ABSTRACT
One of the most common hazards associated with
production and processing of oil & gas is the
potential for exposure to Hydrogen sulphide.
Hydrogen sulphide is present in oil & gas reserves
in free state as well as in dissolved phase. Upon
a leak from the processing stream, depending
upon the concentration, the released H2S will
pose toxic risk to the ....etc

SYNOPSIS
Development and incorporation of novel technologies to cope up with future challenges are essential for oil companies all over the world to remain competitive in business. In Indian petroleum industry there has been a significant increase in refining capacity during the last decade. However the highest demanded product LPG is still in deficit. The residue up gradation capacity as a percentage of the total refining capacity is poor. Also certain products like naphtha are produced in surplus. Ke ....etc

IMO (International Maritime Organization) is now investigating to include exhaust gas from ships in the objects to be controlled from the viewpoint of environmental protection on a worldwide scale that has been loudly emphasized recently. In case clean methanol is used as fuel, work for handling complicated machines such as centrifuges for heavy fuel oil and for treating sludge discharged from them can be avoided, and further it can be expected to lessen frequent engine maintenance work. It has therefore been strongly desired to use methanol on ....etc

ABSTRACT

In the present paper, efforts have been made to highlight the concept of an INTELLIGENT COOLING SYSTEM. The basic principle behind this is to control the flow rate of coolant by regulating the valve by implementing FUZZY LOGIC.
In conventional process the flow rate is constant over the entire engine jacket. Which induces thermal stresses & reduction in efficiency.
The INTELLIGENT COOLING SYSTEM i.e implementation of fuzzy logic will overcome the above stated drawbacks in any crisp situation. ....etc

Lubrication Systems
Classification of Lubricants
 Animal
 Vegetable
 Mineral
 Synthetic
 Animal Lubricants
Lubricants with animal origin:
– Tallow
– Tallow oil
– Lard oil
– Neat’s foot oil
– Sperm oil
– Porpoise oil
These are highly stable at normal temperatures
 Animal lubricants may not be used for internal combustion because they produce fatty acids
Vegetable Lubricants
 Examples of vegetable lubricants are:
– ....etc

Hello,
I am Avinash, i'm doing my 8th semester mechanical engineering.
I found a ppt on refining of used lubricating oil. I was wondering if some one can help me get a better ppt, about 13 - 15 slides. I don't mean to offend the person who has made that presentation. In that ppt, the last few slides are just pictures, so that doesn't cater to my needs. ....etc

INTRODUCTION
Since the worldâ„¢s resources of material and energy are getting progressively, by necessity, there is growing involvement in studies of wear on a global basis. Wear of sliding components result in reduced mechanical efficiency and an irretrievable loss of material in the form of wear debris. Wear at the interface between moving particles is a normal characteristic of machine operation. The kind and rate of wear depend on the machine type. Lubrication is provided between the moving su ....etc

in this project PLC is used to control the flow of lubricating oil at specified level , this can be done to on bearing, journals and other engine part by installing a transducer near to it , automatically controlling the lubrication of a bearing can be performed either by a stationary installed vibration servo or by measuring the real amount of grease being fed into the bearing . The figure shows a flow transducer unit installed directly in to the grease point. The unit closes/opens a switch which can be used to monitor the real grease flow. ....etc
