A water treatment tank includes: a tank body including a bottom surface extending in a horizontal direction; an overflow wall partitioning the inside of the tank body into an upstream tank into which treatment water having absorbed sulfur from an exhaust gas is introduced and a downstream tank into which the treatment water overflowing from the upstream tank is introduced to flow therein; and an inclined part that is provided between the bottom surface of the tank body and the overflow wall in the downstream tank and is inclined downward as it goes from the overflow wall toward a downstream side inside the downstream tank to be connected to the bottom surface of the tank body.

Various embodiments of a portable carbon dioxide (CO2) absorption device that may remove excess CO2 from a closed environment are disclosed herein. The absorption device is reusable and configured for many environments.

A still/stahl column includes a still section, a primary stahl section, the primary stahl section positioned beneath the still section, and a polishing stahl section, the polishing stahl section positioned beneath the primary stahl section. A process also includes feeding a water rich glycol still feed stream to the still section and feeding a stripping gas feed stream to the polishing still section. The process includes withdrawing a reboiler draw stream from the still section and heating the reboiler draw stream in a reboiler to form a reboiler inlet stream. The process includes injecting the reboiler inlet stream into the primary stahl section, stripping water from the water rich glycol with the stripping gas, and withdrawing a still stripping gas stream from a top portion of the still section. A lean glycol polishing discharge stream is withdrawn from a bottom portion of the polishing stahl section.

A liquid distributor is used as an internal column component for a defined distribution of a liquid flowing downward within a column. The liquid distributor includes at least a bottom and side walls which constitute a container for the accommodation and defined distribution of the liquid. The bottom and at least one of the side walls are constructed from panels that are connected to each other. The panel or panels of the at least one side wall include a fiber composite material. A column and a method for separating substance mixtures are also provided.

With the invention a washing apparatus and a process for the efficient separation and recovery of methanol from waste gases loaded with methanol is proposed, wherein the invention also can be used in an integrated flow chart for the production and processing of methanol. The methanol fractions separated from the waste gases are recovered within the already existing, distillative processing of the crude methanol to pure methanol, so that no separate apparatuses are required for the recovery of the methanol from the loaded scrubber waste waters. The valuable substance methanol is recovered and the impact on the environment is reduced. By particular aspects of the invention the total degree of methanol separation can be adapted according to the locally applicable emission limit values.

Disclosed is a vapor splitter including: a chimney tray dividing an internal space of a housing into an upper space and a lower space; a chimney provided on the chimney tray to enable the upper space and the lower space to communicate with each other; a cap covering the chimney with a gap therebetween such that a gas discharge hole is formed so that gas, coming out through the chimney, can be transferred to the upper space through the gas discharge hole; a liquid feeding unit for feeding liquid to the upper space; and a liquid discharging unit for discharging the liquid out of the upper space. The size of the gas discharge hole is adjusted by controlling the height of the liquid collected on the chimney. Further disclosed is a method of adjusting a vapor split ratio using the vapor splitter.

The invention relates to a system for transferring mass with the capturing of solids via the induction of an electromagnetic field, comprising a plurality of cells formed in a plurality of discs forming an assembly of means for generating a membrane and electromagnetic field. The liquid membranes formed in this assembly collapse upon contact with a gaseous current. The collapsed liquid material covers the suspended particles and removes same via decanting, and the cells of the membrane also increase the speed of the gaseous current and cause same to impinge on the surface of the liquid, thereby improving the transferral of the vapour to the gas. The system also has means for generating an electromagnetic field that are electrically energised in order to provide an electromagnetic field to the assembly, such that the solids circulating after the rupture of the liquid membrane are attracted to each disc depending on the ionic behaviour thereof. The system also has means for capturing solids that are radially adjusted in the space between discs, and means for removing solids that are adjusted to the capturing means for removing or carrying the captured solids.

A system and a method for the recovery of carbon dioxide from a gas containing it. The system of the invention includes: pressurizing means for pressurizing the gas, an absorption tank for absorbing into water the carbon dioxide contained in a gas pressurized with the pressurizing means, a desorption tank for desorbing from water the carbon dioxide absorbed in water, means for circulating water from the absorption tank into the desorption tank and from the desorption tank back into the absorption tank, and recovering means for the recovery of carbon dioxide capable of being desorbed from the water. The system's absorption tank houses an agitator with a function of enabling water to circulate in the absorption tank by ejecting it into an air space of the absorption tank and by spreading in the absorption tank's air space over an area as extensive as possible.

A flare gas recovery system includes a primary gas sweetening unit; and a liquid-driven ejector in continuous fluid communication with the primary gas sweetening unit. The ejector includes an inlet configured to receive a motive fluid including a regenerable amine solvent in a rich state from the primary gas sweetening unit; a gas inlet configured to receive a suction fluid including a gas; and a fluid outlet configured to either directly or indirectly discharge to the primary gas sweetening unit a two-phase fluid including a mixture of the suction fluid and the amine solvent in a rich state.

A method for obtaining water from ambient air, wherein the method contains at least the following method steps: contacting the ambient air with at least one liquid absorbent for absorbing at least a part of the water contained in the ambient air; conveying an absorbent diluted by the absorbed water to a first heat exchanger; transferring the diluted absorbent into at least one desorption device. Therein, water desorbed in the desorption device is conveyed to the first heat exchanger, wherein cooling of the desorbed water is effected by means of the diluted absorbent by means of the first heat exchanger. Furthermore, disclosed is a device for obtaining water from ambient air.
