Problems with the operation and configuration of equipment with different loads during the production process of a caustic soda plant with an annual output of 100,000 tons
Thread Content
This post was last posted by sunjl1981 on 2013-1-6 20:26 Edit: Our factory's caustic soda plant production capacity is 100,000 tons of caustic soda per year, 6 Taipei chemical electromechanical tanks, 6 tanks with currents up to 72,000A, 2 chlorine presses, 3 hydrogen presses, 3 +5 degree chilled water units, and 2 -35 degree brine units (for PVC unit cooling capacity). How to configure the opening of equipment under different loads to minimize production costs without affecting production? For example: At 50% load, how many hydrogen compressors should be operated? One chlorine press or two at 70% load? What about chilled water units and chilled brine units? How to calculate? Because the capacities of chlorine presses and hydrogen presses are the standard cubic processing capacity per hour, and the chlorine and hydrogen sent by electrolysis are chlorine and hydrogen at different pressures. Could any kind-hearted brothers and sisters please help me how to calculate them? How to configure the start and stop of equipment under different loads? Thank you#, , &
Why is the situation described by the poster so similar to ours? Now I also need information from Sichuan friends who have experience in this field.
Example C-551A/B Hydrogen Compressor Capability Processing Gas: 3720~4100Nm3/h suction pressure: 0MPa(G) exhaust pressure: 0.3MPa(G) Suction temperature: 15℃ exhaust temperature: 40 ℃ with built-in cooler and gas-liquid separator with motor: N=315KW n=2900rpm N=500rpm Explosion level: eⅡT3
The poster should introduce the workload of your equipment. Thank you! :handshake
Relevant data: The 100% load of the caustic soda plant is an annual output of 100,000 tons of caustic soda (100%), six cells (each with 124 cells) with a total current of 72,000A, and the production capacity of the main equipment: Chlorine press 2328Nm3/h, hydrogen press (outlet pressure 0.1Mpa) 48m3/h, circulating water pump 4645.5m3/h ； Air compressor unit 58.2 m3/min (exhaust pressure 0.85Mpa), +5℃ water unit 1265 m3/h, cooling capacity 4425KW ； -35℃ brine unit 292.1 m3/h﹑Refrigerating capacity 840KW ； When the caustic soda plant is 100% loaded: The circulating water consumption is about 7000 m3/h, the PVC device circulating water consumption is about 1500 m3/h, the instrument air supply is about 800N m3/h, the PVC powder transportation is 1000 N m3/h, the device air is 300 N m3/h, and the nitrogen supply is 1000 N m3/h. ； Schedule: Caustic soda plant load? %, what is the load of PVC device? %, equipment start and stop conditions: Serial number Equipment name Operating status Number of units Remarks 1 Chlorine compressor operation 2 Hydrogen compressor operation 3 Air compressor operation 4 Circulating water pump operation 5 +5℃ unit operation 6 -35℃ unit operation
Could you please provide me with scoring information in this regard? Thank you!
