Strengths of NP process
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.
Features and Advantages of SS Process
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.
Features and Advantages of TDM Process
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.
Features and Advantages of IPA Process
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
Features and Advantages of LAB Process
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
Features and Advantages of BAB Process
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
