LUDY Petroleum Equipment offers a gas sweetening (H2S-removal) solution by molecular sieve technology for natural gas treatment and processing. Gas sweetening by molecular sieve is industry-proven process, which offers effective hydrogen sulfide removal from natural gas stream. Hydrogen sulfide (H2S) is a toxic and corrosive non-hydrocarbon substance, which is present in some gas reservoirs. Hydrogen sulfide is harmful both for personnel and downstream equipment, and shall be removed before gas is utilized, dehydrated or processes. Molecular sieve gas dehydration unit is one of the solutions that LUDY Petroleum Equipment is offering for effective and safe H2S-removal from natural gas stream. LUDY offers in-house design and manufacturing for mol. sieve gas sweetening units along with other gas processing equipment.
Molecular sieve or mol. sieve process is a very mature technology in gas treatment and processing, mol. sieve sweetening units consists of two, three or more columns filled with solid adsorbents, gas filters, and other associated regeneration equipment. Special solid desiccant, zeolite, is placed in columns. Sour gas (H2S-rich) gas comes in contact with zeolite, and special structure of zeolite captures hydrogen sulfide (H2S) in its porous structure. After inlet gas (sour gas) lost H2S, it becomes sweet gas, and sweet gas is discharged to utilization or processing. Sweet gas is used for utility purposes of oil & gas facility, gas turbines, compressor station (booster compressor station), export, LNG. After sweetening, sweet gas may be sent to dehydration, NGL recovery and other processes. Sweet gas may contain very few amount dust and particles of adsorbent, these particles shall be removed by gas filter local on upstream of columns. Filters protect instruments, valves, upstream equipment and piping from short- or long-term damaging. As H2S is trapped in adsorbent bed, it shall be removed by hot gas. Hot gas is a sweet gas, which is heated by special direct fired heaters up to 315°C and discharged to spent bed (H2S-containing adsorbent bed). In smaller gas sweetening packages, industrial electric heater can be used instead of direct-fired heaters. Hot gas or regeneration gas, is the same gas which is product of the mol. sieve gas sweetening unit. The hot gas picks up H2S and hydrocarbons as it flows upward through the bed, and is discharged to a flare system. This process is called bed regeneration. After regeneration, bed shall be cooled before bed accepts sour gas to repeat the cycle of gas sweetening.
