Hwanghae Iron and Steel Complex steel plant

Hwanghae Iron and Steel Complex steel plant is a steel plant in North Korea with a reported capacity of 1,500,000 t of steel. It produces crude steel from iron ore (blast furnace) or scrap (electric arc furnace). It is operated by Government of North Korea. By capacity it ranks #3 of 4 steel plants tracked in North Korea. It emits about 1,291,164 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 300,971 cars. Its CO₂ per unit of capacity is about 59% above the median steel plant.

Nel contesto: come si confronta questo impianto

Con 1,500,000 t of steel, Hwanghae Iron and Steel Complex steel plant è al di sotto di la mediana di steel plant in North Korea (2,000,000 t of steel). Il suo CO₂ per unità di capacità è approssimativamente 28% al di sotto di la mediana di steel plant. Sottosettore: iron-and-steel. Come steel plant, richiede calore di processo intenso (tipicamente 800–1500°C) per le sue operazioni industriali essenziali — calore che deve essere fornito da caldaie, forni o combustione diretta, e le perdite attraverso recipienti e tubazioni non isolati rappresentano carburante sprecato. L'isolamento modulare removibile può ridurre queste perdite dell'80–96%, raffreddando superfici a ≤45°C, con payback spesso inferiore a 2 anni. Gli impianti siderurgici bruciano carbone in altiforni o utilizzano archi elettrici per fondere rottami; in entrambi i casi, il metallo fuso deve essere mantenuto sopra i 1.500°C e trasferito attraverso estesi tubi e recipienti caldi.
