Abstract

The invention relates to the field of chemical separation and bioengineering mechanical equipment, in particular to a subcritical fluid continuous isobaric extraction and separation device system and extraction and separation process, the device system consists of a subcritical fluid medium source, a pressurized subsystem, and a continuous extraction subsystem 1. The separation subsystem and the pressurization circulation subsystem are composed of the same step-by-step pressurization or step-by-step extraction stages of the continuous extraction subsystem. Applying the extraction and separation process implemented by this device system, through the systematic process operation, the extracted subcritical fluid or supercritical fluid in the silo after the extraction is completed enters the corresponding separation subsystem to start separation, and the discharge valve is opened periodically, Unload the extract separated by the separation subsystem. The technology device of the invention has high degree of automation, reliable operation, reasonable process flow of the device system, and realizes sub-extraction separation such as continuous subcritical fluid, energy saving and zero emission, excellent manufacturability, and excellent separation effect.

Description

[0001] 1. Technical field

[0002] The invention relates to the fields of chemical separation and bioengineering machinery equipment, in particular to a subcritical fluid continuous isobaric extraction and separation device system and an extraction and separation process.

[0003] 2. Technical background

[0004] Subcritical fluid extraction and separation technology is another green chemical technology following supercritical fluid extraction and separation technology, and is being widely used in the field of extraction and separation. However, most of the existing subcritical fluid extraction devices are intermittent devices with quick-opening and sealed structures, which have low production efficiency and high energy consumption; frequent opening of the extractor has low safety and reliability and causes a great loss of extraction fluid, which is a serious constraint. application of this new technology.
