One of the main concerns of our client was to reduce as much as possible the energy consumption.<\/strong> With this in mind, our Technical Staff got involved to the maximum in the design of the tubular heat exchangers<\/strong>, paying special attention to the heat recovery section<\/strong>. We proposed our client different alternatives, advising him to get a minimum payback time to recover the initial investment.<\/p>\n Furthermore, our Technical Department proposed a customized design which included a special cladded insulation<\/strong> with the aim to minimise the heat losses to the environment, thus contributing to reduce the energy consumption.<\/p>\n In addition to dealing with the heat recovery<\/strong>, in the next sections we will go into the details of the design of heat exchangers for the processing of vegetable oils.<\/strong> <\/p>\n As stated earlier, it is not necessary to emphasize the critical importance of the\u00a0energy consumption<\/b>\u00a0in the costs when\u00a0refining oil<\/strong>. Using energy in the most economical way was the biggest concern for our client, hence\u00a0energy recovery<\/b>\u00a0and reduction in the consumptions became in our main objective in the\u00a0design of the tubular heat exchanger<\/strong>.<\/p>\n In this regard, our Technical Department checked different alternatives and advised our client to get a\u00a0payback time<\/b>\u00a0as short as possible.<\/p>\n Moreover our engineers checked the different phases of operation, as\u00a0start-up<\/b>\u00a0and\u00a0shutdown<\/b>, from the thermal and mechanical point of view.<\/p>\n All the above, together with the fact of the\u00a0restrictive working conditions<\/strong>\u00a0due to the\u00a0high temperatures and pressures<\/strong>, made using the\u00a0tubular heat exchangers<\/b>\u00a0with\u00a0corrugated tubes<\/b>\u00a0to be the\u00a0most suitable from the mechanical and thermal point of view<\/strong>.<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row custom_padding=”12px|0px|27px|0px” background_position=”top_left” background_repeat=”repeat” background_size=”initial”][et_pb_column type=”4_4″][et_pb_divider color=”#e9e9e9″ show_divider=”on” height=”5″ divider_weight=”2px” disabled_on=”on|on|off” \/][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section bb_built=”1″ admin_label=”section” custom_padding=”0px|0px|0px|0px” prev_background_color=”#000000″ next_background_color=”#000000″][et_pb_row admin_label=”row” custom_padding=”0px|0px|0px|0px” background_position=”top_left” background_repeat=”repeat” background_size=”initial”][et_pb_column type=”1_2″][et_pb_text background_position=”top_left” background_repeat=”repeat” background_size=”initial” _builder_version=”3.0.63″ background_layout=”light” text_orientation=”left” border_style=”solid”]<\/p>\n <\/p>\n Edible oils can be obtained from a wide variety of seeds, grains and nuts, being essential its\u00a0refining<\/strong>\u00a0to allow they can be used for\u00a0cooking purposes<\/strong>.<\/p>\n The fact is that vegetable oils and fats contain some impurities, being some examples\u00a0moisture<\/strong>,\u00a0lecithins<\/strong>,\u00a0insoluble solids<\/strong>,\u00a0free fatty acids<\/strong>,\u00a0waxes\u00a0<\/strong>and\u00a0metals<\/strong>\u00a0as sodium, potassium, magnesium or calcium.<\/p>\n Colour<\/strong>,\u00a0odour\u00a0<\/strong>and\u00a0taste<\/strong>\u00a0are also features that must be taken into consideration to get an optimal quality for the oil.<\/p>\n The\u00a0refining process<\/strong>\u00a0comprises several steps such as\u00a0bleaching<\/strong>\u00a0(removal of pigments) and\u00a0deodorising<\/strong>\u00a0(removal of odor and taste), but also other stages as\u00a0degumming<\/strong> (removing of hydratable and non-hydratable gums, i.e. lecithin),\u00a0neutralising\u00a0<\/strong>(to remove free fatty acids), and\u00a0dewaxing<\/strong>\u00a0(removal of waxes).<\/p>\n In all these phases, important changes of temperature (from ambient temperature up to 300 \u00baC) are involved.<\/p>\n <\/p>\n Due to the important temperatures reached along the process (close to 300 \u00baC) one of the key feature in this project was to recover as much energy as possible, minimizing the heat consumption. <\/strong><\/p>\n<\/blockquote>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”1_2″][et_pb_divider _builder_version=”3.0.63″ divider_style=”solid” divider_position=”top” hide_on_mobile=”on” height=”20″ disabled_on=”on|on|off” color=”#ffffff” show_divider=”off” \/][et_pb_image src=”https:\/\/www.sacome.com\/wp-content\/uploads\/2017\/03\/Proceso-refinado-aceite-vegetal-sacome.jpg” alt=”Vegetable oils refining process chart” title_text=”Tubular heat exchangers for minimizing energy consumption in edible oil refining” _builder_version=”3.0.63″ show_in_lightbox=”off” url_new_window=”off” use_overlay=”off” sticky=”off” align=”left” always_center_on_mobile=”on” border_style=”solid” force_fullwidth=”off” animation_style=”slide” animation_duration=”500ms” animation_intensity_slide=”10%” animation_direction=”left” show_bottom_space=”on” \/][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section bb_built=”1″ custom_padding=”0px|0px|54px|0px” _builder_version=”3.0.63″ prev_background_color=”#000000″ next_background_color=”#000000″][et_pb_row custom_padding=”33px|0px|0px|0px” background_position=”top_left” background_repeat=”repeat” background_size=”initial”][et_pb_column type=”4_4″][et_pb_text background_position=”top_left” background_repeat=”repeat” background_size=”initial” _builder_version=”3.0.63″ background_layout=”light” text_orientation=”left” border_style=”solid”]<\/p>\n <\/p>\n The heat exchanger of this project had to process different types of vegetable oil during its production cycle.
