Gas-liquid contact device, distillation device, and heat exchange device

Provided is an NMP recovery system 1 for causing NMP-containing gas to contact NMP-absorbing water, including: fillers (10A) to (10D) that are permeable to the water and hold the water, wherein the permeated water moves according to gravity to flow out from the fillers; an NMP-containing gas distribution unit (30) for distributing the NMP-containing gas so as to cause the NMP-containing gas to contact the water held by the fillers (10A) to (10D); and a water distribution unit (40) for distributing the water so as to make the water permeate through the fillers (10A) to (10D). In the fillers (10A) to (10D), the NMP-containing gas is made to contact the NMP-absorbing water. Accordingly, NMP in the NMP-containing gas is absorbed in the water, so that the NMP is separated from the NMP-containing gas.

A tower packing element, a tower packing, a packing tower, and a mixer comprising the tower packing element are provided. The tower packing element are manufactured by a deformed plate and comprises a plurality of strip assemblies arranged along a longitudinal direction of the tower packing element and a connecting plate portion connected between adjacent strip assemblies. Each of the strip assemblies defines a central passage therein, and the central passage is extended in a lateral direction of the tower packing element. The connecting plate portion is extended along the lateral direction of the tower packing element. The adjacent strip assemblies and the connecting plate portion connected therebetween define a side passage parallel to the central passage.

High aspect ratio catalytic reactor and catalyst inserts therefor
09938146 · 2018-04-10 · ·

The present invention relates to high efficient tubular catalytic steam reforming reactor configured from about 0.2 inch to about 2 inch inside diameter high temperature metal alloy tube or pipe and loaded with a plurality of rolled catalyst inserts comprising metallic monoliths. The catalyst insert substrate is formed from a single metal foil without a central supporting structure in the form of a spiral monolith. The single metal foil is treated to have 3-dimensional surface features that provide mechanical support and establish open gas channels between each of the rolled layers. This unique geometry accelerates gas mixing and heat transfer and provides a high catalytic active surface area. The small diameter, high aspect ratio tubular catalytic steam reforming reactors loaded with rolled catalyst inserts can be arranged in a multi-pass non-vertical parallel configuration thermally coupled with a heat source to carry out steam reforming of hydrocarbon-containing feeds. The rolled catalyst inserts are self-supported on the reactor wall and enable efficient heat transfer from the reactor wall to the reactor interior, and lower pressure drop than known particulate catalysts. The heat source can be oxygen transport membrane reactors.

SUB-TEXTURED PACKING FOR GAS SEPARATION
20240375042 · 2024-11-14 ·

A packing for gas separation from a liquid absorbent includes a body having a corrugated surface or surface sub-texture adapted to create local turbulence within a liquid absorbent with which the body has been wetted. The body may also has a corrugated profile wherein the surface sub-texture comprises a plurality of individual scallops and the corrugated profile comprises a plurality of individual furrow with between about 2 and about 50 individual scallops per furrow. The packing is useful in a method for gas separation from a liquid absorbent.
