Fluid catalytic cracking (FCC) is a method of vegetable oils into simpler fractions and green fuel oils. One component the FCC system furnace. The furnace where combustion process occurs provides high heat transfer throughout system, especially for heating reactor. reactor temperature catalyst temperature. depends on feed oil used in process, such as crude palm at 450‒550 °C or bio-oil 300 °C. ...

It has been known that a high-emissivity furnace provides an energy-efficient alternative to a conventional furnace [1,2]. To improve the efficiency of a furnace, ceramic coatings with high emissivity are often applied to the interior of the furnace. The purpose of this paper is to show the amount of electrical energy-saving achieved by emissive carbon coating for a tubular vacuum-furnace. Alum...

This project examines the nature of password cracking and modern applications. Several applications for different platforms are studied. Different methods of cracking are explained, including dictionary attack, brute force, and rainbow tables. Password cracking across different mediums is examined. Hashing and how it affects password cracking is discussed. An implementation of two hash-based pa...

Briquetting is a process in which fine materials unsuitable for use as such are agglomerated to achieve larger particle size. Auger pressing novel briquetting method efficiently improve the recycling of by-products from iron and steelmaking. The high-temperature properties auger briquettes mainly consisting blast furnace sludge mill scale were evaluated. aim was determine suitability (BF) ironm...

current article describes application of zeolites in fluid catalytic cracking (fcc). the use of several zeolitic additives for the production light olefins and reduction of pollutants is described. application of zeolites as fluid catalytic cracking (fcc) catalysts and additives due to the presence of active acid sites in the zeolite framework  increase the formation of desired cracking product...

In this work, the effects of scale on thermal behavior of the slab in a walking-beam type reheating furnace is studied by considering scale formation and growth in a furnace environment. Also, mathematical heat transfer model to predict the thermal radiation in a complex shaped reheating furnace with slab and skid buttons is developed with combined nongray WSGGM and blocked-off solution procedu...

In this study, the early age thermal properties of a concrete mix containing ground granulated blast furnace slag (GGBFS) were investigated and incorporated in finite-element model. A two-term exponential degree hydration function was proposed to better capture behavior. An FEM program (ABAQUS) used predict temperature time-history three 1.2-m (4-ft) cubes cast with design 50% replacement cemen...

Abstract Standard methods for fire resistance testing require large‐scale assemblies and are typically conducted on specialized furnaces at considerable cost. This research focused developing a scaling methodology reduced‐scale test that reduces the size of article while maintaining same thermal structural response exhibited in test. The developed incorporates uniform geometric scaling, Fourier...

steel industry is one of the most consumption of energy in the world, which is related to melting furnace which result environmental pollution. we calculate the energy consumption and capital cost of dust collectors of venturi scrubber (vs) and electrostatic precipitator (esp) which are connected to melting furnace in respect to industrial ecology for selection of appropriate dust collection sy...
