Mitigate vibration issues in shell-and-tube heat exchangers

L&T-Chiyoda Ltd.: Dole, R.  |  Sridhar, S.  |  Vivekanand, S.

Heat exchanger tubes tend to vibrate when influenced by crossflow velocities.

Conduct a design check for depressurization system for cold conditions

L&T-Chiyoda Ltd.: Dole, R.  |  Bhatt, S.  |  Sridhar, S.

Emergency depressurization is a safety provision designed to release gas from a high-pressure system during emergency situations, such as a fire. An overview of cold depressurization is provided, including factors affecting the temperature profiles and critical factors considered while performing the study.

Design a staggered depressurization sequence for flare systems

L&T-Chiyoda Ltd.: Dole, R.  |  Bhatt, S.  |  Sridhar, S.

Emergency depressurization is one of the most important design provisions for safeguarding facilities in case of an emergency. To overcome limitations of flare system capacity during such a scenario, depressurization can be practiced in a sequential manner. Presented here are the criteria and calculation methods for designing sequential depressurization, along with guidelines for the implementation of recommended designs.
