Mounting of the hot high pressure separator was performed at the construction site of the combined hydrocracking installation of the TANECO Oil Refining and Petrochemical Plants Complex. This is already the fourth unit of heavy weight equipment mounted during the last month at this facility. The cold high pressure separator, the circulating gas absorber and the circulating gas compressor separator had been installed earlier.

The mounting of two separators weighing 240 and 111.5 tons, respectively, and the 385 tons absorber, manufactured by Mangiarotti S.P.A. (Italy), was preceded by a huge amount of preparatory work. The planned area for setting the cranes had been two meters below the metal structures, where according to the project it was necessary to install the production equipment. Mammoet Company had elaborated a plan to expand the site with increased load-bearing characteristics, which had to bear the weight of cranes and the equipment to be mounted with the total weight of more than 2.5 thousand tons. This work had been performed by OAO TATNEFT and OOO "Neftegasengineering" with good quality and on time.

Two Mammoet cranes of 1,350 tons and 500 tons capacity as well as specialized auxiliary machinery were used for assembling the heavy equipment. The equipment lifting was carried out by experts of Mammoet and Unix companies, which both had approved themselves in carrying out lifting operations and mechanical mounting works.

The complexity of the operation was that the vessels had to be lifted above the 24 meter datum mark and carried over the already mounted process rack. Following this the specialists mounted the equipment inside the existing metal structures of the amine treatment block for hydrogen containing gas, the technological rack of the gas compressing battery and the reaction products cooling and separation unit.

Lifting of the heavy equipment was performed in a regular mode, as the project of the works performance had been developed in detail with description of each operation sequence and the described processes were strictly followed by the experts of mounting organizations and the Department of implementing the construction project of the combined hydrocracking installation of OAO TATNEFT.

Information Reference

Full-scale works on construction of Phase 1B facilities of the NPiNHZ Complex in Nizhnekamsk have been carried by TATNEFT Company since 2011 concurrently with completion of Phase 1A1 facilities construction.

The combined hydrocracking unit, which will be incorporated into the process of the TANECO NPiNHZ Complex and has been designed to process up to 2.9 million tons of vacuum gas oil per year consists of two hydrogen production sections (3110, 3100), a hydrocracking section (4100), an oil production section (4600) and a section of hydrogen purification and concentration (3120). It will allow for increasing the yield of light oil and high-quality commercial products through processing of vacuum gas oil produced by CDU/VDU.
