The original project scope included the development of (4) 50 MMSCFD MRU Gas Processing Systems, each with the following balance of plant materials:

• Instrument Air System with Heatless Dryer
• Flare System
• MCC (Motor Control Center)
• Storage Tanks:
  • (3) 400 BBL Condensate Tanks
  • (3) 60,000 Gal NGL Bullets
• (1) BTEX Unit
• (1) VRU Skid
• (1) EG Skid
• (1) Fuel Gas Heater
• (1) Hot Oil Heater
• (2) Overhead Residue Compressors
• (1) Receiver/Economizer
• (5) CAT 3606 Compressors
• (1) 50 MMSCFD MRU
• Sulfa Treat System
• (2) Control Room Workstations with defined operating systems
• Interconnecting Piping
• Civil, Mechanical, and Electrical Construction

Midway through construction, the scope expanded due to the requirement to double gas processing capacity at each of the four sites to 100 MMSCFD.

Additional Work (Outside Original Contract):

• (1) 450 GPM Amine Plant
