UOP Adsorbents in Ethylene Production

For decades, ethylene production facilities worldwide have relied upon UOP adsorbents for regenerative dehydration and trace contaminant removal.

Our 3A EPG and EPG 2 products have been specifically developed for use in cracked gas drying, where optimum adsorbent performance is critical. These molecular sieve products are in continual enhancement in the key areas of stability, dynamic capacity, break-up resistance, and low green oil and coke formation. Collectively, these factors translate to longer adsorption cycles and increased adsorbent life. The EPG family of products is available in several pellet sizes, including a TRISIV form, which optimizes system capacity while minimizing pressure drop.

UOP offers a multitude of specialty adsorbent products for the removal of other contaminants such as mercury, ammonia, methanol, COS, H₂S, and CO₂. Because the proper adsorbent selection is dependent upon your particular stream composition, please contact us using our information request form to discuss your specific needs.

You may already know that mercury can corrode accumulate on aluminum heat exchangers and has been known to cause catastrophic equipment failure as a result. UOP's HgSIV adsorbent is the only regenerative adsorbent product that has been used commercially to remove mercury from ethylene and cracked gas streams. Since you can use HgSIV adsorbent to both dehydrate and remove mercury, this solution typically requires no additional capital cost. The HgSIV adsorbent can be loaded into existing adsorption vessels.

UOP’s integrated approach addresses your needs by identifying the best combinations of adsorbents, particle sizes and choice of location in your process. By doing so, we are able to deliver an optimized solution to meet your purification requirements.
