A method for the oxidation of ethylene to form ethylene oxide which comprises: providing an aqueous stream containing ethylene glycol and impurities; introducing the aqueous stream in a first ion exchange treatment bed to reduce the content of these impurities; determining whether an outlet of the first ion exchange treatment bed has a conductivity greater than about 5 &#x3bc;S/cm; upon determining that the outlet of the first ion exchange treatment bed has a conductivity greater than about 5 &#x3bc;S/cm, introducing the outlet of the first ion exchange treatment bed into a second ion exchange treatment bed; and upon determining that the outlet of the first ion exchange treatment bed has a conductivity greater than about 60 &#x3bc;S/cm, redirecting the introduction of the aqueous stream to the second ion exchange treatment bed and regenerating the first ion exchange bed.

Epoxidation process

An improved catalytic hydration process that includes a catalytic hydration reaction section containing adiabatic reactors with ion exchange resin catalyst and which maintains low resin swelling and excellent selectivity while also reducing process complexity and increasing versatility.

Process for preparing ethylene glycol

Recirculating process for preparing ethylene glycol

A method for improving the manufacture of an existing ethylene glycol manufacturing that includes inserting a catalytic hydration reaction section with multiple adiabatic reactors.

Method for improving the manufacture of ethylene glycol

Described herein is a process for producing an alpha olefin by obtaining a feed stream of internal olefins having a first carbon number and alpha olefins having a first carbon number. The olefins are isomerized to increase the quantity of the alpha olefins. The olefins are then fractionated, subjecting the overhead material to catalytic metathesis to produce a mixed olefin effluent of internal olefins having a second carbon number and other hydrocarbons. The first isomerization reactor and fractionator are prepared to receive the olefins having a second carbon number, where the internal olefin intermediate is isomerized in the prepared first isomerization reactor. The second isomerization effluent is fractionated in the prepared first fractionator to separate the alpha olefins having the second carbon number from the internal olefins having the second carbon number. A corresponding system is also described, along with a heat pump that may be incorporated into the process.
