EZER supports and helps our client to seek the best solutions in plant Engineering for energy saving. For this, EZER strives to maximize energy efficiency.
Below content is to introduce the project according to energy saving.
Objectives
The objectives of client (LG Chem) were as follows
  • Quantification and minimization of energy inefficiency in BTX and NCC plant
  • Manipulation of utility network in whole plant for operating cost minimization
  • Optimization of operation mode in BTX and NCC plant
  • Investigating available points for energy saving in the whole plant
Study Approaches
In order to realize client's objectives, EZER performed the following works as below
  • Maximizing energy efficiency through elaborate simulation modeling,
  • HX addition, operating condition optimization
  • Applying pinch study to investigate minimum temperature approach
  • Utilizing recovered heating source for NCC from BTX energy, which led to about 15.4 MMkcal/hr energy saving
  • Obtaining the licenses about technology of energy saving in NCC and BTX plant
