The main objective of optimizing any chemical process is to find the best operation conditions that can maximize the production of the most valuable products and minimize operating costs with respecting the operational and environmental constraints. Uncertainty or variations in some parameters such as demand and supply of each processing unit or product prices can seriously affect the optimizat...

Background: Primary hypothyroidism (PH) is the most common thyroid pathology. Purpose: to evaluate the impact of public disclosure of an unexpected number of PH cases on the frequency of patients seeking medical evaluation for endocrinological diseases. Methods: data on 6306 subjects (3356 living in the surroundings of a petrochemical complex and 2950 in a control region) were collected over a ...

Under the Rio Declaration and Agenda 21 from the United Nations Conference on Environment and Development in 1992 as well as other international agreements, Thailand is currently in the process of adopting the Pollutant Release and Transfer Register (PRTR) through a pilot project in Rayong province with assistance from the Japan International Cooperation Agency (JICA). This research aimed to st...

A mathematical model is developed and tested with plant data for the ammonia cold shot converter of Razi Petrochemical Complex. The model is based on a material and energy balance in a differential element of beds and is subjected to the assumptions of uniform distribution of temperature and composition through a general cross section and negligible mass and heat transfer in axial direction. Th...

Analysis of inventory systems involving market-oriented pricing decisions has recently become an interesting topic in the field of inventory control. Price and marketing expenditure are considered as important elements when selling goods and enhancing revenues by manufacturers. The importance of accounting for uncertainty in such environments spurs an interest to develop appropriate decision ma...

The paper describes an approach to predicting gas explosion loads and response which has been developed for offshore installations and which only recently has been adapted to onshore petrochemical facilities. The paper consists of three parts: Part 1: An overview of vapour cloud explosion hazards in petrochemical onshore facilities and a discussion of modeling approaches. Part 2: A probabilisti...
