Sumitomo Chemical 
Chemical Plant
In recent years, petrochemical and basic chemical plants have diversified into higher value-added, larger scale, and overseas locationss. The chemical plants are also required to harmonize with environmental conservation.
SCEC has always responded to the demands of the times, and has successfully delivered a large number of plants, from small-scale projects to national-scale projects. Our projects are not only in Japan but also in Southeast Asia and the Middle East.
SCEC will play a role in business development by flexible and accurate supports to fulfill customer needs with its wealth of experience, technology, and project management accumulated over the past half century.
In Singapore, since 1984, SCES has developed its engineering capabilities by performing plant construction, enhancement and modification, and routine maintenance services, mainly at PCS and TPC. Today, SCES (Singapore Subsidiary) has earned a strong reputation and trust as a locally based organization in Singapore.

Electronics Industry
SCEC started research and development of automatic chemical supply equipment in the late 1970s, when semiconductor manufacturing began to gain momentum, and successfully delivered its first equipment in 1981.
Since then, we have provided many safe and stable systems, mainly this system, contributing to stable operations and labor savings for our customers. Today, we are recognized as global leading supplier of the systems not only in Japan but also in seven countries around the world.
The chemical supply system must be safe, of course, but it is also important to provide a stable supply of chemicals at all times to plants that are expected to operate continuously 24 hours a day, 365 days a year.
SCEC is specialized in chemical supply systems, in which we have gained a great deal of experience in over 1,700 cases and many years of after-sales service.
We accumulated the experience as know-how and constantly fed back to system development and after-sales service to provide highly reliable systems tailored to the characteristics of chemical solutions.
We will continue to respond to increasingly diverse needs and strive to improve customer satisfaction by constructing better systems.

Environment
The origin of our environmental technology can be traced back to sulfuric acid and fertilizer manufacturing technology that removed sulfur dioxide from copper smelting flue gas and recovered it as a resource about 100 years ago. We have accumulated experience in plant engineering rigs for the removal of sulfur oxides, nitrogen oxides, and other harmful (polluting) substances that pollute the environment. Today, industrial facilities are required not only to remove hazardous substances but also to reduce emissions of carbon dioxide and other greenhouse gases, and we are committed to environmental considerations in all activities from planning, engineering, and construction.
Sulfuric Acid Production Plants
SCEC's sulfuric acid plants originated from Japan's first sulfuric acid production facility for the purpose of treating exhaust gas from copper ore roasting. Since then, we have built up a track record of more than 30 plants over the past 50 years, with continuous innovation to the latest technology. Based on this wealth of experience, we provide high quality sulfuric acid production plants from various feedstocks. In addition, we have built up enough experience in the construction of integrated processes in combination with the desulfurization process.
Main features of sulfuric acid plants
・The system can be used for plants of various sizes.
We have experience in the plant capacity from 15 t/d to 2,300 t/d and can accommodate various sizes.
・We can handle a wide variety of raw materials.
The raw materials include single sulfur, copper and zinc refining gas, sulfur-containing compound waste liquid, waste sulfuric acid, and dry type desulfurization gas.
・We always provide the best technology.
Based on our own process technology, we can offer a variety of proposals tailored to customer needs.
