| Natural Gas Dehydration |
4A |
MS 513 / 514 |
Dehydration to less than 0.1 ppm(v) prior
to liquefaction or Natural Gas liquids extraction |
| Natural Gas Dehydration |
3A |
MS 562 / 564 |
Dehydration to less than 0.1 ppm(v) while
minimizing methanol and / or propane co-adsorption; reduces regeneration heating
requirements and improves yields with less hydrocarbon hold up |
| Natural Gas Dehydration
with min. COS formation |
3A |
MS 562 / 564 MS 562 CS / 564 CS |
Dehydration to less than 0.1 ppm(v); H2S
conversion to COS is less than 0.25% |
| Desulfurization of Natural
Gas / NGL / LPG |
5A |
MS 521 / 522 |
Removal of H2S, COS, and light Mercaptans to pipeline specifications |
| Desulfurization & COS
Min. Natural Gas / NGL / LPG |
5A |
SZ - 5 |
Special COS minimizing 5A sieve for H2S removal; H2S conversion to COS
is less than 4% |
| CO2 Removal &
Dehydration before Liquefaction |
4A |
MS 514 - LNG |
High capacity Type 4A molecular sieve for
removal of CO2 and water to
less than 1 ppm(v) prior to liquefaction. |
| Condensate Drying |
4A |
MS 513 / 514 |
Dehydration to less than 1.0
ppm(w) |
| NGL / LPG Sweetening |
13X |
MS 542HP / 544HP SZ - 9 |
Removal of H2S, COS, Mercaptans
and high MW Sulfur compounds to maintain 1A copper strip LPG / NGL specifications |
