A sorbent injection system is the simplest method of SO 2 removal from flue gas. Sorbent generally used in this system are limestone (CaCO 3), dolomite (CaCO 3 ·MgCO 3), lime (CaO), or hydrated lime (Ca(OH) 2).Based on location of injection of sorbent, this system is classified into furnace sorbent injection (FSI), economizer sorbent injection (ESI), duct sorbent injection (DSI) (Figure ...
Hazardouswaste management Hazardouswaste management Treatment, storage, and disposal: Several options are available for hazardouswaste management. The most desirable is to reduce the quantity of waste at its source or to recycle the materials for some other productive use. Nevertheless, while reduction and recycling are desirable options, they are not regarded as the final remedy to the ...
Process equipment, instrumentation, and valves selected for use in lime slurry systems should limit cavities, cracks and void areas. Even a small collection point of lime can cause equipment failure and countless hours of downtime and maintenance. The ideal product to supplement lime slurry should be able to clean itself and break apart scale.
Hydrated lime requires care during handling both to prevent it from escaping into the surrounding atmosphere, but also to avert contamination of the hydrated line from any airborne particles. Caution should be exercised to shield the hydrated lime from moisture or from contaminants containing moisture, which may trigger a chemical reaction that ...

Aug 01, 2017· What Are Common Lime Slaking Problems Protocols? Lime in general has many advantages but there are some issues that occur with lime slurry feed systems such as clogging of metering pumps and inlet valves and incrustation of pH probes. This happens due to the wear and tear of continuous usage or malpractices and handling during slaking.
Lime Mixing Tanks, Lime Storage Tanks, Lime Dosing Tanks, Lime Batching Tanks and Lime Maturation Tanks. All provided with internal sloped floors to the tank outlet. The long term experience of Filquip with lime systems allows us to design packages that minimise the common lime problems associated with Blockages and Scale build up.
The addition of lime slurry to this stream can also remove any oils and/or heavy metals which may cause problems for discharging the stream. This system with lime addition can process the many and varied plant waste streams which are traditionally sent to the bottom ash pond.

For large applications lime may have merit as the cost of operation may be less but only if a large lime handling system is in place (lime silo, dry lime feed, etc.). We also manufacture a complete line of Fluoride Reduction Systems for industrial wastewater. These include small batch systems for low volume concentrated wastewater or continuous ...
value, the system will send a signal to the operator that there is a problem and, at the same time, will make a check of the installation in order to find it. The supply, as per the that you can see on the right, is composed by: A batch feeder (1), complete with mixer with sinter breaker (2); A hopper (3) complete with pneumatic vibrator (4)
An Overview Of Lime Slaking And Factors That Affect The Process By: Mohamad Hassibi Chemco Systems, November 1999 Revision 1 – February 2009 ABSTRACT Since lime slaking is an integral part of treatment systems in water, wastewater, air pollution, and process industries, its performance will influence the overall effectiveness
When water contains high amounts of magnesium hardness, split treatment may be used. Approximately 80 percent of the water is treated with excess lime to remove magnesium at a pH above 11, after which it is blended with 20 percent of the source water.
lime handling systems problems and remedies. Lime feed equipment can be a water treatment operators worst enemy or best friend.
