Star’s total solution for Huntsman Petrochemicals.<\/p>\n

Huntsman European Petrochemicals is a major manufacturer of bulk commodity chemicals, and produce around three million tonnes of petrochemicals a year from their well-established manufacturing plants based in Teesside in the North East of England.<\/p>\n

Huntsman had a requirement to increase their ethylene liquefaction throughput to meet market demands and so had a need for increased refrigeration capacity. They wanted a customised refrigeration plant to serve an ethylene heat exchanger, using propylene (R1270) as the refrigerant.<\/p>\n

Star Refrigeration designed the plant to cool high pressure ethylene before shipment. The ethylene is cooled using propylene refrigerant on the shell side of the HP ethylene heat exchanger. The propylene refrigeration system was rated to provide approximately 2000kW of capacity when working with a design ambient wet bulb of +19\u00b0C.<\/p>\n

The refrigeration system included an API 619 compliant screw compressor package with lube system and 3.3Kv high voltage EEx\u201dN\u201d drive motor, evaporative condensers, a propylene liquid receiver and a refrigerant economiser connected to the HP ethylene chiller heat exchanger and ethylene knock-out vessel.<\/p>\n

Star Refrigeration worked closely with the Huntsman and FWEL project team to produce a “project specific” refrigeration plant designed for continuous operation and reliability. There were certain specific project requirements requested by the team, including:<\/p>\n

\u2022Plant operational reliability (24\/7)
\n\u2022Designed to PED requirements
\n\u2022All vessels\/pipe work in LT50 carbon steel
\n\u2022Compressor secondary \u201ddry gas seal\u201d for added\u00a0protection and notification of shaft seal wear
\n\u2022Automatic oil recovery
\n\u2022Vibration monitoring system
\n\u2022Use site specified instrumentation
\n\u2022Project specific documentation<\/p>\n
