Lummus Technology offers an array of commercially well-proven, patented etherification technologies for the production of high-quality ethers. These technologies are based on the unique catalytic distillation (CD) process, which combines reaction and fractionation in a single unit operation, not only reducing investment cost, but allowing reactant conversion beyond equilibrium values. The processes employ the use of an acidic ion exchange resin catalyst in both the reactor and proprietary CD structures referred to as CDModules®.
