introductionorganizations try to have a safe and healthy work environment without any pollution and damages. healthsafety environment (hse) system is a tool for improving health, safety, and environmental conditions in allindustrial and non-industrial development programs. the system uses all human and financial resources toprovide people with a safe environment without any risk (farshad et al....

A kinetic model of a fixed bed tubular reactor incorporating catalyst deactivation was developed for the ISOMAX unit of Arak refinery. The kinetic parameters for the hydrocracking reactions over the commercial catalyst were determined using initial activity plant data i.e. when the catalyst is fresh. Catalyst deactivation was then taken into account by means of deactivation function based on pl...

Hydrocracking has great importance in present day refining due to strict environmental and norms of quality of fuel. In recent years the demand for middle distillate and gasoline has increased tremendously while that of heavy gas has decreased. In the present work we have modeled and then applied five lump scheme to hydrocracker reactor. The first order kinetics was assumed for the conversion i...

This paper evaluates the influence of crude oil (vacuum residue) properties, processing fluid catalytic cracking slurry oil, and recycle hydrocracked vacuum residue diluted with heavy cycle operating conditions H-Oil hydrocracking on quality liquid products. 36 cases operation a commercial H-Oil® ebullated bed hydrocracker were studied at different feed composition, conditions. Intercriteria an...

Where are we in the story of British democracy? Was 2016 EU Referendum a rehearsal for new political system direct democracy that ultimately benefits far right? Or will Internet replace conventional machinery government with radical form network power where people discursively experiment realities through aesthetic modes social relations? This article proffers term ‘networked participation’ to ...

Reduced Hessian Successive Quadratic Programming (SQP) is well suited for the solution of large-scale process optimization problems with many variables and constraints but few degrees of freedom. The reduced space method involves four major steps: an initial preprocessing phase followed by an iterative procedure which requires the solution oj a set of nonlinear equations, a QP subproblem and a ...

The biofuel mix in transport in the UK must be increased from currently exploited 3.33% to the EU target mix of 10% by 2020. Under the face of this huge challenge, the most viable way forward is to process infrastructure-compatible intermediate, such as bio-oil from fast pyrolysis of lignocellulosic biomass, into biofuels. New facilities may integrate multiple distributed pyrolysis units produc...
