Uzbekneftegaz selects Axens’ advanced technologies for production of Euro V gasoline at Bukhara refinery

Axens has been awarded by Uzbekneftegaz, the Uzbekistan’s state-owned oil and gas company, a Basic Engineering and License contract for the modernization project of Bukhara Oil Refinery. The target of this project is to enable the production of Euro 5 gasoline in compliance with the highest international standards.
As a major licensor in the refining field, Axens has long-standing partnership with Uzbekneftegaz,
accompanying Bukhara Oil Refinery with technical services and catalyst supply for the optimum operation of the plants since the first process units licensed by Axens’ were put in operation in 1997.

Testimony - The start-up went very smoothly in 2019

The start-up went very smoothly in 2019, even when the feed flowrate fluctuated between 65% to 105% of the design flowrate. Axens process design is quite robust to face possible start-up and operating troubles.

Testimony - The start-up went very smoothly in 2019

The start-up went very smoothly in 2019, even when the feed flowrate fluctuated between 65% to 105% of the design flowrate. Axens process design is quite robust to face possible start-up and operating troubles. After a week of operation the temperatures were adjusted as per design to 113°C and 120°C for First and Second Reactors respectively. The isomerate RON was above 88, up to 89.2 sometimes, according to our laboratory.

HCl Absorber efficiency was high. C2Cl4 injection was gradually decreased to minimum recommended ratio of Cl/feed but HCl concentration detected in Stabilizer off-gas was still above 5000 ppm. 

Currently we are still very satisfied with Axens ISOM technology and ATIS-2L catalyst. Thanks to the HCl recovery innovation we save 75% of chemicals, and earn 1% isomerate yield more.
