Development and application of the controlled freeze zone process

Conference ·
OSTI ID:5281871
The Controlled Freeze Zone (CFZ) process is a cryogenic distillation technique for separating carbon dioxide and heavier compounds from methane. This paper describes how the process controls the freezing and melting of CO/sub 2/ in a specially designed section of an otherwise conventional distillation tower. In addition to describing the process, the paper compares the CFZ process to other gas treating processes, discusses pilot plant operational results, and gives examples of potential CFZ applications.
