EZER can help the clients to produce the products in regulatory requirements for flare system.

Below content is to introduce the project according to flare system.
 
Environment around Safety
  • More severe basis for safety analysis and demand for rigorous calculation because of awareness of problem caused by short-cut calculation in the past
  • Difficulty from flare modification when capacity of revamping plant was upgraded
  • Demand from government and client about acquiring flare load calculation basis
  • Need for safety load re-calculation emerged by feed composition change, small modification, utility change by energy saving
Study Approaches
  • Steady state simulation for rigorous calculation (conventional method) in terms of normal and abnormal conditions
  • Reanalyze the whole plant data (PFD, Equipment & Instrument DS, P&ID, Utility System and others)
  • Supply and instruct specifically suitable basis on flare analysis to client
  • Program customization for DYNAMIC SIMULATION based on the consideration of limitation in simulators
  • SIS application based on the consideration of safety and economic feasibility
Solutions
In order to solve the problems and to meet the client's needs, EZER performed the following works as below
  • Setting scale-up parameters through operation data gathering of the pliot plant
  • Scaling up and scheduling multiple batch process into stable continuous process
  • Selecting Material resistant to Sulfuric acid
  • Changing optimum operating condition through the simulation model for energy saving
  • Rearrangement of HX with pinch study and simulation modeling for energy saving
