In oil deodorization process, provide the heat source of heat medium mainly has high pressure steam, mineral oils, superheated steam, electric heating equipment, etc.Now the points mentioned below.
1, "high pressure steam"
With "high pressure steam as heat media,palm oil refinery plant high coefficient of heat transfer, safe, economic and reasonable.Because of its relatively low temperature difference and grease, can avoid the local overheating of grease, so is ideal hot media.The so-called "high pressure steam," here refers to only relative to the current oil for industrial use of saturated steam, in fact, deodorization used "high pressure steam" around its saturated vapor pressure of 6.86 Kpa, belongs to the medium pressure in chemical engineering, can be provided by the special small evaporation medium pressure boiler.General secondary processing of deodorization, evaporation is 0.5 ~ 1.0 tons/hour of medium-pressure small boiler can meet the production requirements.Day processing, for example, 75000 kilograms of deodorization device reads the heat medium of high pressure boiler, its technical help: heat output is 60 x 104 kcal/h;Design pressure 8.33 Mpa.Heat transfer area of 22.3 m2;Water capacity with a 0.552 m 3, when the normal operation of 0.473 m 3.Using the high pressure steam as heat medium for deodorization device heating device of pipes and pipe fittings can withstand the high temperature high pressure, high heat transfer equipment production and installation requirements,Steam pipe if the pipe quality and production technology to adapt to high pressure, unconditionally is unfavorable use the high pressure steam as heat medium.With "high pressure steam heating process as shown in figure 6-50.
2, mineral oil,
With good thermal stability of mineral oil as heat transfer media in industry application is widespread.Its characteristic is steady effect and easy operation.Our production has heat conduction oil furnace and heat conduction oil series...
