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.
Case histories of amine plant equipment corrosion problems–Part 2
Past corrosion incidents provide insight into the causes of corrosion and the preventive actions required to protect plant equipment and reduce costly plant downtime.
The design and construction of large crude oil storage tanks with double-deck floating roofs
As crude oil prices decline, consumption of petroleum fuels is increasing.
Reliability: Could a company be its own worst enemy?
In a recent conversation with a “pump veteran,” we explored his 33 yr of experience with pump original equipment manufacturers (OEMs) from 1984–1997 and with a widely known non-OEM (1997–2017).
Optimize operating parameters for C3 splitters to accommodate feed changes
In the oil and gas sector, fractionation is a vital part of every plant.
Safety in design during mechanical engineering
After a process engineer has completed preliminary documents such as process flow diagrams, material and energy balance, piping and instrumentation diagrams, equipment data sheets, process control philosophies, identifications of the hazardous nature of raw materials, chemicals, byproducts and final products, process equipment layout drawings (plans and elevations), unit plot plans, etc., these documents are issued to other disciplines to carry out further engineering.
Process safety incidents involving simultaneous operations
Some process safety incidents occur as the result of simultaneous or sequential occurrences of operations or activities that interfere or clash with each other.
Minimize engineering errors with competency and proper engineering review
Industry has seen numerous engineering errors during the commissioning phase of projects.
