Biodiesel refers to a vegetable oil- or animal fat-based diesel fuel consisting of long-chain alkyl (methyl, ethyl, or propyl) esters.Biodiesel is typically made by chemically reacting lipids (e.g., vegetable oil, soybean oil, animal fat (tallow)) with an alcohol producing fatty acid esters.. Biodiesel is a drop-in biofuel and thus meant to be used in standard diesel engines and is thus ...
P art I of this article provided a basic introduction to grease, with discussions of composition, types, properties and evaluation tests. Part II will focus on the correct grease for the application and some of the key criteria in the selection process, including compatibility, amount to be added and relubrication frequency.
The basics Grease is a “dirt magnet,” so it’s surprising to many that packing it into the cavity around the bearing actually helps keep dirt and other contaminants from getting into this critical component. On very old motors, lubrication was provided by oil-soaked felt that “wicked” oil to the bearings.
Paradoxically, the grease gun, designed in 1916 to save bearing lives, has been used to kill them ever since. We can take advantage of this “Lethal Weapon” knowing that by design, a bearing only requires 30% to 50% of its cavity to be filled with grease to provide an optimal lubrication state.

Grease needs to maintain its consistency under high shear conditions. The shear stability test measures the softening of grease when sheared for 10,000 or 100,000 double strokes with a grease worker. Loss of less than one NLGI grease grade signifies a stable thickener under high shear conditions. Compatibility
Wire rope forms an important part of many machines and structures. It is comprised of continuous wire strands wound around a central core. There are many kinds of wire rope designed for different applications. Most of them are steel wires made into strands wound with each other. The core can be made ...
But lubricants come in many types, chemistries and viscosities. From alcohol-thin oil to the thickest, stickiest grease, they all serve important purposes in operating valves. Oils, which are also the base ingredient for most grease compounds, come in many forms. They can be petroleum-, animal- or plant based, or they can be synthetic creations.
More efficient bearing lubrication. August 7, ... Consider that, while some grease points need to be greased weekly or monthly, some grease points might have to be greased once a day, seven days a week. For equipment requiring high-frequency greasing, the time commitment for lubrication could add up to seven to ten and a half hours a week ...
Because oil is always the lubricating medium, all decision factors involved in choosing the right viscosity and additives for the application will still apply. Before using a specific grease, check with the grease vendor or manufacturer to ensure that the product’s oil viscosity is suitable for your application. Grease characteristics
Do you need grease or oil for your bearings? Although there are upsides to both lubricants, you must consider your application. G rease or oil for rolling bearing lubrication helps smooth the way toward reliable performance by preventing metal-to-metal contact between a bearing’s rolling elements, raceways and cages. Besides separating the rolling and sliding contact surfaces in a bearing ...
One of the most important things an operator can do for his machinery is to make sure it is properly lubricated. So what is a lubricant and how does it affect operations when used properly? This article will answer these questions and more by covering the fundamentals of lubrication. We will discuss ...

Ethanol (CH3CH2OH) is a renewable fuel that can be made from various plant materials, collectively known as “biomass.” Ethanol is an alcohol used as a blending agent with gasoline to increase octane and cut down carbon monoxide and other smog-causing emissions. The most common blend of ethanol is E10 (10% ethanol, 90% gasoline).

Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product. After treatment, the treated industrial wastewater (or effluent) may be reused or released to a sanitary sewer or to a surface water in the environment.. Most industries produce some wastewater.Recent trends have been to minimize such production or ...
