Capacity
The refinery had an original design capacity of 2.5 million metric tons per annum (mmtpa) which was increased to 3.3 mmtpa in 1973. Production of liquefied petroleum gas (LPG) and aviation turbine fuel (ATF) commenced after this expansion.
Refining capacity was further enhanced to 4.5 mmtpa in November 1984 when a fluidized catalytic cracking unit (FCCU) of 1 MMTPA capacity was added.
In Dec 1994, refining capacity was increased to 7.5 mmtpa (150,000 bpsd) along with revamp of FCCU to 1.4 MMTPA. A fuel gas de-sulphurisation unit was installed as part of this project to minimise sulphur dioxide emission. CRL entered into petrochemical sector in 1989 when aromatic production facilities with a design capacity of 87,200 tons per annum of benzene and 12,000 tons per annum of toluene was commissioned. In the year 2000, a 2 MMTPA Diesel Hydro De-sulphurisation (DHDS) plant was added to reduce the sulphur content in Diesel.
In August 2010, the refining capacity was further increased to 9.5 mmtpa (190,000 bpsd).
A captive power plant of 26.3 MW was commissioned in 1991. An additional captive power plant of 17.8 MW was commissioned in 1998 thus making the refinery self-sufficient in power.
An LPG bottling plant of capacity 44,000 TPA was commissioned in 2003. A Bitumen Emulsion plant of 10000 TPA capacity has also been commissioned in 2004.
A Biturox Bitumen Oxidation Unit of 378,000 TPA capacity was successfully commissioned and started-up in 2008.

Famous quotes containing the word capacity:
“For a transitory enchanted moment man must have held his breath in the presence of this continent, compelled into an aesthetic contemplation he neither understood nor desired, face to face for the last time in history with something commensurate to his capacity for wonder.”
—F. Scott Fitzgerald (1896–1940)
