Benefits of technology

This new way uses both methods instead of just one more thing like evaporation or liquid extraction. It improves upon existing ways by making it faster than traditional techniques that require multiple steps. Additionally, this approach eliminates any unnecessary chemical reagents used during these processes reducing their impact on human beings' bodies and environment. Overall, this innovative technique makes better quality results without causing damage from excessive laborious procedures.

Problems solved by technology

The technical problem addressed by this patented technology relates to improving upon current methods that use specific chemical substances like naphtha or diesel oil at different stages of refining processes such as distilling, fractionating, purifying, etc., which can cause harmful environmental effects on workers who work near these materials.

Embodiment Construction

[0016] A method for measuring the distillate amount of crude benzene before 180°C, the steps are as follows:

[0017] (1) Select the measuring device: Beijing Dongxi Electronics GC4004A gas chromatograph (equipped with chromatography workstation), hydrogen generator (SPH-300) and air pump (SPB-3);

[0018] (2) Selection of chromatographic column: For the analysis of benzene series, the stationary liquid Apiezon L (Apiezon L): support (6201)=10%, the length of the chromatographic column is 3 meters; the stationary liquid Apiezon L is uniform Paint on the 6201 carrier of 60-80 meshes, weigh 5 grams of apisonone L, dissolve it in chloroform, add 50 grams of 6201 carrier, turn it constantly, after drying, pump it into a chromatographic column with an inner diameter of 3-4 mm and a length of 3 m through a vacuum pump , put it on the chromatograph and age it for at least 16 hours, and set it aside;

[0019] (3) Calculation of bulky components: use the area normalization method for ...

Abstract

The invention discloses a method for measuring distillate quantity of crude benzol before 180 DEG C. The method comprises the following steps of: 1, selection of a measuring device; 2, selection of a chromatographic column: for the analysis of the benzene serial matters, the ratio of a fixation fluid Apiezon L to a supporter(6201) is 10 percent, and the length of the chromatographic column is 3m; 3, calculation of components of the crude benzol: the area normalization method is selected for calculation; 4, apparatus conditions: the column temperature is the temperature programming and is raised from 140 to 180 DEG C, the vaporizing and the conversion temperatures are 180 DEG C, the carrier gas and the fuel gas are highly purified hydrogen gas, the pressure of the hydrogen gas is 0.20MPa, the pre-column pressure is 0.05MPa, the air pressure is 0.20MPa, and the sample size is 1.5 microliter; and 5, a large number of qualitative and quantitative analysis tests on the crude benzol according to the conditions: the benzene serial matters are completely distilled before 5 minutes, and the calculation method adopts that the distillate quantity (percent) of the crude benzol before 180 DEG C is equal to 100 minus the summation of area percents of all chromatographic peaks after 5 minutes.
