A booming interest in separation technologies

By Chemical Engineering |

Distillation and absorption are back. The AIChE Spring Meeting (San Antonio, April 28–May 2) proved it and the fall meeting to be held in November will muffle any doubting Thomases. During the late 1970s and early 1980s, I spent appreciable time on acid-gas absorption. I knew the amine and hot-potassium-carbonate processes fairly well. I remember giving an absorption presentation at a large Canadian chemical engineering conference. Seven speakers gave seven presentations to an audience that was comprised solely of: the seven speakers. The applauses were less than deafening. Oh, how times have changed. At the AIChE Spring Meeting, attendance at the Distillation and Absorption (D&A) sessions was historic. Henry Kister and Mike Pritchett did an excellent job of arranging the associated Topical Conference, but the waves of attendees who showed up for the Monday morning session honoring Tak Yanagi had the organizers gasping and scurrying for extra chairs. There were at least 100 attendees; generally, 40 is considered to be a good turnout. Tak is popular, but not that popular. Attendance at the D&A sessions was in fact very strong all week long. The neighboring Ethylene Producers Conference was attended by hundreds. The Safety…
