In the realm of asset management, ensuring the optimal operation and longevity of key machinery is paramount. One such instance necessitating intricate scrutiny was the damage to the compressor of the MgO#1 pre-evaporator in South Africa. This article delves into the investigation, its findings, and the consequential recommendations put forth by Anssum.

Project Overview

  • Focus Area: Asset Management
  • Country: South Africa
  • Description: Compressor Damage Investigation
  • Status: Completed
  • Timeline: April 20, 2022 – May 5, 2022

The Investigation

Anssum initiated a thorough examination to decipher the underlying causes contributing to the damage of the compressor. The investigative process highlighted a key issue: the malfunctioning of the demister was a primary factor aggravating the compressor’s damage.

Anssum's Recommendations

The study culminated in the following salient recommendations:

  • Demister Spray Alignment: The demister sprays were identified to be prone to misalignment. This misalignment resulted in water being sprayed directly into the compressor’s feed, leading to operational discrepancies.
  • Operational Procedures: Concerns were raised about the operational procedures associated with the compressor. Notably, the practice of washing the compressor with water during its operation, primarily due to the accumulation of black liquor on its blades. This issue was further linked to the underperformance of the demisters in the MVR (Mechanical Vapor Recompression).
  • Design Specifications: It was observed that the compressor was frequently operating outside its design specifications. This deviation not only exacerbated the damage but also ushered in production and asset management challenges. It was emphasised that such concerns went beyond the current scope of supply and warranted immediate attention.

Concluding Remarks

The compressor damage investigation underscores the importance of meticulous asset management and the need for proactive interventions. By identifying potential pitfalls and offering actionable recommendations, Anssum reaffirms its commitment to ensuring operational excellence and safeguarding assets.

Anssum’s dedication to thorough investigations and informed recommendations solidifies its position as a trusted partner in asset management endeavors.
