Pumps
Reliability: Consider today’s canned motor pumps
We often make the mistake of letting our equipment selection decisions be governed by old data, anecdotes and traditions.
Reliability: Preserve what worked well in 1980
The second CCC implementation strategy involved so-called “shirt sleeve seminars.”
Show Preview: IRPC Europe returns to Italy this June
Gulf Energy Information and Hydrocarbon Processing are pleased to provide a preview of IRPC Europe 2018, which will be held June 5–7 in Milan.
High-energy pump balance line flow monitoring using ultrasonic flow measurements
The objective of this article is to demonstrate the value of utilizing portable or permanently mounted ultrasonic flow measurement technology to measure and monitor high-energy pump hydraulic balance line flow.
Preventing wire wooling journal bearing failure
This work details the operation of a 21,000-HP, five-stage barrel pump utilized for seawater injection service.
Upgrading the bottom of the barrel
In the past few decades, new technologies, including both carbon rejection methods and catalytic conversion methods, have emerged.
How the “LLF” condition monitoring technique can improve manufactured product profitability
Technological advances have allowed predictive maintenance (i.e., condition-based maintenance) to overtake preventive maintenance in plant operations. “Look, listen and feel (LLF)” is a condition monitoring technique that improves the reliability of equipment and machinery in manifolds.
Reliability: Include pump wear rings in your upgrade efforts
Most centrifugal pump designs include replaceable rotating wear rings on the impeller (impeller wear rings) and stationary wear rings inside the casing (case wear rings). Although pump wear rings are simple components, they can have profound impacts on pump reliability, efficiency and safety. These wear rings serve three purposes:
Consider pitot tube pumps for low-flow, high-head applications
Low-flow, high-head pumping requirements in refining and petrochemical plants make up less than 2% of the total pump population. This minor percentage is creating significant reliability concerns, which result in low mean-time between failures (MTBF), as well as high maintenance costs.
Advancing export terminal technology: An optimized process for the refrigeration of cryogenic hydrocarbons
Ethane production in North America (NA) has expanded dramatically with the onset of shale production and associated hydraulic fracturing. Ethane concentrations in fractured shale gas are typically 10% or higher vs. a traditional range of 4%–7% in associated gas.
