Feed Water Pump, Lean Solution Pump, Semi Lean Solution Pump and Ammonia Feed Pump – Retrofitting existing FCMA starter with Variable Frequency Drives for High Voltage Motors having synch transfer.

Application:Feed Water Pump, Lean Solution Pump, Semi Lean Solution Pump and Ammonia Feed Pump
Project Scope:Retrofitting existing FCMA starter with Variable Frequency Drives for High Voltage Motors having synch transfer.

One of the largest fertilizer producers in Asia which accounts for nearly 15% of the total Urea produced in the country. Having total installed annual production capacity of about 3.4 million MT. These plants use state-of-the-art technology from Denmark, Italy, United States and Japan.

This is a state-of-art manufacturing unit and is among the most efficient plants in the world and uses the latest technologies from KBR and Toyo Engineering Corporation, Japan.

Site Challenges

  • Existing installation was having repetitive failures resulting in huge production loss and safety issues.
  • High Starting current of high-power motors on Gas Turbine.
  • Selection of right method for starting and operating of heady loads.
  • Solution with bump less transfer for smooth operation.
  • Coordination for acceptance of proposed engineered solution with Technology supplier contractor, OEM and End Customer.
  • Replacement of existing motor.
  • Meeting compliances for a sensitive COG plant.
  • Faster delivery for meeting plant shutdown timelines.
  • Requirement of a reliable solution for critical applications.
  • Turnkey retrofit project.

Solution

After a detailed discussion on selection for suitable starting method considering starting current, power factor, capacity available in GT, overload requirements and Space in switch room, it has been decided to go for variable frequency drives with bump less synchronous transfer offering flexibility of speed regulation as well only for smooth start and stop.

We have offered a complete EPC solution having HT VFD with External Transformer, HT Motor, HT Switchboard along with other associated electrical package for meeting the site requirements.

Key features & benefits

  • Fuseless VFD system for long term reliability and availability.
  • Speed regulation as well as soft-starting of application.
  • Smooth starting on GT.
  • A Global design offering full compliance with international standards.
  • Meeting stringent compliances of input harmonics and output distortions.
