Lubrication of Steam, Gas and Water Turbines in Power Generation - a Chevrontexaco Experience
On 9 October 2001 two US oil companies Chevron and Texaco merged. Their long-term joint venture operation, known as Caltex (formed in 1936 and operating in East and Southern Africa, Middle East, Asia and Australasia), was incorporated into the one global energy company. This global enterprise will be highly competitive across all energy sectors, as the new company brings together a wealth of ta...
متن کاملhazard evaluation of gas condensate stabilization and dehydration unit of parsian gas refinery using hazop procedures
شناسایی مخاطرات در واحد 400 پالایشگاه گاز پارسیان. در این پروزه با بکارگیری از تکنیک hazop به شناسا یی مخاطرات ، انحرافات ممکن و در صورت لزوم ارایه راهکارهای مناسب جهت افزایش ایمنی فرا یند پرداخته میگردد. شرایط عملیاتی مخاطره آمیز نظیر فشار و دمای بالا و وجود ترکیبات مختلف سمی و قابل انفجار در واحدهای پالایش گاز، ضرورت توجه به موارد ایمنی در این چنین واحدهایی را مشخص می سازد. مطالعه hazop یک ر...
Water Lubrication of Stainless Steel using Reduced Graphene Oxide Coating
Lubrication of mechanical systems using water instead of conventional oil lubricants is extremely attractive from the view of resource conservation and environmental protection. However, insufficient film thickness of water due to low viscosity and chemical reaction of water with metallic materials have been a great obstacle in utilization of water as an effective lubricant. Herein, the frictio...
متن کاملWater-Based Lubrication Preventing Side Grinding Demonstration in Medium-High Water Cut Wells
In order to extend the pump inspection cycle of the seriously-eccentric-wear well, FU-4 water-based lubricant, which can lubricate the boundary and form chemical reaction film and chemical adsorption film on the tubing and pump sucker rods surface, is synthesized by using water-based lubrication theory for reference which has been widely applied in the fields of cutting, grinding and others fie...
متن کاملSoft lubrication.
We consider some basic principles of fluid-induced lubrication at soft interfaces. In particular, we quantify how a soft substrate changes the geometry of and the forces between surfaces sliding past each other. By considering the model problem of a symmetric nonconforming contact moving tangentially to a thin elastic layer, we determine the normal force in the small and large deflection limit,...
