Methods and systems for the dehydrogenation of hydrocarbons include a direct contact condenser to remove compounds from an offgas process stream. The reduction of compounds can decrease duty on the offgas compressor by removing steam and aromatics from the offgas. The dehydrogenation reaction system can be applicable for reactions such as the dehydrogenation of ethylbenzene to produce styrene, the dehydrogenation of isoamiline to produce isoprene, or the dehydrogenation of n-pentene to produce piperylene.

A method for separating a dissolved product from a liquid is disclosed. A carrier liquid is cooled in a direct-contact exchanger, the direct-contact exchanger using a liquid coolant to cool the carrier liquid. The carrier liquid comprises a dissolved product. The carrier liquid and the liquid coolant are substantially immiscible. A portion of the dissolved product is condensed, frozen, deposited, desublimated, or a combination thereof out of the carrier liquid as a solid product at a liquid-liquid interface between the liquid coolant and the carrier liquid. The solid product is entrained in the carrier liquid, the liquid coolant, or a combination thereof. The solid product is separated from the carrier liquid, the liquid coolant, or a combination thereof.

A heating, ventilating, and air conditioning (HVAC) system has a steerable outlet for directing a stream of treated air into a passenger compartment of a vehicle. A thermographic imager is configured to capture thermographic images covering a fixed region within the passenger compartment in which an occupant is potentially located. The HVAC control circuit is configured to a) compress a thermographic image to a temperature map representing pixels of the thermographic image falling within a predetermined temperature range corresponding to the occupant, b) filter the temperature map according to a sliding window to coalesce continuous regions of pixels on average falling within the predetermined temperature range, c) quantify an area for each continuous region, d) locate a centroid of a continuous region having a largest area, and e) aim the steerable outlet toward the centroid.

A module for a thermal power plant for condensing expelled vapors and cooling turbine effluent from the drained turbine includes a first unit designed to condense expelled vapors as well as a second unit designed to cool the turbine effluent, condensate from the first unit being transferable to the second unit.

Provided is a separator including: a first header into which gas flows from an exterior of the separator; a core connected to the first header and including at least one flow path configured to cool the gas flowing from the first header through the flow path; and a second header connected to the core and configured to guide the gas passing through the at least one flow path to the exterior of the separator, wherein the second header includes at least one first baffle provided on an inner wall of the second header and configured to remove moisture from the gas.

A heat exchanger of flooded type, having: a primary tube bundle, inside which a first hot operating fluid to be cooled down flows; a skirt, circumscribed to the primary tube bundle, which receives a second cold operation fluid which laps against the primary tube bundle in order to subtract heat to the first operating fluid, which second operating fluid flows inside the skirt along to a vertical longitudinal direction orthogonal to the development of the tubes of the primary tube bundle, and wherein the skirt has a prevalent development dimension (L) along the flow longitudinal direction of the second operating fluid; and nozzles for delivering the secondary operating fluid inside the skirt,
wherein an alternative configuration is provided using only the second operating fluid flooding the skirt by entering from a side inlet, without the presence of the above-mentioned nozzles, and an additional configuration using only the nozzles but not such side inlet.

A steam power plant with a low-pressure turbine is suggested with a second low-pressure turbine on a separated shaft line including a separate generator. The second low-pressure turbine is connected to an additional condensing system without cooling water consumption, thus allowing to maintain the power output at a high level, even if the main condensing system has a reduced capacity due to cooling water restrictions.
