Highlights of Some of the Articles
 LET THE GOVERNMENT SET UP A TASK FORCE FOR THE CHEMICAL INDUSTRY Like many other sectors of Industries, Indian chemical industry is also anxiously looking at the new Government of India that has been now formed after the elections, to provide necessary impetus for growth. With the global melt down proving to be a real problem now and the
impact being felt by the Indian chemical industry, there is great anxiety that the government should come forward to lay out a convincing road map for growth and progress.
 Of course, during the last few years, the price of crude oil and energy cost has been the most critical issue that confronted the Indian chemical industry. While the price of crude oil went beyond the roof, nothing worthwhile was done by the Government of India or Indian chemical industry to face the problems and overcome the difficulties. The problem solved itself to some extent when the price of crude oil came down in global sphere. Now , there is distinct possibility that the crude oil price may go up once again when the global recessionary trends would recede, that can create problems for the chemical industry in India. To sustain the growth of the chemical industry, the highest priority should be given by the Government of India to evolve policy framework, particularly focusing on the following aspects.
  • Firm and clear incentives should be extended to encourage chemical industry to implement programmes that would optimize the energy consumption in process operations
  • The industry should be encouraged to invest more time and resources in quality optimization programme and application development efforts to effectively compete in international market. The Indian industries should be persuaded to produce more grades and specifications of the products to enlarge the demand base and enter the export market in a big way.
  • There are huge number of educational institutions at higher level in India, who have invested enormous money in creating facilities for research and development, but they are not able to use the facilities adequately due to want of projects, programmes and assignments.
  • There is great urgency to encourage cooperation between the industries and  educational institutions to augment research and development efforts, so as to fully utilize the facilities and talent available in educational institutions and pool the resources for the larger good.
  • It is necessary to take some tangible steps to improve the quality content and depth of education provided to the university students in the subjects of chemistry, chemical Technology , chemical Engineering and related fields, so that there would be huge pool of talented technocrats available for chemical industry in future. There is crisis of talent in the chemical industry in India and it would be appropriate to recognize such inadequacies and initiate measures to overcome the problems.
  • A task force must be immediately constituted to precisely identify the areas that provide challenges and opportunities The Task Force should be asked to provide guidelines with regard to the areas of investments in future. Indian entrepreneurs should be guided to identify the appropriate areas for investment in tune with the strength of the country, over all policy approaches of the Government of India and needs of the country and in terms of availability of raw materials, size, market opportunities and geographical conditions and climate of different regions in India.
  • It is high time that the chemical industry should realize that there is no need to produce every type of chemical product and the product for production should be carefully chosen in tune with the national priorities. The “make or buy decision” for Indian chemical industry is now a matter of highest priority.
  • Massive investments have been made by the Government of India in setting up chain of research laboratories under the Council of Scientific and Industrial Research (CSIR) Unfortunately, such research laboratories have not been able to provide benefits commensurate with investment made.
  • Obviously, there is inadequacy in management of these institutions. Government of India should examine the feasibility of privatizing some of the CSIR labs or converting them into joint ventures with the Indian project promoters or international organizations.
  • Unfortunately, in the last few years jatropha biodiesel industry has not been able to progress to the expected and desired level. This has been mainly due to the lack of clarity in Government of India about extending subsidy support to jatropha biodiesel industry.
  • Government of India should not relax in promoting jatropha biodiesel as an alternative and appropriate energy source even though the crude oil price has come down in recent times. Government of India has to find permanent solution to reduce Indian dependence on international crude supply and ensure that India would not be vulnerable to the wide price fluctuations in the international crude price.
Characteristics Molecular formula C2H11NO2S Appearance DL-Methionine is in the form of platelets CAS No. DL-Methionine 59-51-8
L-Methionine 63-68-3
D-Methionine 348-67-4
Principal forms Methionine is produced in two principal forms as given below.
  • DL-Methionine (DLM)
  • Methionine Hydroxy Analogue (MHA)
DL-methionine is in the form of powder and is used for feed application Specification Description Details/Value Appearance White crystalline powder Assay 99% Ash 0.50% max Loss on drying 0.30% max. Bulk density 670 kg/m3 ± 10% Angle of repose 43° ± 10% Particle size distribution min. 90% 0-500μm Solubility: approx 48 gams per litre, water at 25°C * Methionine Hydroxy Analogue (MHA). Methinine hydroxyl analogue is a liquid source of methionine and it is used by feed millers for incorporating supplemental methionine direct into feeds. Methionine Hydroxy Analogue is produced in liquid form with a nominal 88% activity content. It differs from DL-Methionine by virtue of a hydroxy group on the alpha carbon, where DL-Methionine carries an amino group.

Dehydrogenation of ethyl benzene to styrene is a well established technology with continuing refinement of catalysts and reactor designs, so as to increase ethyl benzene (EB) conversion without losing selectivity to styrene The major licensors of EB technologies include: Lummus Technology with its EB One TM process and Badger Licensing LLC with its ExxonMobil/Badger EB Max process. The various processes are generally quite similar and the main distinguishing factors are the catalysts used in the alkylation and transalkylation reactions and the specific operating conditions throughout the processes. This article contains the following process details :
  • Lummus/UOP process
  • TOTAL/Badger styrene process:
  • Propylene Oxide/Styrene Monomer (POSM) Co-product Process
  • Process developed by Snamprogetti and Dow
  • New route based on methanol and toluene
Among all fats and oils, castor is the only one having a high proportion of ricinoleic fatty acid, a hydroxy fatty acid that is highly valued within  the chemical industry. Applications that are being developed for castor oil include base oil for lubricants, functional fluids and process oils; feedstock for fuels and oleochemicals; and a reactive component for paints, coatings and inks, and polymers and foams. Castor oil could now be used for the first time as polyol raw material because a special catalyst made it possible to avoid the formation of side products with bad odor. Previous attempts to manufacture polyetherols using renewable materials such as rapeseed, sunflower or olive oil have not been successful because of their odor and emissions levels. There were also disadvantages when it came to processing. This article contains the following details :
Pressed by margin shrinkage and environmental considerations to streamline costs and reduce environmental damage, many companies in chemicals and consumer products are developing applications for microreactors. Some companies are already using them for production. Microreactors are not a batch technology. Because they employ flow chemistry, a continuous process, the principles governing their operation and economics can be rewarding. Microreactors are even being developed for the production of bulk chemicals such as methanol and ethylene oxide (EO). A growing number of chemical manufacturers are trying to exploit the associated advantage of micro reactors. While a typical hydrocracking reactor might have a diameter of 4m, microreactor tubes range between 10 microns and 5mm. Because reactions in these narrow spaces tend to be extremely fast, the channels, as they are called, are also quite short. Issues related to mixing, heat transfer, mass transfer and hydrodynamics that slow transformations and allow side reactions in large reactors are effectively eliminated in microreactors, where mixing is essentially instantaneous. Reaction kinetics become the only limiting factor. This article further discusses the following details :
  • Advantages of micro reactors
