Work safety interaction assessment of VOC’s emission under emergency work of IPPC installation

100%

Szatko W. , Wawszczak Ł.

The study evaluated the impact of emissions (VOCs) as a result of the operation of the printing of plant at working positions of those performing their tasks outdoors or in buildings next door. The first part of the paper presents the general characteristics of the process and materials used for printing. The further part shows the results of the modelling of emissions, depending on the operating state of purification (emission in normal conditions and emission in failure state of the afterburner).

Zur Modellierung des Flockungsprozesses im Rohrreaktor mit Querschnittsänderungen

80%

Dyląg M. , Rosiński J. , Szatko W.

In der Arbeit wurden die Grundlagen der Modellierung des Flockulationsprozesses formuliert und ausführlich diskutiert, wobei die hydrodynamischen Aspekte der Strömung im Rohrreaktor mit Querschnittsänderungen berücksichtigt worden sind.

Safety in subsea petroleum production systems: subsea christmas tree case study

80%

Adamowicz K. , Sarna P. , Szatko W.

The paper presents an analysis of valves used for closing and opening production tubing, located on the production line. The main safety valves analysed in this work are located in the Christmas Tree and in the Downhole Safety Valve. The analysis was conducted using FMEA; it found that for each basic Christmas Tree’s gate valve, the most dangerous failure modes are external leaks and “fail to close” in the open position of the valves. For the Downhole Safety Valve, the most dangerous fault can occur in the open position of the valve. The Downhole Safety Valve and the Christmas Tree complement each other, thus ensuring safety during oil and gas production.
