At the heart of the GTL process

GTL technology involves conversion of methane to high molecular weight hydrocarbons from LPG to waxy paraffins. The process itself consists of mainly 3 steps, syngas production through steam reforming or partial oxidation, liquid production through Fischer-Tropsch (F-T) reactions with cobalt or iron-based catalyst followed by product updgrading through mild hydrocracking to convert high molecular weight waxes to LPG, naphta and diesel.

Determining the control valve pressure drop for control valve sizing purposes

Our guest writer Jon F. Monsen discusses the correct method for determining the control valve sizing pressure drop when the system already exists or has been designed.

2 proven options to secure process availability

The safety valve is the final element in the safety loop. It operates in the most challenging environmental conditions and is constantly in contact with process media in the pipelines.
