A dephlegmation condenser for binary/polynary condensation of a vapor mixture is arranged upright. It has tubes (4) through which the coolant flows, an inlet connection (1) arranged in the top region of the coolant tubes and intended for the mixture to be condensed, and a collecting space (2) arranged below the coolant tubes (4) and intended for the condensate to be drawn off. The inlet connection (1) and the collecting space (2) are connected to one another via a condenser shell (3) encasing the tubes (4). The coolant is directed in pure counterflow to the mixture in the predominant part of the condensation space.The vapor-side, smooth temperature profile achieved is a consequence of the segregation during the condensation. A mixture which is enriched with the higher-boiling component of the mixture condenses at the start of the condensation section, whereas another mixture which is enriched with the lower-boiling component of the mixture condenses out at the end of the condensation section.

A direct contact condenser is arranged to establish sequential steam flows of downward, lateral, and tortuous but collectively upward directions in a housing. Cooling liquid fed to the condenser is introduced to first overflow means for temporarily accumulating cooling liquid and for allowing excess accumulated cooling liquid to overflow. Second overflow means is provided for temporarily accumulating the cooling liquid supplied from the first overflow means, for allowing the cooling liquid to fall in multiple streams into the collectively upward steam flow zone to cause direct heat exchange between the falling cooling liquid and the steam, and for causing excess cooling water accumulated by the second overflow means to overflow. The cooling liquid overflowing from the second overflow means is supplied to the downward stream flow to cause direct heat exchange between the cooling liquid and the steam when excess accumulated cooling liquid overflows from the second overflow means.

A vapor condenser for a system and apparatus for condensing and recovering vapors of low volatile liquids such as hydrocarbons has a U-shaped passage therethrough with one end of said U-shaped passage in communication with an inlet for vapors of the low volatile fluids to be condensed and the other end of said U-shaped passage is in communication with a discharge outlet for non-condensible gases, finned coil sections having passages for passing cooling fluid therethrough are disposed in said U-shaped passage, said finned coil sections having the fins thereon more widely spaced adjacent the inlet end of the U-shaped passage and the fins being more closely spaced on the finned section progressively the more remote the finned sections are from the inlet to the U-shaped passage, and the fins on the more closely spaced finned coil sections being lined up with the fins on the widely spaced finned coil section of the U-shaped passage, a collecting chamber at the end of said U-shaped passage remote from the inlet end, and a drain for passing condensate from the vapor condenser.Additionally, a vapor condensing and recovery assembly including the vapor condenser above described, a decanter, and a circulating system for maintaining the collection chamber for the vapor condenser, the outlet passage for the vapor condenser, the inlet passage for the decanter, and a separating chamber in the decanter respectively at temperatures to increase the temperature of the condensate to approximately 60.degree. F to 65.degree. F.
摘要:
The present invention relates to a method for stabilizing the temperature of an instrument which consists in that the instrument whose temperature has to be stabilized, is brought into contact with a container containing a temperature stabilizing element which presents, in the considered temperature range, at least one transformation point, so that the latent heat of transformation, which produces an elevation of the calorific capacity at the time of the passage through the transformation point, stabilizes the temperature of the instrument.
摘要:
A series of controlled gradient condensers for removing gaseous hydrocarbon pollutants from the stack effluent of an industrial treating plant, such as a veneer dryer. The gaseous effluent stream is conducted from the industrial treating plant to a precooler to bring the effluent temperature to the condensation point of the highest boiling pollutant. Thereafter the effluent stream is passed through a successive series of controlled gradient condenser, each operating in a temperature range lower than that of the immediately preceding condenser. The first several condensers are air cooled and designed to remove the higher boiling pollutants. Each air cooled condenser is wrapped with one or more heater coils, the turns of which are not uniformly wound about the condenser tubes but are more widely spaced toward the outlet or cold end of the condenser. Electric power to each heater coil is controlled by a respective power controller responsive to temperature sensors located inside the condenser for measuring a temperature gradient along the path of flow of the effluent. If any measured temperature gradient exceeds a predetermined maximum allowable limit, the power controller adjusts the electric power through the appropriate heater coil to restore the temperature gradient, and thus the cooling rate, to a value below the maximum limit. As long as the predetermined maximum temperature gradient or cooling rate for each gaseous pollutant is not exceeded the formation of aerosol is avoided and substantially all of the pollutant condenses in collectable liquid form on the walls of the condenser, thereby cleansing the effluent. Each condenser has a reservoir which collects the condensed pollutants by gravity feed, while the uncondensed remaining effluent passes to the next succeeding condenser. The last in the series of condensers is water cooled for condensing those pollutants having the lowest boiling points. The temperature gradient in the water cooled condenser is controlled by temperature sensors, similar to those in the air cooled condensers, which modulate the flow of coolant by controlling the power to the coolant pump. The different temperature ranges at which the respective condensers operate are preferably fixed so that the minimum temperature at the outlet of a respective condenser is greater than the highest melting point of any pollutant condensed within that condenser, so as to prevent solidification of the pollutants and fouling of the condensers. Immersion heaters in the condenser reservoirs further aid in preventing solidification. If solidification of one or more pollutants collected in a particular condenser cannot be avoided, scraper paddles are provided to scrape the solid material off the condenser walls for disposal through a solids removal port. The reservoir of the last in the series of condensers, from which the remaining effluent is vented to the atmosphere, includes a reservoir auxiliary cooling system for the purpose of further reducing effluent temperature if necessary to remove any remaining contaminants.

FLUID TO DEPOSIT ADDITIONAL CONDENSATE WITHIN THE FIBROUS MATERIAL.
AN APPARATUS AND METHOD FOR CONDENSING A VAPOR BEING CARRIED BY A GASEOUS FLUID IN WHICH THE FLUID AND VAPOR ARE PASSED THROUGH A THERMALLY CONDUCTIVE SURFACING MATERIAL HAVING A LARGE NUMBER OF APERTURES BUT STILL PRESENTING A LARGE CONDENSING AREA. THE SURFACE IS MAINTAINED AT A TEMPERATURE LOWER THAN THAT OF THE FLUID. A FIBER MAT IS PLACED ON THE DOWNSTEAM SIDE OF THE CONDENSING SURFACE, THE FIBER MAT HAVING BEEN PREVIOUSLY WETTED WITH PURIFIED CONDENSATE, AND THE GASEOUS FLUID BEING IN FULLY SATURATED CONDITION, SUCH THAT UPON HITTING THE CONDENSING SURFACE THE FLUID WILL HAVE ITS TEMPERATURE LOWERED AND CONSEQUENTLY DEPOSIT EXCESS CONDENSATE ON THE SURFACE. THE DEPOSIT OF THE CONDENSATE HAS THE EFFECT OF RAISING THE TEMPERATURE OF THE GASEOUS FLUID TO AND BEYOND ITS INITIAL TEMPERATURE. THIS INCREASE IN TEMPERATURE CAUSES THE FLUID TO BECOME UNSATURATED. THE UNSATURATED FLUID PASSES THROUGH THE APERTURES IN THE CONDENSING SURFACE AND INTO THE FIBROUS MATERIAL, WHERE IT ABSORBS A QUANTITY OF PREVIOUSLY PURIFIED CONDENSATE. THE ABSORPTION OF THE PURIFIED CONDENSATE BY THE FLUID AGAIN LOWERS THE TEMPERATURE BELOW THE TEMPERATURE OF THE FLUID AT THE CONDENSING SURFACE. LOWERING THE TEMPERATURE WILL CAUSE THE GASEOUS
