Method for producing calcium carbonate solids from alkaline minerals
The invention relates to a method for producing calcium carbonate solids (8) from an alkaline mineral (1), comprising the following method steps: supplying the alkaline mineral (1) and an extraction agent (3) into a reaction tank (2). The alkaline mineral (1) and the extraction agent (3) are stirred in a reaction tank (2), thereby forming a first suspension (4). The first suspension (4) is discharged from the reactor tank (2) and a calcium-containing liquid phase (5) is separated from the first suspension (4) and the liquid phase (5) is transferred into a carbonation tank (6). A CO2-containing gas (7) is supplied into the carbonation tank (6), where the consumption of CO2 results in precipitation of calcium carbonate solids (8), thereby producing a second suspension (9) and nucleation and growth (8) of the calcium carbonate solids. Furthermore, a measured value of the consumed CO2 is determined by at least one sensor (10).
本发明涉及一种由碱性矿物(1)生产碳酸钙固体(8)的方法，包括以下方法步骤：将碱性矿物(1)和萃取剂(3)供应到反应罐(2)中。在反应罐(2)中搅拌碱性矿物(1)和萃取剂(3)，从而形成第一悬浮液(4)。从反应器罐(2)中排出第一悬浮液(4)，并从第一悬浮液(4)中分离出含钙的液相(5)，并将液相(5)转移至碳酸化罐(6)中。将含CO2的气体(7)供应到碳酸化罐(6)中，其中CO2的消耗导致碳酸钙固体(8)沉淀，从而产生第二悬浮液(9)并且使碳酸钙固体形核和生长(8)。此外，消耗的CO2的测量值由至少一个传感器(10)确定。
