One of the major drawbacks that hinder the industrial competitiveness of the calcium looping (CaL) process for CO2 capture is the high temperature (∼930-950 °C) needed in practice to attain full calcination of limestone in a high CO2 partial pressure environment for short residence times as required. In this work, the multicycle CO2 capture performance of dolomite and limestone is analysed unde...

A study was done to determine whether broilers can regulate Ca intake when limestone is provided separately or mixed with a crumbled feed of variable Ca and P content, and the influence of this on performance and apparent ileal digestibility (AID) of Ca and P (AIDP). Twelve crumbled diets were fed from 10 to 20 d of age (8 replicates, 8 broilers/replicate). Diets A to D contained 0.28% nonphyta...

Abstract. Ensuring sustainable strategies to manage water resources in karst reservoirs requires a better understanding of the mechanisms responsible for conduits formation rock mass and development detection methods these hydrological geochemical processes. In this study, we monitored electrical conductivity two limestone core samples during controlled dissolution experiments. We interpret res...

Abstract Factors limiting foam injection for EOR application are exceptionally low rock permeability and exceedingly high salinity of the formation water. In this regard, using internal olefin sulfonate is investigated over a wide range (1, 5, 8, 10, 12% NaCl) through 10 mD limestone. The relationships between pressure drop (dP), apparent viscosity, liquid flow rate, total salinity, texture, le...

Limestone is a popular building stone worldwide. In Baku in Azerbaijan, local limestones have been used construction, including the walled historic city centre (Old City, Icherisheher). Located seismically-active area, prone to post-earthquake fires that can damage buildings and monuments. Here, we test fire resistance of limestone by measuring its physical (connected porosity, permeability, P-...
