drum scrubber working principle definition chemistry


gases, or both from industrial gas streams or stacks. Water chemistry is often extremely complicated in these scrubber systems because of the variety of oper-ations occurring simultaneously in the scrubber environment. 1. Heat transfer: The gas and water are often at different temperatures, so heat will be transferred in the scrubbing process. 2.

Scrubber - Wikipedia

The first air scrubber was designed to remove carbon dioxide from the air of an early submarine, the Ictineo I, a role for which they continue to be used today. Traditionally, the term "scrubber" has referred to pollution control devices that use liquid to wash unwanted pollutants from a gas stream.

Drum | musical instrument | Britannica

Drum, musical instrument, the sound of which is produced by the vibration of a stretched membrane (it is thus classified as a membranophone within the larger category of percussion instruments). Basically, a drum is either a tube or a bowl of wood, metal, or pottery (the "shell") covered at one or

Scrubber - an overview | ScienceDirect Topics

Equipped with a water seal, the venturi scrubber is especially designed for handling explosive gases in the safest possible manner. This applies directly to closed submerged arc furnaces that produce CO gas. The efficient and secure operating principle is to both cool and clean the gas and to quench sparks from the furnace.


2-stage wet scrubber designs. The most commonly used is a Mikropul Venturi Scrubber with a Packed Bed section. It is used to remove particu-late as well as gaseous contaminants from the gas stream. The principles of operation are as described for the Venturi scrubber and Packed Tower designs. The designs are optimized

The principle of the drum pump - Jessberger Drum pumps

With the shown principle of a drum pump, our most powerful universal motor (JP-280 with 825 Watt) can be used to transport all low-viscous to medium-viscous liquids from drums and containers. For the drum pump based on the principle of the centrifugal pump, the absolute limit range for the viscosity is about 1,000 mPas.

Rotary Scrubbers | McLanahan

Rotary Scrubbers. Rotary Scrubbers are used to wash crushed rock, ore, sand, gravel, construction aggregates and oil sands. They are high-capacity, high-retention machines that can accept large-sized feed material and are used primarily to remove water-soluble clays, deleterious materials and coatings providing a cleaner product

Gas Scrubber - Chemical Scrubber - Gas Scrubbing | Pollution ...

Effective Gas Scrubber removal efficiency is achieved by ensuring the appropriate contact time between the gas and the scrubbing liquid occurs. These systems incorporate a scrubbing vessel with a system fan, recycle pump, instrumentation and controls, mist eliminator, and exhaust stack.

Drum Scrubber Design and Selection

The drum scrubber model described in this paper considers the physical selection of the scrubber geometry and its drive power. It is based on testwork results that define the residence time necessary to provide the required degree of attrition. In most cases these will be results from either batch testing or continuous pilot (or bench) testing.

Flue-Gas Desulfurization ("Scrubbers")

The chemistry of desulfurization The liquid used to "wash" the flue gas is a water-based calcium solution. Limestone (CaCO3) is cheap and creates an alkaline environment in water: CaCO3 + H2O Ca++ + HCO3– + OH– This OH– radicals bind with SO 2 in solution to form a sulfur ion: SO2 + OH– HSO 3 – while water always dissociates a bit:

Scrubbers: The Major Types of Industrial Scrubbers

A dry industrial scrubber is composed of a reaction center where the sorbent or dry reaction material that absorbs contaminants is mixed with the polluted gas. Also within the system is a material component that aids in the removal of the reaction product, which is the dry sorbent bound to the pollutant.

Scrubbing | McLanahan

Scrubbing. Naturally occurring deposits of aggregates and minerals hardly ever meet the gradations necessary for use in our daily lives. When aggregates and minerals are initially liberated from the earth, and even after they are crushed in the processing plant, they can contain lumps or coatings of clay, soft rock, vegetation, crusher dust and other deleterious materials that are not ...
