Jiayuguan Dayou Jiamei Calcium Industry Co., Ltd.

Jiayuguan Dayou Jiamei Calcium Industry Co., Ltd. is a lime plant in China with a reported capacity of 138,000 t of lime. It calcines limestone into quicklime in high-temperature kilns. By capacity it ranks #1173 of 1,349 lime plants tracked in China. It emits about 90,868 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 21,181 cars.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-38467854.

Im Kontext: wie sich diese Anlage vergleicht

Bei 138,000 t of lime ist Jiayuguan Dayou Jiamei Calcium Industry Co., Ltd. unter dem Medianwert von lime plant in China (409,811 t of lime). Untersektor: lime. Als lime plant benötigt es intensive Prozesswärme (typischerweise 600–900°C) für seinen Kernbetrieb — Wärme, die durch Dampfkessel, Öfen oder direkte Verbrennung geliefert werden muss, und Verluste durch ungedämmte Behälter und Rohrleitungen stellen verschwendeten Brennstoff dar. Modulare abnehmbare Dämmung kann diese Verluste um 80–96% senken, Oberflächen auf ≤45°C kühlen, mit Amortisationszeiten oft unter 2 Jahren. Kalkwerke kalzinieren Kalkstein in heißen Öfen bei 800–900°C, und der heiße Branntkalk muss in gedämmten Behältern gehandhabt werden, um Reaktion mit Feuchte zu verhindern.
