PT. ASAHIMAS CHEMICAL

ASC’s integrated Chlor Alkali-Vinyl Chloride plants in Cilegon, Banten, Indonesia produce basic chemicals for many of downstream industries.

In 1986, ASC was established as a multinational company with its headquarters in Jakarta. In 1989, started operation as its state-of-the-art production complex in Banten province. Over the years, the complex has expanded several times, substantially increasing production capacity. Total investment now stands at USD 545 million. Today, ASC operates the largest chlor alkali-vinyl chloride plant in Southeast Asia. By focusing on chemical and industrial markets, ASC has the capacity to produce Caustic Soda (NaOH), Ethylene Dichloride (EDC), Vinyl Chloride Monomer (VCM), Polyvinyl Chloride (PVC), Hydrochloric Acid (HCI) and Sodium Hypochlorite (NaCIO).

ASC’s shareholders are AGC (Asahi Glass Company, Japan), PT Rodamas (Indonesia), Ableman Finance (British, Virgin Islands), and Mitsubishi Corporation of Japan.

ASC has three plants built on 91 hectares in Cilegon, Banten in Indonesia. Operated by distributed control system, these plants are not only highly efficient but also with high quality standards.
Commited to minimize the operation cost as well as carbon emissions. Constantly develops and seek for improvements by using the latest technology.

In the first process, which consists of three trains, Caustic Soda is produced. The derivative products include: Chlorine Gas, Hydrogen, Hydrochloric Acid solution and Sodium Hypochlorite solution.

The second process produces Vinyl Chloride Monomer as a raw material for production of PVC. This plant consists of two trains. Chlorine Gas, which is generated in the Chlor Alkali plant, reacts with Ethylene to produce Ethylene Dichloride; this is then cracked into VCM.

The third process, made up of three trains, produces Polyvinyl Chloride, and it is at this stage that VCM is polymerized into PVC.
