摘要:
Apparatus and process for removal of volatile degradation products from the absorbent circuit of a CO2 separation process are provided. The CO2 separation process may use the absorbent circuit in an absorption process and a desorption process. Condensate is withdrawn from a condensation process connected downstream of the desorption process, and purified to substantially free such condensate of degradation products. The purified condensate is recycled back to the absorbent circuit.

摘要:
A process for purifying a product contaminated with nitrosamines from an operating plant is proposed. The contaminated product is heated to a temperature T at which the nitrosamines are thermally destroyed. The temperature T is set at a higher level than the maximum temperature in the operating plant, and maintained for a residence time t. An apparatus for regeneration of a nitrosamine-contaminated product from a CO2 capture plant is also proposed.

The invention relates to an anti-slip insert mat having a carrier layer and a textile catching layer formed of filaments/fibers, wherein the catching layer has raised regions and compressed regions of lower height, wherein the raised regions are formed by free ends of the fibers and the compressed regions of the catching layer are formed by permanently pressing the free ends of the fibers.
摘要:
Transistor structures, with one source/drain region connected to a charge storage device to be insulated includes an asymmetric gate conductor structure. At a first side wall, which faces the one source/drain region, the asymmetric gate conductor structure has a side wall oxide with a greater thickness and a bird's beak structure with a greater length than at an opposite, second side wall. An effective channel length is increased for the same feature size of the gate conductor structure. Memory cells can be realized in a higher density.
