 The entity of Mercury element in the raw material of the Ethylene plant (Diesel) .i

 Mercury ( Hg ) .i

 It is a chemical element with an atomic number (80). It is a silver fluid with density 13.54 g\c.m, under 38.9°of heat; freeze and looked blue silvered.i

 Entity :i

 The mercury element can be found in the raw material ( The Diesel ) which be broke thermally to produce ( Ethylene, Propylene, ..etc ), this raw material is provided by the refinery of Raslanuf which depended to LERCO company " The Libyan Emirates Processing Company ".i

 1i- Negative effects on the catalyst which used in the reactors in the Ethylene plant.i

 2i- Damaging the Aluminum plates of the thermal converters in the cold box.i

 3 - Damaging some parts of the Rinthlaby which made in Aluminum.

 Taken Procedures:

 A meeting was held between LERCO, AGOCO and RASCO to execute tests on the raw oil samples and the product of Diesel.
