Molecular Sieve Membrane And Organic Solvent Dehydration Purification Equipment
Molecular sieve membrane pervaporation (steam pervaporation) is a new membrane separation technology with high efficiency, low energy consumption and low investment. It is suitable for the separation of constant boiling point, near boiling point mixtures and isomers, purification and recovery of organic solvent and removal of trace water. The molecular sieve membrane is a novel separation membrane material with "molecular sieve" function by in-situ "hydrothermal synthesis", which is used porous ceramic tubes such as alumina as supporting bodies. The dense and uniform molecular sieve membrane layer inherits the uniform pore size and hydrophilicity of the molecular sieve which makes it have excellent selectivity for dehydration and purification of various organic solvents that form azeotropic with water in the fields of petrochemicals, biomedicine, fine chemicals, new energy and environmental protection. The technology has been widely recognized and applied for its energy saving, environmental protection and easy operation. It is expected to replace traditional separation technologies such as distillation, extraction and adsorption in organic solvent dehydration and purification applications. The separation principle is as follows:
1) Low energy consumption, 60-80% energy saving compared with traditional methods, operating costs reduced by 60% and above, recovery rate >99%
2) No third component is introduced or produced during the process, and the product and environment are not contaminated
3) The equipment is compact and covers a small area.
4) Universally applicable, a system can be used for dehydration of various organic solvents
New energy: production of fuel ethanol and fuel butanol
Purification and recycling of various organic solvents in the pharmaceutical, chemical, printing, electronics, food and other industries
Alcohols: such as methanol, ethanol, propanol, isopropanol, butanol, pentanol, etc.
Ketones: such as acetone, methyl ethyl ketone, methyl t-butyl ketone, etc.
Esters: such as methyl acetate, ethyl acetate, butyl acetate, etc.
Ethers such as methyl tert-butyl ether, ethyl tert-butyl ether, etc.
Aromatic compounds: benzene, toluene, etc.
Other systems: THF, DMF, DMSO, etc.
The reaction process such as esterification, etherification and condensation removes the water formed by the reaction in situ, increases the conversion rate of the process, and reduces the energy consumption of solvent separation.
