    Blog: Components in a Butterfly Valve

    The team managing education services for the Fisher brand of valves and instrumentation has a lot of really good videos on valve basics. You’ll find these on Emerson’s Fisher Valves & Instruments YouTube channel. For example, a recently posted video, What are the Components of a Butterfly Valve? , provides an under 2-minute look at what makes up a butterfly valve and differences in types of valve. ...

    Blog: How to Setup Keystone Actuator Mechanical Limits

    As part of Emerson’s acquisition of the Pentair Valves and Controls business , the Keystone brand of valves and actuators joined the final control area of Emerson Automation Solutions. Over on the Bettis YouTube channel, is a great series of videos in setting up Keystone EPI2 electric actuators . I’ll recap a few points made in the first video, Keystone EPI2 Setup & Commissioning Video 1 Setting Mechanical...

    Blog: Improving Pressure Relief Valve Fugitive Emissions

    In an earlier post, Creating Pressure Relief Valve Fugitive Emissions Testing , we described the advancement of this effect to create standards in this area. I joined Emerson’s Dr. Amr Gado and Calvin Deng as they presented this work in an Offshore Technology Conference (OTC) technical track, Striving Toward Safety Excellence in Offshore and Subsea Environments . Manufacturers and producers are seeking ways...

    Blog: Filling Gaps in Global Safety Standards

    A safety instrumented function (SIF)’s purpose is to reduce the risk of a specific hazard. For example, an upset condition in an oil and gas production separator may cause a series of SIFs within a safety instrumented system (SIS) to shut in the wells feeding the separator. A SIF contains a sensor, logic solver and final control element—often an emergency shutdown valve. As a mechanical component of this safety...

    Blog: Valves for Frequent Cycling, High Pressures and Temperatures

    David Leavitt described an application of high-cycling valves in a dehydration process at the Offshore Technology Conference (OTC) in Houston, Texas. I recapped his presentation last week in a post, Triple Offset Valves and Molecular Sieve Adsorption Applications . He compared rising stem ball valves and triple offset valves (TOVs) used in these applications. David describe a concentric butterfly valve design, a dual...

    Blog: Triple Offset Valves and Molecular Sieve Adsorption Applications

    Adsorption , different from absorption, is the process of the: … adhesion of atoms , ions or molecules from a gas, liquid or dissolved solid to a surface . [1] In process manufacturing operations, adsorption is sometimes used in dehydration or purification processes. In the oil & gas industry, this method is used to dehydrate and remove contaminants from natural gas. At next week’s 2018 Offshore...

    Blog: Simplifying Oil and Gas Production Site Installations and Operations

    Consider the flow path of oil & gas production from the well head. The first stop is typically the production separator where the oil, gas, condensation, water, brine and other fluids and sediment get separated. Traditionally, for multi-well sites, there is a test separator so that each well’s production composition can be assessed. In this arrangement the wells are connect to both a test and production manifold...

    Blog: Wellsite Valve Manifolds Simplified —By Joseph Zawacki

    : Connecting multiple production wells or flowlines to a test separator normally requires multiple valves, each of which has to be opened by hand to connect each well in turn. In addition to valves and shutoff devices, such a system requires consider...

    Blog: Analyzing Vibration in and Around Control Valves—By Shawn Anderson and Adin Mann

    Excessive vibration can cause damage to a control valve, measurement equipment and the piping system. It’s often difficult to find the source of the vibration, which can originate not only with the control valve, but also with upstream and down...

    Blog: Solving Control Valve Vibration Challenges

    The production areas of many process manufacturing facilities can sometimes seem deafening. Some of this noise may be attributed to excessive vibration surround equipment such as control valves, piping and instrumentation. Emerson’s Adin Mann and Shawn Anderson have written a great Flow Control article, Analyzing Vibration in and Around Control Valves to look at the causes and remedies for excessive vibration...
