Design of water and heat recovery networks for the simultaneous minimisation of water and energy consumption

This paper describes procedures for the design of processes in which water and energy consumption form a large part of the operating cost. Good process design can be characterised by a number of properties, amongst the most important are: efficient use of raw materials, low capital cost and good operability.In terms of thermodynamic analysis these processes can be characterised as being either a “pinch” problem or a “threshold” problem. This paper concentrates on developing designs for problems of the threshold type. Most of the problems discussed by previous workers have been of this type. With these properties in mind this work looks at the design of integrated water and energy systems that exhibit the following features: 1. minimum water consumption, 2. minimum energy consumption, and 3. simple network structure. The approach applies for single contaminant.It is shown that the water conservation problem and the heat recovery problems can be de-coupled and the water conservation options should be established first. It is then shown that the number of heaters and heat recovery units required for the system, the quantity and type of hot utility needed for the plant and the complexity of the heat recovery network can all be determined without having to design any heat recovery network. This allows the engineer to select the better water conservation option before embarking on the design of the heat recovery network. For this type of problem the design of the heat recovery network itself is usually simple and straightforward.     

Parameters analysis on organic rankine cycle energy recovery system

A systematic algorithm of parameters analysis on an Organic Rankine Cycle (ORC) energy recovery system has been proposed. It includes thermodynamic analysis, economic evaluation and sensitivity analysis, and economical design parameters study. The cases studied indicate that the effects of the design parameters (T_H, T_L, T₁, and E_g) on the system's economic feasibility are very significant, and there is an economical combination of those parameters. Annual operation hours, electricity unit cost, and equipment manufactured cost are also important parameters to the integrated benefit of an ORC recovery system. Moreover, it shows that the recovery of low temperature, gas phase waste heat by an ORC system is economically unattractive; however, the recovery of low-pressure waste steam by an ORC system has been shown to be a high potential for moderate capacity plants.

Effective use of surplus LP steam to maximize cracker throughput and reduce energy consumption

Steam cracking is a fundamental application of olefin production which is the building block of petrochemical complex. Continuous efforts are being made to optimize the cracker performance by process-side optimization. The cracker furnace flue gas, which has a huge quantum of low-grade energy, is getting lost from the stack; a waste heat recovery system is being employed to generate ow-pressure steam. This also helps in the reduction of induced draft fan suction temperature. However, if there are no low-pressure steam consumers, the steam requires to be vented or partial heat recovery to be done. The lower heat recovery through waste heat recovery boiler restricts the cracking furnace throughput due to a higher suction temperature of the induced draft. A detailed steam network study has been done for a petrochemical complex having various downstream plants to maximize heat recovery as well as furnace throughput. For any equipment in question, to use a lower steam, it was a challenge to switch over from relatively higher-pressure steam to lower-pressure steam due to equipment design consideration as well as operating temperature requirement of any process. Different alternatives were thought of and evaluated based on process requirement, possibility of steam venting of other level steam, and cost of modifications. The outcome of this study has helped to utilize the low-pressure steam. The study indicated that for optimization of cracker performance, in addition to process side, there is a scope to improve on flue gas side operation also.

Efficiency of two-step solar thermochemical non-stoichiometric redox cycles with heat recovery

Improvements in the effectiveness of solid phase heat recovery and in the thermodynamic properties of metal oxides are the most important paths to achieving unprecedented thermal efficiencies of 10% and higher in non-stoichiometric solar redox reactors. In this paper, the impact of solid and gas phase heat recovery on the efficiency of a non-stoichiometric cerium dioxide-based H₂O/CO₂ splitting cycle realized in a solar-driven reactor are evaluated in a parametric thermodynamic analysis. Application of solid phase heat recovery to the cycling metal oxide allows for lower reduction zone operating temperatures, simplifying reactor design. An optimum temperature for metal oxide reduction results from two competing phenomena as the reduction temperature is increased: increasing re-radiation losses from the reactor aperture and decreasing heat loss due to imperfect solid phase heat recovery. Additionally, solid phase heat recovery increases the efficiency gains made possible by gas phase heat recovery.     

BCHP design for dual phase medical complex

Comprehensive value engineering conducted for a Midwest (USA) developer client focused upon their architect/engineer proposals for a nominal 100,000 m² medical facility comprising under Phase I, two 12 storey medical office towers and adjacent six (6) storey hospital. Client's architect-engineers had originally proposed constructing separate central heating and cooling plants for each of their (i.e., originally designed) Phase I buildings. Phase I plant layout and interim study results demonstrated significant building space and annual owning savings over conventionally designed individual (i.e., in situ) building heating and cooling plant and incorporated gas and steam turbine driven chillers and integrated gas turbine driven synchronous generator resulting in an estimated 2.6 year simple payback. However, subsequent client Phase II project scope expansion undertaken prior to commencing above referenced Phase I BCHP plant construction required major design changes. The subsequent Phase II redesign resulted in the elimination of higher cost heat recovery steam generator which was replaced with a low cost novel hybrid steam generator utilizing a non-toxic, hot-oil energy recovery system; replacement of costly condensing steam turbine with a less expensive combination serial back pressure steam turbine and indirect single stage absorption chiller bottoming cycle; the later sized for the additional Phase II new office tower subsequently required by client all without exceeding Phase I project budgetary criteria.
