公司介绍 (中文):

三星石油化学株式会社（SAMSUNG PETROCHEMICAL CO., LTD. / 삼성석유화학 주식회사）曾是韩国三星集团旗下的重要化工企业。该公司成立于1974年（前身可追溯至此），专注于石油化学产品的生产。

主要业务: 核心业务是生产高纯度对苯二甲酸（PTA - Purified Terephthalic Acid）和单乙二醇（MEG - Monoethylene Glycol）。PTA 和 MEG 是制造聚酯纤维（如涤纶）和聚对苯二甲酸乙二酯（PET，常用于饮料瓶）的关键基础原料。

公司性质: 三星石油化学拥有自己的大型生产基地和制造设施，直接进行化学品的生产和加工。因此，它本质上是一家 制造商（工厂型企业），而非仅仅从事买卖活动的贸易商。虽然其产品会进行销售和出口（涉及贸易环节），但其核心身份是生产者。

重要近况: 需要特别指出的是，三星集团在2015-2016年间对其化工业务进行了大规模重组和出售。三星石油化学的主要业务（特别是PTA业务）被 乐天化学（Lotte Chemical） 收购。因此，目前“三星石油化学株式会社”作为一个独立运营的公司实体在三星集团内可能已不存在或业务已完全转移。其原有的生产设施和业务现在是乐天化学的一部分。

Company Introduction (English):

SAMSUNG PETROCHEMICAL CO., LTD. (삼성석유화학 주식회사) was a significant chemical company under the Samsung Group in South Korea. Established with roots tracing back to 1974, the company specialized in the production of petrochemical products.

Main Business: Its core business focused on the manufacturing of Purified Terephthalic Acid (PTA) and Monoethylene Glycol (MEG). PTA and MEG are essential base materials for producing polyester fibers (like Dacron) and Polyethylene Terephthalate (PET, commonly used for beverage bottles).

Company Type: Samsung Petrochemical owned and operated its own large-scale production sites and manufacturing facilities, directly engaging in the production and processing of chemicals. Therefore, it was fundamentally a manufacturer (factory-based enterprise) rather than solely a trading company that buys and sells goods. While its products were sold and exported (involving trading aspects), its core identity was that of a producer.

Important Update: It is crucial to note that Samsung Group undertook a major restructuring and sale of its chemical businesses between 2015 and 2016. The main operations of Samsung Petrochemical (particularly its PTA business) were acquired by Lotte Chemical. Consequently, "SAMSUNG PETROCHEMICAL CO., LTD." as an independent operating entity within the Samsung Group likely no longer exists or its business has been fully transferred. Its former production facilities and operations are now part of Lotte Chemical.

It's important to note that Samsung Petrochemical Co., Ltd. (삼성석유화학 주식회사) merged with Samsung General Chemicals (now Hanwha Impact) and its assets and operations were subsequently integrated into what is now Hanwha TotalEnergies Petrochemical.

Historically, the main product produced by Samsung Petrochemical Co., Ltd. was:

고순도 테레프탈산 (Purified Terephthalic Acid - PTA)
