OREANDA-NEWS. On 6 February 2008 OMZ (Uralmash-Izhora Group) announced the completion of a test run of the first hydrocracking reactor shell produced by OMZ for TANEKO OJSC. The test run was conducted under an agreement concluded in August 2007. The agreement provides for the production and supply of two reactors for a newly built complex for fine oil processing in the city of Nizhnekamsk.

For the first time OMZ used chrome-vanadium-molybdenum steel SA 336 F22V with a 2.25Cr-1Mo-0.25V alloying system. This steel’s production is very complicated as the requirements of its chemical composition and its mechanical and other characteristics are highly demanding. The process of metal smelting includes vacuum carbon deoxidation, microalloying, and modification through the addition of niobium and calcium. The permissible level of detrimental impurities can be up to the thousandth of one percent.

The test run for the shell made from a 235-ton ingot was completed on 31 January, 2008. Metal durability and flow, its extension and contraction and other characteristics were within normal limits. Strict requirements on heat and cold resistance under +454оС and –18о and –34о С were also fulfilled.

Technical design of the reactors was developed by the Moscow Scientific and Research Institute for Petrochemical Engineering (VNIINeftemash) on the basis of a specification by Chevron Lummus Global LLC, one of the leading international licensers.

In August 2007, OMZ won an international tender for the manufacture of two hydrocracking reactors for TANEKO (TATNEFT Joint-Stock Company), a newly built complex for fine oil processing in the city of Nizhnekamsk. The contract’s value exceeds RUR 1.5 billion. The reactors are to be manufactured and shipped by OMZ in August and October 2009.

This equipment is unique in its dimensions, weight characteristics, quality and characteristics of the metal and welded joints made from 2.25Cr-1Mo-0.25V steel.
