RB-5 EVOLUTION OF FUEL OIL SLUDGE FORMATION IN THE COOSUR POWER PLANT ( Aceites Coosur S.A. – Spain ) by using “rb bertomeu” additives
1 – BACKGROUND
COOSUR power plant is located in VILCHES (Jaén - Spain) and it is composed by 2 Wärtsilä engines type 12V 46 B , working on fuel-oil, with a power of 10,5 MW each one.
The plant was started up on March 1999 using Sspanish fuel oil No. 1, without additive.
After being operated during 2 years in this condition, the plant decided to use the fuel oil additive "rb bertomeu" beco F1/ASF starting in April 2001, in order to improve the global economy of the installation.
The present report shows the good results achieved by COOSUR regarding the reduction in fuel oil sludge and also in lubricanting oil sludge ( both generated in their corresponding purifiers during the plant operation) , since they started the treatment of fuel oil with the additive "rb bertomeu" beco F1/ASF, as they have enough comparative data referred to the years 2000 , 2001 and 2002. All data shown below have been supplied by COOSUR.
The most important data is the reduction in the generation of fuel oil sludge because it means very important save in fuel (organic sludges not generaterd are consumed as fuel) and save in transport and destruction of that sludge by an authorized company.
Observed decreasing in generation of lubricating oil sludge is also indicated as one more data to be taking into acount when the profitability of "rb bertomeu" beco F1/ASF is evaluated
2 – FUEL OIL CONSUMPTION
Period Fuel additive Consumption (Tons)
Year 2000 none 21,809
Jan-Apr 2001 none 4,401
Apr-Dec 2001 beco F1/ASF 12,214
Year 2002 beco F1/ASF 16,500
Total without additive (Jan 2000 – Apr 2001) 26,210
Total with additive (Apr 2001 – Dec 2002) 28,714
3 – SLUDGE GENERATED IN THE PURIFIERS
Period Sludge of Fuel oil (Kg) Sludge of Oil (Kg)
Jan-Dec 2000 143,790 127,390
Jan-Apr 2001 59,440 23,820
Total period without additive
Apr-Dec 2001 49,967 62,533
Jan-Dec 2002 50,570 58,640
Total period with additive
4 – RATIOS GENERATED FUEL SLUDGE – FUEL OIL CONSUMPTION
· 4-1 Kg of Fuel oil sludge/T of Fuel oil consumed :
Period Jan 2000 – Apr 2001, without additive: 203,230 / 26,210 = 7.75 Kg/T
Period Apr 2001 – Dec 2002, with additive : 100,537 / 28,714 = 3.50 Kg/T
· 4-2 Kg of Lubricating oil sludge/T of Fuel oil consumed :
Period Jan 2000 – Apr 2001, without additive : 151,210 / 26,210 = 5.77 Kg/T
Period Apr 2001 – Dec 2002, with additive : 121,173 / 28,714 = 4.22 Kg/T
5 - CONCLUSION
The reduction of 54,8 % in fuel oil sludge generation, measured in the power plant of COOSUR, is into the range of reduction guaranteed by the use of the fuel oil additive "rb bertomeu" beco F1/ASF, which confirms, in this point, the economical profit of the treatment with this additive.
