Economic advantages of dynamic analysis in the early stages of mining projects

Abstract The use of dynamic simulation is technically advantageous for the project as shown by various authors. However, is it economically advantageous in the early stages of the project (FEL1 and FEL2)? The methodology to economically evaluate the use of dynamic simulation considers the time and development cost compared with the time and cost spent to change the project in the next phase, considering changes that could be avoided with the use of dynamic simulation. Five process plant projects were evaluated, each one with an estimated CAPEX of US$ 300 million. The saved average is US$ 44,200.00 and US$ 182,400.00 for FEL 1 and FEL 2 respectively. The percentage cost savings for FEL2 (2.0%) and FEL3 (3.1%) are significant. The estimated delay avoided for FEL2 (3 weeks) and FEL3 (8 weeks) is directly related to the implementation delay, whose cost is expressively greater than the savings shown. The study concludes that the use of dynamic simulation is economically advantageous for the project.

기자재 라이브러리 구축을 위한 3D 형상, 사양 및 포트 정합 시스템의 개발

In process plant projects, plant 3D CAD systems are used for basic and detail designs. Plant 3D CAD systems typically adopt the specification-driven modelling approach in which designers choose a modeling template called catalog for a plant item from a predefined modeling library, instantiate the selected template, and then placing it in the 3D design space. Therefore, equipment and materials catalog library should be constructed in order to support plant design using a plant 3D CAD system. The catalog typically consists of 3D shape, specifications, and ports which are generated by different systems. Therefore, it is necessary to develop a system which integrates 3D shape, specifications, and ports to create input data for the catalog library. In order to address this issue, a data structure for the catalog was first defined. A system to create catalog data by integrating 3D shape, specifications, and ports was then designed. According to the design, a prototype system was implemented and experiments using test cases were performed to verify the feasibility of the prototype system.

Integration of Fire and Explosion Index in 3D Process Plant Design Software

AbstractProcess design management system is the essential computer‐aided design type of software used in design and 3D modeling of process plants. Actually, it is a management center of process plant projects which allows designers and engineers from various disciplines to concurrently create, control, and manage changes to the plant design and other related engineering data. Some methods for achieving the inherently safer designs guide the location of process equipment and utilities. Therefore, there is room for close interactions between 3D modeling and methods to assess the inherent safety. The feasibility of integration of the Fire and Explosion Index into 3D modeling of industrial chemical processes is evaluated and supported by a case study. The importance of the presented concept as key part of such management philosophies like the lean design and the building information modeling is highlighted.

Geographic Information System for Coordination of Fast‐Track Projects

To meet the increasing demands to deliver projects within a short period of time, many projects are being executed on a fast‐track basis. On fast‐track projects, the construction begins when the design is between 35% and 65% complete. This poses numerous challenges. One of the key challenges is to ensure that the flow of information and deliverables between the engineering, procurement, and construction is synchronized. This work initially studied the information flow on process plant projects, the disruptions to information flow, and the problems faced due to the disruptions. It was identified that an information system that has the capability to (1) capture the relationships between different deliverables, (2) record the status of deliverables, and (3) process queries from any of the teams regarding status and impact of disruptions will support the decision‐making required for rapid development of pragmatic plans. Further, as the information requirements require the representation and querying of both spatial and nonspatial data, the design and implementation of the system using the concepts and features of a geographic information system was explored. The paper discusses the design of the geographic information system and its implementation within the AutoCAD Map environment. The use of the system to retrieve information required for project coordination is illustrated through sample queries.

Planning and innovative design — the key to successful process plant projects

Ever since the Biwater Group of Companies acquired Chemical and Thermal Engineering Ltd in 1982, and renamed the company Biwater Process Plant, the industry has continued to refer to both the old and new name.

Early life availability of chemical process plant

Availability is increasingly being recognised as a factor having an important effect on the economics of process plant operation. However, previous analyses of the availability of process plant have generally included the assumption that failures and repairs of plant items follow an exponential distribution, largely due to the intractable nature of the analytical equations if the failure and repair rates are non-exponentially distributed. This paper outlines a model, and its subsequent solution by numerical methods, which enables the early life transient availability to be obtained for systems whose components exhibit non-exponential failure and repair behaviour. The situation most closely studied is where the failure rate is initially higher, due to such reasons as incorrect design or installation, or faulty components. Poor initial availability and a significant delay in obtaining full production can seriously affect the economic returns gained from the high capital investment required in most process plant projects.
