Capital cost projects begin when a need is defined that cannot be satisfied in existing facilities. Thus begins the life cycle of a capital project (Fig. 1). Once started, the project will progress through all of the following phases or be canceled. It all starts with the recognition of a need that will require capital plant. In the conceptual phase of the project, multiple approaches will be evaluated and one or more plans will be evaluated for meeting these needs

The purpose ofthis chapter is to review various forms of solids dryers and auxiliary components. It is intended to be a practical guide to dryer selection (as opposed to the theory of drying, which is addressed in various technical manuals referenced in the bibliography). From a microscopic

The drying operation is often the final step of a manufacturing process. Indirect drying will be discussed in this section; it is the process of removing liquid by conductive heat transfer. Sometimes drymg is apart ofthe manufacturing process itself, as in the case of seasoning oftimber or in paper making, but generally, the reasons for carrying out a drying operation are:

“One should beware of mathematicians and all who make empty prophecies. The danger already exists that the mathematicians have made a covenant with the devil to darken the spirit and confine man in the bonds of Hell” St Augustine, Bishop of Hippo, circa 400 A.D “To move things is all that Mankind can do…For such the

Common, everyday water is a major consideration in a pharmaceu￾tical plant. The final product or any of its intermediate materials can only be as contaminant-free as the water available at that stage. Water may be an ingredient or used principally to wash and rinse product contact components and equipment. Water is also used to humidiethe air, to generate clean steam for sterilization, to cool or heat, as a solvent, for drinking and sanitary uses, etc. To better control this critical media

本课程是生物工程的专业必修课。通过课程学习,使学生了解、掌握有机酸发酵的基本理论及生产工艺,及行业的发展趋势和最新进展

Crystallization is one of the oldest methods known for recovering pure solids from a solution. The Chinese, for example, were using crystallization to recover common salt from water some 5000 years ago. The perfection and beauty of the crystal which fascinated the early tribes now leads to a product of high purity and attractive appearance
