  • HMIs evolve in process control

    New HMI technology is putting a whole new (inter)face on how operators view control systems information, while at the same time driving human error out of systems and improving safe work practices.

  • 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.

  • 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.

  • Getting batch material transfers under control

    Batch material transfer control seems an easy task to carry out, but the reality is that many functions are necessary if the system is to accomplish accurate batch material transfer control. Weighing systems with device-level controls can help.
