Abstract:
A sealed observation element for viewing the flow of molten liquid during the operation of a sulfur recovery unit comprises at least one sight glass that is heated and which may be swept with a purge gas supplied through one or more bleed rings to prevent condensation or deposition of materials on the side of the sight glass exposed to the process stream.

Abstract:
According to the invention, a device which has an atomizing container (1) is provided for generating an aerosol comprised of a gaseous constituent, especially of air such as sterile air, and of a liquid constituent, especially of a sterilant such as peroxide. The liquid constituent is continuously atomized in said atomizing container (1), and is mixed into a gas stream passing into the atomizing container (1). To this end, an atomizing nozzle (8) for the liquid constituent of the aerosol is centrally arranged in the lower area of the atomizing container (1), and means (2; 23) for forming an upward-oriented directional gas stream are arranged upstream from the atomizing nozzle (8). Said gas stream flows around the atomizing nozzle (8) in a coaxial manner.
Abstract:
According to the invention, in order to produce an observation window (7) in reaction vessels, autoclaves, boilers, nuclear reactors and the like, a cubically stabilised zirconium oxide monocrystal can be used. Preferably, calcium, magnesium, yttrium or another transparent element of the heavy lanthanoids is used to stabilise zirconium oxide. Due to the excellent transparency of such observation windows (7) produced by means of a cubically stabilised zirconium oxide monocrystal, they are especially suitable for monitoring processes in situ in closed vessels such as the above-mentioned reaction vessels and the like, the processes being monitored either optically by means of photographic appliances or video appliances (1), or by means of spectroscopic methods.
Abstract:
Die Erfindung bezieht sich auf eine Vorrichtung zum Beobachten von Prozeßabläufen, insbesondere von Prozeßabläufen in der Vakuumtechnik mit einem hinter einer Kammer angeordneten Schauglas 3, an dem eine rotierende Vorrichtung zur Verhinderung von Verschmutzung des Schauglases 3 vorbeibewegt wird. Die rotierende Vorrichtung zur Verhinderung von Verschmutzung des Schauglases 3 ist als zylinderförmiger Drehkörper ausgebildet, der auf der einen Seite mit einer Eingangsöffnung 24 und auf der anderen Seite, diametral gegenüber, mit einer Ausgangsöffnung 25 versehen ist.
Abstract:
Es ist eine Vorrichtung zum Beobachten gasdicht und druckfest abgeschlossener Räume von Anlagen von außen offenbart, die einen aus Metall bestehenden zylindrischen Rahmen (2) aufweist, in dem ein durchsichtiger Einsatz (3) angeordnet ist. Der Rahmen (2) besteht aus einem ein geringes Wärmeschrumpf- und dehnungsverhalten aufweisenden Edelstahl und der Einsatz (3) aus einem ein ähnliches oder noch geringeres Wärmeschrumpf- und dehnungsverhalten aufweisenden Glas.
Abstract:
A catalyst loading system comprising: a vessel comprising at least one gas distribution nozzle at or near the bottom of the vessel, a top fluid distributor located at or near the top of the vessel, a catalyst inlet through which catalyst is introduced into the vessel, a first contact point at which catalyst introduced into the vessel first contacts the contents of the vessel, and a discharge outlet whereby catalyst exits the vessel. Methods of preparing catalyst slurry for introduction into a downstream reactor or in-situ activation within the vessel utilizing the catalyst loading system are also disclosed.
