1. WOWO/2014/148658 - METHOD FOR REGENERATING AMINE ABSORBENT USING PROTON DONOR MIXTURE25.09.2014
B01J 20/30
PCT/KR2013/002328KOREA INSTITUTE OF ENERGY RESEARCHBAEK, Il-Hyun
The present invention relates to a method for absorbing and regenerating carbon dioxide by adding and using a proton donor mixture for lowering regeneration energy after an amine absorbent, which is a carbon dioxide absorbent, is absorbed. The method comprises the steps of: preparing a proton donor mixture using an amine and a proton donor precursor; mixing the proton donor mixture with an amine to prepare an absorbent; injecting the absorbent into a carbon dioxide treatment apparatus including an absorption column and a regeneration column, and counter-currently moving the absorbent from the top portion to the bottom portion of the absorption column to absorb carbon dioxide moving from the bottom portion to the top portion of the absorption column; and moving the absorbent passing through the step of absorbing the carbon dioxide to the regeneration column and then regenerating the absorbent. The absorbent in which the proton donor mixture is mixed with the amine exhibits high regeneration efficiency even at a low temperature since the proton donor mixture gives protons to the absorbent when the absorbent is regenerated, and thus can be repeatedly used due to high thermal stability thereof and can have a long use lifespan.

2. WOWO/2014/146859 - METHOD FOR MONITORING AND REGULATING A FILLING LEVEL OF AN ABSORBENT OF A CO2 SEPARATING UNIT BEING IN OPERATION25.09.2014
B01D 53/14
PCT/EP2014/053441SIEMENS AKTIENGESELLSCHAFTFISCHER, Björn
The invention relates to a method for monitoring and regulating a filling level of an absorbent of a CO2 capture process (10) being in operation, comprising an absorbent circuit, in which an absorbent consisting of water and a dissolved, detergent additive is conveyed. In a first measuring process (20), measuring data on the density of the absorbent (25) and in a second measuring process (30) measuring data on the loading of the absorbent with CO2 (35) are captured. The dilution of the absorbent with water is calculated based on the measuring data during an evaluation process (40) and then, depending on the dilution of the absorbent with water, a make-up water is regulated to the absorbent circuit in a regulation process (50), such that likewise in transient processes an optimal absorption of CO2 is guaranteed through the dilution of the absorbent.

3. WOWO/2014/146861 - POWER GENERATION SYSTEM AND METHOD TO OPERATE25.09.2014
F01K 7/22
PCT/EP2014/053446SIEMENS AKTIENGESELLSCHAFTSTUXBERG, Anders
The invention relates to a power generation system (PGS) comprising: an oxy-fuel-burner (OXB), a steam cycle (RC), a recirculation line (RCL) extracting a part of said exhaust- fluid from said steam cycle (RC) and feeding said exhaust- fluid-stream into said oxy-fuel-burner (OXB). To improve efficiency a system and a method is proposed - providing at least one first feed-water-preheater (WPH1) and - wherein said steam cycle (RC) joins into said recirculation line (RCL) downstream said at least one first feed water pre- heater (WPH1) and - extracting a tenth exhaust-fluid-stream (EXH10) from said steam cycle (RC) downstream said first feed-water-pump (FWP1) as, - extracting an eighth exhaust-fluid-stream (EXH8) as carbon- dioxide downstream said first condenser (CON1), - wherein said at least one first feed water-preheater (WPH1) is heated with an exhaust-fluid-stream extracted from said first steam turbine (ST1), namely a fifth exhaust-fluid- stream (EXH5).

C01B 3/50
PCT/US2014/025185EXXONMOBIL RESEARCH AND ENGINEERING COMPANYBERLOWITZ, Paul, J.
In various aspects, systems and methods are provided for operating a molten carbonate fuel cell, such as a fuel cell assembly, with increased production of syngas or hydrogen while also reducing or minimizing the amount of CO2 exiting the fuel cell in the cathode exhaust stream. This can allow for improved efficiency of syngas production while also generating electrical power.

PCT/US2014/025208EXXONMOBIL RESEARCH AND ENGINEERING COMPANYBERLOWITZ, Paul, J.
In various aspects, systems and methods are provided for operating molten carbonate fuel cells in a refinery setting. The molten carbonate fuel cells can be used to provide hydrogen to various refinery processes, including providing hydrogen in place of using a carbon-based fuel for various combustion reactions. In a further aspect, CO2 -containing streams generated by refinery processes can also be used as input streams to the molten carbonate fuel cells.

In various aspects, systems and methods are provided for operating a molten carbonate fuel cell assembly at increased power density. This can be accomplished in part by performing an effective amount of an endothermic reaction within the fuel cell stack in an integrated manner. This can allow for increased power density while still maintaining a desired temperature differential within the fuel cell assembly.

PCT/US2014/025181EXXONMOBIL RESEARCH AND ENGINEERING COMPANYBERLOWITZ, Paul, J.
In various aspects, systems and methods are provided for operating a molten carbonate fuel cell with an excess of reformable fuel relative to the amount of oxidation performed in the anode of the fuel cell. Instead of selecting the operating conditions of a fuel cell to improve or maximize the electrical efficiency of the fuel cell, an excess of reformable fuel can be passed into the anode of the fuel cell to increase the chemical energy output of the fuel cell. This can lead to an increase in the total efficiency of the fuel cell based on the combined electrical efficiency and chemical efficiency of the fuel cell.
