This 321 stainless steel, high-pressure stripper column system was designed by ICI and built by Whaley Engineering, LTD. The column is rated for 353 psig at 350oC and typically ran at about 250 psig and 200oC. The system used live steam to strip light components from a maximum flow of 7.9 m3/hr of crude methyl amine product (932 kg/m3 density).
The 321 stainless steel (10.5% Ni) column is 2.0' diameter by 64' straight side. It has a design pressure of 353 psig @ 350oC. The column volume is 5,820 liter and it has three, 10' high packing sections with 1" stainless steel (321) pall rings. The column has an internal overhead condenser mounted in the top head. It also has an overhead stream cooler as well as two bottoms coolers. There are four feed interchangers for heating the feed with the column bottoms stream.
