Cokemaking Technology: from bottleneck analysis to commissioning

The purification of coke oven gas and optimum processes in by-product production plants of coking plants: DMT is your competent partner to provide you with professional and efficient support in every project phase and at every planning level. Our engineers have many years of experience in planning, project management and production. They are familiar with the exact procedures in coking plants and have detailed knowledge of the process of gas cleaning.

We support you optimally at all planning levels with our modern tools for process simulation. We work with highly developed process models in order to be able to accurately represent and simulate the thermal-chemical processes in a gas scrubber or gas cleaning plant. The data and programs are validated with empirical data under real process conditions and support us in the design and planning of new gas scrubbers and gas cleaning plants. On this basis, we can also very quickly identify optimization potential in existing plants in operation. Plant extension such as Claus plants can be planned by our experts.

Cokemaking technology by DMT: From conceptual design to production

When it comes to conversions in ongoing operations, you benefit from the operating experience of our specialists: in addition to their work in planning, our teams also have many years of experience in operation. Therefore, we offer all services from conceptual design, planning, and construction to commissioning of plant components or complete by-product plants , also as EPC and EPCM, in "Greenfield" and "Brownfield" projects.

From tar separators to gas scrubbers and Claus plants, we offer the following services:

In process engineering, our focus is on the cleaning of coke oven gas in the by-product plants of coking plants. Our engineering teams support you at all planning levels, from feasibility studies to the realization of gas scrubbers and plants. We also provide consulting services on the refurbishment and repair of plants during operation. Our comprehensive solutions from a single source include

  • Remediation concepts and studies
  • Process optimization and bottleneck analyses
  • Process Engineering
  • Project Management
  • Basic and detail engineering
  • Supply of plants or core components
  • Assembly, commissioning and inspection
  • Training of operating personnel

Coke plants: Process optimization in by-product plants

DMT supports you with the following process optimization measures to allow smooth and efficient processes for the cost-effective operation of by-product plants in coking facilities:

  • 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 operating personnel for process optimization
  • Treatment processes for coke oven gas

The most important processes for the treatment of coke oven gas include:

  • Gas cooling - cooling of 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

These technologies can also be used for the treatment of other process gases, for example natural gas processing, purification in refineries, carbide production or the cleaning of process gases in the chemical and specialty chemicals industries.
