Abstract
СПОСОБ ОПРЕДЕЛЕНИЯ ТЕМПЕРАТУРЫ ВСПЬЯиКИ НЕФТЕПРОДУКТА 3 ОТКРЫТОМ ТИГЛЕ, включающий нагрев нефтепродукта вначале со скоростью 720 С/мин, а затем со скоростью 16 С/мин, непрерывное измерение и регистрацию температуры нефтепродукта, поджиг паров и фиксирование температуры вспышки, отличающийс тем, что, с целью упрощени процесса определени температуры вспьппки и повьшени его производительности за счет автоматического нахолсцени температуры изменений режиi ма нагрева нефтепродукта, нагрев нефтепродукта со скоростью 7-20 С/мин (Л производ т в закрытом тигле до по влени вспышки, после чего тигель открывают и нагрев нефтепродуктов продолжают со скоростью 1-б С/мин.METHOD FOR DETERMINING THE TEMPERATURE OF VSPYAIKI OF OIL PRODUCT 3 WITH OPEN TIGLE, including heating the oil at first at a speed of 720 C / min, and then at a speed of 16 C / min, continuous measurement and recording of the temperature of the oil, igniting the vapor and fixing the flash point, using a flash, recording the temperature of the oil, burning the vapors and fixing the flash point, using the flow of the flash, to set the flash temperature, burn the vapors and fix the flash temperature, to set the temperature of the oil, burn the vapors and fix the flash temperature, to set the flash, to set the temperature of the oil, to start burning simplifying the process of determining the temperature of the discharge and increasing its performance due to the automatic Naholscene temperature changes in the heating mode of the oil product, heating the oil at a speed of 7-20 C / min (L It is produced in a closed crucible until the appearance of a flash, after which the crucible is opened and the heating of oil products is continued at a rate of 1 b C / min.
Description
соwith
Изобретение относитс к температурным измерени м и предназначено дл измерени температуры вспьшки нефтепродуктов и других горючих жидкостей в открытом тигле,The invention relates to temperature measurements and is intended to measure the temperature of a bore of petroleum products and other flammable liquids in an open crucible,
Цель изобретени - упрощенце процесса определени температуры вспьшки в открытом тигле и повьшение его производительности за счет автоматического нахождени температуры изменени режима нагрева.The purpose of the invention is to simplify the process of determining the temperature of a plug in an open crucible and improve its performance by automatically finding the temperature of changing the heating mode.
Способ осуществл етс следующим образом.The method is carried out as follows.
Вначале исследуемую жидкость .нагрвают в закрытом тигле со скоростью 7-20 С/мин и определ ют температуру вспьшки, котора в закрытом тигле на 10-20 С ниже, чем температура вспьшки в открытом тигле, затем открывают тигель, измен ют скорость нагрева, провод т нагрев исследуемой жидкости со скоростью 1-6 С/мин и определ ют температуру, вспышки.Initially, the test liquid is heated in a closed crucible at a speed of 7–20 C / min and the temperature of the spike is determined, which in a closed crucible is 10–20 C lower than the temperature of the spike in the open crucible, then the crucible is opened, the heating rate is changed, the wire Heat the test liquid at a rate of 1-6 C / min and determine the flash point.
Способ основан на том, что температура вспышки воспламен ющихс жидкостей в закрытом тигле на 1020°С ниже, чем температура вспьшкиThe method is based on the fact that the flash point of flammable liquids in a closed crucible is 1020 ° C lower than the temperature of the flask.
жидкостей в открытом тигтех же ле.liquids in open tigtech le.
Пример. Проводитс определение температуры вспьш1ки нескольких нефтепродуктов в открытом тигле. Проба объемом 8,0 мл предварительно обезвоженного нефтепродукта помещаетс в тигель, который закрываетс шторным механизмом, и нагреваетс со скоростью 20С в минуту. Через каждые 6 с, т.е. через , с помощью электротокового разр дника проводитс поджиг паров нефтепродуктов. Температура нефтепродукта непрерывно измер етс с помощью датчика температуры и регистрируетс . При по влении вспьщ1ки паров в закрытом тигле шторньй механизм открывает тигель, и дальше проба нагреваетс со скоростью в минуту до по влени вспьшки паров уже в неограниченном объеме (в открытом тигле).Example. The determination of the temperature of several petroleum products in an open crucible is carried out. A sample with a volume of 8.0 ml of pre-dehydrated oil product is placed in a crucible, which is closed by a curtain mechanism, and heated at a rate of 20 ° C per minute. Every 6 s, i.e. The ignition of petroleum product vapors is carried out through an electric current discharger. The temperature of the oil product is continuously measured with a temperature sensor and recorded. With the appearance of vapor vaporization in a closed crucible, the storm mechanism opens the crucible, and then the sample is heated at a rate of one minute until vapor vapor appears already in an unlimited volume (in an open crucible).
Параллельно провод тс измерени температуры вспьшки тех же нефтепродуктов в соответствии с прототипом и ГОСТ 6356-75.Parallel measurements of the temperature of the same petroleum products are carried out in accordance with the prototype and GOST 6356-75.
Данные сведены в таблицу.The data are tabulated.
