    White liquor preparation | Flowserve - NAF Control Valves

    The lime kiln is a large, horizontal steel cylinder with a diameter of 2-4 meters and a length of 40-120 meters. The cylinder rotates at 1-3 revolutions per minute with a slope of 2-30 towards the burner. Some of the most difficult applications for valves are found in the white liquor plant. The green liquor is very erosive and has a strong

    The green liquor is first transferred to a slaker tank, where Ca0 from the lime kiln reacts with water to form calcium hydroxide (Ca(OH)2). From the slake, liquor flows through a series of agitated tanks, referred to as causticizers, that allow the causticizing reaction to go to completion (i.e., Ca(OH)2 reacts with Na2CO3 to form NaOH and CaCO3)

  • Mass and energy balances over the lime kiln in a kraft
    Mass and energy balances over the lime kiln in a kraft

    The purpose of this thesis is to create a model of the lime kiln that performs mass- and energy balances over the process. This model is to be integrated in the WinGEMS software that is used to simulate mill systems in the pulping industry. There is an existing lime kiln block in WinGEMS but since has proven inadequate and in need of replacement

    Sep 26, 2013 Gate valves or knife gates can be used in slurry service. With many gate valves, end users must be willing to sacrifice tight shut-off when they are used in lime slurry. Most gate valves have a wedge in which the gate is forced to close the valve. Knife gate valves have a sharpened edge to improve the ability to cut through solid particles
