3 And plant hasdesigned over 500 crackingfurnaces. Since the year 2000,Technip hasdesigned andimplemented7 Mtpa of ethyleneproductionrepresenting 30% of total leader in the Ethylene businessETHYLENE IN OUR DAILY LIFEE thylene, the simplest of olefins, is used as a base product for many syntheses inthe petrochemical industry: plastics, solvents, cosmetics, pneumatics, paints,packaging etc. Today, the demand for Ethylene is over 125 million tons per year with a growthrate of per year. The average capacity of production plants, known as Steam -crackers, has risen from 300 KTA in the 1980's to over 1,000 KTA FOR MEGA-CRACKERSS ince the late 1990's, Technip has strengthened its leading position in the marketfor mega-crackers used for Ethylene production .

4 Most recent achievements include:A large 1,000 KTA grassroots plant, started up in 2007 The world's largest plant (1,400 KTA) on mixed feed, started up in early 20084 grassroots facilities under construction in 2008 including 2 large mega-crackersin Qatar and Saudi Arabia, with a capacity in the range of 1,300 KTA each8 large capacity furnaces in ThailandCENTERS OF EXCELLENCET hanks to its highly qualified process engineers and technicians, Technip hasacquired sound technological expertise and has the ability to design and developproprietary centers of Ethylene expertise based in California, the Netherlands.

5 Italy andFrance, supported by a global procurement network, place Technip one step aheadof the competition and make it the partner of choice for any Ethylene - Kingdom of Saudi Arabia4 ETHYLENEP roprietary furnacetechnologiesSMKTMCOIL TECHNOLOGY FOR GAS FEEDST echnip's SMKTM technology has become the preferred choice of various ethy-lene producers for cracking gas feeds. It is applied in new, large capacity furnaces. Since the end of the 1990's, Technip's SMKTM technology has been installed in 88furnaces, delivering a capacity of million tons per year equivalent to 10% ofcurrent world Ethylene production COIL TECHNOLOGY FOR LIQUID FEEDST echnip's GK technology is applied for liquid feed in new furnaces and for themodernization of existing furnaces.

6 It allows operation on a range of feedstocksfrom naphtha to heavy oils, with high selectivity and long on-stream time. Since the year 2000, Technip's GK6 technology has been applied in 66 furnaces,delivering a production capacity of million tons per , the largest capacity SMKTM furnace is 220 KTA and the largest capacity GK6furnace is 150 KTA. However limits of this technology have not yet been TECHNOLOGYIn the future, plant capacitites are expected to grow beyond 2,000 KTA requiringeven larger capacity furnaces.

7 Technip is ready for these large size furnaces withthe ULTRAFUR technology which integrates decades of its proven proprietary technologies,Technip provides plant operators withethylene facilities that are reliable easy tooperate and maintain, resulting in a veryefficient, cost-saving, olefin unitwith the lowestenvironmentalemission furnace technologiesSPYRO furnace design AND OPTIMIZATIONSOFTWARESPYRO simulates the pyrolysis reactions of the cracking process inside the radiantcoil of an Ethylene furnace together with the complete furnace model.

8 It is appliedfor feedstock selection, process scheduling and production optimisation. It allowsaccurate prediction of yield patterns for feed stocks ranging from gases to heavy(or treated) gas oils at all current operating large number of Ethylene plants run on-line control and optimization systemswith a SPYRO programme embedded in their system software. SPYRO can alsobe applied for stand-alone DETERMINING FACTOR IN PLANT CONFIGURATIONAND REVAMP SCENARISPYRO provides detailed information on yields and furnace availability whichcan also be used to set up revamp scenari for the furnace and downstream sectionsof the optimum design of large capacity GK and SMKTM furnaces, Technip appliesSPYRO linked with CFD (Computational Fluid Dynamics)

Since itsintroduction in 1978,SPYRO has beenadopted by 80% ofethylene - Assaluyeh6 ETHYLENEP roprietary separation technologiesACETYLENE ELIMINATIONE thylene plant operators aim at a very pure output from Steam crackers: , with a very low content (below 1ppm) of extremely reactive moleculessuch as acetylene.

10 To achieve this, Technip has developed a sophisticated sequence of separationand purification of the high value products in the Steam methods of acetylene elimination are currently implemented:Front-end hydrogenationcoupled with either front-end deethanizer or front-end depropanizer is available for gas or liquid crackers. This technology is beingapplied in the plant currently under construction in Kuwait. Back-end hydrogenationcoupled with front-end demethanizer is applied foreither gas or liquid crackers.
