  2. Kraft process - Wikipedia

    en.wikipedia.org/wiki/Kraft_process

    The kraft process (also known as kraft pulping or sulfate process) is a process for conversion of wood into wood pulp, which consists of almost pure cellulose fibres, the main component of paper. The kraft process involves treatment of wood chips with a hot mixture of water, sodium hydroxide (NaOH), and sodium sulfide (Na 2 S), known as white ...

  3. Process flow diagram - Wikipedia

    en.wikipedia.org/wiki/Process_flow_diagram

    A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.

    en.wikipedia.org/wiki/COMOS

    The system is used to design process engineering. Integration into standard process simulators results in the definition of process data at an early planning stage using process flow diagrams and combination with the engineering of processing plants. Another module is used to make this data more precise.

  7. Process simulation - Wikipedia

    en.wikipedia.org/wiki/Process_simulation

    Process simulation software describes processes in flow diagrams where unit operations are positioned and connected by product or educt streams. The software solves the mass and energy balance to find a stable operating point on specified parameters. The goal of a process simulation is to find optimal conditions for a process.
