In this issue we focus on improvements in process technologies used within the industrial gas industry that are raising energy efficiency and cutting costs. Praxair explains its new process technology for Direct Reduced Iron that uses a variety of fuels such as coke oven gas (p. 36).
Catacel updates readers on its Stackable Structural Reactor for steam methane reforming (p. 40), and Linde files a report on special oxygen burners and gas technologies that make aluminum recycling much more efficient (p. 42).
This report looks at a few of the many improvements being made to air separation processes and technologies. Major industrial gas companies and air separation unit (ASU) equipment manufacturers have been developing technology and equipment to make improvements in the very complex air separation process—advances that minimize power per unit of output and reduce capital expenditures and other controllable costs, such as maintenance and labor. Improvements have been applied to new ASU plant design as well as in retrofits to existing plants.
