P 105 Liquid Cryogenic C2 Transportation

P 105


Liquid Cryogenic  C2 Transportation

In 1991-92, I had the honor to execute the first double walled cryogenic Ethylene tank terminal facilities at Hazira. But in late 2013,PX IV at JMD was looking for cryogenic Ethylene availability for their compressor duty as refrigerant media and the PMT (Project management Team) and the concerned DECs  were going around without coming to any concrete methodology! Especially M/S Fluor HSE personnel were exploring the possibility of accommodating two horton spheres in the available cramped space. Specially C2 being one of the challenging cryogenic medium, the wall thickness for sphere was crazy and LEL distance was hitting the nearby sub-station in PX B/L. So the possibility of creating any storage at South corridor got ruled out.

Then only they posed the issue to my attention and also asked whether we can utilize ISO container to transport the C2 through National Hi-way and can we get PESO permission and licence for transportation ! As that was the time I used to give consultancy to the PESO department, I knew that methodology was not at all acceptable statutorily especially in Indian roads. When I ruled it out, people around criticized me and commented. Moreover, one set of team strongly vouched that we should bring the Cryogenic C2 from our Nagothane plant area only since it had the loading infrastructure already. No one was ready to look into the involved challenges:- involved transportation distance of 1000+ KMs. one way, involvement of two different state authorities enroute, number of toll posts, local political issues at Raigad District and availability of suitable transport media etc.
The specialist team of RTG discouraged me to consider Hazira facilities for sourcing cryogenic C2
because of cramped movement space at Hazira.  That made me to consider  DMD-Dahej as the probable sourcing point .As such VMD do not have cryogenic storage for ethylene at all.

As luck would have it, self & Sh.Samir Karnik  bumped on a LNG carrier parked at Dahej  main road opposite to DMD main gate. Seeing that , we jumped out of our car and got in touch with that truck driver to gather data about that vehicle &its specification etc.. He said that in India there are about 50-60 semi-trailers licensed by PESO for LNG movement across the country. He added that most of them are designed &fabricated indigenousky at IOC Workshop, Nashik. So our attention got shifted to Nashik. Meanwhile we thought it is better to seek the confidence of PESO department officials  for
going ahead with semi-trailer arrangement for cryogenic C2 transport in Indian roads, since there was no prior reference for that challenging service. In Jan.'15 I organised a presentation to the entire PESO department at Nagpur with our team .  I made sure that Reliance presentation address all aspects of safety assurance and the presentation went through very smooth ,more than anybody's expectation. Rather my team questioned me post meeting- sir, who is CCE in that gathering! The meeting went on for sharp 40 minutes and only 2 questions were tabled by authorities-1) considering the involved distance, with only day light driving, will consideration of one night halt enroute only be sufficient ? 2) in case of vacuum break in cryogenic tank , what will be the time estimate for the pressure build up to pop the safety relief valve?  Post meeting when I had a sitting with CCE- Mr.Thomas, he suggested to consider INOX favorably, since they had the experience to build Hydrogen containers for space crafts. That made my task even simpler.
