NPNP : Normal Paraffin

Strengths of NP process

- Production of high quality normal paraffin (Purity level 99.8%)
- Meet customers need and create economical efficiency by the adjustment of production quantity.
- Manufacturing of main raw materials for LAB products

Raw Material Storage

Store kerosene, the main raw material of Normal Paraffin, received from S-Oil.

Fractionation Distillation

The raw material is transferred from Feed Tank and pre-heated. in the column, the light cut is fed into overhead and the Bottom into the Hydrotreating Unit.

Add Hydrogen HYDROTREATING

By adding hydrogen to KEROSENE, the sulfur, oxygen, and nitrogen compounds that lower the ACTIVATION of MOLECULAR SIEVE in the MOLEX UNIT are removed.

Hydrogen unit

Rerun Colum

The column that removes the Heavy oil in Kerosene. in the Feed, the oil that has high boiling point is separated at the Bottom and sent to the heavy Cut storage, the overhead oil is fed into the Molex process.

Molex Extracting Process

The selective extracting process of Normal Paraffin and Raffinate in the Molex Unit, among the Kerosene inflow from the Hydrotreating Unit.

Post

The process in which Normal Paraffin inflow from Molex is sorted by the Carbon Grade.

SS ProcessSS : Special Solvent

Features and Advantages of SS Process

- Outstanding safety of no color, ordor or poison
- Better solvency than Paraffin by containing Napthene
- Convenient use of the product by removing Aromatic and Sulfur
- Fast delivery on customer's demands by constructing a small batch production system

Raw Material Sorage

Store Crude Oil, the raw material for SS products.

Reaction Effect

Effect Crude Oil and H₂ at appropriate temperature and pressure and remove Aromatic.

Fractionation Distillation

Produce the SS product meeting customer's needs through Distillation.

TDM ProcessTDM : Tertiary Dodecyl Mercaptan

Features and Advantages of TDM Process

- Control molecular weight in mass molecular synthesis such as ABS, Isoprene, SBR.
- Reacts to H₂S, the byproduct of H₂ process.
- Production system constructed by self-developed technology.
- Environmentally friendly product that contributes to the mass promotion of global export.

Raw Material Storage

Store Propylene Tetramer, the Raw materials for TDM products.

Reaction Effect

Effect the raw material and the H2S, the byproduct of NP process at appropriate temperature and pressure.

Fractionation Distillation

produce the TDM product meeting customer's needs through Distillation.

IPA ProcessIPA : Iso Propyl Alcohol

Features and Advantages of IPA Process

- Acetone Base product
- Competitive price advantage compared to Propylene Base IPA
- Reduced domestic import of industrial IPA
- Future potential in entry of electronic IPA market with the accumulation of know-how
- Process development and patent rights through self-reliant technology

Raw Material Storage

Store Acetone, the raw material for IPA products

Reaction Effect

Effect Acetone, and H₂ at appropriate temperature and pressure

Fractionation Distillation

Produce the IPA product meeting customer's needs through Distillation

LAB ProcessLAB : Normal Paraffin

Features and Advantages of LAB Process

- Flexible process conditions for manufacturing of products according to
- It minimizes the BI(Bromine Index) figure and the alkylate content in C9-, C14 which may affect LAS as LAB downstream.

Raw Material Storage

A process necessary for stable supply of Normal Paraffin, before transferring to the Pacol process.

Pacol

A dehydrogenation process that heats the Normal Paraffin inputs at a temparature range of 470~484℃ and transports it through the Pacol Reactor to convert it to Olefin.

Alkylation

The Olefin produced through the dehydrogenation process is reacted with Benzene in order to produce Alkylate.

Fractionation

The Benzene, excessively added in Alkylation, and the NP residual after dehydrogenation are separated by distillation. These are recycled to alkylation process and base material tower. The final remnant of Alkylate is separated according to the specification at the Distillation column.

Export Terminal

BAB ProcessBAB : Branched Alkyl Benzene

Features and Advantages of BAB Process

- Flexible process condition for the manufacturing of products that customers want.
- Heater source of the process is replaced from Fuel Oil to LNG (2004.10) thereby increasing Heater efficiency and improving air quality.

Raw Material Storage

The process that removes dissolved oxygen and humidity by inputting Propylene Tetramer and Benzene into the Feed Drying Column

Alkylation

Process to react Propylene Tetramer with Benzene under HF catalyst, thus resulting in production of Alkylate

Fractionation

Separate the created Alkylate according to the specification at the Distillation Column
