LPG Sweetening + Deep Purification Retrofit for Refineries

Multiple small and medium private refineries in China faced LPG mercaptan exceedance and insufficient deep desulfurization precision, causing frequent poisoning and loss of downstream alkylation unit catalysts.

We supplied a complete consumables system — high-purity sweetening catalyst + T306 high-precision zinc oxide desulfurizer + dechlorination and dearsenification guard catalysts — for full-dimension deep feedstock purification.

LPG mercaptan removal ≥99% with outlet total sulfur stably below 0.05ppm, effectively protecting downstream core equipment and high-value catalysts and sharply reducing shutdowns — now the standard high-repurchase solution for local small and medium refineries.
