Abstract: A process for the preparation of an alkylene glycol from an alkene is provided, along with an absorber apparatus. The process comprises: supplying a gas composition to an absorber comprising a column of vertically stacked trays, wherein each of the vertically stacked trays comprises: a perforated gas-liquid contacting member or members, a liquid inlet area, an outlet weir extending vertically above a surface of the tray at an opposite end of the tray from the liquid inlet area and having a height of at least 200 mm and at most 1500 mm, and a downcomer element which, in cooperation with an inner surface of a wall of the column, forms a downcomer for the passage of liquid downwardly to the liquid inlet area of an adjacent vertically stacked tray below, and allowing the gas composition to pass upwards through the alkylene oxide absorber.

Abstract: The invention provides a reaction system for the production of ethylene carbonate and/or ethylene glycol. The system having a guard bed system upstream of a catalytic EO reactor. The guard bed system having a feed line supplying a gaseous feed to be treated and an effluent line configured to remove the treated gaseous feed. The guard bed system has two or more guard bed vessels arranged in series in sequential order, each having an inlet, a bed of guard bed material and an outlet. The inlet of each guard bed vessel is attached by means of valves to both the feed line and the outlet of the guard bed vessel preceding it in sequential order. The outlet of each guard bed vessel is attached by means of valves to both the effluent line and to the inlet of the guard bed vessel following it in sequential order.

Abstract: A process for the preparation of an alkylene glycol from an alkene comprising steps of: a) supplying a gas composition to an alkylene oxide absorber through a gas inlet, the absorber comprising an absorption section and a sump, and allowing the gas composition to pass upwards; b) supplying a lean absorbent to the top of the absorption section and allowing the lean absorbent to pass downwards; c) intimately contacting the gas composition with lean absorbent in the absorption section in the presence of one or more catalysts that promote carboxylation and hydrolysis; and d) withdrawing fat absorbent from the absorption section and passing the fat absorbent and any liquid condensate through the sump, wherein the sump comprises one or more baffles that define a flow pathway from a sump inlet to a sump outlet between the one or more baffles.
