idi INGEGNERIA DEGLI IDROCARBURI is structured in specialist units able to carry out basic engineering, final design, construction and supervision for the construction of industrial installations, in Chemical, Petrochemical and Natural Gas.

Our operational areas include:


The Process Department is available to develop specific activities such as Feasibility Studies, Basic Engineering and to assist Technical Disciplines during the whole Project up to detail Engineering, Construction and Start-up.

In detail the Process Department is committed to perform all of its typical activities such as Studies definition, Heat & Material Balance with simulator, development of process flow diagrams and P&IDs, sizing and specification of Process Main Item, the development of process documents / HSE for the authorities, the definition of Hazardous Areas electrical Classification for the new Installation, HAZOP and SIL studies support, etc.

Fluid transfer study

  • Pipe lines fluid dynamics
  • Compressor and pumping stations
  • Oil and gas network and pipe-lines
  • Heat loss study
