Definitions

  • the present invention relates to a process for treating petroleum residues and more particularly marine petroleum residues such as slop oils and sludges and recovering valuable products such as light fuels, heavy gas oil and heavy fuel oil. Said process is called "P2R”.
  • the present invention also relates to a modular unit for recycling said petroleum residues.
  • Said pollution is mainly due to accidental or illegal "degassing", corresponding to the rejection of motor oil and motor fuel residues into the sea.
  • Slop oils and sludges are emulsions of water and oil containing solid sediments.
  • the proportion of each of said three phases is very variable from one emulsion to another; however, the aqueous phase is often the major phase, representing 40 to 80% of the mixture.
  • WO-A-2004/067137 discloses a mobile device for reprocessing hydrocarbon wastes such as slops into valuable products, particularly heavy fuel oil and naphtha by atmospheric distillation. Said device for reprocessing slops has the drawback of not efficientlyzing a heavy gas oil side cut useful as marine diesel fuel or bunker.
  • the applicant has worked out a process for treating decanted petroleum residues and recovering valuable products based on vacuum distillation which allows to obtain about 20 to 70% heavy gas oil useful as marine diesel fuel and about 20 to 70% heavy fuel oil useful as feedstock for cement works, boiler plants, power plants or flux oil for bitumen, the remaining being light fuels used as internal fuel for the process.
  • Said process has the capacity of treating up to 1000 tons/day of petroleum residues.
  • the present invention also relates to a modular unit for carrying out the above process.
  • An object of the present invention is to provide a process for treating petroleum residues and recovering valuable products comprising the steps of:
  • the treated petroleum residues are more particularly marine slop oils and sludges.
  • figure 1 is a schematic diagram of one embodiment of the process and unit according to the present invention.
  • the petroleum residues can contain solid particles, chemical waste, or any other pollutants, in a quantity compatible with valorization of heavy fuel oil and heavy gas oil.
  • the petroleum residues feed the unit through pump (P001) and are preheated in a heat exchanger (E001) at a temperature from 90°C to 150°C.
  • V001 flash drum
  • E005 condensed in the condenser
  • D003 decanted water
  • T001 tank
  • P005 Liquid light fuels are driven through pump (P006) and line 4 to tank (T002).
  • Incondensable gases (5) are burnt in the burners of the heater (H001).
  • Dehydrated petroleum residues are driven through pump (P002) to the heater (H001) wherein they are vaporized at 300°-410° C.
  • the heater produces steam in connection with a steam drum (D001).
  • distillation column (C001) which operates under a vacuum of at least of 250 mbars absolute. Distillation allows splitting the feedstock into three cuts:
  • the top cut is condensed in a condenser (E002).
  • the condenser (E002) will be replaced by a pump and a cooler.
  • the liquid in the reflux drum (D004) is separated into two phases:
  • Non-condensable gases from the reflux drum (D004) are driven to drum (D003) through a vacuum system (S001). They are then driven through line 5 to the burners of the heater (H001).
  • non-condensable gases are evacuated through line 7 to blow down drum.
  • Water separated in drum (D003) is conducted through pump (P005) and line 6 to tank (T001) of decanted water and is then driven to a water treatment.
  • the medium cut comprising heavy gas oil is directed to a stripping column (C002) which regulates the flash point of heavy gas oil by a superheated steam flow produced in the heater (H001).
  • a reflux of heavy gas oil from the stripping column (C002) returns to the upper part of the distillation column (C001).
  • Heavy gas oil is driven through pump (P004), heat exchanger (E004) and line 3 to tank (T003).
  • Heavy fuel oil is driven from the bottom of the distillation column (C001) through pump (P003), heat exchanger (E003) and line 2 to tank (T004).
  • Regulating means are provided for controlling:
  • the heater (H001) is heated by burning incondensable gases extracted from drums D004 and D003 through line 5 as well as light fuels produced as the top cut of the distillation column (C001).
  • a vacuum system (S001) produces a vacuum of at least 250 mbars absolute (maximum absolute pressure) in the distillation column (C001).
  • the flash point is measured according to NF EN ISO 2719.
  • the viscosity is measured according to NF EN ISO 3104.
  • the density is measured according to NF EN ISO 12185.
  • One of the advantages of the process of the present invention is its flexibility with regard to the specified characteristics of the outlet products.
  • the operating conditions can be adapted to reach specified characteristics of the outlet products.
  • the percentage of each outlet product is strongly dependent on characteristics of inlet petroleum residues.
  • a further object of the present invention is to provide a modular unit for recycling petroleum residues and recovering valuable products which comprises:
  • the unit of the present invention further comprises storage tanks for decanted water (T001), light fuels (T002), heavy gas oil (T003) and heavy fuel oil (T004).
  • T001 decanted water
  • T002 light fuels
  • T003 heavy gas oil
  • T004 heavy fuel oil
