Process Description: Feed to the column could be as high as 7.9 m3/hr (7,400 kg/hr) of crude amine products at 250 psig and 180 deg C. The feed enters the column in the upper-middle section between the second and third packed-sections. An internal condenser is used in the top of this column to condense heavier compounds in the overhead stream. The condensed compounds are collected and further cooled in the overheads cooler before being sent to storage. The condensed overhead stream to the overheads cooler typically ran at only 0.1 m3/hr at 210 psig and 62 deg C but was rated for a maximum flow of 1.6 m3/hr. The piping is 2” diameter for the condensed overheads stream. The hot bottoms stream from the column is cross-exchanged with the incoming feed using four interchangers in series. The flow typically ran at 3.5 m3/hr @ 211 psig and 200 deg C but the system was rated for a maximum flow of 10 m3/hr. The feed was heated with these exchangers to 180 deg C. The bottoms stream was cooled by these interchangers from 200oC to 101oC. The bottoms stream was further cooled in the two bottoms cooler exchangers. These exchangers took the bottoms stream down to 30 deg C. Intermediate pressure steam was injected into the column bottoms at about 1.0 m/hr through a 3” nozzle to provide the stripping momentum
