摘要:
The invention relates to an oil scrubbing column (1), in which it is provided according to the invention that the second mass transfer trays (100) respectively have a plurality of run-off elements (101), in particular in the form of angle profiles, which run parallel to one another and at a distance from one another, wherein the run-off elements (101) respectively have a first and a second run-off surface (102a, 103a), wherein the two run-off surfaces (102a, 103a) run towards one another along the longitudinal axis (L) in the direction of the petroleum section (20) and meet to form an edge (104), which is made to extend transversely to the longitudinal axis (L), and so the scrubbing agent (W', W") imparted to the edges (104) of the run-off elements (101) flow off from the respective run-off element (101) to both sides of the respective edge (104) by way of the run-off surfaces (102a, 103a), and wherein the number of second mass transfer trays (100) in the oil section (21) is greater than the number of first mass transfer trays (16) in the petroleum section (20), and wherein the petroleum section (20) has a smaller length (A) along the longitudinal axis (L) than the oil section (21), and wherein the first mass transfer trays (16) are formed as sieve trays, bubble trays and/or valve trays.
摘要:
A method and system for for reducing ion concentration of a solution and converting gas. The system comprising a multi-chamber unitary dialysis cell comprising a gas chamber, a product chamber, and an acid chamber. Ion exchange barriers separate the chambers of the dialysis cell. A first anion exchange barrier is positioned between the product chamber and the acid chamber and a first cation exchange barrier is positioned between the product chamber and the gas chamber. Anions from the solution being treated associate with cations from the acid chamber to form an acid solution in the acid chamber, and cations from the solution being treated associate with anions from the fluid comprising gas to form salt, thereby reducing the ion concentration of the solution being treated and converting at least a portion of the gas into salt.

Methods and systems for capture of carbon dioxide and electrochemical conversion of the captured carbon dioxide to organic products are disclosed. A method may include, but is not limited to, steps (A) to (C). Step (A) may introduce a solvent to a first compartment of an electrochemical cell. Step (B) may capture carbon dioxide with at least one of guanidine, a guanidine derivative, pyrimidine, or a pyrimidine derivative to form a carbamic zwitterion. Step (C) may apply an electrical potential between an anode and a cathode sufficient for the cathode to reduce the carbamic zwitterion to a product mixture.
