Abstract:
An apparatus and a method for evaporating liquids containing potentially explosive impurities of lower volatility than the actual liquid compound. The set-up of the evaporator allows its operation with complete evaporation of a liquid without formation of a liquid sump of not yet evaporated liquid.
Abstract:
An insert (10) is configured to be inserted into a heat exchanger (500) having a plurality of tubes (600). The insert (10) includes a base (12) and multiple blades (20). The blades (20) are extended from the base (12). At least one of the blades (20) has a spring portion (24). The spring portion (24) is resiliently deformable and configured to be resiliently inserted between two of the tubes (600).
Abstract:
A fluidized bed heat exchanger with a chamber (24) comprises a solid particles inlet port (22), a solid particles outlet port (30), arranged at a distance to the inlet port (22), means (46) for introducing a fluidizing gas from a bottom area into the chamber (24). The heat exchanger further comprises at least two heat transfer means (28) within the one chamber (24), each being provided with a heat transfer medium inlet port (42) and a heat transfer medium outlet port (44), wherein a first heat transfer means (28) is designed as a reheater and second heat transfer means (28) is designed as a superheater to achieve a heat transfer medium temperature and a heat transfer medium pressure above that of the reheater. At least one of the reheater or superheater is made of a multiplicity of heat transfer tubes arranged in a meandering fashion for conveying a heat transfer medium.
Abstract:
A heat exchanger (1, 1A, 1B, 1C, 1D, 1E, 1F, 101, 201, 201A, 201B, 201C, 301, 401, 401 ', 501, 501 ', 601, 701, 701 ') includes a shell (10), a refrigerant distribution assembly (20, 420), a heat transferring unit (30, 30A, 30B, 30C, 30D, 30E, 30F, 230, 230A, 230B, 230C, 330, 430, 530, 630, 730) and a canopy member (452). The refrigerant distribution assembly (20, 420) receives a refrigerant that enters the shell ( 10) and discharges the refrigerant. The refrigerant distribution assembly (20, 420) has at least one outermost lateral end. The heat transferring unit (30, 30A, 30B, 30C, 30D, 30E, 30F, 230, 230A, 230B, 230C, 330, 430, 530, 630, 730) is disposed below the refrigerant distribution assembly (20, 420) so that the refrigerant discharged from the refrigerant distribution assembly (20, 420) is supplied to the heat transferring unit (30, 30A, 30B, 30C, 30D, 30E, 30F, 230, 230A, 230B, 230C, 330, 430, 530, 630, 730). The heat transferring unit (30, 30A, 30B, 30C, 30D, 30E, 30F, 230, 230A, 230B, 230C, 330, 430, 530, 630, 730) includes a plurality heat transfer tubes (31). The canopy member (452) includes at least one lateral side portion (482) extending laterally outwardly and downwardly from a position above the refrigerant distribution assembly (20, 420). The lateral side (482) portion has a free end disposed laterally further from a vertical plane (V) than the refrigerant distribution assembly (20), 420), and lower than an upper edge of the outermost lateral end of the refrigerant distribution assembly (20, 420).
