The BisCat filter system (photo)
combines the three process stages
of de-dusting, separation of acid
components and reduction of total
hydrocarbons and oxides of nitrogen
(NOx) in one unit. The system uses
high-temperature filters with ceramic
elements that enable the removal of
NOx, dioxins, mercury and volatile
organic compounds (VOCs) through
an integrated catalyst matrix. BisCat
ceramic catalyst filters are chemically
inert and corrosion-resistant. Particle
separation takes place with the aid
of filter elements made of mineral
fibers. These ceramic candles are
well proven and very flexible to use,
even with regard to modifications
of operating parameters, especially
at high gas temperatures. No cooling
of fluegases is required and no
thermal energy is wasted. Filter elements
are cleaned of separated dust
online during operation by means of
separate, compressed-air-jet pulses.
The single or multi-sectional housings
allow a maximum filter length
of 6 m. This means that even large
gas-volume flows can be cleaned.
By injecting lime-based reagents, inorganic
pollutants, such as HF, HCl
and SOx, can also be absorbed.
Applications include the cement
and glass industries, incinerators,
refineries and roasters. - GEA,

New wet electrostatic
precipitator for control of fines
In January, this company launched
its new HEI (high-energy ionizer) Wet
Electrostatic Precipitator (WESP)
system (photo). Said to be a breakthrough
in the advancement of stateof-the-art
fine-particulate-matter
control, the HEI WESP System incorporates
a unique discharge electrode
technology that can be sized
to specific applications, and concentrates
a high-intensity ionizing corona
in strategic areas within the collecting
tubes instead of distributing it
along the entire length of the tubes'

treatment area. The resultant particle
charging fields are two to three times
stronger than conventional precipitators
and deliver higher particulate
charges, higher migration velocities
and a smaller precipitator size for
gas capacities from 1,000 through
300,000 actual cubic feet per minute
(acfm), says the manufacturer. Unlike
other precipitators that utilize sprays,
overflow weirs or packed marble
beds, the HEI WESP incorporates
the Ultimix Conditioning System for
gas saturation and collection-tube
cleaning and the patented RotaBed
Pre-Scrubber for acid removal and
particulate-loading reduction. Typical
applications include submicron particulate-matter
scrubbing, aerosols,
mists and smoke removal. - Bionomic

Continuous monitoring of
pilot flames and flared gases
The E2T Quasar 2 series of instruments
(photo) is designed for continuous-duty
monitoring of pilot flame and
flared gases from flares. The base system
provides low-cost basic flare-pilot
monitoring capabilities. The advanced
model has an intensity milliampere
(mA) output that allows for a setpoint
mA level to be set in a user's distributed
control system (DCS) for both
the pilot and flaring status signals from
the same unit. Additional add-on features
are available for a configurable
product to meet a wide range of flare
types, monitoring requirements and
budget. Two models are available:
Quasar 2 M8100-EXP and Quasar 2
M8100-EXP Advanced. Scalable options
are available with the advanced
version and include continuous 4-20
mA, peak hold and decay, and power
supply with 85 to 265 V a.c. input. -
