Abstract
The disclosure relates to an anti fouling composition including a metallic component comprising of at least one alkali metal salt and a non-metallic component and method for preparation of anti fouling composition. The disclosure also relates to a process of reducing fouling in reactors or furnaces using said composition.
Claims20
An anti-fouling composition comprising:
- a metallic component selected from the group of alkali metal salt, alkaline earth metal salt, transitional metal salt, salt of tin, and combinations thereof;
- and
- a non-metallic component comprising urea and ammonium oxalate,
- in effective amounts for anti-fouling, wherein the metallic component weight ratio is in the range of 50 to 95% with respect to the composition and the non-metallic component weight ratio is in the range of 5 to 50% with respect to the composition.
A method for preparation of a composition for mitigation of foulants in reactors, the method comprising:
- contacting a non-metallic component selected from the group of urea, oxalic acid, succinic acid, tartaric acid, EDTA, ammonium oxalate, ammonium acetate, ammonium sulfate, sugar, and combinations thereof, and a metallic component comprising a nitrate salt of sodium and a nitrate salt of potassium at a weight ratio of 1:1 to 4:1 with water in effective amounts for anti-fouling to form a mixture, wherein the metallic component is in a weight ratio of 60 to 90% and the non-metallic component is in a weight ratio of 10 to 40%;
- and
- removing the water from the mixture to obtain the composition.
An anti-fouling composition comprising:
- a metallic component comprising a nitrate salt of sodium and a nitrate salt of potassium at a weight ratio of 1:1 to 4:1;
- and
- a non-metallic component selected from the group of urea, oxalic acid, succinic acid, tartaric acid, EDTA, ammonium oxalate, ammonium nitrate, ammonium acetate, ammonium sulfate, sugar, and combinations thereof,
- in effective amounts for anti-fouling, wherein the metallic component weight ratio is in the range of 60 to 90% with respect to the composition and the non-metallic component weight ratio is in the range of 10 to 40% with respect to the composition.
