Abstract: Disclosed is a method for preparing methyl methacrylate (MMA), the method including: (1) separating isobutene containing saturated hydrocarbon (n-butane and iso-butane), via a catalytic distillation process from a stream of C4 hydrocarbons containing butadiene, n-butene, and isobutene; (2) producing methacrolein via a first oxidation reaction of the separated isobutene; (3) producing methacrylic acid via a second oxidation reaction of the produced methacrolein; and (4) esterifying the produced methacrylic acid with methanol. By having a high heat capacity, the amount of nitrogen added is minimized to reduce the size of the reactor and the amount of gas production at a rear end, which has a high economic feasibility due to the effect of reducing investment and investment cost.

Abstract: A method for treating a natural gas containing carbon dioxide using membrane modules which are assigned to a first treatment stage or a second treatment stage and are fluidically connected to a retentate mode or a permeate mode. When evolution in the operating conditions results in one of the processing levels requiring less membrane surface for gas processing and the other processing level requiring more membrane surface for gas processing, then the method allows for reassignment of needed membrane modules assigned from one processing level requiring less membrane surface to another processing level requiring more membrane surface.
