Ịgha gasị nke ụwa maka ịmepụta syngas: Nkọwa ihe ọhụrụ:

Ngwaọrụ anaghị ike na-enwekarị 3.5 MPa, na-enwekarị nke ọma ka ọ bụrụ ≤0.1 ppm, wee tụọ ya na mmanya mmanya n'otu nisakọ nke iri abụọ na ise. O bugha ngalaba mmanya mmanya, ebe methane enweghị ike na 800–900°C na 2–3 MPa n'okpuru catalyst nickel, na-eme mgbanwe methane ≥95%. Enwere ike inweta syngas nke omenala H₂/CO dị ka 3.0, na inweta ike ≤27 GJ maka otu ton ammonia.

Syngas ruo hydrogen: Nkọwa ihe ọhụrụ:

Syngas na-agba ọsọ ọsọ na-emetụta CO gaa na H₂ na CO₂, mgbe ahụ na-agba n'usoro nchekwa obi (PSA) iji nweta hydrogen nke omenala ≥99.99% ma ọ bụrụ na mmegbu ≥85%. A na-atụgharị gas desorption gaa na ngalaba reforming dị ka ebe, ma a na-enye hydrogen na mpaghara ahịa gaa na ngalaba hydrogen ma ọ bụ na ngalaba nnukwu.

Nkọwapụta usoro nke synthesis gas na synthetic amonia:

Akwụkwọ syngas pụrịfaraịd na-enweta nitrogen n'ime mmiri nke dị na H₂/N₂ nwere ike 3.0, enweta obere obere 14–16 MPa, ma si na-ejide ya na radial ammonia synthesis tower. Ammonia a na-enwe ya n'okpuru iron-based catalyst nwere oyi 400–450°C, nke nwere ike ikwusi aka maka mmalite ≥18%. A kwụsịrị ammonia liquid siteere ya.

Nkọwapụta usoro nke Syngas na Methanol:

Syngas enwetaghị obere obere 5–8 MPa ma si na-enwe ya crude methanol n'okpuru copper-based catalyst nwere oyi 220–260°C. Nchịkọta ụtụ nke na-eme ya bụ 2.5 MPa steam dị ka njem mbụ. A kwụsịrị AA-grade refined methanol siteere ya site na distillation nke atọ akwụkwọ, nke nwere ike ịmụ iwu ụtụ ≤28 GJ per ton of methanol ma si nwere ike ịmụ ụtụ ≥3 afọ.

Oge mmepụta, nrụnye, na ntinye aka:

Iji ihe mberede modular, ihe omume dị ka reforming furnaces na synthesis towers dị n'ime factory ma si na-ejide ha na mpaghara ahụ. Oge kachasị elu maka ngwaọrụ ahụ site na inweta contract ruo mgbe ọ na-acha ụtọ bụ 10–12 months.
