Innovations in process engineering and simulation: insights from Srinivas Maheshwaram

Q1.Can you share some key highlights from your extensive experience in Process Engineering and Simulation, and how it has evolved throughout your career?

  • Process Design: Process engineers are in charge of creating new processes as well as enhancing current ones. Defining the objectives, selecting appropriate equipment and sizing, determining material flow, and developing process flow diagrams (PFDs), piping and instrumentation diagrams (P&IDs), and Heat & Material balance using process simulation software are all part of this process.
  • Safety: It is critical to ensure the safety of employees, the environment, and the process itself. Through safety analyses such as Hazard and Operability Studies (HAZOP) and Process Hazard Analysis (PHA), process engineers must identify and reduce potential hazards and risks.
  • Interdisciplinary Collaboration: To develop and optimize complicated processes, process engineers frequently collaborate with experts from diverse domains such as mechanical engineering, Instrumentation engineering, electrical engineering, Piping and materials science.
  • Process Modelling and Simulation software (Aspen hysys, Aspen Plus, Chemcad, ASPEN EDR and Unisim): Process engineers build virtual representations of processes using modelling and simulation tools. This allows for the analysis, optimization, and prediction of process behavior of the equipment. Simulation software can assist engineers in determining the proper size and capacity of equipment such as reactors, heat exchangers, distillation columns, and pumps. Engineers can simulate the performance of many equipment alternatives and choose the one that best fulfills the project’s needs by entering process parameters and limits.

Team Management: They oversee a team of engineers, designers, and other professionals involved in the FEED project. This includes assigning tasks, monitoring progress, and ensuring that team members have the necessary resources and support to perform their roles effectively.

Q3. You’ve had experience working in various locations, from India to the United Arab Emirates. How has this international exposure influenced your approach to Process Engineering and Simulation in different contexts?

  • Cultural Sensitivity: Working in multiple worldwide locations exposes process engineers to varied cultures, work styles, and communication conventions. This experience can help them alter their communication and management techniques to be more culturally aware.
  • Technological Adaptability: Travelling to different nations may need you to deal with different technologies and equipment. Process engineers with global expertise may be more adaptive and receptive to implementing new technology and best practices from various locations into their projects.
  • Global Best Practices: Working overseas exposes process engineers to a wide range of industry best practices. They can learn from numerous ways and apply what they’ve learned to improve processes and solve problems in a variety of scenarios.
  • Global Networking: Building a global network of professional contacts can help with collaboration, knowledge exchange, and career advancement.

International experience can broaden a process engineer’s perspective, making them more adaptive, culturally aware, and capable of dealing with problems in a variety of settings. It can also improve their ability to harness global best practises and effectively work with stakeholders from all around the world.
