Amine Thermal Reclamation; Technology Development from Keywords: CO2 capture; amine; degradation; reclamation . amines during a reclaimer cycle. Amine reclaimer wastes (ARW) generated in CO2 capture processes demand suitable disposal means. Such wastes contain remaining amine, NH3 and other. Amine reclaimer wastes (ARW) generated in carbon capture and sequestration ( CCS) is categorized as a hazardous waste which needs proper disposal.

Reclaimr overall HSS formation rate is used for the mass balance over the reclaimer. Metadata Show full item record. Collections Institutt for kjemisk prosessteknologi . Recommendations provided to control the observed corrosion within the acceptable limit are by limiting the operation of the column from continuous to intermittent as per original design and if required to upgrade with the better corrosion resistant material with sufficient economic justification.

Oxidative degradation is the main form of MEA loss amune a capture process. Mass profiles, together with volume and temperature profiles within the reclaimer were found with respect of time. Dissolved oxygen concentration was studied in .
Amine reclaimer technologies Haaversen, Linn Christine Loe. The oxidative pathways leads principally to the formation of carboxylic acids reactions 1 and 2 are an example of degradation reaction.
Corrosion in Amine Reclaimer System
This causes loss of valuable and expensive amine that has to be replaced together with reduced solvent performance. This paper describes the root cause failure analysis of severe corrosion and erosion in amine reclaimer system including the overhead piping.
Concentration and temperature profiles were obtained. The following assumptions were taken for the mass balance: Estimation of MEA loss is done trough the following equations:. Feclaimer Carbon dioxide CO2 capture maine post-combustion by the use of amines is one of several technologies known to reduce the release of CO2 to the atmosphere when burning fossil fuels. The other fraction will lead to degradation products or will be emitted in the CO 2 stream.
The column has shell and tube typed exchangers in the downstream-end of qmine reclaimer system. Simulated data was compared to real reclaimer data to test how well the model explains the conditions in a thermal reclaimer. The reclaimer is periodically discharged to empty the accumulated salts.

It receives sour vapour from the 2nd reclaimer knock-out drum. Login or Vote Anonymously. Appendix D Thermal reclaiming of amine systems. MEA degradation leads to many degradation compounds. Oxidative degradation rate depends on Temperature, oxygen concentration in the flue gas, MEA concentration, SO2 concentration in the flue gas and CO 2 loading .
Where, Estimation of heat stable salts formation follows from the removal rates and stoichimetry of the reclzimer Skip to main content. The following reaction rate has been derived experimentally:. Even though the simulated data did not reclaimeg the curves from the real data accurately, the simulations are believed to present the conditions in a reclaimer well.
This reaction model is a simplified one, since in reality there are numerous degradation products detected in amine reclaimer samples that could form heat stable salts. The figure below show the results: An ordinary differential equation ODE solver was used to solve the set of differential equations. When the oxidative degradation zmine assumed to be 0. Sulfinol Reclaimer column redlaimer utilized to remove oxozolidone from lean sulfinol solution containing sulfolane, DIPA, water, oxozolidone, H2S and CO2 which is heated by medium pressure feclaimer.
The reclaimer system was operated continuously, irrespective of the limit of oxozolidone content which is not as per the design specifications thereby increasing the exposure between carbon steel material parts of the system to the corrosive environment more than design.
The reactions lead to degradation products and formation of HSS.
