Maleic Anhydride  
maleic anhydride imageALMA maleic anhydride, jointly developed by Lummus Technology and Lonza SpA, is an advanced and economical technology for the production of maleic anhydride from n-butane. It combines the unique features of a fluid-bed reactor, such as energy efficiency and large single-train capacity, with a nonaqueous recovery system to produce the highest purity (99.9 wt %) maleic anhydride product currently achievable.
