s. CHARACTERISTICS PROPOSED BY BIS COMITTEE WARTSILA AM AI REMARKS No. FORDG FORDG METHOD OF REQUIREMENT RECOMMENDATION GRADE-1 GRADE-2 TEST REF. TO (P) IS:1448 11.' Vanadium ppm 300 300 ICAP/D-3605 100- 600 100 No proven technology is available to reduce Sodium carryover owing to this phenomenon. But committee did not agree to increase limit as it is equally harmful for DG set components IOCR wanted Vanadium limit upto 600 ppm as imported fuel some time have vanadium 300 ppm or more. But committee &AMAI did not agree. 12. Aluminium + Silicon 80 80 ICAP/D-3605 30 20 This was not accepted by Refinery manufacturer as due to basic fuel have ppm Max; more value and under present refinery processing removing of Silicon is difficult rather they wanted limit to 100 ppm. However, committee has agreed to80ppm. This needs review in future. 13. Ashohaline, %by 10 14 IP- 43 14 14 mass Max: 14. Accelerated dry sludge 0.1 0.1 ASTMD 4870 None Nil This is the best value and will save sludge and quality fuel will be good. This content %by wt. Max: IP 390 test will be on the basis of Refinery- Not at user end or supplier end. ISO 10307 15. Soot test for Faint or Faint or ASTMD 4770 None No.2 Test will be carried out at the time of supply. cleanliness poorly poorly defined defined inner inner RIN RIN 16. Soot test for Faint or Faint or ASTMD 4770 None Homogenous soot Test will be carried out at the time of supply. Compatibility Ratings poorly poorly No.2 defined defined inner inner RIN RIN 17. CCA I ....TO be reported.... CCAI = D-81-141 Log(V+0.85) =4831og(T+2731323) D= Density in kg/m2 at 15 deg.C V= Kinitic viscosity in cast at Temp. 1deg. c 18. NCV kg/k cal. ....TObe reported.... More than 9950 Presently committee agree to report as no"body was agreeing to fix.However, on insisting committee agreed to report. Note :-Refinery members insisted that quality of fuel will depend on typeof storage and handling of F.O. Thisarea also need equal care.
