The Latest Advancements in CNG Ocean Transport Charles
White , EnerSea Transport LLC Efforts
to commercialize
marine CNG
technology have made solid progress in recent
years despite high steel prices and tight shipyard
capacity. While the first purchase order for a
CNG ship is still in the offing, an impressive
array of companies is committing resources to
push the technology forward. EnerSea has been
at the forefront of this effort. The company has
recently received investments from Mitsui and
Tanker Pacific. Britton has been asked to review
the status, direction, remaining issues and timing
for CNG to reach full commercialization.

Reforming of Natural Gas Alan
K. Richards, consultant, GTL Technologies
Richards
has devised technology to convert methane and
other light alkanes via methane-sulfonic acid,
sulfene, and other pathways into methanol, DME
and/or ethylene. This process proposes to avoid
the expensive step of reforming of natural gas
with oxygen to produce syngas, thereby saving
space over typical methanol, DME or ethylene production
methods. Space and weight savings are especially
valuable offshore. Richards has been asked to
describe this technology in detail.

Waller, founder, Waller Marine Among other projects,
Waller Marine has designed at least four floating
power plants up to 22o MW that have been constructed.
The firm has also designed floating methanol plants.
Waller has been asked to review the current state
of commercialization for floating power plants and
floating methanol plants.

Offshore GTL - Advancements at the Aje Field Branch Russell, VP upstream,
Syntroleum Syntroleum's
GTL technology does not require an oxygen separation
plant, and therefore, is better suited for offshore
application than most other GTL processes. Russell
has been asked to review his company's latest
efforts to apply GTL technology in
the Aje field offshore Nigeria.
Microchannel
Heat Exchangers: Applications and Limitations Lee
Tonkovich, manager, Technology Development Ctr,
Velocys
Microchannel heat exchangers offer improved heat-transfer
efficiency over conventional exchangers because
the volume of gas or liquid being heated or cooled
is reduced relative to the surface area of the
exchanger. Consequently, a microchannel exchanger
one-fifth the size of a conventional unit may
suffice for a given heat-exchange application.
Yet, limitations to microchannel heat exchangers,
such as manufacturing costs or fouling, may constrain
their application in the demanding natural gas
arena. Tonkovich has been asked to describe what
makes microchannel heat exchangers promising and
the challenges the industry must overcome to make
them more competitive for the energy industry.

Micro-Channel Heat Exchanger: Potential for
Smaller or Mid-Scale Gas Monetization Mark Wood, Chart Industries Chart
Industries manufactures both microchannel heat
exchangers and conventional brazed-aluminum plate-fin
exchangers. Wood has knowledge of the advantages
and disadvantages of both technologies. He will
describe the prospects for applying microchannel
exchangers for small and mid-scale gas reserves,
and the tradeoffs gas developers must consider
as they evaluate one exchanger over another.

Heat Exchangers and Reactors Tony
Bowdery, Heatric Heatric has been involved in the
commercial design and manufacturing of microchannel
heat exchangers called Printed Circuit Heat Exchangers
(PCHEs) since 1985 and there are now thousands
of tons of such exchangers in operation in hundreds
of different services around the world. Many of
them are installed on offshore oil & gas platforms
where the size and weight advantages of microchannel
exchangers are of obvious benefit. Typical applications
include gas compression cooling at pressures up
to 8700psi (600bar) and gas/gas exchangers for
dewpoint control systems.
More recently Heatric has developed a compact
reactor called a Printer Circuit Reactor (PCR)
utilizing the same proven technology & manufacturing
techniques as for PCHEs. Chemical reaction, rectification,
stripping, mixing and absorption, as well as boiling
and condensation, can be incorporated into compact
integrated process modules. Heatric's steam reformer
has been demonstrated both in house and at the
University of Sydney and it lies at the heart
of a commercial prototype Hydrogen Production
Unit supplied to an industrial user in California.
A compact methanol production unit is also under
development.
