Specification

I/We Claim:
1. A formulation comprising:
a) at least one first amine; and
b) at least one second amine,
U@ wherein the at least one first amine to the at least one second amine weight
ratio is in the range of 8: 1 – 10: 1.
2. The formulation as claimed in claim 1, wherein the at least one first amine to the
at least one second amine weight ratio is 9: 1.
3. The formulation as claimed in claim 1, wherein the at least one first amine has a
QP@ weight percentage in the range of 50 to 95 % with respect to the formulation.
4. The formulation as claimed in claim 1, wherein the at least one first amine is
selected from the group consisting of diethanolamine, morpholine,
monoethanolamine, diethylaminoethanol, triethanolamine, cyclohexylamine,
piperazine, methyldiethanolamine, ethyl ethanolamine, aminoethyl piperazine,
QU@ and combinations thereof.
5. The formulation as claimed in claim 1, wherein the at least one second amine has a weight percentage in the range of 5 to 15 % with respect to the formulation.
6. The formulation as claimed in claim 1, wherein the at least one second amine is a product of epichlorohydrin and the at least one first amine.
RP@ 7. The formulation as claimed in claim 1, wherein the formulation optionally
comprises at least one additive having a weight percentage in the range of 0 to 5
% with respect to the formulation and selected from the group consisting of
surfactant amines, ionic liquids, and combinations thereof.
8. A process for preparing the formulation as claimed in any one of the claims 1 -
RU@ 7, the process comprising:
a. obtaining the at least one first amine;
b. obtaining the at least one second amine;
c. contacting the at least one first amine, the at least one second amine, and
optionally the at least one additive to obtain the formulation.

9. The process as claimed in claim 8, wherein the at least one second amine is a reaction product obtained by contacting epichlorohydrin, and at least one first amine at a temperature in the range of 40 60 ℃ for a period in the range of 2 -4 hours.
10. The process as claimed in claim 8, wherein contacting the at least one first amine, the at least one second amine, and optionally the at least one additive to obtain the formulation is carried out at a temperature in the range of 25 ℃ - 60 ℃ for a period in the range of 10 minutes 120 minutes.
11. A method of reducing fouling in a petroleum refinery comprising, adding the formulation as claimed in claim 1 to a water system.
12. The method as claimed in claim 11, wherein the water system is in an oil refinery overhead system.
