Product Description

SYF-1740/150 is a high-performance synthetic gas compressor lubricant based on a poly-alkylene glycol. It is designed for enclosed pattern gas compressors for hydrocarbon and chemical gases where the crankcase and bearings operate in a gas-filled atmosphere. Under these conditions the gas is readily soluble in mineral oil lubricants which, on dilution, suffer a significant drop in viscosity and lubricant performance. This problem can be overcome by using SYF-1740/150 in which the gases are much less soluble. SYF-1740/150 is particularly suitable for marine service on vessels carrying specialist liquefied gas cargoes

Benefits

Reduced gas solubility leading to improved wear protection, extended lubricant life, improved compressor efficiency and Reduced foaming

Multi-gas service for a wide range of gases including vinyl chloride and butadiene. The lubricant does not promote the Dimerisation of butadiene or generate solid deposits.

SYF-1740/150 therefore obviates the need to change to mineral oil for butadiene compression, thus simplifying the lubricant inventory, avoiding mistakes and saving time and expense.

Applications

• SYF-1740/150 is used for the following gases:
• Liquefied petroleum gases such as propane and butane.
• Liquefied natural gases such as methane and ethane
• Hydrocarbon chemical gases such as ethylene, propylene and butylene.
•  Chemical gases such as ammonia, vinyl chloride and butadiene.
