Dow will install its fluidized catalytic propane dehydrogenation technology at one of its ethylene crackers in Plaquemine, Louisiana, adding 100,000 metric tons per year of propylene capacity.

Dow says its technology reduces greenhouse gas emissions by up to 20% compared with conventional dehydrogenation technology.
