PETON COMPLETED WORK FOR UZBEKNEFTEGAZ

2021-09-21

Technological Engineering Holding PETON has executed the Project “Revamp of Existing UPPBS-3/Trains 1,2,5 for Shurtanneftegaz LLC”.

To increase production of liquefied gas, JSC Uzbekneftegaz decided at Shurtan Oil&Gas Production Department to revamp the existing propane-butane mixture preparation units (UPPBS)-3/Trains 1,2,5.

Under the Project, PETON has performed selection of internal contact devices, development of detailed engineering documentation, fabrication, supply and installation supervision of internal devices for K-1 rectification column. PETON crossflow packing units were manufactured and supplied for columns of all three units.

Project execution time - 2 years.

The units at which the work was carried out are intended for deeper complex processing of gas from the Shurtan field. The purpose of processing is to extract a propane-butane mixture from natural gas for use as household and motor fuel.

The process of recovering a propane-butane mixture from natural gas is continuous, performed by cooling and partial condensation of natural gas due to the effect of expansion of feed gas in a turbo expander with subsequent rectification of recovered condensate.

The rectification column for which the PETON packing was designed and supplied, is designed to separate light hydrocarbons to their residual content in the bottom product, which ensures the required quality of the propane-butane mixture.

Following the results of the column start-up, the management of Uzbekneftegaz noted a high level of the work carried out by PETON and confirmed that all the goals set within the revamp work had been achieved.

This is not the first project of this kind executed by PETON. The Company has implemented similar projects for Shurtanneftegaz, JSC Uzbekneftegaz, as well as at Yuzhno-Balyk GPP for SIBUR.
