A vertical scrubber (1) for exhaust gas from a marine vessel is described. An exhaust gas tube (2) is substantially coaxially arranged through the bottom of a lower scrubbing chamber (3) and is released though an exhaust gas outlet (20) being coaxially arranged through the top of an upper scrubbing chamber (13). A lower scrubbing chamber deflection body (4) is arranged above the opening of the exhaust gas tube (2) for redirecting the exhaust gas towards the walls of the scrubber and create turbulent gas flow, where one or more lower chamber water injector(s) (6, 6′) is (are) arranged above the lower scrubbing chamber deflection body (4), to introduce scrubbing water, and where a lower chamber exhaust gas outlet (12) is arranged at the top of the lower scrubbing chamber (3) as a coaxial constriction, for withdrawing the partly scrubbed exhaust gas from the first scrubbing chamber and introducing the gas into the upper scrubbing chamber (13).

The invention relates to packed contact devices used in heat/mass exchange column apparatuses in which the processes of rectification, distillation, absorption, and extraction are run, and can be applied in the oil refining, petrochemical, chemical, gas-processing, and food-manufacturing industries. A contact device for carrying out heat/mass exchange and separation of phases in sectional cross-flow packed columns in gas/liquid and liquid/liquid systems comprises a plurality of identical contact elements assembled one upon another in one or more rows in blocks held together by spokes and vertical posts, with formation of walls in the column body that are restricted on horizontal end faces by horizontal segmental baffles conjugated in an arc with the column body; thereat, arranged between the walls are liquid distributors having a perforated part, an additional baffle, deflector plates, and vertical support plates. The space between the lower and upper walls is sealed by means of battens.

The invention relates to method for deacidification of fats and oils comprising: feeding stream (1) to a stripping section; condensing the volatile phase in a high temperature condensing zone, sending the condensed phase to distillation A; distillating the condensed phase, obtaining a volatile stream; passing the volatile stream along with the vapor phase from the condensation zone to a cold condensation zone obtaining a condensate and a stream (4); allowing stream (4) to continue to vacuum system and subjecting the cold condensate to distillation B; and producing a stream of fatty acids (5) and a stream of micronutrients (6).

A method for transfer of heat between a first and a second fluid, wherein the first and the second fluid circulate respectively on both sides of a thermally conductive wall of a monobloc assembly formed in a single piece. The monobloc assembly, which is arranged in the interior of a device, includes: a first, three-dimensional, cellular, thermally conductive structure through which the first fluid can pass; at least the thermally conductive wall; and a second, three-dimensional, cellular, thermally conductive structure through which the second fluid can pass. The first and second three-dimensional, cellular structures are situated on both sides of and integral with the wall such that heat transfer is carried out from the first to the second fluid through the wall, and both first and second fluids are under liquid phases and under gaseous phases, with the liquid phases circulating in a direction opposite that of the gaseous phases.

A vapor distributor for use in an internal region of a mass transfer column to receive and redistribute a vapor stream when it is introduced radially into the internal region through a radial inlet in a shell of the mass transfer column. The vapor distributor includes a plurality of multiple-sided elongated deflectors arranged in a descending array and a pair of braces that extend longitudinally across the array of elongated deflectors and hold them in spaced apart and side-by-side relationship to each other. Each of the elongated deflectors has a deflecting surface that faces toward the radial inlet to redirect and redistribute the radially-introduced vapor stream. The braces each include a strut that may also redirect and redistribute the vapor stream.

Methods, systems, and techniques for desalinating a saltwater using a humidifier unit. The humidifier unit has a housing, which has a carrier gas inlet and a saltwater inlet. The humidifier unit also includes a packing, within the housing, having a surface with a critical surface tension of less than 25 mN/m according to the Zisman method. The packing is arranged to facilitate a saltwater that enters the housing through the saltwater inlet and a carrier gas that enters the housing through the carrier gas inlet to contact each other. The contact facilitates evaporation of the saltwater, which produces salt solids on at least a surface of the packing, a humidified gas and a concentrated brine.
