Optimize CO2 removal

What selection criteria should be used when evaluating gas-processing methods to separate bulk CO2? Enhanced investigative techniques pare down technology options to a short-list

Many technologies efficiently remove carbon dioxide (CO2) from natural gas and other gas streams. With so many choices, there is no "one size fits all" solution. Consequently, process designers must align technological benefits of various techniques with the final product or downstream plant specifications. Choice is always beneficial for any decision. Yet, in this instance, the vast array of potential options to remove CO2 can create confusion. The presented guidelines demonstrate how to generate a short-list of appropriate technologies for CO2-removal applications. Many factors are involved in this exercise. Using an engineering consultant can 1) streamline the evaluation
