CPU II Mole sieve changed

CPU II gas plant (CB&I) was commissioning in May 2012, this is the first change for Molecular sieve (M.S) due to decreasing the plant efficiency after using the Mole Sieve long time since 2012.
Location: CPU-II gas plant / CB & I
Duration: Oct 21, 2018   TO  Nov11, 2018
The gas plant has 3 vessels (dehydrators) Molecular sieve; each of three dehydrators contains about 76100 pounds of mole Sieve, each dehydrator contains (68 Drums ceramic balls and 235 drums Mole sieve)
The function of Mole Sieve is remove the water from the inlet gas, the system is designed to dehydrate 420MMSCFD @ 930 PSIG and saturated with water @ 105F
CB&I Normal feed gas =420 MMSCFD and produced as follows:
10420 LPG,
1870 C5+ and 390MMSCFD
