Equipment critical analysis: The need for an effective maintenance program

Toyo Engineering Canada Ltd.: Zardynezhad, S.

Oil refineries and large petrochemical plants contain thousands of pieces of process and utilities equipment that are subject to wear, erosion, deterioration, aging, etc., resulting in increasing breakdowns and outages. Imagine being a maintenance engineer and receiving 50 work orders during an overhaul with a limited budget, time, labor, spare parts, tools, machines, etc. How does that engineer prioritize the work?

Perform field oil flushing for successful centrifugal gas compressor startup

Toyo Engineering Canada Ltd.: Zardynezhad, S.

Many factors are necessary for a successful compressor startup. One of the key actions is conducting high-quality field oil flushing during the precommissioning stage, or after a major overhaul.

Achieve successful compressor startup by addressing dry-gas seal failure

Toyo Engineering Canada Ltd.: Zardynezhad, S.

A common root cause for compressor failure during first startup is a failure of the dry-gas seal (DGS) system. To avoid failures of gas compressors, the project team and end users must understand the importance and significance of the DGS very early in the basic design phase.
