Petrochemicals and AI
Creating a sustainable petrochemical industry depends on being able to measure performance in precise terms . Aramco and IBM are setting up an innovation hub in Saudi Arabia that will address issues such as the circular economy , material discovery , sustainability , supply chain , digitalisation and artificial intelligence , using technologies in hybrid cloud , AI and quantum computing .
severe than in other industries , and pressures and heat are also elevated . The full range of austenitic and superaustenitics are used , but duplex and super-duplex grades are required for the toughest conditions . A new high-alloy super-duplex grade , SAF™ 3006 , has recently been developed specifically for heat exchangers in the chemical and petrochemical industries . It will complement SAF™ 2507 , introduced by Alleima in 1985 and designed to handle mainly chlorides , whereas SAF™ 3006 has been fine-tuned to handle hydrochloric , sulphuric , formic or other acids .

Another Alleima product , Sanicro ® 35 , combines the best features of superaustenitics and nickel alloys and can be used in chemical processing , oil & gas and other industries . Duplex also plays a role in the production of urea , which is used as a source of nitrogen in the manufacture of fertilisers as well as serving as a raw material in the chemical industry . Stamicarbon has recently built several of its Ultra-Low Energy urea plants , which use high-pressure equipment for the melting and prilling processes . This design applies the Ultra-Low Energy principle to the pool condenser , superseding the pool reactor technology used previously . The new design allows heat supplied as high-pressure steam to be used three times instead of two , reducing steam consumption by about 35 % and cooling water consumption by about 16 % compared to the traditional design . The pool condenser is made of Safurex ® , a super-duplex stainless steel developed by Sandvik ( now Alleima ), specially designed to handle extreme corrosion ( from ammonium carbamate ), heat and high-pressure . Recent examples of its use are in a series of plants announced by Stamicarbon in 2023-4 : in Jiangxi province , China ; Zhangjiagang City , Jiangsu province , China ; the African Sub-Sahara ; Cairo ; Shouguang , Shandong province , China ; and the USA .
Oliver Twinsafe supplies Double Block and Bleed pipeline valves for use on monoethylene glycol ( MEG ) injection pump systems . They are in in A182 F55 super-duplex grade ( 25 % Cr , but with added tungsten ) that have been dynamically tested to meet the requirements of API 6A PSL level 3 .
