Traditionally, the chemical engineer can rely on chemical separation
methods such as distillation, crystallization, extraction, and
adsorption. This paper presents a process technology for continuous
separations based on ion exchange, adsorption/desorption, and
chromatography. Key advantages and demonstrated process examples are
included.
Calgon Carbon introduced its ISEP® (ion exchange and adsorption)
and CSEP® (chromatography) technology in 1990. The systems are now
installed in more than 300 operating units worldwide. The systems have
demonstrated significant advantages over traditional
approaches.
From a unit operation perspective, the ISEP process can replace
traditional fixed bed adsorption, ion exchange, and chromatography
processes and become increasingly more valuable as the process
complexity increases.
