Croatian refinery due processing unit

Croatia’s INA Industrija Nafte DD, Zagreb, has let a contract to Duro Dakovic Industrijska Rjesenja DD, a subsidiary of Djuro Djakovic Holding DD, to supply equipment for a processing unit to be installed at its 4.5 million-tonne/year refinery along the northern part of the Adriatic Sea at Urinj, Rijeka province, Croatia.

As part of the contract’s work scope, Duro Dakovic will build and deliver two columns for an LPG amine treatment unit to be built at the refinery, the service provider said in a Feb. 15 filing to Zagreb Stock Exchange.

Valued at about 4.56 million kuna ($670,000), the contract also includes delivery of spare equipment parts, as well as technical services involving design and development of technical documentation for the plant, Duro Dakovic said.

While the service company identified a 2-year duration period for its work on the project, it disclosed no further details regarding planned unit.

Last year, INA held a tender scheduled to close on Sept. 28, 2015, to invite bids from suppliers for delivery of pressure equipment including heat exchangers, vessels, and columns for the Rijeka amine unit installation, according to a tender notice issued on Aug. 31, 2015.

The Croatian refiner also was inviting bids for manufacture and delivery of chemical injection packages for the LPG amine treater in a tender scheduled to end on Oct. 21, 2015, according to a Sept. 29, 2015, invitation to bidders.

INA previously announced it is executing a more than $400-million residue upgrade program at Rijeka to improve the refinery’s market competitiveness by increasing conversion of the site’s existing production to lighter, more valuable products such as LPG, gasoline, and diesel (OGJ Online, July 7, 2015).

The residue upgrade project at Rijeka comes in the wake of a series of modernization efforts INA has undertaken at its two Croatian refineries over the last few years, all of which aim to boost the refineries’ profitability and environmental competitiveness by increasing production of cleaner, higher-value products while simultaneously reducing harmful emissions.

As of May 2011, INA had commissioned three units within the Rijeka refinery’s hydrocracking complex, including a mild hydrocracking unit, hydrogen unit, and Claus sulfur recovery unit.

At INA’s 2.2 million-tpy refinery in Sisak, Croatia, 30 miles south of Zagreb, the company has invested more than $170 million to construct processing units, including a $5-million replacement of coke chambers in April, all designed to improve crude processing efficiency as well as enable production of petroleum products that meet Euro 5 quality standards (OGJ Online, Sept. 19, 2014).
