A Safire in the Rough
A multi-phase flow meter, Los
Alamos National Laboratory’s
Safire provides noninvasive,
real-time and accurate estimates of oil production for
every well. Jointly developed
with Chevron ETC and GE
Oil & Gas, Safire achieves measurement rates as high as 100
readings/sec, including computation time.
Safire is based on SFAI (swept frequency acoustic interferometry). SFAI uses
frequency-chirp signal propagation (wideband ultrasonic frequency) through a
multi-phase medium to extract frequency-dependent physical properties of said
medium. Reservoir engineers then use the propagation time and the attenuation of the chirp signal as a function of frequency to extract both fluid flow and
multi-phase fluid composition information.
Designed simple to use, Safire enables continuous measurements in
fast-changing oil flows in rod-pumped wells, as well as other wells. Safire’s
ability to provide accurate, real-time volumetric measurements of oil flow from
wells means better reservoir management, accelerated production and huge cost
savings by eliminating environmentally unsafe separations tanks.

Calcium Loop for Carbon Capture
Carbon capture and
sequestration (CCS) isn’t
only suitable for new
power plants, but more
essential in retrofitting
existing ones. Because of
this retrofitting nature,
CCS is regarded by the
Agency as the single
technology most capable
of carbon dioxide (CO2)
reduction in the world
and could account for
more than 20% of global
CO2 abatement by 2050.
carbon capture technologies are all costly.
Industrial Technology Research Institute’s HECLOT: High efficiency
calcium looping technology is a carbon capture technology for fossil power
plants and other industrial emission reductions. It loops calcium oxide and calcium carbonate (CaO/CaCO3) in a regenerative cycle to remove carbon dioxide
in the post-combustion fumes of boilers. With integrated hydration, the technology has much higher CO2 capture efficiency and, potentially, much lower
cost than other technologies.
Moreover, high-temperature operation and a high-quality heat recovery
design keep energy consumption in CO2 capture much lower than other processes. The design has been validated in the field by a pilot unit. Based on data
from continuous operation, the design can meet the capture cost target of $30/
ton of CO2 at a capacity as low as 50 MWe while maintaining electricity generation cost below $80/MWh.

Clean Water for All
As populations grow and water needs accelerate,
more viable water treatment solutions
are essential to support a variety
of fast-growing applications.
However, users trying to treat
water with traditional filters
often complain that they’re experiencing
too much downtime, high maintenance and
filter costs, high fines and surcharges and high
expectations to conserve and reuse water. Traditional
bag and cartridge filters are holding them back.
Clean Filtration Technologies LLC, a subsidiary
of The Dow Chemical Company, has developed the TEQUATIC PLUS fine
particle filter as a solution to these problems. The filter is a disruptive technology
that, unlike conventional filters, can clean itself. Constant fouling and plugging
are things of the past, replaced by high uptime and low maintenance. The design
combines continuous cleaning, cross-flow filtration, centrifugal separation and
solids collection in one unit, without requiring a motor and related power consumption. This enables users to cost-effectively process water containing high and
variable solids from 1 to > 10,000 mg/L down to 10 micrometers without constant filter changes, and in the presence of fats, oils and greases. Sustainability is
enhanced through less disposal and a high water recovery rate up to 99%.
