Definitions

  • the invention relates to the sector of maintenance of industrial systems that use oils at high temperatures and, more in detail, the invention relates to a method for degasification of diathermic oil, i.e., the elimination of gases present therein.
  • Gas and light fractions are currently eliminated through a method based on an oil distillation process, thanks to the use of apparatus similar to distillers. These apparatus, once connected to a bypass of the circuit, allow elimination of the gases via the presence of a vacuum chamber. However, this procedure is implemented with the system operating and the oil passes through the vacuum chamber at the operating temperature of around 250°C - 270°C, temperature maintained constant for the entire process.
  • Document DE 22 05 466 A1 refers to a method for degasification of diathermic oil, comprising the steps of:
  • the invention aims to overcome these limits, defining a new method able to obtain elimination of the gases and light fractions at low temperatures without further stress and degradation to the oil, avoiding possible further degradation of the molecules, simultaneously restoring the system to safe conditions and significantly lowering the risk of fire, hence also guaranteeing greater safety for the operators.
  • said value ⁇ T is between 20° and 30°C.
  • said step of regulating the temperature of said diathermic oil comprises the step of heating said diathermic oil, or the step of cooling said diathermic oil.
  • a step of mechanical filtration and a step of magnetic filtration for said diathermic oil there is provided a step of mechanical filtration and a step of magnetic filtration for said diathermic oil.
  • said step of collecting the gas released and sending it to a discharge point comprises a step of physical-chemical filtration of said released gas.
  • Treatment of the oil does not take place in constant conditions of operating temperature of the system, but in programmed situations in which the temperature of the oil can be regulated and modulated according to processing needs. Therefore, it starts from lower temperatures around the flash point (detected by the analyses), to slowly and gradually reach the operating temperature. In this way the gas is eliminated naturally following the normal start-up process of the diathermic oil system, without incurring any further stress and degradation of the fluid.
  • the first steps of the process according to the invention are steps of analysing and evaluating the diathermic oil to be treated: determining the flash point and the distillation curve are the most important operations of the entire procedure, and are carried out analytically in the laboratory using ASTM methods applied to a sample of diathermic oil collected from the system.
  • the flash point of a new diathermic oil corresponds to around 200°C and its reduction to 130°C is tolerated. If this value drops further, it means that gas has formed inside the oil, which is thus easily inflammable in the event of leakage from the circuit and in contact with an external ignition source.
  • the distillation curve instead allows an evaluation in percentage of the volume of gas generated in the oil to be implemented, indicatively detecting it in several concentration levels (considering 0% the starting point of gas formation, and then measuring 2%, 5% and 10%).
  • Table 1 provides an example of the flash points and of the distillation curves detected on five different samples of diathermic oils.
  • Table 1 SAMPLE A SAMPLE B SAMPLE C SAMPLE D SAMPLE E Type of oil Mineral Mineral Synthetic Synthetic Mineral Flash point °C (T0) 120 75 80 130 100 Distillation curve: start (IBP)°C 180 150 130 200 140 2% 220 200 210 270 190 5% 270 240 245 300 240
  • the central step of the degasification process takes place in a bypass, parallel to the system, with the circulation pump of the system operating, and can be carried out both with the system not at operating temperature, and hence with cold diathermic oil, and with the system active, with diathermic oil at the operating temperature.
  • the first step provides for regulating the temperature of the oil, using the heating means of the system, taking it to the temperature T0 lower than the flash point measured.
  • the vacuum is applied to the diathermic oil, with a preset pressure value P0 and for a predetermined time interval ⁇ t0, both values defined by the distillation curve, sufficient to suck all the gases released at the given temperature T0.
  • the diathermic oil is re-introduced into the system at the temperature T0.
  • the subsequent steps substantially involve the same operations of applying the vacuum carried out at different levels of incremental temperature T1, T2, T3,... Tn increasing in steps of an interval ⁇ T between 20° and 30° C.
  • the oil is gradually heated inside the system using its own heating means.
  • the first step involves reducing the temperature of the oil, taking it to the temperature T0 lower than the flash point measured.
  • the oil is normally cooled using blast chillers of known type, positioned in series, inside which the oil is made to flow before reaching the step of applying the vacuum.
  • the temperature of the diathermic oil collected from a system that is operating, and therefore presumably around 250°C, can be lowered to around 70°C, temperature usually lower than the flash points found on many diathermic oil systems.
  • the vacuum is applied to the diathermic oil with a given value and for a given time interval, determined by the distillation curve and necessary to suck all the gases released at that given temperature.
  • the diathermic oil is re-introduced into the system at the temperature T0 and immediately taken to the operating temperature using the heating means of the system.
  • the subsequent steps substantially involve the same operations of applying the vacuum carried out at different incremental temperature levels T1, T2, T3,... Tn increasing in steps with an interval ⁇ T between 20° and 30° C.
  • modulation of the vacuum varies as a function of the incremental temperatures of the oil T0, T1, T2, ... Tn to which the oil is taken during the method for degasification.
  • the time interval for application of the vacuum is also determined, at the different incremental temperatures of the oil T0, T1, T2, ... Tn, based on the amount of diathermic oil present in the system, expressed in litres, and based on the distillation curve.
  • FIG. 1 there is illustrated a diagram of the main components of an apparatus for degasification of diathermic oil arranged to implement the method described above, in the case of use in a bypass with a system that is not operating.
  • Said apparatus essentially comprises:
  • filter means F1 and F2 of the inflowing diathermic oil Upstream of said vacuum chamber 1 there are provided filter means F1 and F2 of the inflowing diathermic oil, adapted to carry out initial cleaning of the oil and facilitate the subsequent work of the vacuum pump.
  • Said filter means comprise a metal mesh filter F1 for sludge, and a magnetic filter F2 for ferrous impurities.
  • Said apparatus also comprises a liquid trap TR interposed between said vacuum chamber 1 and said vacuum pump P1, adapted to retain, by sedimentation, any residues of oil sucked with said vacuum pump P1.
  • said apparatus comprises a vacuum relief valve Vr that has the task of regulating the inflow of outside air into said trap TR.
  • Said vacuum relief valve Vr substantially prevents implosion of the trap TR, and consequently of the vacuum chamber 1, placing the whole vacuum circuit of the apparatus in communication with outside environment upon reaching a minimum preset vacuum pressure inside the vacuum chamber 1. Opening or closing of said vacuum relief valve Vr can take place automatically or via manual regulation by an operator.
  • blast chillers A1, A2 and A3 connected in series are placed upstream of the vacuum chamber 1, as illustrated by way of example in Fig. 2 .
  • said apparatus comprises a condensation device C interposed between said vacuum pump P1 and said activated charcoal filter F.
  • Said condensation device C comprises a refrigerator 2 loaded with Freon, a plate heat exchanger 3, a sensor 4 to detect the temperature, an electronic regulation and control unit 5.
  • Said plate heat exchanger 3 comprises two inlets (a first inlet for the gases released from the vacuum pump P1 and a second inlet for the cooling Freon) and two outlets (a first outlet for the heated Freon and a second outlet for the cooled gases with the condensed light fractions removed). Said two inlets and said two outlets are placed opposite so as to obtain the best possible heat dissipation.
  • the condensation procedure takes place via a preliminary setting of the temperature required to reduce the light fractions (2° - 5° C) via the electronic regulation and control unit 5.
  • the detection sensor 4 and the electronic control unit 5 act on the condensation device C switching the refrigerator 2 on and off based on the temperature required to maintain the temperature set on the gases exiting from the plate heat exchanger 3.
  • Said condensation device C also allows any moisture and water vapour present in the gases released to be eliminated.
  • the condensation temperature to be set with the electronic regulation and control unit 5 is between 10° and 20° C.
  • said apparatus comprises a calibrated valve Vc for recovery of the gases released from said diathermic oil placed downstream of said vacuum pump P1 along a circuit for connection with the trap TR, or more generically with the outlet OUT of said vacuum chamber 1.
  • This calibrated valve Vc allows the vacuum pressure inside said vacuum chamber 1 to be regulated to be able to improve the performance of the apparatus, the result of the method for degasification and its safety.
  • the apparatus described can be operated manually by an engineer who, as a function of the information collected on the state of the oil and of the system before the start of operation, regulates the heating or cooling means and the vacuum pump based on the tables described above.
  • said apparatus can comprise a control unit capable of performing the aforesaid regulations automatically. After the necessary data has been entered, said control unit can regulate the vacuum value and the operating temperature directly.
  • the two samples of diathermic oil are n° 402 manufactured by the company Silicart with an initial flash point of 118°C and n° 332 manufactured by the company Clea with an initial flash point of 110°C.
  • the gas chromatogram in black refers to headspace analysis of the oil C after the treatment, while the gas chromatogram in red refers to headspace analysis of the same oil C, before the treatment.
  • the high temperature treatment is not effective in reducing volatile substances, i.e. in increasing the flash point.
