    Notes: The general problem of heat and power integration in process networks is complex and to date not fully understood. The subject covers site combined heat and power, on-plant power generation, heat pumps, and refrigeration systems. This paper is the first of a two-part series and explains the concept of “appropriate” heat engine and heat pump placement in process networks based on a fundamental new insight. “Appropriate” placement takes advantage of integration opportunities with the remainder of the process and yields marginal efficiencies far greater than could be achieved through stand-alone heat engines. Conversely, “inappropriate” placement can never offer an advantage over stand-alone systems. Part II describes procedures for preliminary design, involving heat engine, and heat pump equipment selection and performance assessment.

    Notes: In Part I, criteria for heat engine and heat pump placement in chemical process networks were derived, based on the “temperature interval” (T.I) analysis of the heat exchanger network problem. Using these criteria, this paper gives a method for identifying the best outline design for any combined system of chemical process, heat engines, and heat pumps. The method eliminates inferior alternatives early, and positively leads on to the most appropriate solution. A graphical procedure based on the T.I. analysis forms the heart of the approach, and the calculations involved are simple enough to be carried out on, say, a programmable calculator. Application to a case study is demonstrated.Optimization methods based on this procedure are currently under research.

    Notes: An ARCTM or similar experimental apparatus provides the transient temperature history of a chemical system under adiabatic conditions. The information obtained has several applications in the design and operation of industrial systems. Of particular interest is use of the adiabatic kinetic data to define “intervention strategies” based on “allowable response times” during an emergency.The time-temperature behavior of industrial reactors can be simulated over a limited temperature range by matching the “thermal inertia” (or φ-factor) of the experimental system to that of the full-scale system. This approach is applicable even for complex reactions, minimizes the extrapolation of data, and allows the use of simple models for data interpretation. Simulation results directly give the time available to respond in the event of a thermal runaway; this in turn defines the design requirements for an intervention scheme (e.g., emergency cooling, blow down, quench, etc.). The chosen intervention system can be tested experimentally prior to and/or during process start-up.
