PARTHAN PG 150

Application areas:

PARTHAN PG 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

Ideally compression gas should be dry, but this product will tolerate up to 4 % water before becoming hazy at 80°C. Common seal and gasket materials are unaffected by PARTHAN PG Series. Nitrile Rubber (NBR), Fluoro-Silicone or Vinyl-Methyl Polysiloxane are recommended.

Ordinary industrial paints soften in the presence of this product. Two-pack epoxy formulations are normally resistant. This product should not be mixed with mineral oil.

PARTHAN PG 150 is a clear pale yellow viscous liquid with a mild odour.

ADVANTAGE

PARTHAN PG 150 offers the following advantages over mineral oils and competitive synthetic fluids:

• Reduced gas solubility leading to improved wear protection, extended lubricant life, improved compressor efficiency and reduced foaming
• Multigas 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
• PARTHAN PG 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

Special Features

PARTHAN PG 150 is a high performance synthetic gas compressor lubricant based on a Polyalkylene 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 (please refer to attachment giving graph of viscosity/ Pressure) and lubricant performance. This problem can be overcome by using PARTHAN PG in which the gases are much less soluble. PARTHAN PG is particularly suitable for marine service on vessels carrying specialist liquefied gas cargoes.
