Plant constructor

The American Institute of Chemical Engineers (AlChE) has helped chemical plants, petrochemical plants, and refineries address the issues of process safety and loss control for over 30 years. Through its ties with process designers, plant constructors, facility operators, safety professionals, and academia, the AlChE has enhanced communication and fostered improvement in the high safety standards of the industry. AlChE s publications and symposia have become an information resource for the chemical engineering profession on the causes of incidents and means of prevention. 

The effort involved is therefore disproportionate to the benefits achieved [11] and for the plant constructors is anyway outside the time horizon available to them when designing the crystallizers. 

For the plant constructors, the benefit of the population balance is mainly derived from the transparency of the interplay of the kinetic variables of nucleation rate and crystal growth rate, the mean retention time, the fines dissolving, and the classification of product crystals during withdrawal with respect to the resulting mean particle size of the crystallization process. Here, reference is made to the publications, such as that of Toyokura and Sakai [12]. 

How do plant constructors solve this task With the aid of the Wassermann Philosophy and the data provided by the supply chain, their product and comp o-nent development is both fast, on time and cost efficient. 

The SCM supports plant constructors and special-machine manufacturers in the fast and complete technical winding up of orders. The supply chain is an indispensable tool also for sales in customer negotiations. 

The goal of plant design is the realization of process plants within the framework of projects. Il.lj. Here, as a rule, two parties have to be distinguished first the plant operator who wants to procure and operate a process plant, and secondly the plant constructor who, according to the agreed scope of delivery and service, takes... 

The interface between project planning and project execution is the conclusion of the contract. This means the signing of the contract worked out by the plant operator and the plant constructor stipulating aU commercial and technical project... 

At this point it has to be mentioned that the operator may also be a public utility, such as the local authorities as operators of sewage works. As a rule, public utilities employ only little or no staff with plant-engineering qualifications. Therefore they are forced to outsource even those activities usually carried out by the operator. Often engineering companies that have to be independent from the future plant constructor are entrusted with this task. 

Availability or operating reliability is the actual operating time of a plant in relation to overall time. Usually it is stated as a percentage and relates to 8760 hours/ year, which correspond more or less to a year-round 24-hour-operation. Here, scheduled plant downtimes, e.g. for inspections, have to be taken into account Therefore, an availabiUty of 98% means that the plant may have a total downtime of 175 hours, i.e. 7.3 days. It is logical that the operator is interested in as much plant availability as possible. S/he will commit the plant constructor to adhere to availability. As a rule, penalties are provided in the case of non-compUance. Therefore, high demands on availability lead to increasing procurement and maintenance costs. In this comiection, redundancies and multi-line plants also have to be taken into consideration.

An exergy analysis of the conceptual design of the synclude mode H-Coal process for bituminous coal of Illinois No.6 has been carried out based on the data reported by the Fluor Engineers and Constructors, Inc.,(31). The plant is designed to convert 14,448 tons (short ton) of coal per day. 

Fluor Engineers and Constructors Inc., under contract with EPRI has completed a rather detailed study (8 ) of the cost of producing power via Texaco gasifiers and advanced design gas turbines and steam turbines. They conclude investment costs (mid-1976 dollars) to be 815 million for a plant gasifying 9600 T/D of moisture-free Illinois coal and producing 1150 megawatts of net power. 

Thereby, industry has three different appearances (a) The users of chemical process technology and of corresponding tools in the chemical companies, (b) the constructors and builders of chemical plants and, finally, (c) tool builders supporting the process of developing chemical plants. In Chap. 7 we explain our efforts to transfer results of the IMPROVE project to the industry of these three forms. 

The master plan is finalized during detail engineering. The protocols prepared (IQ s, OQ s and PQ s) and the validation files started during construction. The IQ s (Installation Qualifications) are performable as construction is completing and can be completed by the constructor under supervision. The OQ s (Operational Qualifications) can be performed during the earlier parts of start-up as verification of mechanical completion. The PQ s (Process Qualifications) are performed as start-up completes and continue through the operating life of the plant. For maximum schedule... 

The dual-temperature principle for providing reflux for the ammonia-hydrogen deuterium exchange process was proposed by the British firm Constructors John Brown [C12], has been tested in pilot-plant experiments conducted by Friedrich Uhde Gmbh at the plant of Farbwerke Hoechst in Germany [W2], and is to be used in a commercial plant at Talcher, India (item 19, Table 132), being constructed by Uhde. 

Estimates from a major Japanese nuclear reactor supplier and constructor (Callaway Nuclear Power Plant, 1989, pri. comm.) have indicated that the construction costs of the plants completed in Japan at the turn of the century (2000-2001) were in the range of 2200/ kW (EPC). Inflation to the present would add about 50% to these numbers, and bring these values to 3300/kW for EPC costs.

The site construction of APIOOO plants will be by a constructor. Safety will be a major discriminator in the choice and appointment of the constmctor. The constmctor will be required to develop a health, safety and environment programme to protect the project and site employees and... 

The constructor will be required to provide a site safety manual which will address, for example, fire protection, accident reporting and analysis, work planning and training of construction personnel. The manual will also include what constitutes an environmental impact statement for the plant construction. Safety audits and inspections will be undertaken during construction. The emphasis will be on a leading indicator approach to the management of safety. The selected constmctor will comply with the CDM regulations (Reference 9.9). 

The requirements of the CDM regulations (Reference 9.9) during commissioning will be met, including the appropriate handover of the plant from the constructor to the operator.
