Launching innovative products for customers is in our DNA

Antti Nelimarkka’s 1973 valve design allowed valves to be more reliable than ever before. He designed a metallic seat ring instead of a rubber one, and the world’s first metal-seated butterfly valve was born, setting the industry standard. Neles has since built itself around innovation and significant breakthroughs to provide our customers with more reliable and safe products – it’s in our DNA.

Upgrading FCC-unit valve controllers without disruption

In the fluid catalytic cracking (FCC) unit of a large refinery built in the 1940s in the US, a variety of control valve types and brands, along with their proprietary valve controllers, had been installed over the years. This had led to production inconsistency and disruption. The unit wanted to have one type of controller with multiple bracket designs to fit the wide variety of valves in the plant.

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.
