Plant startup organization

Fulks, B.D., Plamiing and Organizing for Less Troublesome Plant Startups, Chem Eng., 89,18,96,1982. 

Plant Startup (Chapter 18) provides guidelines for the activities, organization, and split of responsibilities of startup teams in order to insure prompt and safe startups. 

Cansolv A "flue-gas desulfurization process based on the selective absorption of sulfur dioxide in certain amine-based organic solvents. Developed by Union Carbide Corporation the first plant was planned for startup at Newburgh, IN, in 1994. See HS. 

At the initiation of the project in late June 1980, Bureau of Mines personnel were present to consult, assist, and advise. The Asarco Corpus Christi Plant Engineering Department organized and supervised the project at startup and assumed complete control after the departure of the Bureau of Mines personnel. The Bureau of Mines and The Sulphur Institute maintained periodic contact by telephone and visits throughout the work. 

On many major projects, startup is put on the back burner and not given the proper amount of planning and resources that are necessary to have a quick, successful demonstration of the operability. Although a well-planned startup will not overcome deficiencies in design and construction, a poorly organized one will seriously mar the completion of a well-designed and well-constructed plant. It is the responsibility of the Venture Manager to avoid this predicament. 

The organization of Fig. 7.56 shows that solids recycle techniques can be applied in modular fashion. They can be valuable in plant improvement and debottlenecking projects. Solids recycle is also useful as a temporary measure in startup of a clarifier. It helps the solids concentration in the compression zone to build up more quickly. 

To fulfil the chemistry requirements, the primary coolant has to be treated by the addition of chemicals. The concentrations of the additives needed have been given in specifications elaborated by specialists in detailed discussions and which are continuously re-evaluated based on the current state of knowledge. Table 1.4. shows an overview of the primary coolant specifications established by various vendors and institutions for plant normal operation periods (Mathur and Narasim-han, 1992). From these data, it can be seen that there is a worldwide consensus on the use of LiOH or KOH as a pH control reagent. Different vendors or organizations may recommend minor changes in some of these specifications as, for example, KWU not specifying fluoride, but fundamentally the plant specifications are virtually identical. During startup and shutdown phases, deviations from these specified data are allowed for a limited period of time.
