The lubrication system of an internal combustion engine serves many purposes. It lubricates moving parts, cools the engine, removes impurities, supports loads, and minimizes friction. The entrapment of air in the lubricating oil is called oil aeration. Oil aeration can be detrimental to internal combustion (IC) engines. This study attempts to determine a means to reduce the level of aeration in...

Design and manufacturing technology of high pressure multistage pumps which are commonly utilized in oil and gas industries, used to be imported from foreign companies. Due to international sanctions against I. R. Iran, it started to be designed and launched domestically. Nowadays all production lines including design, manufacturing and testing of these pumps have been performed by Iranian expe...

Oil and gas production in Indonesia keeps declining while consumption increases, resulting being a net oil importer since 2004. The problem that is faced by many producers right now the mature field with an aging facility frequent unplanned shutdowns could jeopardize production. If not responded to promptly adequately, lose its This one of challenges PT ABC are facing. study will present invest...

Due to the periodic movement of the piston in the reciprocating pump, the fluid will cause 8 pressure pulsation, and the vibration of the pipeline will lead to instrument distortion, pipe failure 9 and equipment damage. Therefore, it is necessary to study the vibration phenomena of the 10 reciprocating pump pipeline based on the pressure pulsation theory. This paper starts from the 11 reciproca...

Oil shale is a sedimentary rock that contains kerogen, a fossil organic material. Kerogen can be heated to produce oil and gas (retorted). This has traditionally been a CO2-intensive process. In this paper, the Shell in situ conversion process (ICP), which is a novel method of retorting oil shale in place, is analyzed. The ICP utilizes electricity to heat the underground shale over a period of ...

Contamination in hydraulic systems is the cause of 70% failures. This study highlights performance degradation caused by solid particle contamination components: gear pump, 4/3 valve, and orbital motor. Experimental durability tests components with wear particles test dust are used to investigate effects accelerated these two types contaminants. Results show that oil contaminated reduces volume...
