Butadiene - 60,000 Mt/y

Capacity: 60,000 Mt/y
Technology: Dmf Solvent Nippon Zeon Process
Year Built: 1988
Year Shut: 2003
Raw Materials: C4 Fraction, Dmf

Overview / Process Details:
The Complete Butadiene Plant Was Built In 1988 And Operated Until 2003. It Is Based On Dmf Solvent Nippon Zeon Process Technology With A Capacity Of 60,000 Mt/y. The Plant Processes The C4 Fraction Through An Initial Extractive Distillation Using Dimethylformamide (dmf), By Separating The Butylenes And Butanes From The Butadiene And Acetylenics. With A Second Extractive Distillation It Separates The Vinyl Acetylene, And Finally, Through A Rectification Process, It Separates The Methyl Acetylene And The Heavy Hydrocarbons From The 1,3-butadiene (butadiene). These Three Main Sections Are Combined With Others Using Vessels To Purify The Solvent And To Additivate The Processing Of Various Chemicals From A Condensation Water Circuit, From A Tower Water Circuit And From A Flare And Draining Header. The Produced Butadiene Has A Minimum Title Of 99.6%. A Recovery Of 98% In Weight Is Expected In The Project Conditions Compared To The Inflowing Butadiene With C4 Fraction.

Major Equipment:

(10) Columns For Distillation, Stripping, Fractionation
(10) Compressors
(28) Tanks-various
(approx. 40) Heat Exchangers-various
(approx. 50) Pumps

Major Upgrades: Dcs System

Carbon Monoxide
Capacity: 25,000 Scfh
Technology: Hydro-chem
Year Built: 1998
Year Shut: 2000

Overview / Process Details:
Design Flow Rate: 24,930 Scfh (carbon Monoxide) Pressure: 440 Psig Temperature: 38 C° Design Flow Rate: 79,087 Scfh (hydrogen) Pressure: 30 Psig Temperature: 10 C°

Additional Info:
Catalytic Reforming Of Steam/hydrocarbon Mixture The Hydrodesulfurized Feed Gas Is Mixed With A Controlled Amount Of Steam. The Mixture Flows Through The Catalyst Tubes In The Reformer Furnace F-700. The Reformer Furnace Is Cylindrical In Design With Catalyst Tubes Arranged In A Circle Near The Insulated Refractory Wall. Flow In The Tubes And Firing Of The Furnace Are Both Upward. The Reforming Furnace Is The Heart Of The Hydrogen Production Plant. The Reaction Of Hydrocarbon Gas With Excess Steam In The Presence Of A Nickel Reforming Catalyst Produces Hydrogen, Carbon Oxides, And Methane. The Reforming Reaction Is Highly Endothermic (i.e., Requires A Large Heat Supply) And Must Take Place Under Carefully Controlled External Firing Conditions. In Addition To The Reforming Reaction, A Partial Water Gas Shift Reaction Occurs In The Reformer Furnace. Process Gas Leaves The Reformer Catalyst Tube At Approximately 800°c - 830°c (1475°f - 1525°f). Flue Gases Leaving The Reformer Furnace Are Used To Superheat The Process Steam And Feed Gas Before It Enters The Reformer Tubes And Also To Produce Steam And To Heat (economizer Xc-710) The Boiler Feedwater For The Steam Generators B-710 And Xc-700.
