In the early part of 2000, Raffineria Di Milazzo S.p.A. (a joint enterprise between Agip Petroli and Kuwait Petroleum), decided to award two contracts, together price about $34 million, for its refinery in Milazzo, Sicily.
The plant was originally purely an Agip facility, and has been in place for many years. The brand new undertaking is an addition to the already extensive range of gear put in at the refinery.
The overall undertaking has two important contracts each of which were awarded to Technip, an organization with longstanding experience of the Italian market. The primary contract issues the construction of a new hydrodesulfurisation unit and the second issues the upgrading of the prevailing vacuum distillation unit.
THE HYDRODESULFURISATION UNIT
The hydrodesulfurisation unit undertaking includes a brand new 6,800 tons/day gasoline oil hydrodesulfurisation unit as its most outstanding element. the brand new unit is predicated on high-stress know-how. This lead contract additionally encompasses the upgrading of an amine unit and the event of a distributed management system that interconnects the refinery.
CRUDE VACUUM DISTILLATION UNIT
The present crude vacuum distillation unit is being upgraded so as to scale back sulphur content in emissions.
Eradicating sulphur is an important a part of refining, not solely due to its value as a product in itself but additionally as a result of current environmental laws implies that European and North American nations are actively promoting low sulphur fuels. The EU has recently launched new requirements for desulphurised gasoil which the Milazzo modifications are designed to meet. The Raffineria Di Milazzo is additional concerned with its own sulphurous emissions, hence the second lead contract.
The lump sum turnkey contracts, which will be handled by Technip teams based in Rome, cover detailed engineering, procurement, development, pre-commissioning and coaching for the initiatives. Work is scheduled to be completed in spring 2001.
LIQUID PETROLEUM Gas (LPG) STORAGE PLANT
In 2000, the refinery saw another incremental addition because it gained an LPG storage plant. The lead contractor for this small venture was Snamprogetti. The technology for the security system was equipped by ICS Triplex, which put in its Trusted brand of triple modular redundant (TMR) techniques. That is designed to offer each Emergency Shut Down (ESD) and Fireplace & Gasoline (F&G) detection from one system.
At Milazzo the ESD/F&G system is related to a 600i/o Distributed Management System (DCS) and to the Uninterruptible Power Supply (UPS), which was also installed by ICS Triplex. The management cabinets for all three systems are situated in a ‘technical room’ and so they communicate by way of a co-axial cable network with the distant predominant control room positioned 600 metres away as a security precaution.
