HYCOL Process

HYCOL Process (16,17). The HYCOL process is similar to the Destec (Dow) process in its use of a two-stage entrained-flow gasifier. The char that the lower-temperature top stage produces recycles to the hotter (slagging) bottom stage. The key difference is that the HYCOL gasifier is dry fed, whereas the Destec gasifier is water slurry fed.
