  • Heat integration steps can present control problems

    The more energy prices rise, the more heat integration saves. However, heat integration steps can present complex control problems. Slip-ups in putting control systems in place can make operations nearly impossible. That certainly was the case at one unit using heat recovery.

  • Try before you buy

    There is another side to toll processing. It involves the companies that arguably have the best possible know-how and hardware — for the simple reason that they are the equipment manufacturers themselves, offering toll processing services that utilize their own products.

  • Better Design Is No Pipe Dream

    The benefits of using pipeline simulation tools at the piping and instrumentation diagram (P&ID) level, rather than running simulations just on the process flow diagram, can often be overlooked.

  • Draw insights on distillation

    Residue curve mapping is a powerful tool to better understand the design and operation of distillation columns. This article describes how to use residue curve maps to check the feasibility of separation of homogeneous mixtures and for developing the conceptual design of towers.

  • The Synergy of Simulation, Experimentation and Technical Support Activities in a Research Consortium

    For the business of designing process heat exchangers, computational fluid dynamics (CFD) tools are still not practical for everyday use. However, in a research consortium such as HTRI, integrating advanced analysis tools like CFD with industrial-sized experimentation and then applying them to real-world technical problems provides a significant synergistic benefit to the consortium members.

  • Your job is still safe... for now

    With mechanical simulation tools, one engineer can do the work of an entire staff. With chemical processes, however, simulation tools aid the staff — but don’t replace it…yet.
