Consumption metrics
Thread Content
This post was last edited by sunjl1981 on 2013-1-6 at 23:10. Could someone provide the consumption metrics for raw materials, auxiliary materials, and utility systems in ion membrane electrolysis plants, acetylene production units, as well as VCM and PVC manufacturing facilities? # , , &
Raw material consumption quotas (per ton of PVC)
Serial number | Item name | Specification | Unit | Consumption quota
1 | Calcium carbide (first-grade) | Gas generation capacity: 290 L/kg | Kg | 15–20 (converted to standard value)
2 | HCl ≥99% | % | Kg | 733
3 | Catalyst | HgCl2 (%): 10–12% | Kg | 1.5
4 | Caustic soda | 30% NaOH | Kg | 30 (calculated as if it were 100%)
(Per ton of PVC)
Serial number | Item name | Specification | Unit | Consumption quota
1 | Deionized water | Cl ≤10 ppm, conductivity ≤10 μs/cm, pH 6.5–8.5 | t | 3.8 (380,000 tons per year)
2 | Circulating water | T < 32°C, P ≥0.4 MPa | t | 450 (based on circulation volume)
3 | Fresh water | T ≤25°C | t | 35 (3.5 million tons per year)
4 | Steam | 0.6–0.8 MPa | 1.35 |
Power consumption | KWh | 750
