Method for reducing vibrations in a conduit in which gas-liquid flows by enlargement of part of conduit by provision of insert

摘要

Disclosed is a method for reducing vibrations in a conduit through which a gas-liquid mixture flows with a flow rate up to 25 m/s, the conduit having a certain wetted surface area, in which method the wetted surface area of at least part of the conduit is enlarged at least 2 times, preferably at least 6 times, more preferably at least 12 times, by providing the conduit over at least part of its length with an insert. The invention further relates to a vertical feed supply conduit, debouching into the feed inlet of a gas-liquid contact column, the gas-liquid contact column comprising a gas outlet, a liquid outlet and a feed inlet, wherein the vertical feed conduit comprises a vibration reducing insert, by which insert the wetted surface area of the conduit is enlarged as above described.
