Title of Technology to be offered

A process for acid pickling inhibitor

Type of Technology

Indigenous

Area of Technology

Materials and Material Science

Brief description/abstract 

A unique inhibitor with no equals in the market. High molecular weight, multistrutural bonds and presence of localised electron density at active centres enable the product to be very superior in application, with  proven inhibition efficiency of over 90% at all operating concentration of acids and temperatures. It enables to reduce acid consumption by 30%, metals dissolution by 50% and fume generation by 80 to 90%

Major Raw Material

(a) Polymers of high molecular weight (b) Amine and thio-compounds etc. All are in digenously available

Major Plant Equipment/Machinery

(a) Tanks (b) stirrers (c) Filtration assembly (d) Vacuum pumps (e) weighing machine etc. All are indigenously available. Ideally suitable for small scale industry
