  • Patent number: 10633331
    Abstract: Disclosed is a process for the preparation of a urea product suitable for being diluted with water so as to form an aqueous urea comprising solution for use in a unit for the reduction of NOx in combustion engine exhaust gases, also known as Diesel Exhaust Fluid (DEF) or to be used in De NOx systems of exhaust vapor from industrial furnaces. The process comprises obtaining an aqueous urea solution from or after a recovery section in a urea production process. This solution, which has a low content of impurities, is subjected to flash crystallization at a low pressure, so as to obtain a solid crystallized urea containing product, which is a free-flowing powder containing less than 0.2 wt. % water. This product is packaged under conditions such that the water content in the packaged product is maintained below 0.2 wt. %. The invention can also be used in a method of increasing the capacity of an existing urea plant.

  • Publication number: 20150044621
    Abstract: In a substrate treatment process, substrates are moved by a transporting device in a transporting direction through a substrate treatment installation having a number of chambers. The substrates are moved by transporting sections of the transporting device driven independently of one another. The transporting sections are driven such that, if substrates dwell temporarily in the transporting section, they are moved back and forth. Stresses in a substrate brought about by differing inputs of heat as a result of both process-induced and malfunction-induced dwell times of the substrate in a chamber are reduced by compensating within the chamber for a structurally brought about input of heat into the substrate, varying periodically over the length of the chamber, during temporary dwelling of the substrate in the chamber by moving the substrate back and forth over at least one period of the heat input by a change of the transporting direction.

  • Patent number: 8506291
    Abstract: A modular mobile furnace train apparatus and a process is disclosed. Mobile furnaces may be interconnected in series to form a modular mobile furnace train. Exhaust gas may then flow through mobile furnaces in a furnace train, allowing for more effective heat transfer to payload being heated as well as increasing energy recapture. Volatile gasses emitted by the payload may be combusted. This recapture reduces production of carbon dioxide and reduces the amount of energy required during the firing while the combustion of volatiles reduces exhaust pollutants. A fire line is an area where heat is applied, while a service line is an area where loading, unloading, inspection, and ongoing maintenance may take place. The modular mobile furnace train allows separation of the fire and maintenance which reduces worker exposure to dangerous environments while decreasing operational costs. Furthermore, the modular mobile furnace facility is less costly to build and operate.

The indirect heating system includes an oxidizer, an all-ceramic, indirect, air-to-air heat exchanger, and one or more metal heat exchangers. The oxidizer can be fired with oil, coal, natural gas or other means, is impervious to attack from dirty fuels, and produces clean hot air for productive use. The movable fluid bed includes a permeable silicon carbide ceramic plate that resides within, and is supported by, a sagger or tray. The sagger is transported on rollers through the plural heating modules, and thus different temperature zones within a furnace as required by the temperature profile of the material being calcined.

  • Publication number: 20120295209
    Abstract: The present invention relates to a method for heating glass sheets having an organic material-based coating in an oven, particularly with a view to the subsequent tempering thereof. More precisely, the invention relates to a method enabling glass sheets having an organic material-based coating to be heat treated by enabling the management of the rapid and violent combustion of said organic material in the oven, using a forced heat convection effect due to a hot gas comprising an oxidizer, injected above the glass sheet at least between t1 and t2, t1 being the time at which the flames from the combustion of the organic matter appear and t2 the time when said flames disappear.

  • Publication number: 20120077135
    Abstract: A method for recycling glass mat waste, wound rovings, and other products includes providing a source of glass mat, or a plurality of rovings, for example on a roll, and routing the glass mat or rovings into a submerged combustion melter. An unwind system and a pair of powered nip rolls, powered conveyors, or other arrangement may work in combination to provide a substantially consistent rate of material into the melter. The melter may operate under less than atmospheric pressure to avoid fumes escaping the melter. A slot in the melter allows ingress of the glass mat or rovings into the melter, and a glass mat former such as a folder may be used to ensure that the mat fits through the slot. Alternatively, the glass mat may be cut by a slitter prior to entering the slot.

    Abstract: Energy absorbing webbings that are generally flat and that have a controllable elongation distance are provided. The webbings are comprised of elongation yarns, such as partially oriented yarns (POY), and ground yarns. In certain embodiments, because they are generally flat, the energy absorbing webbings are suitable for use in retractors. Also provided are processes of manufacturing generally flat, energy absorbing webbings. In certain embodiments, the webbings are subjected to heat using first and second set of rollers with various feed ratios.

    Abstract: Disclosed herein is method for use in a vertical heat treatment system which has an opening which is formed in a partition wall separating a housing-box transfer area from a treating-object transfer area (a wafer transfer area), and and through which an object to be treated is carried in the vertical heat treatment system to carry out a predetermined treatment. When the object to be treated is carried in via the opening of the partition wall, which separates the housing-box transfer area from the treating-object transfer area (wafer transfer area), to carry out a predetermined treatment, the structure of various mechanisms in the vicinity of the opening is simplified, and the space is saved.

  • Publication number: 20100255437
    Abstract: A modular mobile furnace train apparatus and a process is disclosed. Mobile furnaces may be interconnected in series to form a modular mobile furnace train. Exhaust gas may then flow through mobile furnaces in a furnace train, allowing for more effective heat transfer to payload being heated as well as increasing energy recapture. Volatile gasses emitted by the payload may be combusted. This recapture reduces production of carbon dioxide and reduces the amount of energy required during the firing while the combustion of volatiles reduces exhaust pollutants. A fire line is an area where heat is applied, while a service line is an area where loading, unloading, inspection, and ongoing maintenance may take place. The modular mobile furnace train allows separation of the fire and maintenance which reduces worker exposure to dangerous environments while decreasing operational costs. Furthermore, the modular mobile furnace facility is less costly to build and operate.

  • Patent number: 7636992
    Abstract: In a continuous-feed thermomolding machine a foil is advanced in a transport direction at a constant travel speed through a heat station where it is exposed to a heat source such that each piece of the foil is exposed for a predetermined residence time. When the machine is stopped, a shield is positioned in the station between the foil and the source so that substantially no heat is imparted to the foil from the source. The machine is started by accelerating the foil to the travel speed while simultaneously and synchronously accelerating the shield opposite to the travel direction such that, as the shield fully retracts from the station, the foil reaches the travel speed and, before the shield has fully retracted from the station, every piece of the foil in the station exposed by the retracting shield is exposed to the source for the residence time.
