CB&Is Lummus Technology business unit
successfully commissioned the delayed coking unit (DCU) for Essar
Oils Vadinar refinery expansion project in Gujarat, India, the companies said on
The Vadinar refinery increased its capacity to
20 million tpy or 405,000 bpd, up from 10.5 million tpy and
200,000 bpd previously.
The expansion and enhancements allow
Vadinar to process a much greater proportion of lower cost,
heavy and ultra-heavy crude oils.
Vadinar is the second largest, single-location refinery in
India and has increased from 6.1 to
11.8 on Nelsons complexity factor, including it among the
most complex refineries in the world.
The entire unit - constructed by Essar Projects (India) - was completed on
an EPC basis and took 30 months to commissioning.
The DCU - one of the largest in the world - enables the
Vadinar refinery to process challenging and
heavy crude slates by converting the residual oil from the
vacuum unit to higher value distillate products, such as
gasoline, diesel and heavy gas oil.
The solid petroleum coke by-product may also be used in the
cement industry or power generation.
Lummus Technology provided the basic
engineering, proprietary heater design and material supply,
pre-commissioning, commissioning, training and start-up
CB&Is project engineering and construction business performed the
