  • Practice Makes Perfect (Paper, 2017)

    Manel Serra (Inprocess), Dieter Krenz (Linde), Theron Strange (Simplot Phosphates)

    Abstract

    Published in World Fertilizer in September-October 2017

    Process simulation is a technology used in many areas and project phases. Its usage ranges from the design stage of a plant (initial concept and front end engineering) to assistance in daily plant operations, including planning, optimisation and monitoring. To a certain extent, the simulation lifecycle is similar to the lifecycle of a process plant, bringing support and value to multiple stages in the lifetime of a process plant.

    Using Simplot Phosphates’ ammonia process plant in Rock Springs, Wyoming, USA, where dynamic process simulation has been used, as an example, this article focuses on the implementation and benefits of an operator training system (OTS) for the plant. It will explain this specific use of the OTS, as well as outline some experiences and results from the point of view of the three parties involved in the project: the licensor and engineering company in charge of the construction, Linde; the plant owner and operator, Simplot Phosphates; and the simulation services provider in charge of developing and deploying the OTS, Inprocess Technology and Consulting Group, S.L.

  • Lifecycle Aspen HYSYS Modeling for FPSO, from Engineering Studies to OTS (Congress Contribution, 2017)

    Kari Berte (Yinson), Leonardo Carpio, Sergio Juan, JoseMaria Nougues, Jesus Gil and Josep-Anton Feliu (Inprocess)

    Abstract

    Contribution to the Oil & Gas Training and Simulation forum held in June 2017 in Aberdeen (Scotland), UK

    This case study presentation shows a Dynamic Simulation Study (DSS) carried out for the Floating Production Storage and Offloading (FPSO) designed and operated by Yinson Production for the Eni’s OCTP development project in Ghana. The Aspen HYSYS Dynamics model was extensively used to run about 15 transient conditions (Start-up, Emergency Shutdown, Blocked inlet/outlet, load sharing, ramp-up, etc.) to verify the sizing, process layout, control layout, operating procedures, etc. During a second project stage, the detailed model was re-used to create a Lifecycle Direct-Connect Operator Training Simulator (OTS) by connecting it with the Integrated Control and Safety System (ICSS).

    Josep-Anton Feliu

    Abstract

    Published in Spanish in Industria Química in July-August 2015

    Safety and productivity in processing plants highly depend on the accurate performance of the control and safety systems, normally centralized in control rooms, through the distributed control systems and safety instrumented systems (DCS, SIS). In order to ensure the plant production, it is key to have staff perfectly trained in the operation of such automated systems

  • Simulating Superior Performance (Paper, 2015)

    Josep-Anton Feliu, José-María Ferrer, José-María Nougués

    Abstract

    Published in Hydrocarbon Engineering in March 2015

    An Operator Training System (OTS) is one of the best methods to train staff in operations before a producing plant starts up. Carrying out this training before plant commissioning ensures a fast learning curve of the new process and control and instrumentation systems. Moreover, the operators can be exposed to emergency situations or process upsets that are not part of the daily operation. This will facilitate the operator response to normal and abnormal process conditions

  • Imitate to Understand (Paper, 2012)

    Jose Maria Nougues, Michael Brodkorb and Josep A. Feliu

    Abstract

    Published in Hydrocarbon Engineering in May 2012

    Over the past 10 years the use of dynamic process simulation has been established as a reliable and effective tool to analyse transient behaviour of process systems.

    Centrifugal compressor systems show performance characteristics that mainly depend on the operating point imposed on them by the process units and the connection piping around the compressor.

    Large compression systems often have several compressors operating in parallel, with some of them in standby. Therefore, even in normal operation there are frquent start up and shut down operations while switching between compressors: to accommodate throughput changes, for example. The transient analysis of these operations is critical to evaluate the dynamic behaviour of the compressor system and the associated control and safety systems.

  • Dynamics Break the Bottleneck (Paper, 2011)

    Prabhat Panigrahy, Jens Balmer, Miquel A. Alos, Michael Brodkorb and Brian Marshall

    Abstract

    Published in Hydrocarbon Engineering in September 2011

    Flare and relief systems commonly found in processing plants in the oil, gas and petrochemical industries are constantly under examination.

    New constructions, extension of existing plants or changes in safety regulations all require detailed analysis of several aspects of the flare and relief system. In many cases, steady state analysis will suffice; but more often than not, complex or marginal problems require dynamic analysis to resolve an apparently bottlenecked flare system.
    This approach has recently been successfully applied to analyse and improve the blow down strategy for an existing gas utilisation plant (GUP) owned and operated by Wintershall in Libya

  • Are there alternatives to an expensive overhaul of a bottlenecked flare system? (Paper, 2010)

    Detlef Gruber, Dietmar-Uwe Leipnitz, Miquel Angel Alos, Jose Maria Nougues and Michael Brodkorb

    Abstract

    Published in Petroleum Technology Quarterly in Q1 2010

    There are different situations for which it is necessary to re-evaluate the capacity of a site\'s existing flare system. In general, this is necessary following a potential increase in flare load, e.g. when:
    - Relief Valves that currently blow to air and that need to be connected to the flare header,
    - Changes in regulation that redefine the scenarios for which the flare system has to be designed,
    - New plants that are connected to the existing flare header, or
    - Throughput increase / revamps of existing plants that might increase the flare load through higher hold-up or higher heat load.

    In this article, the authors give an overview of the advantages of the approach of using dynamic simulation to calculate flare loads following API 521, give guidance on when and where to apply it, and describe a case study of a recent study at BP’s Lingen refinery in Germany.

  • Alivio de Presión en Columnas de Destilacion de Crudo (Paper, 2008)

    Abstract

    Paper in Spanish published in Ingeniería Química in August 2008

    The estimation of relief loads from crude distillation units (CDUs) is quite complex due to the type of units, where composition is non constant all along the column and time. In this paper, the conventional way of calculating relief loads in steady state is compared with the results obtained appliying dynamic simulation to estimate such relieves in an atmospheric crude column

  • Utilizing Rigorous Simulation in Advanced Process Control Projects (Congress Paper, 2007)

    JoseMaria Ferrer

    Abstract

    Presented at: Seminar for Advanced Industrial Control Applications (SAICA) in November 2007

    Rigorous Simulation helps engineers to understand and identify process dynamics and interactions in a risk-free environment; in addition, it also allows the evaluation and tuning of advanced controllers before they are commissioned. A number of recent APC projects have benefited from this combined methodology, resulting in a better controller design, more accurate inferentials, less plant tests, more confidence with the controller models and an overall reduced risk. Suitability of the methodology for certain units and simulation myths and barriers are reviewed.

    ITOP is a new approach for training operators and young engineers in subjects like Process Engineering and Unit Operations. This approach combines process simulation based exercises with classroom training and motivates the attendees to experience complex theory through hands-on exercises.

    • Through ITOP the operators gain better process understanding, leading to increased plant reliability and improvement in overall operator performance, as well as improved ability to operate the plants in a safe way.
    • ITOP can be adapted to be aligned to support the company’s existing training strategy.
    • ITOP proves to the authorities the investment in operators knowledge to operate safely
