As amply acknowledged, operational errors can be identified as one of the most common cause of plant equipment deterioration, consequently the operational control exerts a determining role in managing and slowing down the effects of aging and enhancing safety. Given the ongoing trend towards advanced sensors and real-Time performance...

The focus of the present paper is the development of a resilience framework suitable to be applied in assessing the safety of ship LNG (Liquefied Natural Gas) bunkering process. Ship propulsion considering LNG as a possible fuel (with dual fuel marine engines installed on board) has favored important discussions about the LNG supply chain and...

A survey addressing the uses of bismuth oxide in photocatalysis is presented. The richness of literature on such a specific topic proves the growing importance of this compound as a valid tool in pollution abatement and environmental decontamination. Many research groups have focused their activity on how to improve the photocatalytic...

Carbon nanoparticles (CNPs) gained a growing attention for a wide multiplicity of applications. CNPs offer the basic advantage of being well tolerated by living organisms and they are much more environmental friendly than many other inorganic NPs for analogous purposes. In this short review, several techniques are described and compared,...

In the food industry, water is frequently used both as a system utility and as a component that enters products and sub products. In other words, fresh water entering the process exits it either in the wastewaters or in the products. Consequently, the usual optimisation techniques for minimizing the overall water consumption are to be modified...

An important feature of tank pool fire is that the targets of interest for critical effects may include other plant units, such gas pipelines, storage sites, process sections, with heat transfer modes not limited to radiation. This paper, which takes inspiration from a recent work of the same authors, considers the physical model of a...

The purpose of this work is to outline a framework for assessing the resilience of a petrochemical storage plant, through the construction of a dynamic hierarchical Bayesian network. The BN approach allows keeping memory of the states, in order to manage the actual safety and reliability evidences during the petrol transfer operation from...

In the present era, the spread of cyber-physical systems in the framework of the so-called Industry 4.0, is leading towards a complete automation of industrial processes, which are increasingly decentralized, smart, and require fewer and fewer frontline personnel. The risk assessment process is certainly not excluded from the revolution, and in...

A green and sustainable process is proposed for the synthesis of metal nanoparticles (NPs) by means of a solid disaggregation in a liquid phase. A solid metal substrate, embedded in a solution containing suitable capping agents and surfactants, undergoes comminution carried out by a rotating shaft of hardness greater than the one typical of the...

The growing demand of nanomaterials is pushing towards the development of alternative strategies for the safe and sustainable production of nanoparticles. At the same time, to ensure high performances, a fine control over the product specifications is required. We focused on a bottom-up method combined with a mechanical disaggregation technique...

As widely reported in the scientific literature, audits, benchmarking, safety performance indicators and accident data help the management to understand the current safety performance status and to individuate strong and weak areas of the safety management system. Additionally, being process safety incidents relatively rare, as evidenced in the...

We observed exceptionally large pores (1–2 μm diameter) on aluminum electrochemically treated at relatively low voltage bias (50 V) under cathodic polarization. The pore spacing and size did not correlate with the proportionality law of nanoporous aluminum oxide, and appeared at least one order of magnitude higher. We did no inquire the...

The continuous changes in socio-political scenarios of the last decades led to an impressive increase in terrorist events related to the use of improvised explosive devices (IEDs). The energetic material contained in them, representing the essential part of the apparatus, is object of intense investigation owing to the need of optimizing many...

Identification of an oil spill is essential to evaluate the potential spread and float from the source to coastal terrains, and their continued monitoring is essential for managing the environmental protection actions to confine the pollution and avoid further damage. The SAR sensor is perceived as the most significant remote sensing apparatus...

As widely acknowledged, learning from accidents represents one of the main source of knowledge for future loss prevention. An effective investigation may help enhancing the process of continuous improvement of the safety management system. Recently, during a pipeline batching operation between two storage facilities of the same corporation, a...

Chromium shavings are toxic waste produced by the tanning industry and include both liquid and solid materials contaminated with chromium(III). Their treatment by pyro-gasification in a plasma torch allows to convert them into an inert solid residue; unfortunately, the high temperatures involved in the process (∼1500 °C) induce the...

Physicochemical methods such as adsorption on activated carbon, oxidation with either ozone or Fenton reagent, and chemical precipitation (coagulation), were assessed for the removal of polyethylene glycol (PEG) from wastewater. This contaminant is rarely investigated due to its low toxicity, although its presence limits the use of large water...

afety culture and awareness by workers are pivotal tools for the implementation of systematic procedures aiming to risk mitigation in the process industry. The evaluation of human factors on safety performance can reveal unsafe attitudes and failures in training, supervision and management, whose correction greatly contribute to the enhancement...

A critical survey concerning biocidal energetics is proposed according to a classification depending on their chemical structure. The need of optimizing the performances of such compounds is an important target for the inertization of biological weapons, requiring a synergy between the thermal effects of combustion/detonation with the biocidal...

The tanning industry is one of the oldest industries in the world and is known for the production of a wide variety of toxic waste (aqueous and solid) containing chromium salts and other heavy metals. Solid waste is produced during the conversion of putrescible collagen fibres into finished non-putrescible leather products. In this process, the...

The use of nature-like technologies, leading to acceleration of the processes of natural destruction of pollutants, is one of the promising directions for oil and petroleum product degradation in the environment. The joint use of oil-degrading bacteria and natural polymers with the properties of surfactants and humic acids (HAs) in bioorganic...

Nanoparticles of zerovalent Gallium have been produced by surface disaggregation carried out by means of mechanical abrasion in aqueous phase where capping agents have been dissolved. The particles have been characterized in diameter by dynamic light scattering. At a constant grinding force acting on metal surface, it has been observed that the...

A process concerning bismuth nanoparticle synthesis by an eco-fiendly reductant in mixed solvents is proposed. The method relies upon a redox reaction carried out at mild operative conditions using tin salts as electron donors. The reaction is performed in the presence of polyvinyl-pyrrolidone (PVP) and sodium dodecyl-sulphate (SDS) as capping...
