Selecting Valves for Food & Beverage Applications: Flow Control - September 2018
Control of fluid flows and temperatures in food & beverage plants presents a number of challenges, most of which can be addressed with correct selection and application of control valves. Blake Coleman, the Global Chemical Industry Manger for Emerson’s Fisher product line, says temperature control is a very important variable in the food and beverage industry. His article, Selecting Valves for Food & Beverage...

What are Valve I/P Transducers?
As we continue to see a generational shift in the manufacturing industries, I like to highlight educational videos developed across the Emerson business groups. Our group managing Fisher Valves & Instruments products has recently posted a 2:51 YouTube video, What are I/P Transducers? This video, developed by the Valves, Actuators & Regulators educational services team, opens by defining the “I” and the “P”. The...

Power Engineering Aug 2018, Cold Start: Improving Turbine Bypass Valve Reliability—By Mary Barker
As often as four times a year during winter months, a power plant in Wisconsin would miss a scheduled start of its combined cycle power plant due to malfunctions of the turbine bypass valves. When there is an issue with the bypass system, the plant can’t start up, and it can’t shut down properly. Mary Barker, Senior Sales Engineer at Emerson and the Global Midstream Oil & Gas/LNG Industry Manager for Emerson, says...

Article info: LNG Industry, Aug 2018, Optimizing Performance
The efficiency and availability of a plant’s compressors have a direct impact on the profitability of a liquified natural gas (LNG) facility. Downtime can affect the plant’s mixed refrigerant loops and lead to reduced LNG production, along with substantial contractual penalties. One cause of unexpected downtime is often poorly performing anti-surge valves. Joe DeMonte, Global Midstream Oil & Gas/LNG Industry...

Article: Control Engineering Europe, Jun 2018, Butterfly Valves Take Control
Subject: Butterfly valves are lighter, smaller and weigh less than other kinds of control valves—making them the best choice for regulating flow in many applications. This article looks at the advantages and limitations of high performance butterfly valves, and then describes developments making them more suitable for flow control. Standard butterfly valves have traditionally been used for automated on/off applications...

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. It opens describing...

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 to...

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 loop...

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...

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 Technology...

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,...

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 considerable piping. A multiport flow selector (MPFS)—with automatically actuated control—is safer, less expensive, lighter weight and more compact than conventional systems. The...

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 downstream piping and equipment. This article discusses modern techniques to help monitor, predict and solve problems caused by vibration. Solving valve vibration problems is difficult...

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. Many...

Valve World Feb 2018, Dangers of Non-OEM Valve Parts, by Karl Lanes
Although an inexpensive, replicated part may look the same as an original part and may fit into the valve being repaired, it does not meet the original valve manufacturer’s design specifications. This article describes the problems with non-OEM parts, and explains why parts from the original valve manufacturer are far superior. Non-OEMs supply valve parts to the process industry at prices up to 30 to 40 percent less...

Eliminating Troublesome Tubing
This article describes how valve actuator instrument tubing can be subject to abuse and damage from vibration and environmental extremes, and shows how Fisher actuators solve these types of problems. Valve actuator instrument tubing is often subject to abuse. It can be damaged by rough handling during shipping or transport. Workers tend to lean ladders against it, stand on it, pick up valves by grabbing onto the tubing...

Planning and Tools for Successful Shutdowns, Turnarounds and Outages
No matter what you call them—shutdowns, turnarounds & outages (STO)—they are a time that manufacturers and producers must race the clock to repair and restore their production equipment to minimize financial losses from lost production. Valves are some of the critical assets that need to be checked and serviced. They touch the process directly and face the wear and tear caused by the fluids flowing through them over...
