SK energy Co., Ltd.

SK energy Co., Ltd. is the largest general petroleum and petrochemical company in South Korea. It has recently integrated the monitoring and control processes for the production of petrochemical products with the aim of improving operational efficiency and optimizing the allocation of human resources at the production facilities. As a result, the monitoring and control range for each operator has expanded significantly. Thus, the objective of the project for operating the facilities with fewer operators was successfully attained.

Promoting the integration of monitoring and control processes to improve operational efficiency on the production floor

SK energy, which originated as Korea Oil Corp., a government-run company established in 1962, is now the largest petroleum and petrochemical company in South Korea. In addition to general petroleum products such as gasoline, kerosene and liquefied petroleum gas (LPG), SK energy supplies diverse petrochemical products to global markets, such as synthetic resins, styrene monomers and ethylene. In recent years, the company has actively been expanding business in the clean energy field by marketing solar cells and lithium ion batteries in response to rapidly growing needs for the reduction of CO2 emissions for global warming prevention. The lithium ion batteries supplied by SK energy are used in hybrid vehicles produced by a Japanese commercial vehicle manufacturer. As such, SK energy offers high-quality products to meet various market needs.

For the past several years, SK energy has been making companywide efforts for the integration of production monitoring and control processes.

“The main purpose of our efforts is to enhance operational efficiency on the production floor and achieve optimum allocation of human resources,” says Mr. Kang. “It is essential for our company to maintain and strengthen competitiveness in global markets.”

Around 2008, aging DCS* needed to be updated. As part of the integration efforts, SK energy decided to use DCS of a single vendor for the three production facilities which had previously been monitored and controlled by DCS of multiple vendors, thus unifying the operator interfaces. Specifically, the company chose to integrate the monitoring and control processes for the production of three petrochemical product groups --- namely heptane, benzene/toluene/xylene and paraxylene.
