Thank you for understanding and we wish you Merry Christmas and Happy New year 2022.


International Engineering Fair Brno 2021

The company UNIS participated in the 62nd International Engineering Fair in Brno, Czech Republic, which took place from 08th to 12th November 2021.

The exposition covered all our activities mainly the full range of engineering services related to high-investment equipment (EPC/EPC-M), design and application of process control focus on the petrochemical, oil refining and power generation industries. Production of electronics for aircraft and automotive industry, high-power electronics, manufacturing execution system MES PHARIS®, Test laboratory, IoT and new area Waste processing line. Thank you for your visit.



The hydrocracking complex or implementation of the hydrocracking process (HVGO) of heavy vacuum gas oil is focused on obtaining light petroleum products (gasoline and diesel).

The contract followed the construction of this unit carried out in the years 2002 - 2004. Thanks to the "Hydrokrak", the Naftan refinery acquired a unique product - diesel fuel meeting the Euro-5 standard. In 15 years, more than 7 million tons of diesel have been produced here by the hydrocracking process. The just completed second phase of the reconstruction will increase the capacity of the hydrocracker by 25%, ie from the original capacity of 112,5 t / h of processed heavy vacuum gas oil to 142,2 t / h. UNIS acted as a general contractor and designer, ensured the preparation of engineering research, processed design documentation, mediated the supply of technological equipment and materials and, last but not least, organized author's supervision and supervision within the assembly and commissioning. After successful start-up and reaching the parameters, the unit is now in trial operation.

In addition to increasing the production of diesel and kerosene, it will be possible to process a completely new raw material in the complex's facilities - heavy vacuum gas oil from a delayed coking unit. And high-quality by-products such as hydrogenated refined residues for paraffin oil production, base lubricating oil components, liquefied petroleum gas and gasoline will continue to be provided in large quantities.


Process units NHT and CCR

Commercial Director of UNIS Mr. Ladislav Čapka is pleased to announce that after three years of efforts our company has succeeded in the tender and received an award for the EPC project for the implementation of two process units Naphtha Hydrotreating Unit (NHT) and Continuos Catalytic Reforming (CCR) including the necessary auxiliary offsites&utilities and building facilities in the amount of more than 6 billion Czech crowns for the Iraqi customer SRC Basrah Refinery. For the main process, the licensor Axens Solutions, France, is assumed. The works are expected to start in early 2022. The implementation of the works is scheduled for 4 years and successful guarantee tests.



There is one important point in the technological chain for the production of refinery coke (DCU), which will provide the Naftan refinery in Novopolotsk with the production of liquefied petroleum gas (LPG). It is a unit for purification of liquefied hydrocarbon gases DCU from mercaptans (active sulfur compounds) MEROX. In a liquefied hydrocarbon gas, the mercaptan compounds are methyl and ethyl mercaptan (CH3SH and C2H5SH). Because mercaptans are highly corrosive compounds, they must be removed from the process or converted to other organic compounds.

During the implementation of the project, UNIS, a.s. provided comprehensive engineering research, processed project documentation (architectural and construction project), including obtaining the consent of the state expertise. It also supplied all the necessary equipment and materials and also provided chief assembly and author supervision services during construction and commissioning.

The "Merox" unit is currently undergoing a comprehensive testing phase with a replacement medium. In cooperation with the employees of the end customer, the launch for the guaranteed performance of the design capacity of the unit, which is 19.61 m3 / h (96 thousand tons per year) of liquefied petroleum gas (LPG) as the main product of this unit, is being prepared.

The final commissioning of the Merox unit is scheduled for the end of 2021.

Ecological processing of waste material

UNIS has started cooperation with SmartTechnik a.s. on deliveries of Waste Processing Lines. The production technology is designed for the ecological processing of waste material into building material based on the physical and chemical properties of the material. UNIS provides its own part of the control system and power supply for the line.

Part of the extensive modernization of the Novoshakhtinsk refinery in the Rostov region of the Russian Federation is the construction of a complex for the production of AI-92 and AI-95 Euro-5 petrol.

UNIS, a.s. contributed to this stage by supervising the elaboration of the licensing documentation and its subsequent elaboration into the documentation of the initial project (Proektnaja Dokumentacyja), including obtaining the consent of the environmental and state expertise. The documentation was incorporated for technological units: Naphtha Hydrotreater - NHT, Continuous Catalytic Reforming - CCR, Isomerization - Penex and for auxiliary units - nitrogen station, boiler room, laboratory, office building, central control room building, power supply node and flare system. It also provided customer support in the purchase of equipment, in the form of processing inquiry requisitions. The technological licensor was the company UOP. Completion and handover of the design documentation took place on 15.02.2021. The documentation received a positive opinion of the Russian state expertise № 61-1-1-3-045373-2021. Based on the opinion, a building permit was issued and preparatory and construction work is currently underway.

Upon completion, the Novoshakhtinsk refinery complex will offer approximately 717,000 tons of gasoline of the 92, 95 Euro-5 class and approximately 2 million tons of diesel fuel per year.


Spare parts for Basra refinery, Iraq

Commercial Director of company UNIS Mr. Ladislav Capka dares to announce, that at the end of 2020, despite a more complicated coronavirus crisis, succeeded in tender and sign a contract for delivery of spare parts in amount of a quarter of a billion Czech crowns. Spare parts are intended for units Naphtha Hydrotreater and Semi-regenerative Reforming of the SRC Basrah refinery, Iraq, which were successfully implemented and started up by company UNIS in 2015.
