higher filtering velocities, they are very much smaller then corresponding fabric collectors which are cleaned by either mechanical shaking or low pressure reverse air.

SCRUBBER

We designs, manufactured / imported and offer an highly efficient, engineered solution for reduction in smoke, grease, odor from the extract of hotels and restaurants through a scrubber which operates on the principle of electrostatic precipitation.

 

How It Works?

The technology is based on the principle of two stage electrostatic air filtration.

Fine sub- micron suspended particles are electro statically  charged using high voltage electric field.

These charged particles get attracted and precipitated on opposite charged electrode plates.

Wet Scrubber- Spray type consists of a row of spray nozzles (PVC or GI) and a chamber or tank at the bottom that collects the water that falls through the air contacting many baffles.

Dry Scrubber – Contaminated air is drawn by the motor/blower through a washable metal mesh pre-filter which traps large dust particles. The remaining particles, some as small as 0.01 microns, pass into strong electrical field where the particulate receives an electrical charge. The charged particles then pass into a collector plate section made up of a series of equally spaced parallel plates. Each alternate plate is charged with the same polarity as the particles, which repel, while the interleaving plates are grounded, which attract and collect the contaminants. The contaminants are held in these plates until they are washed away. Electronic Air Cleaners trap both wet and dry particulate.

Application Areas – Pharmaceutical Manufacturing, Food products Processing, Health care Facilities, Hospitals- OTS/ICUS, Offices of consultants, BPOs, IT industries

Technological advantage

–

Filtration efficiency– Ability of trapping the particles down to 0.01 micron. Equivalent to and better than other grade filters. Very low pressure drop- 0.5″ of W.C pressure drop across ESP.

Permanent filter– ESP never requires any replacement over the lifetime. It only requires periodic cleaning. Makes this ideal choice of fine pollutants like oil mist and fumes.

Gas Scrubber

ATIPL Gas Scrubber removes traces of liquid droplets from gas streams to protect downstream equipment from damage and failure. It is typically used upstream of gas treating equipment that contains dry desiccants or mechanical equipment such as compressors. It is also used downstream of equipment where liquids have condensed from the gas. The Gas Scrubber is designed to handle light liquid loads and does not take the place of a primary separator. Vessels are available from 12-inch to 72-inch OD with natural gas capacities to 200+ million standard cubic feet per day (MMscfd).

• Prompt, professional service, support and spare parts from local technicians in or near every major oil & gas producing region in the U.S. and numerous areas around the world

HOW IT WORK

The production stream first encounters the inlet diverter, which causes initial separation of gas from liquid. The heavier liquid descends while the gas rises. In the open area of the vessel, the stream slows even further and the larger liquid particles fall from the gas. Next the high efficiency mist extractor captures smaller liquid particles entrained in the gas. Liquids exit the bottom of the vessel and the scrubbed natural gas exits the top.

Vent Scrubber

ATIPL Vent Scrubber helps you run a safer and more environmentally responsible gas flare system by helping keep liquids out of your flare stack. It is a two-phase separator that scrubs free liquids from your vent gas stream prior to entering the relief and blow-down lines in your flare system. The unit is typically used downstream of gas treating equipment and can handle a wide range of flow rates. Versions for both onshore and offshore applications are available.

KEY BENEFITS

Performance

• Helps prevent liquids from entering the flare stack to help you run safer and cleaner operations

HOW IT WORKS

The production stream first encounters the inlet diverter, which causes initial separation of vent gas from liquid. The heavier liquid descends while the vent gas rises. Liquids exit the bottom of the vessel and the natural gas exits the top. With the optional skid-mounted system, the accumulated liquid is removed via a pneumatic level control and pump.

FUME AIR SCRUBBER

Fume air scrubbers are light duty wet scrubbers used for air pollution control. The term “fume scrubber” was made popular by the metal finishing industry, since the pollutants emanating from the open-top dip tanks were generally referred to as “fumes.” Fumes may consist of solid or liquid aerosols and/or vapors. Most of the dip tanks used in various metal finishing processes – such as anodizing, brightening, cleaning and plating – produce airborne vapors and liquid aerosols (mists).

Vapors are produced by virtue of one or more components in the bath having a high volatility. Many metal finishing processes run at elevated temperature, which increases the volatility of the bath constituents. Mists are generated either by mechanical agitation of the liquid in the bath or by bubbles forming and bursting as they escape from the liquid surface during an electrochemical process. Mist formation due to an electrochemical process leads to a much finer aerosol than that formed by mechanical agitation.

Fume air scrubbers generally incorporate nominal packed beds. They may use recycled water or water with a chemical additive such as sodium hydroxide. They are available in vertical counter-flow or horizontal cross-flow configuration. A variety of construction materials are also available, such as PVC, CPVC, polypropylene and FRP.

WET AIR SCRUBBER

Wet scrubbers include any device for removing contaminants or impurities from a gas stream using water. This may be motivated by process or environmental reasons. In the domain of air pollution control, the gas stream handled by wet scrubbers is always air mixed with a regulated pollutant that must be separated, usually at a high efficiency, before exhausting to atmosphere. ATIPL considers all factors of operation and installation in order to select the optimum design. We offer a complete range of services, consisting of engineering and design, instrumentation and controls, skid-mounting of equipment, installation, chemical storage tanks and metering pumps, wastewater pretreatment, and start-up.

Wet scrubbers are used to remove water-soluble gases and vapors, as well as particulates and aerosols. Gases are scrubbed by the process of diffusion constrained by vapor-liquid equilibrium. Particulates are scrubbed by the mechanical processes of impaction and interception, which are dependent on the size and speed of the particles relative to the size and speed of a target, such as a water droplet or wetted surface.

Often, gases that are rather insoluble in water may still be reduced using a wet scrubber by adding chemicals to the water to react with the insoluble gas, converting it to a component with greater solubility. This process is known as chemical reaction assisted gas absorption. Wet scrubbers used to carry out this process are simply called “chemical scrubbers.” Regardless of the application, the gas and water streams must be brought into intimate turbulent contact with one another. ATIPL  incorporates a variety of contacting methods, including random and structured packed beds, sieve trays, water jets, venturis, spray chambers, and fine bubble diffusion.
