Title: DESIGNING MOLECULAR SIEVE DEHYDRATION UNITS TO PREVENT UPSETS IN DOWNSTREAM NGL/LPG RECOVERY PLANTS

Ortloff has designed four cryogenic NGL/LPG recovery units over the last 10 years where undesirable transient effects due to the upstream dehydration system design have been observed. In each of these facilities, the switching of a freshly regenerated mole sieve bed led to temperature and, in some cases, compositional disturbances at the inlet to the cryogenic unit, which then propagated through the entire unit over a 15-30 minute period. These disturbances caused process excursions which affected the recovery level of the unit, plus introduced some undesirable temperature variations at the heat exchangers. Ortloff has a perspective on the challenging conditions for the switching valves.
