Editorial

While the traffic to MRC’s website continues to grow at a healthy pace, the same unfortunately cannot be said about the members’ general enthusiasm as evident by the poor attendance at our programmes. The response to my appeal 2 months back to furnish data for compiling a Members Directory has been rather dismal, with the figure so far not even touching double digits. Increasing the membership base and sustaining the interest of the existing members are the two primary challenges before our organisation. A variety of programmes have been lined up in the months ahead and we look forward to a more active participation by our members.

With the New Year just a few weeks away, I urge upon each one of you to include the following in your New Year Resolutions and more importantly act upon it

  1. To bring in at least one new member during the year
  2. Furnish your particulars for the Members Directory, especially your e-mail address
  3. Attend atleast one of the three programmes lined up between Dec 26th 2002 to Jan 29th 2003.

The initiatives of Website and monthly Newsletters have streamlined the communication. But in order that this process does not remain one-sided, readers are requested to write in with any useful bit of information, which they would like to share with their fellow members. It could be a useful tip, a solution to a problem or even posing a tricky problem. But no advertisements please! You can e-mail me at secretary@iichemrc.org, keeping the write-up to within 250 words. I look forward to hearing from you.

Chairman’s Message

The Honorable Petroleum Minister of India is active in introducing Alcohol in Petrol. In Phase 1 the Government notified sale of petrol blended with 5% Ethanol from January 1, 2003 in the nine major sugarcane growing states. In Phase 2, Petrol blended with 5% Ethanol will be supplied all over the country from September 2003. In Phase 3, percentage of Ethanol would be raised from 5% to 10%. The above approach is going to create a spurt in consumption of Ethanol from 2003 onwards. The price of Ethanol available to industry manufacturing Alco Chemicals like Ethylene, acetic acid, Ethylene Glycol, etc., is going to increase. This may create a downward journey for the Alco Chemical Industry as they will find it difficult to compete with petroleum based products. Already some of the large Alco Chemical units are closed. Above is going to create problems for the Alco Chemical industry unless they have their own Captive Alcohol manufacturing units.

At the same time Indian petroleum refining industry spearheaded by Indian Oil is executing the projects on Lumpsum Turnkey basis as compared to the conventional EPC routeduring earlier days. The entire Panipat Refinery, which was engineered indigenously, is now being expanded through LSTK mode. The contractors are generally Koreans and in some cases L&T. When the Korean Contracting organizations win the Lumpsum Turnkey award, the engineering of these projects is being done in Korea whereas same could have been done in India, by the local engineering contractors. On one hand the foreign exchange is being paid for the engineering services as part of the Lumpsum Turnkey Contract whereas Indian Engineering Contractors in Process Industry having more than 10,000 people are struggling for getting proper projects as the investment scenario in India is pretty dismal. Lumpsum Turnkey mode of execution drives the project to a higher Capital Cost as compared to conventional EPC mode of execution. Thus the authorities need to look in to the mode of execution of these projects so that Indian Engineering Contractors can survive. In countries like Malaysia, China, Iran, etc. the Detailed Engineering for all projects not withstanding the mode of implementation is required to be carried out by local engineering contractors. Why not in India?

Lecture on ‘Implications of WTO for Indian Chemical Industry’

by Raghav Narsalay

Mr.Raghav Narsalay, a consulting economist and a leading expert on WTO related matters delivered an interesting lecture on the above topic at UICT on Nov.22nd. A summary of his lecture follows.

The objective of most businesses today is to produce a globally competitive product / service and make profits. This essentially depends on the costs associated with Raw Materials and Technology, value as well as volumes of concerned products at various levels and the performance of the industry internationally.

Factors which affect global competitiveness


Report on Seminar

Distillation Technology- Principles and Practice

28th September 2002 at UICT, Matunga, Mumbai

AMIC together with Indian Institute of Chemical Engineers (IIChE, Mumbai Regional Center) organised this seminar on 28th September 2002. Over 100 delegates attended the seminar from Industry and Academia. The large number of attendance showed the keen interest of practicing Chemical Engineers from both industry and academia due to a very popular topic "Distillation Technology". Dr. P. S. Ramanathan, the founder President of AMIC explained the need for the establishment of AMIC and focused upon the role it can play in the amalgamation of Chemical Engineering profession and Chemistry related activities. Dr. Ramanathan amply illustrated the main objective of continuous sharpening of skills in Chemistry and Chemical Engineering to improve the educational and industrial awareness in the competitive economy.

Professor V. G. Pangarkar, Head, Chemical Engineering Division, UICT, gave the inaugural keynote lecture titled "Distillation- An Art or Science". He dwelt at length on features of Packed and Tray distillation columns. He gave detailed design considerations in the selection of column components/internals such as downcomers, structured and random packings. He also stressed upon the important role of liquid distributors in structured and random packed columns.

The talk on "Structured and Random Packings" by three experts from Sulzer India Limited described the evolution of structured and random packings over the years since 1940’s. They gave the relative importance of various types of packings such as wire gauze, corrugated structured packings like Mellapak, Gempack, etc. Their talk also touched upon the column sizing and comparison of structured verses random packings. They also showed case studies including the retrofitting the old distillation column with newer packings. Notably, they gave an example of Ethyl Benzene/Styrene system where it was shown that the replacement of trays with Mellapak could give higher capacity, better turndown ratio and higher efficiency as compared to the earlier design. Natural gas drying using triethylene glycol was another tested system, according to Mr. B. Balaji of Sulzer India Limited.

Mr. Vishwas Dabholkar from Jacobs H & G illustrated the selection procedure for column internals with advanced trays like superfrac/Minivalve trays, Maxfrac/Bifrac trays, Triton Trays etc. and the relevance of these new tray designs to optimize the tray spacings, perforation size and downcomer/active area distribution. A comparison of high performance trays vis-à-vis structured packings was also deliberated during the seminar. The criteria for selection of internals was elaborated with reference to process features and performance enhancement. The logic of choosing between structured packing and high performance trays for distillation retrofits was explained in lengths with schematic presentation.

Professor K. P. Madhavan, Professor of Chemical Engineering from Indian Institute of Technology spoke on role of Instrumentation and Controls in today’s distillation columns. He emphasized on the role of operating variables on column performance. A highly illustrated lecture gave the audience various possible approaches for optimizing the column performance. Measurement of key variables with profit optimization and predictive control model were lucidly explained with control diagrams.

Mr. Raosaheb N. Patil, Managing Director of Technoforce India Ltd. spoke on High Vacuum distillation of Heat sensitive materials. A stepwise procedure to understand the advantages of Agitated Thin Film Evaporator in terms of increased average velocity or reduced residence time, leading to increased heat transfer rates was explained in a simple but effective way. Use of thin film evaporator as a reboiler for separating close boiling liquids and the use of short path distillation were discussed. The need to overcome the pressure drop associated with Agitated Thin Film Evaporator was also discussed. Dr. D. D. Ravetkar, Scientist, NCL, Pune shared his long experience in troubleshooting and design of distillation columns. He is popularly known for his DDR approach - Distillation, Designing and Revamping.

The seminar concluded by Professor R. K. Malik, Head, Chemical Engineering Department, IIT. He summarized the importance of the subject and shared his long experience of troubleshooting the Industrial Distillation columns with the participants.
