The complete paper discusses carbon-capture processes and applications in the steelmaking industry from an economic point of view. Carbon capture is an expensive process, which can create hesitation in implementation. However, this process has not been properly quantified, which is the authors’ primary goal.

Introduction

The first portion of the complete paper describes the primary techniques used in carbon capture:

  • Chemical absorption
  • Physical absorption and membrane separation
  • Precombustion
  • Oxyfuel and partial oxyfuel combustion
  • Direct air capture

The Steelmaking Industry

Two main raw products are used in steelmaking. The primary raw product is iron ore, while the secondary raw product is steel scrap.
