Abstract:
Method for drying the charge of a unit that treats petroleum cuts with a low water charge, comprising a step of infecting into said charge a quantity of a chemical compound which is soluble in said charge chosen from the group consisting of:a metal halide replaced by hydrocarbonic radicals with a formula of M1XyR1nR2m where M1 is a metal chosen from the group consisting of aluminum, gallium and indium, X is a halogen, R1 and R2 are hydrocarbonic radicals, the value of y is 1, 2 or 3 and the values of m and n are 0 or 1, the sum of n and m is not equal to zero and the sum of y, n and m is equal to 3, a metal halide replaced by the hydrocarbonic radicals with a formula of M2XzR1jR2kR3l, where M2 is a metal chosen from the group consisting of titanium, tin, germanium and zirconium, X is a halogen, R1, R2 and R3 are hydrocarbonic radicals, the value of z is 1 or 2 and the values of j, k and l are 0 or 1, the sum of j, k and 1 is not equal to zero and the sum of z, j, k and l is equal to 4, a metal compound replaced by hydrocarbonic radicals with a formula of M3R1R2R3R4, where M3 is a metal chosen from the group consisting of titanium, tin, germanium, and zirconium and R1, R2, R3 and R4 are hydrocarbonic radicals, a metal compound replaced by hydrocarbonic radicals with a formula of M4R1R2R3 where M4 is a metal chosen from the group consisting of aluminum, gallium and indium and R1, R2 and R3 are hydrocarbonic radicals, where the quantity of the chemical compound injected is at least equal to the quantity necessary for all the water contained in said charge to react by hydrolysis with said chemical compound.
