ALK-SIM™

Alkylation is a key process that creates high-value products from intermediate refining streams. Use ALK-SIM, proven over decades of use within refineries worldwide, to evaluate alkylation of various C4 and C5 olefin isomer feeds under different scenarios of iC4/olefin ratio, reactor temperature and acid strength. For specified feeds, operating conditions, and constraints, the program determines resulting product flows and properties and overall unit operating economics.

Benefits:

• Selectoperatingtargetsby determining the effects of increasing the iC4/olefin ratio by changing recycle rate and the effects of changing reactor temperature
• Discovertheeffectofchanging acid strength
• Evaluatetheeconomiceffectsof recycling more iC4, increasing acid strength, or lowering reactor temperature and the economics of alternate reactor configurations Maintain the refinery LP
• Findoutwhatvectorsareneeded to model the incremental yields for different olefin feeds and operating conditions in the LP
• Allowsrapidregenerationofdata when model or LP structure changes Understand unit behaviour
• Understandtheeffectsofanew feed on alkylate product qualities and yields
• Evaluatetheyields/propertiesfor C3/C4/C5 olefin feeds
• Trainengineersandoperatorsnew to alkylation operations through a series of simulation runs to evaluate cause-and-effect results Monitor unit performance
