I.4. Refinery Module

Modular Experience

A modularization strategy offers ascendant advantages versus on-site manufacturing. During the

last 40 years, PROSERNAT has supplied over 400 modular units, both onshore and offshore,

providing tailor made designs based on inlet feed conditions and guarantying outlet specifications.

Refinery Modular Experience

Modularization Concept

Based on process design performed by PROSERNAT’s sister company AXENS, PROSERNAT

offers complete modular refinery units for all kind of applications.

Why to choose Modules ?

The delivery of a complete skid-mounted module is a key choice in the following contexts:

Refineries with complex access and a lack of manpower

Restricted plot areas for installation of new units

Minimize disturbances of ongoing operations

PROSERNAT Advantages - PROSERNAT modules offer the following advantages:

Shortened schedules: a 25% schedule reduction is usually achievable during project

execution when modular construction is considered. The major schedule reduction is

obtained because construction can be performed at the same time as the construction phaseon-site. By the time the modular unit reaches the owner’s site, the field is ready for module

installation and connection with existing facilities.

Cost savings: by maximizing workshop construction and assembly, full advantage is taken

from an efficient and organized work progression. 40 to 100% higher labor productivity isusually achieved and supervision time with a trained manpower is generally reduced by

25%. Cost savings are also achieved on field, where a modular unit requires less plot areaand simpler foundation than a similar stick built unit.

Improved safety requirements: most of the labor intensive tasks are achieved in a workshop

or on a yard chosen for its favorable and efficient working conditions. Construction permits

are not necessary and there is no interaction with ongoing site operations, it greatly reducesowner’s safety concerns.

II.3. Gas Dehydration

II.3.1. TriEthylene Glycol

Water absorption with TriEthylene Glycol (TEG) is a very well known and proven technology. It

is the most common process used for gas dehydration. PROSERNAT has supplied about 100 TEG

units during the last 35 years.

Process Principle

The water contained in the gas to be treated is absorbed counter-currently by lean TEG in a

gas/glycol contactor. At the bottom of the contactor, the rich TEG (containing the absorbed water)

is sent to the regeneration section where water is vaporized in a Reboiler at low pressure (close toatmopheric pressure).

Depending on the requested lean TEG purity, the lean TEG produced in the reboiler can be either:

Pumped directly to the gas/glycol contactor (low TEG purity required)

Stripped with stripping gas before being pumped to the gas/glycol contactor (high TEG

purity required)

Industrial Experience

Three TEG units - 3 x 300 MMSCFD - UAE

requirements


27/54


28/54



28

Range of Processes

The more common desiccants used are:

Molecular sieves: used to achieve very low water dew points, from -100°C for ethane

extraction units up to -160°C for the liquefaction of natural gas

Activated Alumina: compared with molecular sieve, it provides better adsorption capacity

at high partial pressure of H2O but a lower capacity at low partial pressure. Activated

alumina is used when the amounts of water to extract are important and dew points not toodifficult to reach (about -60°C). A combination molecular sieve / activated alumina to

minimize the amount of adsorbent can be an option when it is required to simultaneously

extract large quantities of water and achieve very low dew point.

Silica Gel: proven adsorbent which has a high water adsorption capacity, but which cannot

be used to achieve very low dew points. Silica Gel are also used to remove heavyhydrocarbons (C4 +) together with water (combined hydrocarbon and water dew points).

Key Benefits

A very well known and proven technology

A process reliable and easy to operate

A process offering high flexibility

A good selectivity (coadsorption can be avoided)

Very low water dew point can be reached (below 0.1 ppm water content).


29/54



29

II.3.3. Drizo™

With more than 60 references to date, Drizo™ has proved to be the best available glycoldehydration process. This is not only because of its higher dehydration efficiency, but Drizo™ is

also an environmentally friendly process with minimized BTEX / CO₂ emissions. Thanks to the

minimal number of additional equipments specifically required by Drizo™ compared toconventional glycol units, the process has easily been implemented on existing glycol units, at

minimal cost and with no shutdown time.

Process Principle

Drizo™ regenerates the glycol by solvent stripping instead of the conventional gas stripping.

Solvent stripping allows to obtain much higher glycol purities than gas stripping (up to 99.998

wt% instead of the typical 99.95 wt%) and consequently allows to get much larger water dew pointdepressions: up to 100°C (180°F) and even higher in some cases. The solvent required by the

Drizo™ process is usually obtained from the BTEX present in the natural gas itself and in most

cases, the process will even produce some liquid hydrocarbons. Glycol solvent stripping by

condensates (instead of conventional gas stripping) allows:

Higher glycol purities down to < 1 ppmv H2O in treated gas

Reduced BTEX / CO2 emissions

Possible recovery of liquid aromatics

Drizo™ solvent is not a solvent, it is a hydrocarbon recovered from feed gas

Key Benefits

A proven technology, with more than 60 references

A process easy to operate and offering high flexibility

The cheapest technology for very low water dew points. Dew point depressions to -

110°C / -200°F

Suitable to retrofit conventional glycol regeneration unit at minimal CAPEX

Below ppm gas dehydration performance

Environmentally friendly installations, with reduced BTEX / CO2 emissions and liquid

aromatics recovery


30/54

II.3.4. Ifpexol™

Ifpexol™, a two steps integrated process for complete natural gas treatment with methanol.Ifpexol™ is a patented technology of simultaneous dehydration and hydrocarbon dew point

control. Methanol is regenerated from the cold decanted water by stripping.

Process Principle

Ifpexol™ uses refrigerated methanol for the complete treatment (dehydration, NGL recovery and

sweetening) of natural gas. The Ifpexol™ process is based on two independent steps:

Ifpex-1 for simultaneous water and hydrocarbon dew pointing

Ifpex-2 for acid gas removal

Methanol is used as hydrate inhibitor in a cold process for NGL extraction. The mixture of

methanol and water recovered at the low temperature separator is regenerated by simple stripping

with a fraction of the feed gas and pure water is produced.

Performances

Over 99.9 % stripping effectiveness with raw gases at pressures as high as 100 bar.

Water dew point as low as -80°C.

Adequate mass transfer contact between methanol-water liquid stream and stripping vapor

stream.

No hydrate formation or icing concerns (Methanol is recirculated as a hydrate inhibitor andantifreeze agent)

No venting

No need for external heat

No dangerous waste streams

Key Benefits

Ifpex-1

Minimized CAPEX if cold process is available

MeOH recovery from NGL’s by water wash (optional)

34/54



34

II.3.6. Progly™

Progly™ is a glycol dehydration process very similar to a conventionnal TriEthylene Glycol(TEG) unit. The main improvement of this technology is the vacuum operating mode of the

distillation column. Thanks to the minimal number of additional equipments specifically required by Progly™ compared to conventional glycol units, the process has easily been implemented on

existing glycol units, at minimal cost and with no shutdown time.

Process Principle

Progly™ is similar to a conventionnal TriEthylene Glycol (TEG) unit with the main following

change : the stripping column is replaced by a flashing drum that operates under partial vacuum,

in order to perform deep regeneration of the TEG.

The arrangement of the unit allows to operate only few equipments under vacuum: as per a

conventionnal unit, the reboiler and the still column operate under positive pressure.

Process Scheme


35/54

II.7. Compression

Compression is an essential step in the frame of natural gas handling. Wheither it be for gas

transportation purpose, storage or upstream of treatments, compression is most of the time required

in Oil & Gas projects.

Industrial References

The picture below shows the balance of plant for 5 compression trains (2 LP + 3 HP) for Filanovsky

Central Processing Platform (end user : Lukoil) for which PROSERNAT scope was fullengineering (basic and detailed), procurement and skids fabrication of 3 TEG packages with

regeneration, a fuel gas package and a balance of plant for 5 compression trains including F&G

detection, deluge, MCC with Delivery FCA of skids, pre-fabricated parts - mix packages and loose.

47

Process Principle

Compression systems involve compressors together with process pieces of equipment such asseparators and coolers. Depending on the application, several technologies may be chosen to meet

project requirements. Compressors may be of several types (centrifugal, reciprocating, screw,…)

when different technologies may be chosen for separation and cooling of the process gas.

PROSERNAT Advantages

PROSERNAT has many industrial references for compression application and offer the following

advantages :

Engineering and supply of process components (scrubbers, interstage coolers,…) for gas

compression modules / stations Selection of appropriate separation technologies for compression station balance of plant

II.8. Offshore / Floating

Offshore and Floating Oil & Gas production plartforms are always a challenge. Thanks to its

extensive know-how in the field of gas treatment and its important investment in Research andDevelopment, PROSERNAT has the ability to undertake any offshore engineering constraint and

specification, providing custom made equipments for a complete range of treatment processes.

Modular Strategy

Any type of processing unit which is used onshore can technically be implemented offshore.

PROSERNAT has worked a lot on modularization concept to offer optimized process solutions

for offshore and floating environment. Our units are designed to answer offshore key drivers :

weight, size and motion.


49/54



49

Environment Challenges

When installing a unit offshore, the following aspects are to be taken into consideration :

Weight is critical

Footprint has to be reduced

High installation compactness impacts safety requirements

Maintenance and logistic are an issue

Offshore treatment is always more expensive than onshore

Offshore constraints will affect process selection and design

As an expert in custom made solutions supply, PROSERNAT proposes specific offshore

engineering focusing on these project key drivers.

Experience and Research

PROSERNAT has more than 55 references offshore. By holding its own processes together withcomplete engineering capabilities from basic design up to construction supervision, this makes

PROSERNAT a reliable supplier, able to offer tailored and optimized solution to meet offshore

and floating units design and procurement specifications. PROSERNAT R&D programs includeinnovative developments with the aim of adapting process and units design to offshore and floating

:

High pressure redox SweetSulf™ process for selective H₂S removal and conversion into

solid sulphur: MDEA and acid gas treatment replaced by a single process step Ifpex-2, autothermal scheme for bulk CO₂ removal and reinjection: no thermal

regeneration, no external refrigeration, CO₂ is recovered dry and under some pressure

Amine based processes: development of new liquid distributors to reduce column height

and enhance performances under moving conditions for floating applications

II.9. Modular Experience

A modularization strategy offers ascendant advantages versus on-site manufacturing. During the

last 40 years, PROSERNAT has supplied over 400 modular units, both onshore and offshore,

providing tailor made designs based on inlet feed conditions and guarantying outlet specifications.

Modularization Concept

The purpose of modularization is to provide a completely prefabricated skid-mounted unit, thus

minimizing site works. One unit is composed of several interconnected modules, one module iscomposed of several assembled skids. Module construction is performed in a workshop or yard

remote from the final project site and equipped with adapted manufacturing and personnel

capacities.

Why to choose Modules ?

The delivery of a complete skid-mounted module is a key choice in the following contexts:

Remote areas, with complex access for construction means and lack of manpower

Extreme climates, where working possibilities are restricted by seasonal constraints

Lack of labor quality and availability

Offshore sites, where on-site manufacturing is hardly possible and plot area optimization

is compulsory

Existing plants, where on-going operations are an obstacle to safe on-site manufacturing

PROSERNAT Advantages - PROSERNAT modules offer the following advantages:

Shortened schedules: a 25% schedule reduction is usually achievable during project

execution when modular construction is considered. The major schedule reduction isobtained because the module construction can be performed at the same time as the

construction phase on-site. By the time the modular unit reaches the owner’s site, the field

is ready for module installation and connection with existing facilities.

Cost savings: by maximizing workshop construction and assembly, full advantage is taken

from an efficient and organized work progression. 40 to 100% higher labor productivity is

usually achieved and supervision time with a trained manpower is generally reduced by25%. Cost savings are also achieved on field, where a modular unit requires less plot areaand simpler foundation than a similar stick built unit.

Improved safety requirements: most of the labor intensive tasks are achieved in a workshop

or on a yard chosen for its favorable and efficient working conditions. Construction permitsare not necessary and there is no interaction with on-going site operations, it greatly reduces

owner’s safety concerns.
