1. INTRODUCTION
1.1 Unit Processing Objectives
The Naphtha and Aromatics Complex shall be designed to process a stabilised
feedstock of full range naphtha with the following objectives:
• To maximise Paraxylene yield for product sale.
• To produce a yield of Benzene for product sale.
• To recover Liquefied Petroleum Gas (LPG) from the CCR Platforming Unit.
• To produce an Isomerate stream for gasoline blending
• To produce a hydrotreated light and heavy naphtha stream to control the
feedstock quality to the aromatics and isomerate producing units.
• To produce Hydrogen at (99.9% mole) purity for use on other refinery units.
• To have the facilities to route Toluene or HA column overheads to gasoline
blending, if required.
The overall design philosophy of the Naphtha and Aromatics Complex maximises
economic Paraxylene production.
1.2 Use of Document
This document shall be used as the basis for the process design of the Naphtha
and Aromatics Complex only.
The design requirements specified in this document are considered to be the
minimum required. Where Licensor is applying more onerous requirements or
more beneficial operation than those specified, these shall be notified to Employer
prior to implementation.

3. UNIT DEPENDENCE
The Naphtha and Aromatics Complex shall be capable of operating independently
subject to the availability of hydrocarbon feedstocks, hydrogen make-up and
utilities.
Sufficient intermediate storage capacity will be available to enable continued
production of Paraxylene and Benzene products in the event of either Naphtha
Hydrotreater unit or CCR short term outage, and continued operation of the
Naphtha and Aromatics Complex during short term outage of the CDU and LPG
Recovery Unit.
Paraxylene and Benzene products shall rundown cold to Product Storage.
Isomerate shall rundown cold to Product Component Storage. Heavy Aromatics
shall rundown cold to Fuel Oil Blending storage. Toluene and A9/A10 Aromatics
shall normally be direct hot feed for the Tatoray Unit but shall also have the
facilities to rundown cold to Product Component Storage.
The following Intermediate, Product, and Product Component Storage Tanks will
be available and are excluded from Licensor’s scope:
• FRN (Full Range Naphtha) Tanks
• Desulphurised Heavy Naphtha Tank
• Reformate Tank
• Light Reformate Tank

• Heavy Reformate Tank
• Isomerate Tanks
• Heavy Aromatics Tanks (Toluene and A9/A10 Aromatics)
• Paraxylene Storage Tanks
• Benzene Storage Tanks
• Refinery or Utility Fuel Oil Tanks
The Naphtha and Aromatics Complex will normally operate with 100% hot direct
feeds to maximise energy efficiency, but provision shall be made to accept partial
or entire feed 'cold' from storage whilst meeting all product specifications.
Similarly, Naphtha and Aromatics complex intermediates are normally rundown
hot to the downstream units, but provision shall be made for intermediates to run
down cold to available storage.
LPG from the CCR shall be routed to the De-ethaniser in the LPG Recovery Unit
(outside the scope of Licensor). Offgas from the NHT shall be fed to the LPG
Recovery Unit (outside the scope of Licensor).
The battery limit conditions required for each intermediate, product and by-product
are outlined in Section 5 below.

4. BASIS OF DESIGN
4.1 Design Objective
The Naphtha and Aromatics Complex shall be designed to process a full range
naphtha feedstock to produce Paraxylene and Benzene products at a purity
suitable for sale and an Isomerate stream suitable for gasoline blending.
The CCR of the complex will produce hydrogen with a purity of 99.9 mol% that will
be routed to the refinery Hydrogen Compression and Distribution System for use
throughout the refinery.
LPG from the CCR shall be routed to the De-ethaniser in the LPG Recovery Unit.
The design philosophy of the Naphtha and Aromatics Complex is to maximise
economic Paraxylene production. Benzene is treated as a paraxylene by-product
and is 2
nd
priority. Benzene production should float in favour of paraxylene.
There is no target for Isomerate production volume, the isomerate production
volume can decrease in favour of paraxylene and benzene production.
Production of Heavy Aromatics should be minimised to obtain further paraxylene
and benzene production.
4.2 Design Capacity
The Naphtha and Aromatics Complex shall be designed to process the following
quantities of the design feedstock.
Table 4-1: Feedstocks to the Naphtha Hydrotreater
Feedstock
Flow rate, te/
stream day
Full Range Naphtha 5500
The properties of the above feedstock are listed below in Table 4-2 below.
4.3 Design Feed Cases
The design feed case for the Naphtha and Aromatics Complex is 100% straight
run naphtha with the feed specifications as shown in Table 4-1.

For the Naphtha Hydrotreater, an alternative (C4 spike) design case is required for
the design of the Naphtha Stripper and associated equipment. The basis for the
C4 spike case is 1 vol% of C4 in the feed.
An additional (rich) design case for the CCR Platforming Unit is required. The
basis for the Rich feed case is 10% additional Naphthenes (on a PONA basis) in
the CCR Platforming Unit feed.

The Naphtha and Aromatics Complex will normally operate with 100% hot direct
feed from the LPG Recovery Unit to maximise energy efficiency, but provision
shall be made to accept partial or entire feed 'cold' from storage whilst meeting all
product specifications. The design basis for Hot and Cold Feeds is provided in
section 4.7.4 below.
The feedstock pressures and temperatures are provided in section 5 below.
Properties of the Naphtha and Aromatics Complex feedstock are given in Section
Table 4-2 below.
It should be noted that the Licensor may be requested, during the Licensor PDP
phase, to provide estimates of product yields and main properties, operation
conditions, probable bottlenecks (identification of constraining equipment) and

maximum throughput for various Performance Cases. These Performance Cases
may concern feeds or operating objectives different from the Design Case.
4.4 Feedstock Properties
The design properties of the 100% straight run, full range naphtha feedstock to the
Naphtha and Aromatics Complex, processed from Kuwait Export Crude, are
detailed in Table 4-2 and Table 4-3 below.
