A method for installing a spray pipe, including an insertion step of inserting a spray pipe from an opening portion, a positioning step of positioning the spray pipe such that an installation surface of a leg portion faces a supporting surface of a supporting portion, a provisional tightening step of provisionally tightening a first fastening portion to couple an attachment flange with the opening portion, an adjusting step of adjusting the height of the installation surface relative to the supporting surface such that an axis along which a pipe portion extends coincides with the horizontal plane, in the provisionally tightened state resulting from the provisional tightening step, a coupling step of coupling the leg portion to the supporting portion by means of a second fastening portion, after the adjusting step, and a final tightening step of performing a final tightening of the first fastening portion after the coupling step.

A co-axial co-current contactor (CA-CCC) is described herein. The CA-CCC includes an outer annular support ring and an inner annular support ring configured to maintain the CA-CCC within an outer pipe and an inner pipe, respectively. The CA-CCC includes rich liquid flow channels located between the outer annular support ring and the inner annular support ring that are configured to allow a rich liquid stream to flow through the CA-CCC, and a central gas entry cone and gas flow channels configured to allow a gas stream to flow through the CA-CCC. The CA-CCC further includes radial blades configured to secure the central gas entry cone to the inner annular support ring and allow a lean liquid stream to flow into the central gas entry cone and the gas flow channels. The CA-CCC provides for efficient incorporation of liquid droplets formed from the lean liquid stream into the gas stream.

There is provided an exhaust gas processing apparatus configured to cause a processing gas to be exposed to or come into contact with a liquid and thereby detoxify the processing gas. The exhaust gas processing apparatus comprises a suction casing provided with an inlet which the processing gas is sucked into and with an outlet which the processing gas is flowed out from; a liquid tank configured to receive an outlet-side part of the suction casing and store the liquid therein; and one or multiple spray nozzles placed in the liquid tank. The outlet of the suction casing is arranged to be located above a liquid surface of the liquid stored in the liquid tank. The one or multiple spray nozzles are configured to spray the liquid from around the outlet of the suction casing to a peripheral part of the outlet.

The present invention relates to a vertical column apparatus (1) for mass exchange processes in the chemical, oil or gas industry and in particular, for the production of iodine from formation water of oil and gas fields, comprising: a gas outlet (2) at the top and a liquid outlet (3) at the bottom of the column (1); a packed section (4) between the top and the bottom of the column (1), wherein the column (1) has a liquid inlet (5) above the packed section (4) and a gas inlet (6) below the packed section (4), wherein an upper portion (7) of the column (1) has a larger diameter (d.sub.u) compared to a diameter (d.sub.p) of the packed section (4).

Disclosed herein is a rotating packed bed, RPB, for mass transfer between a sorbent and a gas, the RPB comprising: a central chamber arranged to receive a flow of a sorbent that is a liquid; and a flow path for the sorbent between the central chamber and a region for mass transfer between a gas and the sorbent; wherein, in use, the flow of sorbent through the region for mass transfer is substantially in cross-flow with the flow of gas through the region for mass transfer. Advantageously, mass transfer between a liquid sorbent and a gas is improved.
