The Kinetics of Calcination of High Calcium Limestone
The kinetics of calcination of a high calcium type of limestone was studied. Ukpilla limestone found in the central region of Nigeria was studied. The limestone composition shows that the limestone has 51.29% calcium oxide and 41.53% loss on ignition and magnesium oxide content of 2.23%. The following parameters were determined; diffusion coefficient of lime layer, and mass transfer coefficient...
متن کاملCrystallographic transformation of limestone during calcination under CO2.
The calcination reaction of limestone (CaCO3) to yield lime (CaO) is at the heart of many industrial applications as well as natural processes. In the recently emerged calcium-looping technology, CO2 capture is accomplished by the carbonation of CaO in a gas-solid reactor (carbonator). CaO is derived by the calcination of limestone in a calciner reactor under necessarily high CO2 partial pressu...
متن کاملModeling and Simulation of Limestone Calcination in Rotary Kilns
A one-dimensional mathematical model was developed for the simulation of limestone calcination in rotary kilns. The model is comprised of ordinary differential equations derived from mass and energy conservation principles. The system of equations is solved by a fourth-order Runge-Kutta method. The model predicts, in the axial direction, temperature profiles for the bed of particles, the gas ph...
متن کاملFluidized Bed Desulfurization using Lime Obtained after Slow Calcination of Limestone Particles
In this work we have tested the fluidized bed desulfurization performance of lime particles obtained by means of a proprietary limestone slow calcination pre-treatment technique. This performance was compared to that of the parent untreated limestone particles. The occurrence of particle fragmentation and attrition during the fluidized bed operation was also investigated with a specific test pr...
متن کاملOptimization of Inland Container Transportation with and without Container Sharing
In this contribution we optimize the transportation of containers in the hinterland of a local area with one terminal and one depot for empty containers and trucks. There are several customers who want to receive goods by inbound containers and several customers who want to ship goods by outbound containers. Additionally, there are empty inbound containers and empty outbound containers. We pres...
