Asia Chemical Engineering Co., Ltd. is one of the most reliable manufacturers and suppliers of caustic soda plant for chemical industry in China. Please rest assured to wholesale cost-efficient caustic soda plant for chemical industry from our factory. Good service and reasonable price are available.
Chloralkali process is one of the most important chemical manufacturing processes.
Caustic soda (NaOH) is widely used in:
Organic chemical manufacturing
Petrochemical processing
Industrial cleaning chemicals
Detergent production
Water treatment chemicals
Resin and polymer production
Pulp & paper chemicals
Textile chemicals
Alumina refining
For many chemical factories, producing sodium hydroxide on-site helps:

FAQ：
1. What is the investment cost of a caustic soda plant?
The investment cost of a Caustic Soda Plant for Chemical Industry depends on several factors, including production capacity, membrane cell technology, automation level, and local installation conditions.
Generally, key cost drivers include:
Plant capacity (TPD or T/Y)
Chlor-alkali technology type
Power consumption system
Brine purification system complexity
Chlorine and hydrogen recovery integration
EPC scope (equipment only or full turnkey)
For a precise quotation, a customized engineering design is required based on your project requirements.
2. How much electricity does a chlor-alkali plant consume?
Electricity consumption is one of the most important operating costs in the chlor-alkali process.
Modern membrane-based caustic soda plants typically:
use significantly lower power than diaphragm systems
optimize energy efficiency through advanced rectifier systems
reduce overall cost per ton of NaOH output
Energy usage depends on:
cell efficiency
brine purity
operating load stability
system design optimization
3. What raw materials are required for caustic soda production?
The main raw material is industrial salt (NaCl), which is processed into purified brine before electrolysis.
Required inputs include:
Industrial salt
Demineralized water
Electricity
During production, the system also generates:
Chlorine gas
Hydrogen gas
These by-products can be recovered and reused in chemical production processes.
