The paper presents an examination of the general types and typical heat properties of the used plate heat exchangers in modern gas processing plants.More
Application assessment of membrane-based gas separation technology
A significant proportion of natural gas fields in production or in development held by MOL Plc. in and out of Hungary contain large quantities of inert gases in combination with methane as principal component.More
Hydrocyclone separation in oil industry – Part 2.
By the end of the last century the application of oil industry hydrocyclones had become common practice primarily in the field of crude oil production but the hydrocyclone separation technologies had appeared also in the refining processes.More
Steam-cracking of waste plastics to produce monomers
Thermal decomposition of different types of waste polyethylene (PE) and polypropylene (PP) is presented.More
Object-based modelling in a turbidite type reservoir
The three medium size turbidite systems (Földvár Felsô A-1, Földvár Felsô A-2, Földvár Felsô A-3), summarized as the Földvár gas reservoirs (Hungary), have been captured in a 3D geological model on the base of a layer cake modelling technique.More
The sand of time in the pump –
An introduction to a new type of tubing pump: Farr Plunger Plusz (B&Sz)
During the extraction of oil fields, numerous factors can worsen the efficiency of down hole pumping.More
Hydrocyclone separation in the oil industry – Part 1
The oldest traditional method employed in the oil industry for the separation of different fluid phases is settling.More
Laboratory modelling on enchanced gas and condensate recovery
Gas condensate fields produce gradually less condensate because of retrograde condensation when pressure drops beneath the dewpoint pressure.More
Integrated modelling of Pusztaföldvár Underground Gas Storage from reservoir to the surface
The objective of this article is to present a fully integrated model of an underground gas storage (UGS) field from the reservoir level up to the separator level.More
Killing two birds with one stone - Barlahida 3D seismic acquisition and processing
Ten years ago MOL E&P required a new 3D acquisition in the Zala area, Western Hungary.More
VGO hydrocracking plant reconstruction in Slovnaft Bratislava Refinery (BR)
In 2009, the Slovnaft Bratislava Refinery vacuum gas oil hydrocracking unit was revamped.More
Development of special polypropylene grade for spunbond application at Slovnaft Petrochemicals
The article provides a broad overview on global polypropylene fiber production and especially on market trends for nonwoven where polypropylene plays an important role.More
Installation of an electrostatic precipitator in the FCC plant of Duna Refinery (DR)
After the revamp of DR FCC unit in 2005 over the limit dust emission was measured in the flue gas of the unit.More
IT application

This article includes an overview of TVK quality improvement and the applied IT solutions, Lotus Notes applications and its
advantages.More
Possibilities for processing of used lubricating oils
In this paper the options of recycling of used lubricating oils including reprocessing, reclamation and rerefining are discussed.More
Experiences of the SIL project
Who has never heard the phrase ’this shutdown loop is SIL3’, but do we actually know what that phrase means? What does such a statement entail to MOL that an instrumented safety tasks should be compliant with SIL1, SIL2 or SIL3?More
Gas supply security or enhanced gas recovery?
In January 2006, a serious havaria situation emerged in the gas transmission of Central Europe due to the dispute between Ukraine and Russia leading to a shutdown of gas supplies.More
Transporting benzene and toluene by pipeline – First at MOL in the world
Start of TVK Olefin 1 unit in August 2003 and of the new Olfin-2 Plant in the following year has created a 710 kto/year transport demand increase between Százhalombatta and Tiszaújváros.More
Possibilities for processing for used lubricating oils – Part 1.
In this paper the necessity and importance of recycling of used motor oils are reviewed.More
Chemically stabilized rubber bitumens
It was proven that blending bitumen with crumb rubber, which is produced from scrap tires, is not just a waste treating method, but an excellent solution to improve the performance of asphalt pavements compared to roads made of conventional bitumen. The application of rubber bitumen is most widely spread in the US, where the production of the rubber modified binder is in situ, close to the road construction.More
Capture diesel growth opportunity in Danube Refinery – Hydrocracking Project Package
The emerging challenge for the EU refining industries is the rapidly growing diesel demand. While simply adding more distillation capacities could help to ease the diesel situation, such stand-alone solutions would, however, also result in higher motor gasoline output to an already long EU motor gasoline market.More
Ethylene Recovery from Ethyleneoxide Unit Offgases
This paper depicts one possibility how to increase the benefit at the Ethylene oxidation 2 unit in Bratislava Refinery. The refinery offgases can contain valuable components e.g. ethylene, propylene or hydrogen, which are used only as fuel gases. There are some possibilities, how to remove them from the offgas stream and use as important raw material.More
Examination of new turbo-feed pumps construction for Power Plant boilers
Unit P4.1 Power Plant is situated in Refinery Slovnaft Plc. Power Plant main task is supply superheated steam (pressure levels 0.4, 1.0 and 3.5 MPa) and electric power to Slovnaft refinery. High pressure superheated steam is produced on five high pressure steam boilers with installed load on 780 tonns per hour. Electric power is produced on four steam turbines with installed power 114 MWe.More
