ATB Ri va Cal zoni
Pressure Pressure V essels Division Thanks to more than 50 years of experience, experience, ATB Riva Calzoni Calzoni has become one of the th e leaders in the design, fabrication and inspection of reactors and heavy wall p ressure vessels utilized utilize d in Oil & Gas, refinery and petrochemical plants operating in the most severe operation conditions of o f pressure and temperature under hydrogen and corrosion attack. In the early 70’s , ATB Riva Calzoni has been the first company in Italy to be qualified by ASME as an authorized holder of S, U and U2 stamps for manufacturing pr essure pr essure vessels for the th e United States market. In the same same years, ATB ATB supplied 12nr hydrocrackers reactors in Cr – Mo material for the EXX EX XON Refinery in Baytown, Louisiana weighing more than 400 t ons each . Since 1960, ATB manufactured more than 1000 pressure vesse ls. manufactured by ATB:

Pressure vessels families
Reactors and Separators for “hydro-processing” applications Ammonia Amm onia shell converte rs and auxiliary vessels Reactors for Urea production plant CCR reactors
Site assembly of high pressure separators and reactors – 2011 [...]
Coke drums High pressure separators and drums for gas treatment plants LNG cryogenic vessels 9%N 9%Nii material Columns (heavy weight) FCCU reactors/ Regenerators IGCC Gasifier vessels LDPE/HDPE LDPE/H DPE separ ators
Supply of 2 Hydrotreating Reactors – 2010 [...]
Reactors and separators for petrochemical plants (Polyethylene /polypropylene, HDPE/LDPE) FCC reactors and regenerators Acrilonitrile reactors Steam Drums
Due to the continuous improvement required by refineries and petrochemical plants productivity, the thickness, diameter and weight of reactors vessels have increased drastically and reached the limits of the current manufacturing technology.

ATB policy is to focus on the most challen ging jobs. Very powerful facilities a nd skilled workers made it possible for ATB to specialize in the manufacturing of pressure vessels of exceptional characteristics. For reference, it has to be considered that up to now ATB has delivered equipment up to 358 mm thickness and maximum weight in one single piece of 1400 tons. The main data can be summarized as follow: Thickness: HC HCK K reactors of 358 mm mm Weight: HDT reactor of 1400 tons Length: C2C3 Splitter Column of 100 m
Supply of 3 Hydrocracker reactors – 2008 [...]

All qualities of steel p roduced to ASTM, DIN, British standar ds and to all western European standards are widely used by the company in the fabrication of pressure vessels, and namely: carbon steel, carbon steel with HIC properties, carbon steel for Low Temperature applications, all the qualities of low alloy steels (1/2Mo, 1Cr 1/2Mo up to 2 1/4Cr 1Mo including the last developments of the materials with enhanced properties and Vanadium modified chemical composition), steels for cryogenic service 9% Ni, stainless steel. In today’s market ATB is worldwide well known as the leading manufacturer of heavy weight and high thickness reactors for hydro-processing applications. During more than forty years experience, ATB has been able to adapt their fabrication technology to follow the customer’s reactors demand both in terms of increasing dimensions, thickness and weight and of upgrading materials requirements The evolution of thickness and weight involved in reactors manufactured by ATB since 1967 is shown in the following diagrams. In today’s market, Hydrocracker Reactors standard manufacturing technology is from forged rings. However a special attention shall be paid to ATB’s capability to manufacture high thickness reactors from both rolled plates and forged ring. ATB is today operating one of the most powerful rolling machine which is enabling us to roll in metallurgical cold conditions plates up to 260mm thickness. The above peculiarity provides to the various engineering companies and end users an higher manufacturing flexibility that in today’s market is a great added value to the traditional manufacturing capabilities. It has to be outlined that in the early sixties ATB was the first company welding 2 1/4Cr 1Mo material and that in the last years, ATB also developed the welding engineering relevant to last generation of Vanadium modified materials such as 3Cr 1Mo 1/4V and 2 1/4Cr 1Mo 1/4V. ATB is now one of the few companies qualified in the world capable to work extensively this V modified materials. For your information ATB, up today first of Q1- 2012, has already delivered 44nr reactors made with this material while other 7nr are currently on order / under fabrications. Site assembly The combination of continuously increasing vessels size/weight with the location of refineries and petrochemical plants makes today more difficult to transport heavy and large equipment to the destination plant. Therefore it is today a common situation to be requested to manufacture the reactors/vessels in sections in shop for an assembly to be made at site In consideration of the above need but without having a dedicated site works divisions, ATB is today one of the company experienced in making such site assembly of pressure vessels. To this purpose we point out our experience made in the 90’s in supervising site assembly of several Acrilonitrile Reactors in Chine for Tecnimont and of FCC Reactor/Regene rator unit in ExxonMobil Sriracha, Thailand refinery. The above experience has further improved in the recent years and in 2002 ATB made the site assembly of a V modified material hydro-processing reactor at PEMEX. Tula refinery, Mexico,. The challenge is today continuing as we are currently involved in two major projects that requires reactors assembly at AGIP S.Nazzaro Refinery, Italy and Flying J Inc. Refinery Bakersfield Ca, Usa. However the above business shall be considered only as an appendix to the reactors shop fabrication and therefore all details conditions shall be carefully agreed so that maximum support shall be provided at site by end users and engineering companies
