Ethylene manufacturing is a continuous race to be commercially competitive in a volatile global market.
Ethylene manufacturing is a continuous race to be commercially competitive in a volatile global market. Innovation and resourcefulness toward this goal comes in many forms:
Processing low-cost feedstocks, including cheap or “dirty” hydrocarbon streams
Feedstock flexibility—i.e., a nimbly changing feedslate based on market conditions
Modifying cracking severity to maximize selectivity of high-value products
Extending unit, reboiler or plant run lengths
Recycling streams to maximize the recovery of high-value products.
Each of these strategies measurably impacts fouling severity within a given plant; to quantify this impact is a challenge. Underestimating potential fouling events, or
