ProjectAMAK
Solution :
Gathering, compressing, dehydrating & sweetening of the sour associated gases
in seven productionflaredwhich are being units and transfer of the sweet gas to NGL plants (NGL700,800) and the acid gas to the petrochemical complex (RAZI).
ProjectAMAK
Environmental Aspects:
• Stop flaring and wasting 241 MMSCFD of associated gases which contain 18,400 ppm of Hydrogen Sulfide
• Stop emission of 18,000 ton/day as polluting material
• Stop wasting of 640,000 m3 /hr of the atmospheric oxygen
