Abstract
Considerable quantities of fuel oil additives are being consumed in Japan for diesel engines and boilers. However, no detailed figures on supply and demand of these additives have been published yet.
This interim report, based on 19 answers out of 50 questionnaires mailed to additive manufacturers and marketers, gives a brief outline of the survey sponsored by the Fuel Society.
According to the survey, annual consumption of fuel oil additives by these 19 firms totalled 20, 000 kiloliters: broken down into land (70percent) and marine (30 per cent) uses. The survey also disclosed that approximately 85 per cent of fuel oils being consumed by main engines for marine purposes use the additives, while approximately 45 per cent of fuel oils for auxiliary engines use the additives.
As regards the consumption for land purposes, primarily for pulp, chemical, textile, electrical machinery, and food industry uses, the additives are used by approximately 53percent of all fuel oils consumed.
