Abstract

In this chapter, a number of traditional as well as novel technologies for acid gas removal from synthesis gas are discussed. For the traditional technologies, physical-, chemical-, and hybrid-solvent-based technologies are discussed. A number of novel technologies are under development, mainly with the goal of reducing the cost of CO2 capture. Some of these novel technologies are still at the lab-scale, while others are being evaluated at pilot-scale or higher. These technologies include various warm gas cleanup technologies ...
