Abstract: The invention relates to a device and method for distributing a liquid and gas in a multiple-bed downflow reactor, such as a hydrocarbon processing reactor, like a hydrocracker. The device comprises respectively the method uses a distributor device comprising a substantially horizontal collecting tray provided with a central gas passage. Gas passing in downward direction through the central gas passage is forced into a swirling motion by a swirler. This swirling motion has a swirl direction around a vertical swirl axis so that the gas leaves the central gas passage as a swirl. At a location above the collecting tray, a quench fluid is ejected into gas in an ejection direction, which is, viewed in a horizontal plane, at least partly opposite to the swirl direction.

Abstract: A method to provide a fractured subterranean formation is provided, the method including the steps of: providing a wellbore from a surface location to the subterranean formation; applying a friction reduction treatment to at least a portion of an inside surface of a casing; cementing the casing with the applied friction reduction treatment into at least a portion of the wellbore; and pumping into the wellbore a fluid at a pressure that exceeds a fracture pressure of the subterranean formation thereby forming at least one fracture within the subterranean formation wherein the fluid is in contact with at least a portion of the inside surface of the casing with the applied friction reduction treatment.
