As the name suggests, this project is aimed at finding the appropriate ways to utilise the excessive lime that is being produced by Fatima Fertilizer Company. As per the research, this excessive calcium carbonate can be utilised in the Calcium ammonium nitrate (CAN) plant, however due to various impurities like AN and P2O5 and the particle size of CC hinders the utilisation in CAN plant. Impurities cause a caking problem during the level build up. Furthermore, the very fine particle size of CC produced increases the particle size variation in final CAN product. Targeted regular CAN product is 2-4 mm in size. This research helped in formulating such ways where these impurities can be removed, and this excessive CC can be utilised in the in-house CAN plant or can be used elsewhere like in buildings or sand lime bricks.
