Study of Using Solar Thermal Power for the Margarine Melting Heat Process.

摘要: Margarine as a raw material has multiple uses in the production of bio-organic materials such refined oil and butter. It passes through many industrial stages before beginning process refining packaging it to consumer. One these important is melting process, which wastes an immense amount thermal power. The large rate power consumption occurs due huge reservoirs margarine stored (500 m3–1500 m3 Savola International Company-Suez Gulf region-Egypt). With drawing from cost time intensive solid state at environmental temperatures. Dry saturated steam passed heat exchanger pipes inside reservoir melt required margarine. In some cases, this can take up 8 h summer 12 winter, be amplified by loss energy throughout day, especially during night periods. Moreover, boilers that use heavy fuel or natural gas cause serious damage result emissions, carbon oxide nitrous compounds. In contrast, solar one cleanest environmentally friendly renewable energies should invested alternative source for As mentioned before, considered heating consumes energy. Therefore, play vital role Generally, temperature requirements applications range 60 °C 260 °C. Cylindrical PTC systems look very promising delivering 95 °C–350 °C delivery [1]. For applications, operating design conditions collectors well above desired application ensure stability operation. flat plate evacuated tube are eliminated study previous reason its lower efficiencies compared against [2]. This why medium medium–high used [3,4]. Most processes food industry milk products, vegetable, meat, fruits, beer run temperatures below near 100–130 °C. addition, cleaning pasteurizing, sterilizing, drying, hydrolyzing, distillation, washing, polymerization, cooking conducted under [5,6]. Thus, switching source, energy, savings decrease negative impacts on environment. The requires viable more effective problem originally emerged when Savola's company officials (Savola Company Suez region-Egypt) decided optimize time, process. They summarized their problems into following points: The melts takes than obtain 100–200 melted per day. Which costs equivalent 476,120 day (100,000 $/month). Reduction CO2, NO2, CO emissions must according laws. After reviewing configuration using clean seemed most solution. Egypt great potential calculated 6–7 kW h/m2/day global radiation region-Egypt [8]. utilize vast untapped aim research present feasibility study, assessing impact instead conventional boiler. Water–steam and/or Therminol-VP1 [7] HTO utilized representing two different configurations. data results (config1) with PTC–water (config2) PTC–Therminol (config3) hourly parameter ($/h). plan organized follows: The configurations proposed performed limits investigated. The mathematical model represents constructed. Three cases (solar direct vapor generation (two configurations) was configuration). Practical analytical solutions studied executed. solar desalination system (SDS) software package (a part (REDS) were developed authors) all units [8–11]. 2. Melting Heating Process 2.1.
