Improved Lime Mud Kiln Control System. A Lime Mud Kiln consists of three sequential operating zones drying, heating, and calcining. To achieve proper calcination, lime is subjected to the calcining temperature for a certain length of the kiln.
Optimized Wet Scrubber Design for Lime Kilns. A properly designed wet scrubber is a highly efficient approach to controlling lime kiln emissions which contain SO2 and HCl acid gases, metals, and particulate matter. A Venturi scrubber followed by a crossflow entrainment separator has the advantages of a small footprint.
Lime Kiln Process presents one of the most challenging measurement and control solutions in the Pulp and Paper mills. The complex dynamics and multivariable nature of the lime kiln process, with its nonlinear reaction kinetics, long time delays and variable feed characteristics, make the process inherently difficult to operate efficiently.

Lime kiln dust is a very fine material having unique chemical properties of limestone and lime along with silicates and other inert materials, which make the lime kiln dust highly suitable in agricultural uses. Depending on the concentration calcium carbonate it has obtained from limematerial, lime kiln dust can be effectively used in soilliming process.
Additionally, optimization of flame shape and precise control of the overall heat balance prevents overfiring in any section of the kiln. LKOS can be installed both on new kilns and as a retrofit to existing Lime Kilns. In cases where an existing control scheme has been replaced, Pulp Mill owners have typically realized the following benefits.
