  • Fugitive emission certified valves enhance process plants’ safety

    Today’s guest blogger is discussing the growing challenges of emission control, what kind of standard compliance is required and how does a valve supplier answer to these demands.

  • 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.

  • Valves in delayed coking units – why they matter

    Refineries need to improve profitability to stay competitive in today’s market. Delayed coking for heavy and sour oil refineries is potentially one of the most profitable operations available to refiners. Since 1994, almost all residue upgrading in the US has been done with delayed coking. And although coking technology may seem mature, innovations continue to bring improvements.

  • Intelligent solenoid valves: slash time and costs with knowledge

    When a refinery in South America was approaching its scheduled three-year maintenance shutdown, it decided to take advantage of the information provided from its intelligent solenoid valves. Earlier, the refinery had decided to install these valves on every emergency shutdown (ESD) valve to identify degradation by using partial stroke testing (PST) for these critical valves.

  • Valve portfolio built on innovations

    In 1973, Antti Nelimarkka, the creative engineer behind Neles range of valves, came up with an idea that was fine-tuned until production commenced in 1975. For the valves to be more reliable in demanding conditions and applications, Nelimarkka thought of using a metallic seat ring instead of a rubber one—and the game-changer was born.

  • Gaining deeper insight to solve valve cavitation

    Since cavitation is one of the most significant causes of wear, it is important to control the impact of the fluid flow. Using advanced computational fluid dynamics (CFD) to model cavitation helps you reach quicker, more efficient results and deeper insight for your designs, avoiding any premature failure of your control valves.

  • Maximum pipeline performance requires maximum control

    In the US alone, there are approximately 95 000 miles of pipelines. All along the way, control valves should be optimizing throughput. But pipeline operations present a unique set of challenges for valves; they have to operate reliably and efficiently to handle crude oil impurities such as water, ice, dirt and sand 24/7/365. Another important issue is effectively managing through while dealing with noise and cavitation problems. These all can potentially result in costly safety and operational issues.

  • Increased refinery reliability with emergency shut-off valves

    The highest degree of reliability is expected from on-off and safety valves, as unnecessary shutdowns lead to excessively high costs.
