissipated via the heat exchanger of the Heat Extraction Unit (18) and discharged to the atmosphere. In the future it may be possible for the customer to use the heat for commercial purposes (e.g. for ice and cold production - a proposal that can be considered as part of a separate project). As an additional option, the Synthesis Reactor (6) and the Rectification Column (7) can be replaced by aGas Turbine or Gas Piston Power Generation Unit (16).
