A humidification system (A) for humidifying a dry hydrocarbon stream includes a column ( ) which defines an interior cavity ( ). The cavity is partially filled with a bed ( ) of a packing material ( ) and a layer of water ( ), leaving a headspace above the water. An inlet ( ) adjacent a lower end of the cavity receives a dry hydrocarbon stream which is broken up by the packing material and dissolves water as it passes therethrough. Entrained water droplets fall out of the wet blend in a disengagement zone ( ) above the water layer leaving the hydrocarbon stream humidified yet substantially free of liquid water in an upper region ( ) of the column.

A continuous process for producing conjugated diene polymers comprising the steps of contacting, within an hydrocarbon solvent and within a continuous reactor, conjugated diene monomer and a catalyst composition prepared by combining: (a) a lanthanide compound, (b) an alkylating agent, and (c) a halogen-containing compound, and maintaining a non-ideal flow pattern within the continuous reactor so that 10% of the reagents entering the reactor at a reference time tare still present within the continuous reactor at a time t+xt, where tis the residence time corresponding to ideal flow within the continuous reactor and x is a numeral greater than 1. 5.

A process for the continuous polymerization of monomer, the process comprising (a) adding monomer and catalyst to an annulus within an annular reactor to form a polymerization medium within the annulus, where the annulus includes the space between an outer casing wall and an inner tubular wall, (b) allowing the polymerization medium a sufficient residence time within the annulus to provide a living polymer product, and (c) removing the polymer product from the annulus.

A group of compounds defined by the general formula (I) can be used to anionically initiate polymerization of unsaturated monomers. In the formula, M is an alkali metal atom, Ris an aryl group having at least one ORsubstituent group where each Ris a group that is nonreactive toward M, and R is a hydrocarbyl group. The subject initiators can be used in semi-batch and continuous polymerization processes, even those which are performed at elevated temperatures.
