A multi-tubular reactor system for catalytically reacting a fluid reactant mixture to form a fluid product comprising a shell and a plurality of reactor tubes housed therein. The reactor system is adapted to allow heat-exchange fluid to flow between the shell and the external surface of the reactor tubes. A reactor tube comprises a reaction zone, and also a heating zone and/or a cooling zone. The reaction zone is positioned downstream of the heating zone. The cooling zone is positioned downstream of the reaction zone. The reactor tube contains a bed of solid particulate catalyst in the reaction zone. The reactor tube additionally contains a heat-exchanging essentially rod-shaped insert having a length of from 1 to 20%, preferably 1 to 5%, of the total length of the reactor tube in the heating zone and/or the cooling zone.

Rod-shaped inserts in reactor tubes

The invention relates to a process for remediation of a fluid contaminated with alkylene oxide, involving contacting the contaminated fluid with an aqueous absorbent to yield a fat absorbent having absorbed fluid, conferring intimate contact of fat absorbent and alkylene oxide and conversion of alkylene oxide; and, an apparatus for remediation of the fluid which has a converter having inlet means connected to the outlet of a fluid absorber for contacting fluid and aqueous absorbent, a holding unit having a volume V for the fat absorbent, and outlet means connected to the inlet of a fluid desorber.

Remediation process and apparatus

A process for catalytically reacting a fluid reactant mixture in a multi-tubular reactor system to form a fluid product, whereby the reactant mixture is led through at least one reactor tube containing a fixed bed of solid particulate catalyst and surrounded by a heat-exchange fluid, and whereby an upstream portion of the reactor tube is dedicated to pre-heating the reactant mixture and/or a downstream portion of the reactor tube is dedicated to post-cooling the product, characterized in that the upstream portion and/or downstream portion of the reactor tube contains a heat-exchanging essentially rod-shaped insert, the insert having a length of from 1 to 20%, preferably 1 to 5%, of the total length of the reactor tube.
