Overview

• Lextran Ltd. is a private company formed in 1997
  by Ludan Engineering Co. Ltd. one of Israels
  leading engineering companies with 700 employees.
• Lextran has developed a unique and patented gas
  cleaning technology that removes pollutants from
  flue gasses emitted by power plants and other
  industrial installations.
• Granted patents EU 1225967 US
  6,881,243
• Pending Hg patents EU 10/596,400 USA
  04806657.5
• Registered Patent, for using of Reagent
  132347
• Lextran has set its goals in reducing the air
  pollution by developing a cost effective
  installation for controlling the emissions of
  Nitrogen Oxides (NOx), Sulphur Oxides (SOx),
  Mercury (Hg) and other heavy metals.

The Business opportunity

• The reduction of the air pollution from power
  plants are a subject of great importance.
• Nitrogen Oxides (NOx), Sulphur Oxides (SOx),
  Mercury (Hg) and other heavy metals emitted by
  burning fuel, are an ecological burden of the
  first degree.
• Most of the governments and the environmental
  enforcing bodies have set strict standards to
  prevent dangerous pollutants discharge to the
  atmosphere.
• Lextran patented processes are cost effective and
  user friendly compare to any existing
  conventional solutions

Air Pollution Lethal Legacy

• In the US, several hundred older, coal-burning
  power plants across the nation are still
  operating without updated or no pollution
  controls. Pollution from these plants pose severe
  threats to the public health and the environment
• Asthma attacks emergency room visits - More
  than 6 millions asthma attacks.
• Premature mortality - 40,000 premature deaths
  every year.
• Loss of Aquatic and forest ecosystems - The
  largest source of the nitrogen and sulfur
  pollution that causes the acid rain.
• Human development and neurological damage -
  Coal-burning plants are the largest domestic
  industrial known source of mercury.

Lextran Technology

• The Lextran DeSOx DeNOx DeHg technology is a
  unique, patented 3 in 1 gas cleaning technology
  using a wet scrubber employing the Lextran
  liquid catalyst in a water emulsion, to treat
  SOx, NOx and Mercury. These 3 major pollutants
  are purged in one wet scrubber.
• The Lextran process is a single step,
  simultaneous multi pollutant removal approach.
  The chemistry is complex and involves mass
  transfer between gas and two liquid phases and a
  set of chemical reactions.
• The Lextran process meets or substantially
  exceeds all current regulatory requirements for
  coal fired power plants
• Almost complete removal of SOx
• Up to 70 removal of NOx
• Almost complete removal of Mercury
• It is a very simple installation with only a
  minimum of equipment and only liquid reagents,
  and it requires a relatively small footprint.

Process Description

• Utilization of the Lextran chemistry is achieved
  using the following steps
• Absorption of SO2 and N2O3 in the Lextran-water
  emulsion in a conventional gas-liquid contacting
  absorption tower.
• Oxidation of the Lextran-oxides complex in
  oxidation tank at the bottom of the absorber,
  using excess of oxygen from the flue gas.
• Removing of the water dissolved salt from the
  system by separating the aqueous phase from the
  Lextran phase, through a constant bleed from the
  circulation stream across the scrubber into the
  decanter.
• The bleed stream into the decanter passes a
  filter to remove accumulated particulate matter.
• Neutralization of the acids using basic compounds
  such as 25 NH4OH to form Ammonium Nitrate and
  Ammonium Sulphate salts which can be used as a
  fertilizer.

The Market Segments

• The Lextran process has applicability in five
  (5) major market segments
• Electric power plants burning coal
• Electric power plants burning heavy fuel oil
• Diesel power plants
• Industries steel manufacturing, oil refining,
  pulp and paper, etc.
• Solid waste management incinerators

13
Market Size

• The worldwide annual revenues for power plant air
  pollution control in 2005 were estimated as
  US34.3 billion and the annual capital
  expenditure in DeSNox is about US 13 billion.
  Lextrans addressable markets segments are the
  following
• In Coal Power plants is US8,24 billion.
• In HFO (Residual oil) plant is US 1.07
  billion.
• Increasing focus on DeSNOx will greatly increase
  the market size worldwide in the 2010-2012
  periods due to the concerns about Mercury and
  other heavy metal pollutants and the related
  enforcements regulations.
• Almost 60 of all Coal projects are being built
  for the U.S., China, Mediterranean and Eastern
  European countries, that have recently joint the
  European Community, such as Poland, Romania,
  Bulgaria.

Lextrans key benefits

• Direct Benefit - Compliance with Clean Air Act
  and Regulations-
• In Coal based Power plants Lextran process is
  the simple and cost efficient solution to comply
  with the stringent Clean Air regulations.
• In Heavy Fuel oil Power plants (Steam and Diesel)
  Lextran removes almost 100, no matter what the
  is sulfur content.
• By Products - Ammonium nitrate and ammonium
  sulfate can be utilized by the fertilizer
  industry.

21
Lextrans key benefits (continuation)

• New or Retrofit - The benefits apply to both new
  power plants and retrofits.
• EPA revised clean air regulations mandate DeSNOx
  for every coal power plant, many of which were
  previously exempt.
• The Lextran process requires a small footprint
  and can be constructed while the plant continues
  to operate. Only a few days of connection are
  needed to become operational.
