New marine horizons with LNG

Knutsen Group of Norway has started a new LNG marine project with Valmet. Knutsen is the world’s largest shuttle tanker operator and a major operator of LNG carriers. Their project, LNG/c Haugesund Knutsen, is a 5,000 m3 LNG bunker barge that will supply LNG to gas carriers and LNG-fueled vessels. The vessel is owned by Knutsen and will operate in the port basin of Barcelona rather than make long voyages.

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.

Asia’s largest biomass power plant operates with Valmet DNA

The Dangjin plant near Seoul in South Korea is the largest biomass power plant in Asia. It uses a mix of agricultural and associated by-products. The plant generates 105 MW electricity and the demanding process is run with Valmet’s latest technology, Valmet DNA.

Fugitive emission control creates site efficiency

From end-user point of view, perhaps even more important than the selected standards and simple compliance with ever-tightening environmental regulations, are the other benefits provided by the low fugitive emission valve designs.

Optimizing performance of Borås Energi and Miljö boiler by improving maintenance process, shut-down planning and digital support tools.

Collaboration with Borås Energi & Miljö in Sweden, the cooperation started during the take-over of the plant back in 2019. Through a Performance Agreement Valmet and Borås Energi & Miljö enable stable production by minimizing unforeseen shutdowns.

VacRoll suction holes and grooves should be cleaned regularly

VacRoll suction holes and the grooves of all rolls should be cleaned regularly, as they may get completely clogged due to web moisture, particularly at the start of the dryer section. Bearing housings also need attention. Proper handling of the rolls is also important.

Steam and condensate system performance - explanation and tips

The purpose of a paper machine steam and condensate system is to control steam pressures for optimum drying, provide stable control over the entire operating range and efficiently remove condensate from inside the dryers. This article presents tips for maintaining performance with your S&C systems.

New earnings with Valmet boilers

Many Japanese energy and paper producers have not only boosted their sustainability and energy efficiency but also found new ways to make money.
