About the course

It typically takes several years for young university graduate engineers to master practical methods used in the process industry to solve problems. Gas condensate Layout/Design and Operations Development Practices is an intensive course for young process engineers to bridge the gap between university education and practical process design and troubleshooting in a short time of five days. After participating in the course, participants will know the most important layout/design practices and will be able to perform the necessary calculations to design and troubleshoot process units.

The course will be interactive involving all participants. The ICTD well experienced instructor illustrates the concepts with examples from his practical experience that he weaves into his lectures appropriately.

Course Objectives

At the end of the course, participants will be able to perform the following:

  • Vaporizer and steam drum heat balance
  • Design pressure, temperature and flange class for all equipment in Stripper system
  • Size all pipes and nozzles in Stripper feed circuit and list hydraulic cases
  • Pressures at all points between a high and low pressure separator
  • Size the Stripper feed flow meter, and permanent pressure drop
  • Steam consumption in ejector
  • Flashing liquid flow rate through a hole in a vessel
  • Control valve size in the Stripper feed circuit
  • Size and layout of recycle compressor suction drum
  • Feed drum elevation from pump NPSH
  • Feed pump motor size
  • Compressor head, horsepower and outlet temperature
  • Number of Stripper feed-bottoms exchangers
  • Relief loads for the following cases; Fire case, Blocked liquid outlet, Inlet control valve fails open, Steam reboiler tube failure, Fractionator power failure and how the results can be quickly checked for relative accuracy
