Definitions
- the present invention concerns a pretreatment method of emulsified fuel for eliminating impurities contained in the emulsified fuel and a supply method of emulsified fuel for supplying a diesel engine with emulsified fuel as fuel.
- bitumen, asphalt, tar or other heavy oils of high viscosity have been emulsified by adding water, because they are hard to pipe line transportation.
- Such emulsion can be used as fuel for an internal combustion engine (Japanese utility model application Kokai publication No. 1984-96351).
- the emulsified fuel to be injected into a cylinder from a fuel injection atomizer is not atomized sufficiently, increasing the concentration of particulate matter in the exhaust gas.
- the present invention has been made in order to solve such problems, and has an object to provide a pretreatment method of emulsified fuel that can eliminate easily impurities contained in the emulsified fuel, without destroying the emulsified fuel.
- Another object of the present invention is to provide a supply method of emulsified fuel capable of controlling the concentration of particulate matter in the exhaust gas.
- the pretreatment method of emulsified fuel according to the present invention is characterized by that an emulsified fuel which is emulsified by adding water and surface active agent to Orinoco tar is heated to 70 °C to 95 °C and, at the same time, introduced in a centrifugal separator at a flow rate of 0.35 Q to 1.0 Q for eliminating impurities contained in the emulsified fuel.
- Q is the actual capacity of the centrifugal separator in case of clarifying in the centrifugal separator a heavy oil of 380 cSt in viscosity at 50 °C by heating to 98 °C.
- emulsified fuel a slurry fuel emulsified by adding a trace of surface active agent to about 70% of Orinoco tar and about 30% of water, namely "Orimulsion” (brand name) is preferable.
- This Orimulsion is produced and commercialized by PDVSA Bitor Inc., a government enterprise of South American Venezuela.
- the temperature of emulsified fuel supplied to the centrifugal separator is preferably in a range of 70 °C to 95 °C. In case where the temperature of the emulsified fuel is less than 70 °C, it is hard to separate impurities. On the contrary, in case where the temperature of the emulsified fuel exceeds 95 °C, the emulsified fuel becomes unstable, and tends to destroy easily.
- the flow rate of the emulsified fuel supplied to the centrifugal separator is preferably in a range of 0.35 Q to 1.0Q, and more particularly, in a range of 0.35 Q to 0.90Q.
- Q is the actual capacity of the centrifugal separator (standard flow rate determined by the manufacturer of the concerned centrifugal separator) in case of clarifying in the centrifugal separator a heavy oil of 380 cSt in viscosity at 50 °C by heating to 98 °C.
- the flow rate of the emulsified fuel supplied to the centrifugal separator is less than 0.35Q, the emulsified fuel stays longer in the centrifugal separator and tends to destroy easily.
- the flow rate of the emulsified fuel supplied to the centrifugal separator exceeds 1.0Q, as the flow rate increases, the impurities removal efficiency particularly decreases, making the clarifying difficult (See Fig.2).
- impurities separated from the emulsified fuel by the centrifugal separator are discharged out of the centrifugal separator preferably with a time interval of 1 to 3 hours.
- emulsified fuel When impurities separated by the centrifugal separator are discharged out of the centrifugal separator, emulsified fuel is discharged with impurities, the discharged emulsified fuel can not be used as fuel for diesel engine.
- the supply method of emulsified fuel of the present invention is characterized by that an emulsified fuel which is emulsified by adding water and surface active agent to Orinoco tar is heated to 130 °C to 160 °C after clarifying or non-clarifying and supplied as fuel to a diesel engine.
- the temperature of the emulsified fuel supplied as fuel to the diesel engine is preferably in a range of 130 °C to 160 °C . In case where the temperature of the emulsified fuel supplied to the diesel engine is less than 130 °C, the emulsified fuel injected into the cylinder from the fuel injection atomizer is not atomized sufficiently, increasing the concentration of particulate matter in the exhaust gas.
- Fig. 1 is a schematic view of a pretreatment equipment for performing the pretreatment method of emulsified fuel according to the present invention
- Fig. 2 is a graph showing the relation between the solid impurities separation efficiency (%) and the flow rate (Q) of Orimulsion to be supplied to the centrifugal separator. Best Mode for Carrying out the Invention
- Orimulsion (brand name) a in an Orimulsion storage tank 1 is pumped up by a first pump 3 and supplied to a first heater 4 through a first filter 2.
- a part of iron rust detached from the Orimulsion storage tank 1 or a piping 21 and of solids such as sand contained in the Orimulsion a are caught by the first filter 2.
- Orimulsion supplied to the first heater 4 is heated to 70 °C to 95 °C, before supplied to the centrifugal separator 5 with a flow rate of 0.35 Q to 1.0Q.
- Q is the actual capacity of the centrifugal separator 5 (standard flow rate determined by the manufacturer of the concerned centrifugal separator) in case of clarifying in the centrifugal separator 5 a heavy oil of 380 cSt in viscosity at 50 °C by heating to 98 °C.
- the temperature of Orimulsion a is controlled by the quantity of hot water to be supplied to a heating jacket (not shown) of the first heater 4.
- the flow rate of Orimulsion a is controlled by regulating the rotating speed of the first pump 3. 22 indicates a piping connecting the first heater 4 and the centrifugal separator 5. Impurities such as rubbish, gravel or iron rust are eliminated from the
- Orimulsion a introduced in the centrifugal separator 5 for clarifying.
- the clarified Orimulsion a passes through the piping 23 before being stored in an Orimulsion service tank 6.
- a diesel engine 11 is started using diesel oil b in a diesel oil service tank 7.
- fuel supplied to the diesel engine 11 changed gradually from diesel oil b to the clarified Orimulsion a'.
- the Orimulsion a ⁇ in the emulsified fuel service tank 6 is pumped by a second pump 8, and supplied to a second heater 9.
- Orimulsion a ⁇ supplied to the second heater 9 is heated to 130 °C to 160 °C, before being supplied as fuel to the diesel engine 11 through a second filter 10 and a piping 24.
- is controlled, for instance, by the quantity of superheated steam to be supplied to a heating jacket (not shown) of the second heater 9.
- 25 indicates a piping connecting the diesel oil service tank 7 and the piping 24.
- the aforementioned piping 24 is provided with a first flow regulating valve 26 upstream the second pump 8, and the piping 25 is provided with a second flow regulating valve 27.
- Orimulsion a can be supplied to the diesel engine 11 without eliminating impurities contained therein.
- an emulsified fuel which is emulsified by adding water and surface active agent to Orinoco tar is heated to 70 °C to 95 °C and, at the same time, introduced in a centrifugal separator at a flow rate of 0.35 Q to 1.0 Q for eliminating impurities contained in the emulsified fuel, allowing to eliminate easily impurities contained in the emulsified fuel, without destroying the emulsified fuel.
- an emulsified fuel which is emulsified by adding water and surface active agent to Orinoco tar is heated to 130 °C to 160 °C after clarifying or non-clarifying and supplied as fuel to a diesel engine, allowing to atomize the emulsified fuel injected into the cylinder from the fuel injection atomizer and, on the other hand, prevent water of the emulsified fuel remaining in the fuel injection atomizer from evaporating during the exhaust stroke.
- the concentration of particulate matter in the exhaust gas discharged from the diesel engine can be limited.
- the pretreatment method of emulsified fuel having the aforementioned excellent effects can be used effectively for eliminating impurities contained in the emulsified fuel.
- the supply method of emulsified fuel can be used effectively for controlling the concentration of particulate matter in the exhaust gas discharged from the diesel engine.
