L&T builds among world's largest FCC regenerators, combustors

The equipment is considered the heart of the RPL''s refinery, billed as the fifth largest in the world. L&T had previously built a similar FCC regenerator and combustor for Reliance Industries Ltd''s (RIL) refinery in Jamnagar in 1998.

With the completion of the current project, L&T''s heavy engineering division has successfully constructed the most critical components of RPL''s Jamnagar complex, which is the world''s single largest refinery complex in the world.

xCcompleted six weeks ahead of schedule, the project was a repeat order for L&T by Reliance for the Jamnagar Export Refinery Project (JERP).

The main features of FCC regenerator and combustor are a 16.3 metre diameter, an overall length of 40 metres and weight of 1320 MT, made of carbon-manganese steel with more than 170 MT of stainless steel internals.

The process licensor for this equipment is UOP-USA, Mechanical Design (including the critical finite element analysis), detailed engineering and fabrication were done by L&T''s heavy engineering division at Hazira.

Incidentally, the company''s Hazira works is in the final stage of its capacity expansion project with which the shop capacity will double and include a super-heavy bay which can handle 2000 MT plus weight equipment.
