Home Technologies & Solutions Solutions Complete Product Lines Solution Chlor-alkali


The Chlor-Alkali process is an industrial technology for the electrolysis of sodium chloride (NaCl) or potassium chloride (KCl). This technology is used to produce chlorine (Cl2), sodium hydroxide (NaOH, caustic soda) or potassium hydroxide (KOH, caustic potash) and hydrogen (H2), which are commodity chemicals required by industry. BCMC was founded in 1966, a 100% subsidiary of BLUESTAR under ChemChina. Focusing on providing chlor-alkali complete equipment and electrode energy-saving refurbishment technology, BLUESTAR is a global engineering company which integrates engineering, technology, service and trade together to provide integrated solutions for chlor-alkali plants, upstream & down-stream supporting technologies, as well as EPC general contracting.

BLUESTAR is one of the top four electrolyzer suppliers in the world, and is a Permanent Director of China Chlor-Alkali Association, member of Euro Chlor, Russia Chlor and the Chlorine Institute. BLUESTAR ’s electrolyzer production capacity ranks the first in the world, with an annual production capacity of 3 million tons electrolyzers and 5 million tons electrodes.

As a world-leading electrolysis technology supplier, BLUESTAR / REWINZ is capable of providing our customers with engineering design, consulting and management services of all processes including primary brine, secondary brine, electrolyte circulation, de-chlorination, chlorine and hydrogen treatment, hydrochloric acid synthesis, caustic evaporation and flaking, transformer/rectifier and DCS controlling.

To meet the diversified needs of customers, Bluestar has been doing research & development continuously and have signed long-term strategic cooperation agreements with main downstream chlorine product suppliers who own technical know-how to provide the latest technology and high quality service.

We can provide you with downstream products such as VCM, PVC, PAC, TDI, PO calcium hypochlorite, epoxy chloropropane (ECH), chloride methane, chloronitrobenzene, sodium hypochlorite, etc.
For the above mentioned products, EPS services including basic design, detailed design, core equipment supply and training can also be provided.

We can not only provide cost-effective solutions for chlor-alkali plants, and technology & after-sales services within 48 hours, but also supply the full-life cycle monitoring & management of chlor-alkali plant related to process and technology which will be realized with our targeted professional knowledge, high quality engineering, full-service and high efficient work.

Technology Development-Zero-gap electrolyzer

Our core product is high current density natural circulation bipolar zero-gap electrolyzer, which could be operated  steadily with 6.0 kA/m2 and an expected power consumption of 2000 kWh/t-NaOH 100% basis, representing the best operating parameters worldwide.

Skid-mounted small sized caustic soda plant

BLUESTAR BSM-series Skid-mounted Small Sized Caustic Soda Plant, is the use of our own intellectual property rights of electrolyzer manufacturing technology, process design and operation experience, through the optimization of process design, three-dimensional design simulation, etc. to achieve the following advantages of small caustic soda plant construction:

– Small footprint

– Short construction period

– Low investment cost

The optimized pipeline and equipment are designed modularly according to the process, and the module is divided according to the specifications of 20” and 40” standard containers, which makes full use of the longitudinal space of equipment arrangement and saves the floor space.

The scale of BLUESTAR BSM series skid-mounted caustic soda plant can realize the skid-mounted supply from 20 tons to 30,000 tons of 32% caustic soda per year, BSM series products series are: BSM20BSM500BSM5000BSM10000BSM20000BSM30000, total 6 series.
