Deep dive into process optimization techniques, simulation tools, constraint analysis, and economic optimization methods.
It optimizes gas processing facilities by providing economic analysis and debottlenecking recommendations to improve plant efficiency.
The calculator provides economic analysis and identifies debottlenecking opportunities for NGL recovery process optimization.
It is designed for gas processing facilities including NGL recovery plants, evaluating overall plant efficiency and economics.
The calculator compares turboexpander (85-98% C2 recovery), JT valve (20-50% C2, low CAPEX), refrigeration (40-80% C2), and enhanced processes (90-99% C2, maximum recovery). Each has different capital and operating cost profiles.
The calculator performs breakeven analysis comparing ethane recovery revenue against gas shrinkage cost. When ethane prices are low, rejecting ethane into the residue gas stream and recovering only propane and heavier components maximizes profitability.
The calculator uses Mont Belvieu purity product prices as the reference. Typical ranges are ethane at $0.15-0.50/gal and propane at $0.70-1.20/gal. The frac spread between NGL value and gas shrinkage drives the optimal recovery level.
