Evaporators are often used to concentrate a solution. An example is the climbing/falling film plate evaporator, which is used to make condensed milk.. Similarly, reduction (cooking) is a process of evaporating liquids from a solution to produce a "reduced" food product, such as wine reduction.
The systems, equipment, items, processes, modes, and sequences of operations to be tested by the CxP (contractors or others) should be detailed and identified in the design engineer's construction documents (drawings and specifications), the construction request for proposal (RFP), the contractors' bid submission, and the commissioning ...
