Mhlume Expansion

Summary

  • First phase of a four phase expansion project of Mhlume Factory to increase crushing rate from 390tch to 440tch with the aim of enabling on-the-run cleaning of evaporators to improve overall time efficiency
  • Dismantling of workshop and construction of a new evaporation station and modification of the existing evaporation station within the existing factory building
  • Emineo acting as EPCM for the project, managing sub-contractors from Swaziland, South Africa, India, and Mauritius
  • Country: Swaziland
  • Contract period: 2017-2018

Engineering

  • Modification of three existing evaporator lines into a single quintuple effect line with redundant vessel that will enable on-the-run cleaning without decreasing crushing capacity
  • Installation of four 3000m2 Kestner evaporators with accept/reject condensate system
  • Installation of a new direct contact heater and new condensers
  • Specification of all process, mechanical, electrical and instruments
  • 3D Modelling of zones affected by the project using 3D AutoCAD to build a Navisworks model used by all contractors on site
  • Generation of general layout drawings, piping isometric drawings, structural guide drawings, civil guide drawings, electrical & instrumentation layout drawings

Procurement

  • Evaporators and condensate receivers manufactured in India
  • Direct contact heater & condenser manufactured in South Africa
  • Storage tanks manufactured in Swaziland
  • Steel structure manufactured in Swaziland
  • Large bore piping manufactured in China
  • Large bore valves manufactured in France
