Further fuelwith low viscosity &highdensity causes bad ignition. Hence it is necessary to reduce density. The exact value of density which can cause bad ignition notknown-hence all memberssuggested to keep the same Density. Further due towater availability, it will not be possible to lower density. 55 35 730 60 60 Value is accepted alightly higher than recommendation - so it was accepted. 30 30 22 20 AMAI value was accepted for Grade-2 0.05-0.2 0.05 Refinery &other members do not agree to go lower at one stroke. Thiscan be considered in next revisions 1% 0.5% AMAI raised this issue that is why consumer shouldpay for water both in Vol. as well as in transporting. This was also supported by some members, but IOC(R&D) did not agree on technical reason that some water is absorbed in storage due tohigh tempt. And conveyed that in ISO&CIMAC standard also have 1%water. This was left to future revision. 0.1 0. 1 Though manufacturer wanted 0.25 but committee has agreed to keep 0.1 5% 2 to 2.5 Committee did not agree to reduce upto 2.5%. however it was conveyed that already Sulphur from 5%to 4has come, let Refinery get equipped for Sulphur removal then the value can be further ~eviewed 20-50 20 Refinery wanted Sodium limit to 100ppm as during crudeprocessing the major of injected NaOH to migrate the corrosion phenomenon in crude distillation tower &other equip. get distributed FO component Contd...... ..
