Process Engineering

We have extensive experience with chemical and petro-chemical processes. We have also performed projects for the oil refining and power industries.

We specialize in projects requiring process simulations and engineering computations for process apparatus, process lines, and installations. Using modern computer-aided techniques, e.g. ChemCAD and CCTherm software, we can perform technical analyses even in very extensive and complicated process installations. Using the software, we are capable of simulating multiple variants for each chemical or petrochemical installation. We validate the simulation results with experimental data.

The simulations allow us to:

  • Produce conceptual and process designs for new process units
  • Perform apparatus selection, in particular distillation and absorption columns and heat exchangers
  • Perform mass and energy balance for process lines

For existing installations, we offer the following services:

  • Throughput calculations for each process device
  • Identification of process intensification opportunities by finding and resolving process bottlenecks
  • Process optimization for energy consumption and output product quality
  • Analyzing opportunities for using existing installations for new production profiles

Our simulations and calculations based on installation models constructed in ChemCAD have been verified in practice for many process installations.

We design processes for (among others):

  • liquid and gas transport
  • heat exchange
  • distillation, absorption and desorption
  • extraction
  • chemical reactions (especially oxidation and hydrogenation)

Project documentation is prepared using CAD software, according to our high internal standards, or according to the client’s specification.

Currently our main tools are:

Industrial Process Safety

One of our specializations are industrial safety projects. We have the theoretical knowledge and practical experience to:

  • Create technical documentation for high and elevated risk sites, in compliance with the Polish law (Prawo Ochrony Środowiska act from 27 april 2001, Dz.U. z 2016 r. poz. 672, with later changes)
  • Conduct safety analyses for industrial sites, in particular using the Hazard and Operability Study method
  • Identify the required Safety Integrity Level for safety control equipment

Technical documentation for high and elevated risk sites

For high and elevated risk sites, we prepare complete technical documentation for serious industrial accidents, in compliance with the Polish law (Prawo Ochrony Środowiska act from 27 april 2001, Dz.U. z 2016 r. poz. 672, with later changes, and related acts). We prepare:

  • Safety reports
  • Accident prevention plans
  • Internal emergency response plans

In particular, we specialize in preparing safety reports in compliance with the Polish Minter’s for the Industry, Employment and Human Services regulation from 28 May 2003, regarding the requirements for high risk industrial sites (Dz. U. Nr 104, poz. 970, with later changes). The high quality of reports we produce has been recognized e.g. by the Fire Department Regional Headquarters in Opole.

Risk analysis using the Hazard and Operability Study (HAZOP) method

Over the years, Atechem’s engineers have acquired broad experience related to conducting risk analysis studies using the HAZOP method. We organize and conduct HAZOP meetings with the participation of the investor, the designers, and users of the given industrial installation.

A HAZOP study is a popular tool used to identify possible accidents, potential dangers and their consequences.

For large projects involving national and international companies, HAZOP is the accepted standard operating procedure for verifying the P&ID schemes with respect to the safety of the proposed solutions.

Identifying the required Safety Integration Level

Atechem’s services include indentification of the required Safety Integration Level for the safety control systems, according to the IEC 61511 norm, using both the risk graph and the LOPA methods.

Laser scanning

We carry out inventories of buildings and piping using laser scanning.

This method allows us to:

  • optimize and simplify inventory work,
  • significantly shorten the duration of inventory work,
  • obtain high quality measurements (in comparison with classical methods),

Inventory, that is carried out in such a way allows to obtain cloud of data points. Based on that it is possible to create a 3-D model, which can be used in further processing and developing proper design documentation (along with the material specification, state of stress and strain during work etc.)

This method is applicable for inventory of:

  • construction objects (steel constructions, flyovers, buildings etc.),
  • pipelines,
  • storage and process tanks,

If you have a design documentation in the form of a three-dimensional model, this method can be used to verify the compliance of the constructed object with the project.
