2017 World Chemical Engineering Congress

ioMosaic Is Presenting at Conference

When: October 1-5, 2017
Where: The Gran Via Convention Centre, Barcelona, Spain

An increasing world population, in a world of finite natural resources, requires ever more innovative chemical engineering to solve problems and produce new, better products. Many economic and ecological challenges of the 21st century can only be solved on a global scale. Chemical engineering and related sciences will play a key role in meeting future societal needs.

Session: Bridging the Safety Gap: The Key Role of a Sound Process Safety Culture in Minimizing Audit Findings
Presentation #OC-55911
October 3rd, 8:30 am – 10:00 am

Process safety focuses on prevention and mitigation of fires, explosions, hazardous material releases, and other potentially large incidents associated with the chemistry and physics of the manufacturing process. Continuous improvements in process safety requires more focus on management systems and process safety culture. However, establishing a sound process safety culture and ensuring an effective implementation of management systems is what companies find difficult. Therefore, conducting proper process safety audits and addressing the findings are key to identify potential weaknesses and monitor process safety culture.

The presentation illustrates a case study that compiles and analyze management system audit findings and related data from a sample of sixteen (16) process facilities. The study identifies the most frequently cited elements and compares them with the results obtained by Occupational Safety and Health Administration (OSHA) refinery and chemical National Emphasis Program (NEP) inspections. Additionally, process safety culture benefits towards minimizing or avoiding audit findings are provided.

Ms. Prats is a Partner at ioMosaic where she is responsible for leading and supporting the firm’s Process Safety Management consulting group. As the group leader, she has helped many companies with PSM implementation for PSM and non-PSM covered processes. Ms. Prats holds a Chemical Engineering degree from the Institut Químic de Sarriá in Barcelona, Spain and an Executive Masters degree in Operations and Supply Chain Management from the Escuela de Alta Dirección y Administración in Spain.

Session: Characterization of BLEVE Phenomena in Equipment Exposed to External Fire - Combining Dynamic Thermal Stress Analysis & Vessel Wall Segmentation Approach
Presentation #54776
October 3rd

A safety study was performed to verify the adequacy of an installed Pressure Relief Valve (PRV) protecting a vessel exposed to external fire. An accurate method for predicting the Time To Failure (TTF) is proposed by combining Dynamic Thermal Stress Analysis (DTSA) with a vessel wall segmentation approach. The safety study analyzed the system with an undersized PRV first, then with an adequately-sized PRV, and also with an adequately-sized PRV when the vessel is fitted with fire-proof insulation. Conditions obtained at the estimated TTF for all three cases were then analyzed with a vessel burst model to predict and compare the different impact distances as a result of a Boiling Liquid Expanding Vapor Explosion (BLEVE). The study highlights the importance of accurately predicting the available energy remaining in the equipment exposed to fire at TTF for reliable consequence modeling, effective emergency response, and decision-making.

Dr. Dunjó's engineering and process safety expertise lies within the quantitative evaluation of risk facing chemical, petroleum and pharmaceutical process facilities, and in developing hazard analyses using various methodologies for a wide range of applications, such as fire risk assessments and risk-based facility siting studies. Dr. Dunjó holds a University Degree in Chemical Engineering from the Chemical Institute of Sarrià in Barcelona, Spain, a Masters Degree in Occupational Risk Prevention from the Autonomous University of Madrid in Madrid, Spain and a Ph.D. in Chemical Engineering from the Polytechnic University of Catalonia in Barcelona, Spain.

Session: A Risk-Based Approach to Facility Siting of Process Plant Permanent and Portable Buildings which may be exposed to Explosions - Combining Exceedance Curves, Structural Response, and Human Vulnerability Criteria
Presentation #OC-55276
October 3rd

The Chemical Industries Association (CIA) and the Center for Chemical Process Safety (CCPS) provide occupant vulnerability criteria to overpressures by defining generic building classes. Alternatively, the US Department of Defense (DoD) provides criteria for occupant vulnerability based on structural response by using dedicated pressure-impulse diagrams which consider the complete blast loading phenomena. This study proposes a risk-based structural analysis assessment capable of predicting the building damage level and the associated probability of fatality, major and minor injury of occupants. The procedure complies with facility siting criteria established in recommended practices such as API 752 and API 753. It also combines two engineering tools: (1) construction of Overpressure Exceedance Curves (OECs) used for identifying which overpressure level (and associated impulse) impacts the target structure / building for a given frequency threshold, and (2) DoD criteria for predicting occupancy vulnerability as a function of building damage and glass breakage levels. A case study illustrates the procedure which includes the identification of impacting explosions on a building, the blast loading phenomena to the building’s sides and roof, the prediction of the overall building damage level and, finally, the construction of dedicated FN-curves.

Mr. Amoros is experienced with quantitatively evaluating the risk of chemical, petroleum, and pharmaceutical process facilities; i.e., expertise on hazard identification, frequency estimation consequence modeling, decision-making process for risk reduction measures, and quantitative risks assessments - including fire risk assessments and risk-based facility siting studies. Additionally, Mr. Amoros’ expertise includes pressure relief and flare system design analysis for large chemical and petrochemical companies in the United States. Mr. Amoros holds a Bachelors Degree in Chemical Engineering and a Masters Degree in Bioprocess and Chemical Engineering from Ramon Llull University in Barcelona, Spain.

Session: A Review of the 2012 Reynosa Gas Plant Explosion
Presentation #OC-35181
October 3rd

In September 2012, a major fire and explosion ripped through a gas plant in Reynosa, Mexico resulting in 31 fatalities and many injuries. The incident was caught on CCTV and has been viewed millions of times on social media. The video clip is particularly useful to process safety practitioners as it demonstrates the various hazardous outcomes that can result from one loss of containment event. In the case of this incident, it is possible to see the initial pressure wave, followed by turbulent momentum jet dispersion, then a flash fire and jet fire. This presentation reviews the potential causes leading to the incident, as well as summarizing the lessons learned. Additionally, it emphasizes the need for a complete and thorough Process Safety Management program.

Mr. Prophet is a Senior Partner with ioMosaic Corporation, and manager of our Houston office. He has eighteen years’ experience in the field of process safety, and has worked in a variety of process safety roles including consulting, technical support, technical sales, and training. His current responsibilities for ioMosaic Corporation, include managing Pressure Relief and Flare System design studies, and conducting Quantitative Risk Analysis studies. Mr. Prophet has a Bachelor of Engineering in Chemical Engineering, and a Postgraduate Diploma in Energy Systems & the Environment, both from the University of Strathclyde in the United Kingdom.
