Abstract

The invention discloses a hydrocarbon oil dewaxing experimental instrument and an experimental method thereof. According to the invention, a solvent cylinder and a filter cylinder which are the same as a sample cylinder in specification and dimension and have interchangeability are additionally arranged on the basis of the traditional hydrocarbon oil dewaxing experimental instrument, and the solvent cylinder, the filter cylinder and the sample cylinder are simultaneously positioned in a same cold bath, so that the consistency of solvent temperature, filter temperature and sample temperature is ensured in an experimental process, the difficulty of experimental operation and temperature control which needs to be respectively carried out on the sample cylinder, the solvent cylinder and the filter cylinder in the experimental process, the system errors of an experimental result are decreased, and the parallelism of the experimental result is enhanced; and the automation of solvent addition is realized by adding a solvent metering addition system, so that the labor intensity of manual operation in the experimental process is reduced, the contact opportunity of an experimental operator and toxic chemical components contained in the experimental solvent is reduced, and the occupational health of the experimental operator is favorable.

Description

technical field

[0001] The invention relates to an experimental instrument and its experimental method, in particular to a hydrocarbon oil dewaxing experimental instrument and its experimental method. Background technique

[0002] There are many methods of dewaxing hydrocarbon oil, the most commonly used method is solvent dewaxing. The principle of solvent dewaxing is to mix the raw material oil and the dewaxing solvent evenly, and then cool it under controlled conditions, and use the solvent's property of insoluble or slightly soluble in wax components at low temperature, but soluble in other components except wax , to crystallize the wax in the solution, filter the solution to obtain dewaxing filtrate and wax paste, and then respectively go through solvent removal to obtain dewaxed oil and oily wax.

[0003] In the prior art, the solvent dewaxing experiment instrument used in the laboratory for hydrocarbon oil dewaxing experiment generally only has one sample cylinder, an...
