Saudi Basic Industries Corp (Sabic), the world's biggest petrochemicals group by market value, is buying part of a residential project from Saudi builder Dar Al Arkan for SR741.7 million ($197.77 million), the two companies said Wednesday. Dar Al Arkan, the Kingdom's largest property developer with a $1 billion Islamic bond maturing in July, said it will book gains from the Sabic land sale in the second quarter of 2012. Meanwhile, Engineers at Sabic UK Petrochemicals Limited have improved equipment monitoring in hazardous areas with the help of the next generation of ATEX explosion proof digital cameras. CorDEX Instruments' ToughPIX 2303XP has been adopted by Sabic UK's site engineering team at the company's Teesside petrochemicals plant, which has resulted in significant time savings across a number of projects. Asset surveys, maintenance programmes and fire safety measures are key priorities at industrial sites and high quality digital photography enables engineering teams to work more effectively, ensuring that equipment and systems are running efficiently and safely.
