The longwall mining method is one of the most applied methods in extracting low-inclined to high-inclined coal seams. Selection of the most suitable extraction equipment is very important in the economical, safety, and productivity aspects of mining operations. There are a lot of parameters affecting the selection of an extraction equipment in mechanized longwall mining in steeply inclined coal...

The Circuit Breaker (CB) is one of the most important equipment in power systems. CB must operate reliably to protect power systems as well as to perform tasks such as load disconnection, normal interruption, and fault current interruption. Therefore, the reliable operation of CB can affect the security and stability of power network. In this paper, effects of Condition Monitoring (CM) of CB on...

This research is concerned with developing repair and training strategies for stand-by equipment which maximise the time until the equipment is unable to respond when it is needed. Equipment can only be used if it is in an operable state and the users have had sufficient recent training on it. Thus it is necessary to decide when to maintain/repair the equipment and when to use the equipment for...

Rio de Janeiro, Brazil. In 2008, he was invited to lead the Dynamic Equipment area of COMPERJ, the biggest petrochemical complex of Brazil, still under construction. He joined Petrobras in 1989, and began working with rotating equipment maintenance. He was transferred to the process area dealing with rotating equipment optimization, operational proceeding improvements, and operator training, mo...

The design of facility layouts involves a decision process which, in general, due to its complexity, has to be decomposed into several sub-problems, namely: the selection of the most adequate manufacturing processes, the planning of equipment and labour requirements, the allocation of manufacturing operations to machines, the grouping of machines into sections (cells or departments), the select...

Reliability estimation plays a significant role in the performance assessment of mining equipment, and aids in designing efficient and effective preventive maintenance strategies. Continuous and random/irregular occurrence of failures in a system could be the main cause for performance drop of machinery. The accomplishment of a projected level of production is possible only by an efficient oper...

OCI Nitrogen seeks to gain knowledge of (leading) indicators regarding the process safety performance their ammonia production process. The current research determines most dangerous equipment by calculating effects resulting from a loss containment using DNV GL's Phast™ dispersion model. In this paper, flammable and toxic release main an plant have been calculated. Such encompassing approach, ...

hot-melt extrusion is one of the most widely applied processing technologies in the plastic, rubber and food industry. today this technology has found its place in the array of pharmaceutical manufacturing operations. melt extrusion process are currently applied in the pharmaceutical field for the manufacture of a variety of dosage forms and formulations such as granules, pellets, tablets, supp...

Just like any other process, vaccine manufacturing procedures are defined as a series of interrelated functions and activities using a variety of specified actions and equipment designed to produce a defined product. To assure the reproducibility and consistency of such processes, they must be carried out using validated equipment and under the established procedures that meet all the acceptanc...

Within the framework of the Trilateral Initiative, technical challenges have arisen due to the potential of the International Atomic Energy Agency (IAEA) monitoring fissile material with classified characteristics, as well as the IAEA using facilityor host country-supplied monitoring equipment. In monitoring material with classified characteristics, it is recognized that the host country needs ...
