5.1 Introduction

One of the most important parts of corrosion management in the oil and gas industry is to pay close attention to process additives, solvents, and beds. Depending on the design, each of these materials can be used in a single unit operation and perform in such a way that will require the process designer to redesign. Therefore, a process will inevitably lead to one of the following:

• Energy consumption will increase significantly,
• Equipment volumes will be calculated extremely large,
• Material selection will be very expensive,
• The land required to erect the processing site will be very large,
• For achievement of guaranteed quality (and in some cases quantity) of the products, a large amount of money will be spent to make their production non‐competitive or impossible.

This chapter aims to provide a model of effective management of process additives (EMPA), chemicals, on the processing site. Industrial cases have been presented with the approach of the effects of potentially ineffective management of chemicals on equipment corrosion. The natural gas processing industry has been chosen as the platform for studying and extracting potential cases and operation histories. Among these, the scope of unit operations ...
