Rotating Equipment


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.

How the “LLF” condition monitoring technique can improve manufactured product profitability

Das, S., Bahrain Petroleum Co. (Bapco)

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

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:

Reliability: Dry gas sealing technology replaces segmented carbon rings in small steam turbines

Bloch, Heinz P., Hydrocarbon Processing Staff

Since the late 1800s, small steam turbines have incorporated bushing-type, single-piece and/or segmented carbon gland components to reduce and prevent steam leakage along the shaft.

Safety: Process safety and risk management— An industry view

Jones, S., Petrotechnics

In 2017, Petrotechnics released its process safety and risk management (PSM) survey.

Reliability: Could a company be its own worst enemy?

Bloch, Heinz P., Hydrocarbon Processing Staff

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).

Balanced oil sealing solution reduces lube oil leakage at compressor drive train

Langela, M., STASSKOL GmbH

Reciprocating compressors use a piston rod connected to a drive train at the crosshead section.

Optimize operating parameters for C3 splitters to accommodate feed changes

Sami, M., Contributing Writer

In the oil and gas sector, fractionation is a vital part of every plant.

Troubleshooting the repetitive failure and shaft seizure of a hot oil circulation pump

The Shaybah NGL recovery plant has a single-stage, double-suction between bearings, radial-split design for hot oil circulation.

Reliability: Choices—Treat the symptom or define and eliminate the cause?

Bloch, Heinz P., Hydrocarbon Processing Staff

In an urgent communication, a paper plant customer reported that the mechanical seals in one of its ANSI pumps were moving axially whenever an unexpected process problem caused the normally liquid pumpage to turn into a thick, odorous gel.
