RESUMO
FeCO3 is present as scales in process equipment, corrosion products, geological systems, and carbon storage. It is therefore crucial to investigate the properties of FeCO3 to understand scaling in all these systems. However, FeCO3 is not commercially available, and when used in the lab it is either obtained through extraction of geological formations or synthesized in-house. Geologically formed FeCO3 contains multiple impurities, which will affect its overall properties, and the synthesized product is highly sensitive to either oxidation or the synthesis pathways. This work explores the parameter space of a synthesis route routinely and pathways for FeCO3. We characterized the structure of FeCO3 using X-ray powder diffraction and its thermal properties with thermogravimetric analysis and scanning electron microscopy. We show how synthesis parameters influence either the macroscopic or microscopic properties of the synthesized product. Our study serves as a guideline for future research regarding what parameters to choose when synthesizing FeCO3 and what product can be obtained. We herein present a novel fundamental understanding of FeCO3.
RESUMO
The lean vapor compressor (LVC) unit at Technology Centre Mongstad (TCM), Norway has been tested. The aim of this research has been to create knowledge on the process performance of LVC on the CO2 capture efficiency and energy profile of the TCM plant. The data presented in this paper is supplementary to the study "Results of the fourth Technology Centre Mongstad campaign: LVC testing" [1]. The dataset gives unique information on the LVC campaign in which 16 cases have been tested with various campaign process parameters such as LVC pressure, solvent flow, inlet flue gas CO2 concentration, and stripper pressure. Absorber and stripper process conditions were recorded during these tests and are presented.
