Software optimizes usage of full-containment storage tanks

| By Mary Page Bailey and Gerald Ondrey

This company has enhanced its Rosemount TankMaster inventory-management software package (photo) to help optimize tank usage and increase safety in full-containment storage tanks for liquefied natural gas (LNG) and other liquefied gases. These tanks are large, complex structures with a typical capacity of up to 200,000 m3, which places specific demands on tank-gauging systems. By providing both inventory management and roll-over prediction in a single software solution, TankMaster reduces both cost and risk, says the company. Roll-overs are dangerous releases of boil-off vapor that can occur when LNG stratification is left unchecked. The consequences can be severe — including extensive tank damage and the release of large quantities of LNG into the atmosphere. TankMaster software uses data from level, temperature and density measurement devices incorporated into the Rosemount Tank Gauging System to calculate when a roll-over might occur, enabling operators to take preventative action. — Emerson, St. Louis, Mo.
