Petroleum Refining

Petroleum Refiners use GPEC molecular sieve systems for a wide range of drying and purification applications including:

• Alkylation feed, where GPEC systems help reduce acid consumption, regenerator use, and corrosion, yielding an overall improvement in alkylate quality; 

• Refinery hydrogen, for preventing corrosion in down stream equipment by purifying the hydrogen feed to the catalytic reformers;
• Refinery gas, for preventing line freeze-ups during cryogenic processing of refinery gas;
• Refined products, where GPEC molecular sieve system are used in the drying and desulfurization of the LPG, and in the drying of naphtha and diesel oil;
• Isomerization, for assisting in the drying and purification of feed and recycle hydrogen;
• Remove residual oxygenates such as water, methanol, MTBE, DME, from MTBE process C4 raffinate streams before delivery to oxygenate-sensitive operation such as alkylation and 1-butene recovery. Product specifications of less than 1 ppmw oxygenates are achieved.
