Identification of stabilizers from polyolefin samples by headspace GCMS (SIM) method

Plastics without additives are not viable. We can distinguish the main additives as follows: stabilizers, acid scavengers, slip additives, polymer processing aids, anti-blocking additives, antistatic additives, antimicrobials, flame retardants, chemical blowing agents, peroxides, colorants, optical whitening agents, fillers and reinforcements, nucleating agents, etc.

Function of geological study in Pakistan hydrocarbon research

As the subject of the Pakistan hydrocarbon project, there several exploring and producing wells have been drilled since 1999 by MOL Plc. and Partners. Geological study of the material of these drillings was mainly fulfilled by the geologist team of the Exploration and Production Division at Békásmegyer (HU). Our work is to examine the cuttings and core samples from petrographic and palaeontological point of view.

Compliance with future regulation of air quality management in refining

Meeting the increasing demand for motor fuels parallel with the more and more stringent environmental norms can only be accomplished by improving engine design in parallel with the development of motor fuels. This continuously forces refineries to invest into technological development projects and this, in turn, unavoidably entails the increased emission of air pollutants from the refineries.
