Abstract

The process consists of submitting waste oils, having checked the quality of and accepted the oils, to a heat refining which yields a fuel that is similar to commercial light diesel oil as an end product, which allows diesel motors in an electric power production plant to be supplied directly. The facility has an oil storage yard (9), with a tank (4) at which dirty oil arrives after being accepted, from which it is supplied to dirty oil storage tanks (5) that in turn supply the same to the oil treatment plant (6) from which they move on to storage tanks (8) and finally to an electric power production plant (11) supply system to supply the electric power producing motor generators (13).

Description

    OBJECT OF THE INVENTION
  • The present invention relates to a used lubricating oil electric power generating process with which the lubricating oils are successfully transformed into a light fuel product capable of supplying classic diesel combustion high-speed motors of the kind used in a conventional electric power production motor-generator set.
  • The invention also concerns the facility for putting said process into practice.
    • BACKGROUND OF THE INVENTION
  • Present-day consumption of lubricating oils for both automation and industrial uses is very significant. Said consumption in Spain actually stands at some 500,000 T/year, which poses a serious ecological problem because such oils are largely illegally incinerated or simply dumped uncontrolledly, with the resulting environmental damage.
  • In an attempt at avoiding this problem, treatment plants are known for oils of this kind, capable of regenerating the used oil by means of centrifugation and filtration techniques, which allow a heavy fuel to be obtained and used as fuel in supplying medium-speed diesel motors for obtaining electric power.
  • The main shortfalls of these systems lie in that, since a low-quality fuel is obtained, namely heavy fuel, diesel motors especially designed to work with heavy fuel must be used, which consequently has a negative environmental and economic impact.
    • DESCRIPTION OF THE INVENTION
  • The process proposed by the invention fully solves the problems aforesaid by refining the oil in such a way that a light fuel may be ultimately obtained with a high calorific power, which may be used directly to supply high-speed diesel type motors, of the kind used in small and therefore cheaper electric power production motor-generator sets.
  • More specifically and in order to achieve the above, the process subject hereof relies upon putting an oil refining into practice that is based upon submitting the oil to a heating capable of causing it to crack, thereby for heavy to be separated from light hydrocarbons and for the polluting elements contained in the oil to be precipitated, and for obtain a light fuel without any contaminants to be ultimately obtained.
  • This means that the used lubricating oil will always be confined within the system, without generating any spills and therefore reducing environmental pollution to a minimum.
  • A facility has been devised to put this process into practice that includes a used oil receiving and discharging unit, an oil storage yard, an oil treatment plant, an electric power generating station and a similarly electric transformation centre, from which the power is sent out to be consumed.
  • More specifically, from the used oil receiving and discharging area, provided with the appropriate receiving tank, the oils are pumped to dirty oil tanks from which the oil is moved onward by pumps to be treated, whereupon light diesel oil is obtained and stored in tanks to ultimately, either directly or through auxiliary tanks, move into the supply system established at the electric power production plant, which is fitted with a battery of motor generators responsible for producing electric power that is sent on to the relevant consumption centre or to the network through the transformation centre.
  • Provision has been made for the existence of a small auxiliary tank, capable of supplying the power production plant in the event that there should be no useful fuel obtained through the process of the invention.
    • DESCRIPTION OF THE DRAWINGS
  • In order to provide a fuller description and contribute to the complete understanding of the characteristics of this invention, a set of drawings is attached to the specification which, while purely illustrative and not fully comprehensive, shows the following:
  • Figure 1.- Is a flow diagram showing the used lubricating oil power generating process subject of the present invention.
  • Figure 2.- Is a schematic plan view of the facility for putting the process of the preceding figure into practice.
  • Figure 3. Is, finally, an enlarged and likewise schematic close-view of the generating station or power production plant.
    • PREFERRED EMBODIMENT OF THE INVENTION
  • With reference to these figures, it will be apparent that the used oils, which may originate in the automotive sector, or be industrial lubricants or train, ship and other oils, and may contain the usual additives such as antioxidants, thickeners, detergents, antifoamants and metal particles from metal-metal friction, residual petrol or diesel oil, rust, soot and water, arrive at the receiving and discharging area (1), usually carried by tankers (2) and, having been suitably weighed, are discharged with the assistance of pumping units (3) and caused to enter a receiving tank (4), from which samples are taken to check their quality and whether they should be accepted or rejected at the facility.
  • After being accepted, the oil is pumped from the tank (4) to dirty oil tanks (5), for instance having a capacity of some 250 m3, moving onward from such tanks (5) and with the assistance of the said pumping unit (3), to be treated at a plant (6), at which it is refined by cracking. After this plant (6) refining stage, the oil moves on to tanks (8) where the resulting product, namely light diesel oil, is momentarily stored to be used for producing electric power.
  • This same storage yard, marked (9) in figure 2, also has a small tank (10) of suitable capacity to supply the electric power production plant (11) when no useful fuel obtained through the treatment of this invention is available.
  • From the storage tanks (8), the resulting fuel is pumped to auxiliary tanks (12), existing at the power production plant (11), each of which in turn supplies a battery of motor generators (13) which produce electric power that is sent to the network through a transformation centre (14) in which the appropriate high tension transformers are arranged.
  • Now, therefore, in accordance with the foregoing, the essence of the invention lies in obtaining a light diesel oil, capable of directly supplying the high-speed combustion motors (13) used in electric power production generating sets.
