Phase behaviors of lithium soap/synthetic oil greases.

Journal of The Japan Petroleum Institute, 1980
The phase behaviors of lithium soap/synthetic oil greases have been investigated by differential thermal analysis (DTA). The phase transition temperatures of the greases prepared with di-2-ethylhexyl sebacate and pentaerythritol tetraoctanoate were affected hardly by the atmosphere in which the grease was prepared.

Tribology of 2-Mercaptobenzothiazole in Lithium Complex Grease

, 2011
There has been no much difference in usage pattern of EP/antiwear additive chemistry of additives in greases and other lubricants like cutting fluids and gear oils. These additives perform very well in some greases but not able to perform up to desired level in other applications. Due to high active sulfur content, they need supplementary additive with

Systems-Level Optimization of Hybrid Produced Water Treatment Systems for Sustainable Oil and Gas Production: A Review of Current Technologies. [PDF]

Glob Chall
ABSTRACT Produced water (PW) is the largest and most complex waste stream generated during oil and gas production, posing significant environmental, operational, and regulatory challenges due to its high salinity, dispersed hydrocarbons, toxic organics, heavy metals, and naturally occurring radioactive materials. Although numerous studies have reviewed
