Process Engineering

Coke oven gas treatment

Our focus in coking plant engineering is on the treatment of coke oven gas in by-product plants. Our engineering teams support our customers at all levels of planning, from the feasibility study stage to the realisation of new facilities, as well as the restoration and maintenance of plants in operation. DMT provides professional solutions from a single source:

  • Refurbishment concepts and studies
  • Process optimisation and bottleneck analyses
  • Process engineering
  • Project management
  • Basic and detail engineering
  • Supply of systems or core components
  • Installation and commissioning
  • Training of operating personnel

Process optimisation in by-product plants

Smooth and efficient processes are essential for the cost-effective operation of by-product plants in coking facilities. DMT provides the following process optimisation support to its customers:

  • Bottleneck analysis and subsequent process optimisation
  • Plant inspection and identification of operational problems
  • Concept development for operational improvement measures
  • Inspection and study reports for process optimisation
  • Training of personnel in operational improvement measures

Coke oven gas treatment methods

The most important techniques in this respect are:

  • Gas cooling - cooling of the hot process gas
  • Gas scrubbing - sequential cleaning of process gas (removal of ammonia, sulphide, hydrogen Cyanide, BTX and naphthalene)
  • Tar extraction - separation of tar from the process gas (& from the condensates incurred during gas cooling)
  • Product recovery - Regeneration of the scrubbing agents applied with subsequent generation of products (such as sulphur from Claus plants, sulphuric acid, ammonium sulphate, ammonia, BTX, naphthalene and tar)
  • Wastewater treatment
