Hastelloy Alloys Hastelloy alloy is a corrosion-resistant nickel (Ni) alloy which contains other chemical elements such as chromium (Cr) and molybdenum (Mo). This material has high temperature resistance and outstanding corrosion resistance. Hastelloy alloy has good sulphfidation resistance and high metallurgical stability, which makes it preferable material for high-temperature applications of thermal energy storing and electricity generating devices such as gas …
Read MoreOperation and Maintenance Manual A comprehensive ‘operation and maintenance’ (O&M) manual for an equipment / facility hereto referred as ‘plant’ is necessary for the smooth operation of the plant. The O&M manual serves as an important tool for existing and new employees to safely and successfully operate and maintain the plant. When put together properly, …
Read MoreAmmonia Recovery from Coke Oven Gas The coke oven by-product plant is an integral part of the by-product coke making process. In the process of converting coal into coke using the by-product coke oven, the volatile matter in the coal is vapuorized and driven off. This volatile matter leaves the coke oven chambers as hot, …
Read MoreIndustrial Fans and Blowers Fans are normally identified as machines with relatively low pressure rises which move air, gases, or vapours by means of rotating blades or impellers and change the rotating mechanical energy into pressure or work on the gas or vapour. The result of this work on the fluid is in the form …
Read MoreOrganizational Policies and Procedures Organizations are described as a form of association, wherein men, material, and other resources are engaged for the purpose of accomplishing a desired objective. The term organization is derived from the word ‘organicism’, which means an organized body of interdependent parts sharing common activity. Organization has been defined in different ways …
Read MoreInspection and Testing Inspection is an organized examination or formal evaluation exercise. In production, it involves the measurements, tests, measuring gauges and test equipments applied to certain characteristics in regard to a material or a product. The results are normally compared to the specified requirements and standards for determining whether the material or the product …
Read MoreX-Ray Fluorescence (XRF) Spectrometer X-ray fluorescence (XRF) is used to detect and measure the concentration of elements in substances. Fluorescence is the phenomena of absorbing incoming radiation and reradiating it as lower-energy radiation. X-rays are part of the electromagnetic spectrum with energies ranging from 0.1 keV to 100 keV (Fig 1a). X-rays are produced by …
Read MoreOrganizational Ethics and Values and their Importance Corporate governance refers to the system by which an organization is directed and controlled. One of the goals of corporate governance is to create a set of internal mechanisms to ensure sound managerial decisions are made, considering the rights and responsibilities of various stakeholders, together with the ethical …
Read MoreNozzle Clogging The disorder of casting process because of nozzle clogging is a long-standing issue ever since the continuous casting process has been introduced. Nozzle clogging is the build-up of solid or semi-solid material on a refractory surface which can become problematic during steel pouring, as it can affect the stream dynamics, reduce the pouring …
Read MoreSpark Optical Emission Spectrometer Chemical analysis and the identification of metals are used for a wide variety of purposes. These have become necessary to control the incoming goods or to ensure that the manufacturing process produces the product with the correct elemental composition. It is also used in failure investigation to determine if the correct …
