Essar Heavy Engineering Services (EHES) has fabricated its first single-piece Liquid-Liquid Separator for a global oil & gas major. A Liquid-Liquid Separator is a critical piece of machinery in a refinery because it helps separate fluids into gaseous and liquid components before the production of the refined product. The 150-tonne unit is among the largest ODC (Outer Diametre Circumference) vessels used in a refinery, with a diametre of 7.2 metres and a length of 28.2 metres. The vessel is built with steel manufactured at Essar Steel’s state-of-the-art Plate Mill in Hazira.
Established in 2005, EHES is a modern fabrication facility operated by Essar Projects in Hazira. It has a strategic waterfront location that gives it access to a captive port, enabling quicker and cheaper turnaround by way of rapid sea logistics. EHES can manufacture heavy equipment for varied industries, including sectors related to Fertilisers, Oil & Gas, Petrochemicals, Power, Steel and Ports. The fabrication of the Liquid-Liquid Separator highlights EHES’ world-class capabilities and positions it among the leading international manufacturers of large ODC vessels.
The Separator has been fabricated in accordance with ASME (American Society of Mechanical Engineers) standards. In fact, the process was reviewed both by an ASME-authorised inspector and the client. In addition to the criticality of physical dimension, the making of the equipment is an achievement even from a process perspective. The sub-components of the unit have differing metallurgical compositions—both carbon steel and non-ferrous alloys were used. Despite such non-standard metallurgical combinations of ferrous and non-ferrous elements, the unit was able to withstand variations in design temperature up to a maximum of 260ºc.
