It is important to optimize energy conservation measures in new projects in process industry. Integration of new plant with existing infrastructure is the key in energy conservation measures. New technologies like Cogeneration and Kalina Technologies are the most suitable technologies to be considered in design phase for energy optimization.
KNPC has recently commissioned a new gas plant LPG Train-4. Various energy conservation ideas are commissioned during start-up as listed below.
Gas Turbine Inlet Air Cooling
Low Temperature Energy Conversion
Commissioning of Waste Heat Boilers to extract heat from Gas Turbine exhaust gas and using the steam as heating medium in column reboilers to achieve enhanced thermal efficiency
Recovery of heat from Spent Hot Regeneration Gas in the Regeneration system
Commissioning of control system to operate air fin-fans based on temperature
Commissioning of Debutaniser side reboilers to extract heat from Compressor discharge gas and effectively saving steam consumption
Cooling Feed gas compressor discharge using Demethaniser bottom fluid
VSD Motor application
Boiler Feed water Preheat
These technical innovations are implemented in LPG Train-4 to achieve energy conservation.
