New Delhi, Dec 7 (IANS) Indian Oil Corp (IOC) is researching and developing a marker system to check adulteration of fuel, Minister of State for Petroleum Panabaka Lakshmi said Friday.
In a written reply to parliament, Lakshmi said that (IOC) has been advised to develop an in-house marker to detect adulteration of petrol and diesel with kerosene.
Public distribution (PDS) kerosene is priced much lower than petrol and diesel.
The minister said an effective marker requires gas chromatography (GC)-based technology and IOC is exploring development of a portable GC based detection device.
The marker system is not the first of its kind to check the adulteration of high-end fuel in the country. The oil industry first introduced blending of kerosene with furfural for the purpose in 1990.
However, furfural is toxic and posed problems in blending, especially at port locations, where large quantities of kerosene from the parallel marketing network entered the market with the liberalisation of the oil sector.
Subsequently, bio-markers like Oronite and Spectrace markers were also experimented with in the oil industry. However, the operational issues of correct dosage and availability of test-kits were a major deterrent.
