Studying the inhibition efficiency of the synthesized novel surfactants on the corrosion of heat exchanger tubes during chemical cleaning

Abstract

The work discusses the corrosion inhibition of carbon steel and copper-zinc alloy in 1M HCl solution by four synthesized inhibitors A1, A2, S1 and S2. In this work, the inhibition effects of those compounds have been studied by several experimental methods. This work contains three chapters:- Chapter 1:''Introduction'' This chapter includes a general introduction about corrosion (definition, economic cost, forms, factors, prevention and types of inhibitors), heat exchanger (definition, classification) and surfactants (definition, classification and applications). Chapter 2: ''Materials and experimental techniques'' The experimental part included complete description of synthesis of inhibitors and all details of measurements as the following: 1- Synthesis of inhibitors * Synthesis of novel amides * Synthesis of cationic surfactants
