Reliance Petroleum has ordered a Rotoform sulphur pastillation plant from Sandvik Process Systems for its Jamnagar refinery complex in Gujarat, India. Sandvik will supply 8 Rotoform HS (high speed) steel-belt-based pastillators, plus conveying, storage and loading facilities. Start-up is scheduled for February 2008. Rotoform HS provides twice the capacity of the Rotoform 3000 pastillator on which it is based. The key improvement is an increase in the diameter of the “shell” that deposits the molten sulphur on the belt from 80mm to 250mm. By reducing the centrifugal force on the droplets, this allows the Rotoform HS to run at higher speeds while still delivering well-shaped pastilles. Other key features of the Rotoform HS are the ability to deliver product conforming to the widely-accepted Sulphur Development Institute of Canada specification, low hydrogen sulfide emissions, and a low offloading temperature for the solidified sulfur.kem.
