LIME KILN CONTROL USING SIMPLE ADVANCED REGULATORY CONTROL STRATEGY Serge Naud, PE Martin Emond, PE Top. Control inc. Lvis, Qubec, Canada ABSTRACT Lime Kiln is one piece of equipment amongst the most important in pulp bleaching process.
A financially successful advanced process control APC project requires a project manager with skills to adequately qualify the project, negotiate contracts, and shape project schedules. In most APC efforts, the volume of information is not large, but a precise understanding of process ...
The third recognizes that some control loops interact and can even fight each other, so building a decoupling network is another useful function block tool. A good example of this is a lime kiln where you are trying to control the temperature at both ends of the kiln.
1990-8-28Referring now to the drawings, there is shown in FIG. 1 a preferred embodiment of the lime sludge kiln of this invention, denoted generally by the numeral 2. The kiln 2 includes a cylindrical shell 4 made of steel. The shell 4 is mounted in an inclined manner and is rotated about its axis by a standard rotational drive not shown.
1991-2-19The control of alkali concentration is accomplished outside of the kiln in a lime mud washer which reduces the alkali concentration by dilution with water to a 20 solids mixture, and on a lime sludge filter, which unit reduces the alkali concentration by dilution again and then by removal of 75 to 80 of the alkali by vacuum filtration.

This guide addresses the use of CCPs as a stabilizing agent without the addition of other materials however, stabilization or chemical fixation may also be achieved by using combinations of CCPs and other products such as lime, lime kiln dust, cement kiln dust, cement, and others.
2012-2-81.2 The CCPs that are suited to this application include fly ash, spent dry scrubber sorbents, and certain advanced sulfur control by-products from processes such as duct injection and fluidized-bed combustion FBC.
This pulp mill is very energy efficient, using only natural gas as the fuel source in the lime kiln process and black liquor and bark as fuel sources in the other processes. In 2000, Yokogawa Indonesia installed CENTUM CS, a UNIX-based production control system PCS, to control all operations at this mill.
