I attended the AGM this year. An old gentleman spoke at the meeting (and I’m sorry I wasn’t paying attention when he spoke), but a book was circulating in the first few rows soon after called ‘A Practical Guide to the Manufacture of Sulfuric Acid, Oleums, and Sulfonating Agents’ available here.
I remember now that the old gentleman went back to the dias to greet Mr. Bimal Goculdas and asked him to use the new technology of cold process to make sulphuric acid, which I now find has been patented by Mr. Navin Ashar (also author of the aforementioned book). So I strongly believe that the old man was Mr. Ashar himself. Mr. Ashar had written some other books on sulphur chemistry also in the last 5 years
A search on his paper on cold process available here shows his bio -
“Intentional Wisdom” has been the guiding principle for over 150
years at MIT, Cambridge, USA. The author completed his Postgraduation
in Chemical Engineering at MIT in 1958, taking MIT’s
guiding principle to heart. On his return to India in 1961, after
serving as a faculty member at MIT, joined M/s. Dharamsi Morarji
Chemical Company Ltd. (DMCC).
DMCC produced phosphatic fertilisers requiring Sulphuric Acid.
From a modest beginning of an SCSA 50 TPD Sulphuric Acid plant,
over the period of 27 years, DMCC designed and operated a DCDA
800 TPD plant, which was a considerable achievement. On retirement
from DMCC in 1987, the author founded an innovative consultancy
company namely Navdeep Enviro and Technical Services Pvt. Ltd.
(NEAT) as Managing Director. Over the past 30 years, NEAT has
undertaken more than 100 projects in the manufacture of Sulphuric
Acid and Sulphonating agents, which have been cost effective and
The same paper was presented internationally in Aug 2018 at the International Conference on Petroleum Engineering in Dubai.
So cool to know that there are such wise old-hats associated with DMCC who are still working on bringing efficiency to sulphur chemistry.
