A scrubber for cleaning of a gas comprises a casing enclosing a scrubbing chamber. The casing comprises a gas inlet into and a gas outlet out from the scrubbing chamber. A gas flow of the gas flows through the scrubbing chamber in a flow direction from the gas inlet to the gas outlet. A deflector device is provided in the scrubbing chamber between the gas inlet and the gas outlet and forms a passage between the deflector device and the casing. A spraying nozzle is arranged between the gas outlet and the deflector device for spraying a scrubbing liquid into the scrubbing chamber and the gas flow. An inner shield extends between the casing and the deflector device, surrounds the deflector device at least partly, and forms a gap with the casing. Scrubbing liquid may flow through the gap.

The present invention relates to a method for the production of polyamide 6 with low extract content and a device for it. Here, a melt of non-extracted polyamide 6 is cleaned from monomer and oligomers in a degasification device in vacuum, wherein the vapor being withdrawn from the degasification device by the vacuum generation device is cleaned from monomer, oligomers and optionally water at first in a direct condenser which is operated with liquid -caprolactam and subsequently in a pre-separator which is cooled with a coolant, before it reaches the vacuum generation device. A particularly preferable variant of the method envisages the usage of the melt of polyamide 6 with low extract content so prepared in a direct process of spinning into textile fibers and/or filaments.

A gas-water separation system may be used for removing water from a wet gas compressed in a water-injected contact-cooled gas compressor. The gas-water separation system may include a tank constructed to hold a quantity of water; a heat exchanger coupled to the tank and constructed to extract heat from the water to chill the water when the water is present within the tank; an inlet port constructed to inject a flow of the wet gas into the chilled water when the water is present within the tank, the chilled water being operative to condense water vapor from the wet gas and reduce the dew point of the wet gas to yield a chilled compressed gas; a biological control system constructed to suppress biological activity in the tank; and a discharge port operative to discharge the chilled compressed gas.

The invention relates to an apparatus for separating a condensable reaction product from a process gas mixture. The apparatus includes a pressure jacket having an interior, wherein two process units are arranged one atop the other in the pressure jacket. The upper first process unit is configured for condensing the liquid reaction product from the process gas mixture and is thus in the form of a plate heat exchanger. The plate heat exchanger includes vertically arranged plates traversable by a cooling medium. The plates have plate interiors which are traversable by the cooling medium. Adjacent plates spaced apart from one another define plate interspaces which are traversable by the process gas mixture. The lower second process unit is configured for separating the reaction product condensed in the first process unit and is thus in the form of a gas-liquid separator.

A Pressure Gradient Seawater Distillation System for distilling a fluid. The elements of the system are positioned to transmit heat to improve efficiency. Fluid enters an entry tube, cooling a photovoltaic panel and cooling water in an intermediate tube. The entry tube deposits fluid in an evaporator, where the fluid is heated to transform into a gas. The gas is transmitted to a condensing chamber, where the pressure is varied to assist in condensation. Condensed water is stored in a reservoir, where a splitter is used to transmit a portion of the excess water to an exit point, while the remainder of the water is cooled by heat exchange and transmitted to a nozzle in the condensing chamber. Water falls from the nozzle to capture water vapor in condensing the gas in the condensing chamber or in condensing regions of a single compartment distiller. A flow control element, a pressure valve, and pressure controls are included for managing fluid flow and pressure.

A method is described for reducing contrails during operation of an aircraft (100, 100) having a heat engine 10. The method includes inducing a condensation of moisture contained in the exhaust gas (A) of the heat engine by mixing at least a portion of the exhaust gas with ambient air (U) of the aircraft as well as separating the condensed-out water on the aircraft. Also described is an aircraft (100, 100) having a heat engine (10). The aircraft includes at least one nozzle (30) which is adapted for conducting exhaust gas (A) from the heat engine of the aircraft at least partially into ambient air (U) of the aircraft and thus to produce a gas mixture, and at least one separator device (40) for separating condensed-out water from the gas mixture.

A method for removing moisture from moist air in an appliance, such as a treating chamber of a dishwasher, wherein a drying system includes a condensing system and heat exchange systems that enhance condensation with both ambient air and cold water. Optionally, the method can also include a charge or charges of warm, ambient air or ambient air with moist air during recirculation of moist air.

One exemplary embodiment can be a process for cooling a vent stream from a receiver. Generally, the process may include providing a refrigerant including at least one compound contained in the receiver so the refrigerant leaking into the receiver can be compatible with the process.

A distillation system receives a feed solution to produce residue and distillate. A heat pump includes parts of a first and second heat exchangers, a working fluid, a working fluid compressor, and an expansion device. The working fluid receives available heat energy from the distillate in the second heat exchanger, receives at least some additional heat energy in the working fluid compressor, and releases at least some of that heat energy into the feed solution in the first heat exchanger. The first heat exchanger receives the feed solution, permitting transfer of at least some heat energy into it. A separator receives the feed solution from the first heat exchanger and separates it into the residue and distillate. The second heat exchanger receives the distillate, permitting transfer of at least some heat energy back into the working fluid. And a distillate extractor directs the distillate out of the second heat exchanger.

The present invention relates to a process and device for condensing a first fluid rich in carbon dioxide using a second fluid.
