Corrosion
HP Editorial Comment: The silent assassin: Corrosion
This month’s special report focuses on corrosion. Often, uncontrolled corrosion undermines the mechanical integrity of process equipment and infrastructure. It is often identified as the root cau..
Update on lubrication systems
Several case histories illustrate the pros and cons for maintaining rotating equipment under various plant conditions.Example 1In late May 2013, a US oil-mist provider in one of the Great Lakes states..
Control moisture in ‘wetted’ rotating equipment
In turbomachinery, water is one of the most deleterious contaminants. Left unchecked, moisture can severely reduce the service life expectancy of oil-wetted rotating and reciprocating components by as..
Improve quality of lubricating fluids via filtration
Micro-sized dust particles, along with water, can ruin the best lubricating fluids. Contamination of lubricating fluids can occur due to the byproducts of combustion, metal wear, oxidation and more. T..
HP Water Management: Best practices for RO operations
Widespread use of reverse osmosis (RO) technology in industrial applications began in the late 1980s, following the introduction of polyamide materials that had a significantly higher permeate flow an..
Mitigate heat exchanger corrosion with better construction materials
Better materials can provide optimal equipment service life, reduce maintenance, mitigate contamination by corrosion products and minimize heat loss due to fouling.
Mitigate fouling in crude unit overhead—Part 3
CASE STUDYThe basis for this case study is shown in Fig. 18; it is a crude unit with overhead heat integration. This is a one-drum overhead system with heat integration and no water wash. In an attemp..
HP Engineering Case Histories: Case 76: Simple troubleshooting analysis tips are useful
Analyzing failed parts or poor operation requires the proper skills and equipment. Sometimes these investigations are not always very difficult. Often, troubleshooting a failure just requires a logica..
Mitigate fouling in crude unit overhead—Part 2
Up to 50% of the refinery’s entire corrosion expense may occur in the crude unit. The root causes of the fouling and corrosion issues are often linked to the basic unit configuration choices, as ..
HP Reliability: Why users must update design contractors’ understanding
In early 2012, a rotating equipment engineer was involved in a machinery quality assessment (MQA).1 Located halfway around the globe, this engineer’s new job was to oversee the engineering, procu..
