Carrier element, biological water treatment system and their use, and method for biologically treating waste water

Номер: US20120055870A1
Автор: Mikko Siivonen, Petri Pajuniemi
Принадлежит: Individual

The invention relates to a carrier element for an aerobic biological water treatment system. The carrier element has a first end and a second end at a distance from each other, the maximum diameter of the first end being larger than the maximum diameter of the second end. It also has biofilm growing surface structures that extend from the first end to the second end and from inner part of the element towards periphery of the element and at least two support structures that encircle the growing surface structures at the periphery of the element and connect the growing surface structures to each other. The support structures define the outer boundary surface of the carrier element, whereby the support structures are spaced from each other so that apertures allowing access to the biofilm growing surface structures are formed between the support structures. The invention relates also to a water treatment system employing the carrier elements.

Two side intersection lines between the fan-shaped portion and packing sheet is symmetrical with respect to a central folding line which divides the fan-shaped portion into a left part and a right part. The two side intersection lines intercept to each other with an angel of about 10°-170°. When in the operating state where the diversion window and packing sheet are partially folded towards opposite directions, the fluid at the trough flows to a crest of the other side of the packing sheet with the help of diversion windows, thus increasing the area of vapor-liquid mass transfer. Additionally, when liquid goes across the diversion window, liquid at the bottom of the layer flow becomes the liquid on the liquid film, hence effectively facilitating update of the liquid film and turbulence, increasing mixture between the liquid and vapor, and improving rate of the mass transfer between vapor and liquid. 1.

Provided is an NMP recovery system 1 for causing NMP-containing gas to contact NMP-absorbing water, including: fillers ( 10 A) to ( 10 D) 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 ( 10 A) to ( 10 D); and a water distribution unit ( 40 ) for distributing the water so as to make the water permeate through the fillers ( 10 A) to ( 10 D). In the fillers ( 10 A) to ( 10 D), 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.

High aspect ratio catalytic reactor and catalyst inserts therefor

Номер: US20170183228A1
Автор: Jiefeng Lin, Sean M. Kelly
Принадлежит: Praxair Technology Inc

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.
