Provided is a catalyst article for simultaneously remediating the nitrogen oxides (NOx), particulate matter, and gaseous hydrocarbons present in diesel engine exhaust streams. The catalyst article has a soot filter coated with a material effective in the Selective Catalytic Reduction (SCR) of NOx by a reductant, e.g., ammonia.

Processes and plants for the production of purified urea solution are described. In a described urea production process, urea is produced in a synthesis section without a high pressure stripper and the urea solution is subjected to purification after the recovery section, to give purified urea solution and off-gas. The purification comprises e.g. steam stripping.

A hybrid system for freshwater production utilizing the latent heat of condensation of atmospheric air humidity as a source of thermal energy to evaporate freshwater in a brine or saline and delivered to the saline evaporating chamber by a heat pump. Distillates form on both sides of the heat transfer, and intensification of humidity condensation in the air leads to the intensification of saline evaporation contributing to the overall increased yield of freshwater. The process is optimized by integrated systems in which the waste heat of inside and outside sources and the heat sink effect of the saline feed amplify the COP and SEER indexes of the installation. The technological regimes in which the equipment is used are intensified and optimized, cutting the desalination costs to the ranges affordable to the general population residing in arid regions in need of such technology.

The invention relates to a process for the recovery and recycling of ethylene oxide (EO) after use in a sterilization process. The process involves the steps of introducing a mixed gas stream containing EO, nitrogen, oxygen, CO.sub.2, water, and a few other trace elements. The system includes integrated EO concentration sensors to determine the concentration of the EO in the gas stream. The system includes a series of compressors to pressurize the gas stream, and chillers or condensers to cool the gas stream to condense the EO out of the gas stream. The system includes temperature and pressure sensors to determine the conditions in the gas stream, and a control system that evaluates the temperature and pressure data and controls the compressors and chillers to achieve the properties to maximize the condensation of EO out of the gas stream.

A system and method for continuous ethanol recovery from high solids corn slurry mash fermentation in an ethanol plant.

System, apparatuses, and methods for processing feedstock have a decomposing stage for breaking down feedstock into liquid and gaseous products and a condensing stage for condensing gaseous products to a liquid condensate. A mixing stage can also be used to combine gaseous and liquid feedstock portions into a combined liquid feedstock to be fed to the decomposing stage. The decomposing stage can be one or more flux tanks having a field generator for creating an electromagnetic field through the flux tank configured to decompose feedstock inside. The condensing stage can have a catalyst tank, distillation tank, condensing pipes, or a combination thereof. The mixing stage can be a reformer device having pairs of plates, at least some of the plates are capable of rotating to generate a shear force that creates a cavitation effect to combine the gaseous and liquid feedstock portions.

The present invention relates to a process (100) for separatory processing of a starting mixture containing predominantly hydrogen, methane and hydrocarbons having two or two or more carbon atoms, wherein at least a portion of the starting mixture is cooled to form one or more condensates using one or more heat exchangers (101, 103, 105, 107) and at least a portion of the condensate(s) is subjected to a rectification to form a gaseous methane-rich fraction. It is provided that the gaseous methane-rich fraction is used to form a first fluid stream which is at least partly compressed, in an unchanged composition with respect to the gaseous methane-rich fraction, to a liquefaction pressure level of 35 to 45 bar, and at least partly liquefied by cooling, and in that the first fluid stream, or a second fluid stream formed using the first fluid stream, is expanded to a delivery pressure and heated in the or at least one of the heat exchanger(s) (101, 103, 105, 107). A corresponding plant likewise forms part of the subject matter of the invention.
