Louisiana Chemical Equipment Company

Overview
Unused C3 splitter designed by Linde Engineering convert refinery-grade propylene (75-77%)
and/or chemical-grade propylene (90-92%) to purified propylene (98.25%) and propane. The
unit includes 4 process sections: (1) Dryer, (2) C3 Stripper, (3) C3 Splitter, (4) Treatment. The
process flow involves pre-drying the refinery grade propylene in molsieve (3A) dryers, followed
by stripping in a column to remove light ends. The chemical grade propylene is fed directly into
the splitter column due to its higher quality. The splitter column has two different feed trays to
accommodate both feeds at their optimum point. Further purification of the propylene product
occurs through a series of regenerative and non-regenerative treaters to eliminate components
potentially detrimental to the polypropylene process. Regeneration systems for both refinery
grade raw propylene (dryers) and regenerative propylene product treaters are integrated into the
package. Vessels under nitrogen blanket. Full technical documents available.
