How a monitoring alarm system with control and shutdown capabilities prevented costly pump damage and environmental hazards and made the job of the pump operator safer and easier.

Data and life cycle management technology helps refineries maintain equipment and reduce the total cost of ownership.

In the oil and gas industry, custody transfer transactions involve transporting physical substance from one operator to another, including transferring raw and refined petroleum between tanks and tankers, tankers and ships and other transactions. An accurate account of the amount of material transferred is of great value to both the company delivering the material and the eventual recipient. This is especially true in bunker fuel oil delivery since a ship's bunker contributes to the ship's operating cost.

Starting can have a significant effect on the life of the winding insulation of an AC motor.

Picture a manufacturing enterprise with plants in multiple locations around the world. Using a single automation platform that handles discrete, process and motion control with common programming, human machine interface (HMI) and standards-based networks, a night shift operator gathers and logs data on product quality from his production line.

Most VFD systems use some form of closed-loop feedback to avoid surging, excessive noise, and in extreme cases, vibration. A reliable encoder signal is one method that minimizes speed variance and helps eliminate these unwanted effects. Here's how it works.

One of the most neglected tools in the vibration analysis toolbox is phase. This neglect is partially due to the extra time and effort often necessary to collect the information. Many analysts are also not properly trained in phase measurement and analysis.

The past may be prologue to the future, but the time between the two seems increasingly short. In the past, labor, capital and raw materials were considered the underpinnings of wealth creation. Today, real-time process knowledge and innovative management strategies have become far more important for creating value, as evident in the headlines above. Accordingly, the time for systemic change is now. . . the opportunity to reinvent industrial manufacturing and the products and services that surround it have never been greater since the beginning of the industrial revolution.

Use of disposable components in product downstream processing and final fill operations is increasing as technology improves for performing these steps in a single-use mode. There is a high demand for systems that support single-use purification, formulation and filling operations.

VFDs replace mechanical devices and PLCs for lead-lag pump control.

A recent marketing survey found that 84.0 percent of satisfied customers would "jump ship" for a better deal if an opportunity arose. With markets becoming increasingly globalized, customer retention has become a critical part of business strategy. Companies need to ask themselves: What reason can I give this customer to stay, even if my competitor offers a cheaper price? The keys lie in keeping customers loyal to brands and products and ensuring a consistently outstanding customer experience.

Questions are answered about monitoring power consumption and noise level parameters for pumps.

Balancing is essential for minimizing vibration, increasing bearing life and minimizing downtime and repair costs. Follow the guidelines from these standards to balance centrifugal pumps properly.

While scheduled downtime is different from unscheduled, both can take away from a company.

This article explores the use of condition monitoring at the UPM-Kymmene's Wisaforest pulp and paper mill in Finland. Production capacity is 800,000 air dried tons per annum (ADt/a) of pulp and 180,000 ADt/a of kraft and sack papers.

While it is valid to state that energy efficiency is defined as the same level of production achieved at an overall lower energy cost, it is equally important for today's machine builders and automation engineers to remember an energy efficient system can actually translate into higher productivity. This is achievable through a comprehensive approach to energy management.

In today's growing industrialized market, the need for reciprocating pumps is increasing daily. As technology drives modernization, the demand placed on the pumping systems is continually rising.

The 4-20mA current loop is used to transmit analog data representing various process variables like level, pressure, temperature or flow. Although conceptually simple, a 4-20mA current loop can be tricky to troubleshoot. Current flows in a single direction through each device in the loop.

Last month we reviewed the pump selection criteria for a typical constant pressure-variable flow (Cp-Vf) application that utilized variable speed (VFD) control. This month we will explore an application where pressure varies in proportion to a change in flow.
