Abstract: A semi-continuous deodorizer providing a first main vessel, and a second vessel, wherein the second vessel is connected to the first main vessel by a duct for the transport of gases and vapors, the second vessel being connected to a vacuum system, wherein both the first main vessel and the second vessel are made of stainless steel and built hermetically.

Abstract: The degassing apparatus removes liquid from a vacuum tank (1) with a suction pump (6) and supplies that liquid to a storage tank (9), sprays storage tank liquid into the vacuum tank through a convergent nozzle (7), removes gas from liquid in a state of reduced pressure inside the vacuum tank, and stores the degassed liquid in the storage tank. The storage tank is an airtight hermetically sealed tank provided with a reduced pressure retaining valve that discharges gas accumulated inside the storage tank.

Abstract: A system and method recover water from an ambient airstream. Dehumidification of the airstream is also achieved by removal of the water. A device of the system includes a chamber having a group of trays that hold respective amounts of liquid desiccant in each tray. A foam media absorbs the desiccant to increase an exposed surface of the desiccant to the airstream. Fans and valves are used to control airflow through the device. A charge cycle circulates air through the device to remove water vapor from the airstream. A subsequent extraction cycle removes water collected in the liquid desiccant by a condenser communicating with the chamber. An integral heat exchanger adds heat to the chamber during the extraction cycle. A controller is used to integrate and manage all system functions and input variables to achieve a high efficiency of operational energy use for water collection.

Abstract: A vacuum vessel for continuous or semi-continuous treatment of oils in connection with deodorization comprises spaces (12, 121, 122) through which oil to be treated is brought to pass and means to heat or cool the oil in the form of U-tubes. There are perforated pipes (26) arranged at the bottom of said spaces to lead stripping gas into said oil. The vessel has a connection to a vacuum source (7). The spaces in the vessel are arranged such that the oil to be treated in the vessel flows through the same by gravity. The heating or cooling medium passing the U-tubes is arranged to be pumped therethrough. The U-tubes for heating or cooling medium are arranged in such a way in said spaces that the flow of oil is counter-current to the flow of heating or cooling medium all through the vessel and a number of U-tubes are arranged in groups (13), parallel and in rows above each other in said spaces.

Abstract: The present invention relates to a pressure swing adsorption process, also known as PSA process, which is modified with a view to utilizing the heat from the post-adsorption stream coming from the molecular sieves to heat/vaporize the pre-adsorption stream containing the hydrated product or the mixture component(s) to be adsorbed in said sieves. The present invention provides alternative arrangements for the heat exchanger system in order to use the thermal potential of the post-adsorption stream with the elimination or minimization of the risk of a slug flow regime in the exchangers, the so-called “gush,” which would be a natural result from the periodic oscillation characteristic of PSA processes. With this, the vapor consumption with the modified process according to the present invention is considerably reduced.

Abstract: A waste liquid treatment system includes a heat retaining/storage tank section adapted to store waste liquid, retaining the temperature thereof, an atomization chamber section capable of gasifying waste liquid by atomization and/or thermal vaporization, a heating/decomposition chamber section whose internal temperature is held in a thermal decomposition temperature range good for thermally decomposing harmful chemical substances contained in the mist and/or vapor gas of waste liquid when the mist and/or vapor gas of waste liquid passes through the inside thereof, a rapid cooling section for rapidly cooling decomposed exhaust gas and a vacuum pump section for drawing mist and/or vapor gas of waste liquid.

Abstract: A vacuum vessel for continuous or semicontinuous treatment of fatty oils in connection with deodorization includes spaces through which the oil which is to be treated is brought to pass. The vessel also contains U-tubes used to heat or cool the oil and perforated pipes arranged at the bottom of the vessel. Through these pipes stripping gas is led into the oil. The vacuum vessel is connected to a vacuum source. According to the invention the vessel has the form of a container with a mainly rectangular bottom with partitions parallel to a long side of the container. These partitions delimit channels connected in series through which the oil passes. The bottom of a first channel as seen in the direction of flow is arranged on a higher level than the second channel seen in the direction of flow such that the oil is forced to pass through the vessel by gravity. The vacuum vessel has a low height in relation to the length of its sides.

Abstract: The device serves for mixing and degassing a free-flowing compound (5), in particular a casting resin containing filler. The device has an evacuable container (1, 6) of cylindrical design, the container axis (2) of which is aligned essentially in the vertical direction. Provided in the interior of the container is a rotatable plate (13), fastened on an axially guided shaft (12), for distributing compound (5) fed into the container (1, 6), as well as a thin-layer degassing system (14) which can be heated and cooled and degasses the compound (5) fed by the distributing plate (13). A stirrer homogenizes the degassed compound collected in the interior of the container. The thin-layer degassing system (14) occupies the major part of the space present between the shaft (12) and the wall of the container (1, 6).

Abstract: A method and apparatus for treatment of contaminated water, containing undesired solid, liquid, and/or gaseous materials includes an electro-floculation means for disassociating ions from the undesired solid material and from the contaminated water, and further includes a separation tower having various deflection means deflecting undesired solid materials downwardly through to the separation tower.

Abstract: A melt is converted into pieces by being converted to individual quantities that are dropped onto a cooling surface. Disposed above the cooling surface is a hood having a suction outlet for conducting waste air to a cleaner. Disposed in the hood upstream of the suction outlet is an arrangement of surfaces defining a serpentine flow path for the waste air so that a vaporous component of the waste air crystallizes on the surfaces. The surfaces are formed by plates mounted on a common transport carrier which periodically moves the plates against a scraper for scraping off the crystallized material. Alternately, the surfaces can be defined by endless belts which move against scrapers.

Abstract: A combined vertical column and shallow tray semicontinuous deodoriser for edible oils and fats and comprising a column (10) of discrete vessels and a deodorising vessel (13) disposed within or valve-connective thereto. In the operation of the device, heated oil from a vessel (12) is supplied to deodorising vessel (13) wherein it is circulated by steam injection at (33) through a lift tube (29), between a plurality of vertically separated self draining shallow trays (26, 27, 28). The entire oil content of deodorising vessel (13) is circulated therethrough approximately once a minute for a period in the region of eighteen minutes to strip free fatty acids and other volatile components from the oil by falling curtain and steam sparge techniques, and then the oil batch is discharged to a heat recovery vessel (14) and a cooling vessel (15) before product discharge.

Abstract: A device and a method for the continuous degassing of casting resin comprising a housing (1) which has an inlet (2) and an outlet (3) for passage of the casting resin and is connected to a vacuum source (4). In order to achieve with a compact design of the housing a complete continuous degassing of the casting resin material, several separate but spatially connected areas (5) are provided in the housing (1), through which areas the casting resin is sequentially guided.
