Maintenance & Reliability


Andrew, Bob, Hydrocarbon Processing Staff

Hawk Measurement Systems has announced a new OptioLaser S300 that can be used for the detection of all types of liquids, regardless of their dielectric properties.

Automation Strategies: Top technology trends in automation for 2018

Resnick, C., ARC Advisory Group

The last several years have seen significant advances in, and acceptance of, new automation technologies.

Reliability: Consider stainless steel tubing for mechanical seal connections

Bloch, Heinz P., Hydrocarbon Processing Staff

If, in days past, you have questioned why hard piping was used for mechanical seal flush lines and seal support configurations in process pumps, you are certainly not alone.

Prevent buckling of tanks with external rafters

Tharakan, J., Suncor Energy Inc.

Most cone roof tanks are designed with roof-supporting structures inside the tank.

Keep a floating roof on an even keel

Skogberg, P., Emerson Automation Solutions

Users of large liquid hydrocarbon storage tanks at refineries and terminals must solve a variety of problems and make trade-offs related to vapor emissions and general structural integrity for these massive containers.

Preventing wire wooling journal bearing failure

Brashler, K., Saudi Aramco

This work details the operation of a 21,000-HP, five-stage barrel pump utilized for seawater injection service.

Improve welding technology for heavy-wall pressure vessels in creep-resistant steel

The standard practice recommended for high-pressure vessels with heavy wall thickness requires the implementation of weld joint preparation with a narrow gap technique. This generally calls for a two-beads-per-layer sequence, along with the use of the submerged arc welding (SAW) process.

Reliability: Include pump wear rings in your upgrade efforts

Bloch, Heinz P., Hydrocarbon Processing Staff

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:

Editorial Comment: It’s all in the makeup of things

Nichols, Lee, Hydrocarbon Processing Staff

This issue of Hydrocarbon Processing features a topic that has been addressed in sections of the magazine for several decades, but has never been a focal point of the publication. That topic is materials manufacturing.

Use your data to its full potential to prevent outages

Creef, B., HIMA Americas, Inc.

In a process plant, the safety system is responsible for the protection of personnel, resources and the environment, by taking the plant to a safe state in the event of a fault. However, is the system capable of contributing more to the plant’s uptime and profitability?
