AbstractAbstract
[en] Two solutions are obtained for the optimal size of a biomass utilisation facility subject to an economy of scale in capital and non-fuel operating costs. The conventional assumption of constant-scaling parameter over all capabilities leads to a larger optimum than if the scaling factor is increased asymptotically towards 1 with increasing capacity to reflect technical and economic constraints or risks. Lack of appropriate scaling data for larger sizes makes the question of general optimization for biomass facilities uncertain and conclusions regarding development policie based on assumptions of constant cost scaling should be carefully tested.

AbstractAbstract
[en] Numerous innovations happened in the last few years in the LNG industry. So, the old plants even though still in service require large improvement. Renovation program for debottlnecking, extension and improve reliability can be an acceptable event to achieve plant modernization. The Algerian national company Sonatrach has performed a large renovation project of its LNG facilities to achieve a plant reliability improvement, over capacity and modernization program. During the construction phase some technical, safety, cost extension, guarantee problems which were not expected at the engineering phase have been identified. By treating all these aspects, Sonatrach accumulated a significant experience in a renovation concerns. This paper will report some important aspects of this experience and the results obtained in terms of safety, reliability, design, performance and technology improvement. (au)

AbstractAbstract
[en] A look at alternative sources of funds to finance ongoing natural gas processing operations is presented. Among the alternatives discussed was re-evaluation of the benefits of ownership of midstream processing assets, including the retention of such assets upon the acquisition of packages of petroleum and natural gas properties. This presentation describes what are considered typical problems that might arise when contemplating an off balance sheet financing of a gas processing facility, and the numerous issues that arise under the Construction, Ownership and Operating Agreement. The discussion includes the sales agreement, the construction of facilities, gas transportation and processing agreements, contract facility operating/management agreements, lender arrangements, and restructuring the construction, ownership and operating agreement

AbstractAbstract
[en] The current status of various tax issues regarding ownership, operation and financing of gas processing facilities in Canada was discussed. Frequently, energy companies are not taxed because of their large pools of un-depreciated capital cost and other resource related accounts. In addition, their time horizons for taxability are being extended in line with the expansion of their businesses. However, other investors are fully taxable, hence they wish to shelter their income through the use of tax efficient investment arrangements. This paper provides a detailed description of the tax treatment of gas processing facilities, tax implications of various structures between the producer and the investor such as lease, processing fee arrangements etc., and use of 'Canadian Renewable and Conservation Expense' (CRCE) for cogeneration projects within processing plants. All these need to be considered before completing a financing transaction involving a gas processing facility, since the manner in which the transaction is completed will determine the advantages and benefits from an income tax perspective. The accounting and legal aspects must be similarly scrutinized to ensure that the intended results for all parties are achieved. 8 figs

AbstractAbstract
[en] The negotiation of gas processing fees from the perspective of the natural gas producer are summarized. Some of the topics discussed are: evaluation of fee proposals, capital cost estimates, pipeline capital fees, compressor capital fees, plant capital fees, upper and lower limits on fees, (JP-90 and JP-95), negotiation options, operating costs, production allocation, and processing agreements. Several case studies involving one or more of these items were reviewed by way of illustration. The importance of documentation of all agreements, changes to agreements, commitments, etc., was stressed

AbstractAbstract
[en] In 1989, a decision was taken by the Shareholders of Malaysia LNG Sdn Bhd (MLNG) to expand their existing LNG manufacturing facility of some 8.0 million tonnes per annum, and to minimise the capital investment by maximizing the use of available off-plot facilities and utilities, together with the introduction of proven technological enhancements. Accordingly a new Company (MLNG Dua) was set up to own and manage this project and joint venture between existing shareholders. This paper describes the organisation, planning, and execution of the precommissioning, commissioning, start-up, and operation of the off-plot facilities, integrated utilities, and the first new process module, such that on-grade LNG rundown into MLNG's existing storage capacity was achieved within 26 days of the process module being signed off as Ready for Start-up (RFSU).

AbstractAbstract
[en] In recent years several authors have argued for the adoption of certain new types of risk perspectives which highlight uncertainties rather than probabilities in the way risk is understood and measured. The theoretical rationale for these new perspectives is well established, but the practical implications have not been so clearly demonstrated. There is a need to show how the new perspectives change the way risk is described and communicated in real-life situations and in its turn the effects on risk management and decision making. The present paper aims at contributing to this end by considering two cases, related to a national risk level, and a specific analysis concerning an LNG plant. The paper concludes that the new risk perspectives influence the current regime in many ways, in particular the manner in which the knowledge dimension is described and dealt with. Two methods for characterising the strength of knowledge are presented, one of them based on a new concept, the “assumption deviation risk”, reflecting risks related to the deviations from the conditions/states defined by the assumption made

AbstractAbstract
[en] A major objective of the present work is to provide means for representing a process plant as a socio-technical system, so as to allow hazard identification at a high level. The method includes technical, human and organisational aspects and is intended to be used for plant level hazard identification so as to identify critical areas and the need for further analysis using existing methods. The first part of the method is the preparation of a plant functional model where a set of plant functions link together hardware, software, operations, work organisation and other safety related aspects of the plant. The basic principle of the functional modelling is that any aspect of the plant can be represented by an object (in the sense that this term is used in computer science) based upon an Intent (or goal); associated with each Intent are Methods, by which the Intent is realized, and Constraints, which limit the Intent. The Methods and Constraints can themselves be treated as objects and decomposed into lower-level Intents (hence the procedure is known as functional decomposition) so giving rise to a hierarchical, object-oriented structure. The plant level hazard identification is carried out on the plant functional model using the Concept Hazard Analysis method. In this, the user will be supported by checklists and keywords and the analysis is structured by pre-defined worksheets. The preparation of the plant functional model and the performance of the hazard identification can be carried out manually or with computer support. (au) (4 tabs., 10 ills., 7 refs.)

AbstractAbstract
[en] PT. Badak's LNG sales commitment has been steadily increasing, therefore, there has been more emphasis to improve and maintain the LNG plant reliability. From plant operation historical records, Badak LNG plant experienced a high number of LNG process train trips and down time for 1977 through 1988. The highest annual number of LNG plant trips (50 times) occurred in 1983 and the longest LNG process train down time (1259 train-hours) occurred in 1988. Since 1989, PT. Badak has been able to reduce the number of LNG process train trips and down time significantly. In 1994 the number of LNG process train trips and was 18 times and the longest LNG process train down time was 377 train-hours. This plant reliability improvement was achieved by implementing plant reliability improvement programs beginning with the design of the new facilities and continuing with the maintenance and modification of the existing facilities. To improve reliability of the existing facilities, PT. Badak has been implementing comprehensive maintenance programs, to reduce the frequency and down time of the plant, such as Preventive and Predictive Maintenance as well as procurement material improvement since PT. Badak location is in a remote area. By implementing the comprehensive reliability maintenance, PT. Badak has been able to reduce the LNG process train trips to 18 and down time to 337 train hours in 1994 with the subsequent maintenance cost reduction. The average PT. Badak plant availability from 1985 to 1995 is 94.59%. New facilities were designed according to the established PT. Badak design philosophy, master plan and specification. Design of new facilities was modified to avoid certain problems from past experience. (au)
