This article is a report of the attempts which were made to model an industrial premix gas burner which was operating in one of the furnaces of the Catalytic Reforming Unit (CRU) of Abadan refinery. The main objective of the modeling was to investigate on the effect of the structural geometry of the burner on its mode of operation, i. e. complete combustion of the gas, maximum generation of hea...

PURPOSE Petroleum refinery workers are exposed to the carcinogens benzene and 1,3-butadiene. Declining exposures have been reported internationally but information on current exposure in the Swedish refinery industry is limited. The aim was to examine refinery workers' personal exposure to benzene and 1,3-butadiene and increase awareness of exposure conditions by collaboration with involved ref...

Background Biofuels from hydrothermal liquefaction (HTL) of abundantly available forest residues in British Columbia (BC) can potentially make great contributions to reduce the greenhouse gas (GHG) emissions from the transportation sector. A life-cycle assessment was conducted to quantify the GHG emissions of a hypothetic 100 million liters per year HTL biofuel system in the Coast Region of BC....

Background: Gas refining is a process in which workers are exposed to different chemicals. This study aimed to assess the health risks caused by exposure to these substances in order to determine hazardous jobs and to present controlling methods. Materials and Methods: This cross-sectional study was performed on the workers at gas refinery in 2015. The sample included all the staff in operat...

This paper presents an integrated refinery scheduling model and its applications for a refinery located in Jiujiang, Jiangxi, P.R.China. The model integrates a crude oil unloading and storage area, a refining area, a blending area and a product storage area of the refinery. The scheduling model can be applied for optimizing the operation, configuration and production schedule of the refinery. T...

In particular, a straw-based Ablative Fast Pyrolysis (AFP) oil was upgraded via hydrotreatment (HDT) in order to be used as blending component with fossil-based intermediates. The raw pyrolysis is characterized by H/C = 0.14, O/C 0.58 and C 57.73 wt%, while the HDT has 0.016 85.85 wt%. Based on density, viscosity composition, association typical refinery, possible petroleum refinery entry point...

A model predictive control (MPC) strategy is developed to determine the optimal solution of the short-term refinery production planning problem. The main objective of the proposed algorithm is to maximize the total profit and to minimize the costs regarding the refinery process over a planning horizon. The refinery planning problem is solved in discrete time over a pre-determined prediction hor...
