A Project Scheduling Problem consists in deciding “who does what” during the software project lifetime. This is a capital application in the practice of software engineering, since the total budget and human resources involved must be managed optimally to end in a successful project. In short, the main interest of a company is to reduce the time and the cost of the project, and these two goals ...

Plastics wastes from a municipal solid waste (MSW) plant have a high-energy content and are suitable for fuel generation. Thermal cracking is one of the possible ways to obtain petrochemical feedstock from polymer wastes. Municipal waste plastic of LDPE conversion to kerosene grade fuel experiments were carried out under atmospheric conditions at temperatures between 150 ̊C and 420 ̊C. Low densit...

Comprehensive two-dimensional gas chromatography (GC x GC) has been investigated for the characterization of high valuable petrochemical samples from dehydrogenation of n-paraffins, Fischer-Tropsch and oligomerization processes. GC x GC separations, performed using a dual-jets CO2 modulator, were optimized using a test mixture representative of the hydrocarbons found in petrochemicals. For comp...

Capacity regulation system by controlling suction valve is useful for large scale reciprocating compressor in petrochemical engineering field. The dynamic performance of adjustment device influences the stability and accurancy of this system. In this paper, a mathematical model of adjustment device coupled with the motion of suction valve is built, and the dynamic performances of valve plate ar...

Given hundreds of potential gas detector locations, a stochastic programming formulation is developed for determining the optimal placement of these sensors for detecting gas release events in petrochemical facilities. Using a rigorous dispersion model with actual geometry from the process facility, hundreds of different scenarios are simulated using FLACS with different leak locations, process...

Explosion occurs due to sudden release of energy. Common examples of explosion include chemical, atomic, heat, and pressure tank (due to ignition) explosions. Petroleum, gas, and petrochemical industries operations are threatened by natural risks and processes. Fires and explosions are the greatest process risks which cause financial damages. This study aims at designing a single-floor structur...

D evelopment of oil and gas fields is facing many risks, which are mainly due to uncertainties about the existence of commercial reserves, natural and economic environment, political conditions of host countries, legal and infrastructure issues and a market for petroleum products. In such an environment, investors are often engaged as contractors to develop and operate petroleum proj...

conclusions according to the findings, there has been a rise in the number of unsafe actions in machinery and maintenance service units compared to other maintenance units. as such, training courses based on the behavior-based safety principles at the beginning of employment, close monitoring of health safety environment (hse) officials on the implementation of regulations, and provision of app...

Due to the limitation of resources, the need to foster the developments and the lack of some competencies internally, companies are forced to cooperate with external agents, like other companies and universities, as suggested by the Open Innovation paradigm. Although there are lots of studies dealing with partner selection factors in alliances in the firm level, few studies are devoted to under...
