GPE’s detail engineering services can be either clubbed with complete process engineering or provided standalone, depending on customer preferences. Licensed software such as HTRI, CAESAR, STADD and PV Elite are used for calculation and analysis. 3D modeling is done using CADWorx or Pro/Engineer.


  • General Arrangement Drawings and 3D model
  • Isometrics
  • Code Calculations
  • Thermal Calculations
  • Fabrication Drawings
  • Structural Analysis & Drawings
  • Hydraulic Calculations
  • Flexibility Analysis
  • Data Sheets
  • Instrumentation Details
  • Electrical Details

Detail Engineering offered for:

  • Gas / Liquid dehydration packages for refinery, fertilizer and petrochemical applications
  • Gas separation and purification plants – Integrated biogas plant, Coke oven gas desulphurization, DME removal from LPG stream, Claus Plant
  • Gas / liquid cleaning – Cyclone/ demister/ vane separation, coalescing and particulate filtration systems
  • Compressed gas systems – Reciprocating compressors and diaphragm compressor packages

GPE also provides project management and procurement support wherein the customer (typically EPIC Companies) purchases the materials directly based on our recommendations. GPE supervises the installation and commissioning of these packages.
