| FOREWORD |
Welcome
About 5 years ago, as I took retirement from the
corporate world, the idea to offer front-end engineering
design services to the process industry came from
a long time friend, Mr. K.G. Tuli.
And, that my forty-odd years experience ought to
be shared with the industry. This also appeared
to be the need of the hour. And thus, Spectra Dynamics
Limited was established in participation with Mr.
Tuli and Mr. Patel of Paramount Limited.
The
industry response has been overwhelming.
And, this would not be possible without
the support and encouragement of
our friends and associates across
the industry. I take this opportunity
to thank you personally and initiate
this formal quarterly newsletter.
The publication will serve to keep
you informed of the expansions in
our activities as well as provide
a medium of periodic communication.

| FROM
THE ED'S DESK |
With the dynamic
growth and development in India,
we are proud to assert our role in
the areas of technology and engineering.
It is with great pride and joy that
we serve and bolster the process
industry. And, we continue to further
develop our competence and skills
to meet and exceed your expectations
and requirements.
Going forward,
we continue to see a strong requirement
for process-centric design and engineering
services. We would make every endeavour
to continue to be innovative and diligent
in our design – and thereby provide
industry-leading services to you. The
theme of this edition is one of our core
strengths: Ammonia-related systems. I
hope that you will enjoy reading this
and future editions.

| TECHNICAL
PERSPECTIVE – AMMONIA RECOVERY
SYSTEMS |
|
Ammonical salt solutions
require the removal of ammonia prior
to their discharge, in order to meet
the statutory norms. Moreover, it
is not judicious to lose a valuable
commodity like Ammonia in the waste
stream.
Spectra has developed
an innovative technology to recover
ammonia in aqueous solution or as
anhydrous gas. The process has the
advantages of high ammonia recovery,
low energy and capital costs. The
plants generally have an attractive
payback period. The process is relatively
simple to operate and uses routine
equipment. Various forms of this
technology are commercially used
in several plants.

| SUCCESSFUL
AMMONIA RECOVERY USING
LIME TREATMENT |
| |
Traditional technology
utilizes caustic soda to treat
ammonia-based streams. Although
these systems work well, they are
becoming increasingly uneconomical
due to the sustained high prices
of caustic soda. Lime treatment
could prove to be a worthy alternate;
however the rich-slurry streams
resulting from the lime treatment
provide stiff challenges. Handling
of these streams, especially in
columns, is difficult due to their
choking tendency.
|
|
Recently, Spectra
developed an innovative technology
to recover Anhydrous Ammonia from
this slurry. The slurry-stream
was handled in a column using specially
designed non-choking trays, while
still ensuring satisfactory vapour-liquid
contact. The ammonia recovery plant
using a column with these special
type trays has been installed and
has been performing on-spec as
per the design requirements.
ENERGY
INTEGRATION TO MINIMIZE UTILITY
REQUIREMENTS
Process conditions
often require heating to moderately
high temperatures. And, it may
be possible to utilize hot water
instead of steam for these applications.
Hot water is easy to generate,
handle and recycle. And, most importantly,
it is much less expensive than
steam.
Spectra carried
out the basic and detailed engineering
for the revamp of one such plant
using moderately high temperatures.
Significant reduction in the steam
requirements especially from the
column reboilers were reaped as
hot water systems replaced steam.
The revamps were executed successfully
and the plant continues to perform
on-spec, while reducing the utility
costs considerably. The efficiency
of the associated gas turbine went
up from 63% to 78%.

SELECTED
NEW PROJECTS
Spectra continues
to be been awarded several major
projects with some industry-first
type applications. Selected one
are:
 |
Process Design Package
for a Specialty Amine Facility |
| |
Spectra recently began work on developing the
FEED package for a Gujarat-based specialty
amine manufacturing company. The project
was awarded to Spectra considering its
competence, quality of documents delivery
and the track-record for timely project
completion.
|
|
| |
|
| |
Conceptual & Basic
Engineering for a Unique
Specialty Weedicide Plant |
| |
Spectra is developing a unique first-of-its-kind
design for a specialty weedicide plant
coming up in Gujarat. Spectra has completed
the conceptual & basic design phases
and the project is at the detailed engineering
stage.
|
| |
|
|
| |
Basic
Engineering for a DHDT Naphtha
Stabilizer Unit |
| |
Spectra has carried
out Basic Engineering for the
DHDT Naphtha Stabilizer for
a major Public sector Refinery
in North-eastern India. Simulation
and PFD were developed for
the two cases of operation
and the balance plant design
was successfully carried out
for the governing case.

| TRENDS
IN THE PROCESS INDUSTRY |
The Indian process
industry continues to bustle with activity.
Several new projects are envisaged
across industry segments:
| |
Oil & Gas
Industry |
| |
The exploration and
production industry has been
abuzz with recent discoveries
by Cairn India (oil find, Rajasthan)
and Reliance Industries Limited
(Gas find, offshore KG basin).
Although, the traditional giant
ONGC continues to hold the
lion share of the market. Marginal
players like HOEC, Selan Exploration,
Canoro Resources and others
have also been increasing activities
with international companies
coming onto the scene.
|
| |
|
| |
Refining
Industry |
| |
The rising demands
for the various refinery products
have led to several new projects
in the refinery market. New
projects include the Guru Govind
Singh Refinery in Punjab, Bina
Refinery in Madhya Pradesh
by public sector units (PSUs);
Reliance Industries Limited
and Essar Oil in Gujarat. Several
major expansions are also coming
up at various existing refineries.
|
| |
|
|
| |
Petrochemicals & Chemicals |
| |
Several major projects
are on the cards with private
enterprise and the PSUs both
being active. ONGC is getting
started with a major project
in Gujarat. GACL is forming
a joint venture with Dow Chemicals
for setting up a large chemicals
facility. Mid-size players
like UPL, INOX, Gharda, SRF,
Rallis and others are also
busy with major upcoming expansions.
