Description
В насто щее врем процесс депарафинизации нефт ных масел осуществл ют путем кристаллизации твердых углеводородов из смеси сырь с растворителем и разделением твердой и жидкой фаз на барабанных вакуум-фильтрах, с последующей регенерацией растворител . При этом, наиболее сложной стадией депарафинизации, определ ющей производительность установок, вл етс процесс фильтрации.At present, the process of dewaxing petroleum oils is carried out by crystallizing solid hydrocarbons from a mixture of raw materials with a solvent and separating the solid and liquid phases on vacuum drum filters, followed by regeneration of the solvent. In this case, the most complicated dewaxing stage, which determines the capacity of the plants, is the filtration process.
Предлагаемый способ депарафинизации нефт ных масел позвол ет значительно увеличить скорость фильтрации созданием на фильтре пористого СЛОЯ твердых углеводородов. С этой целью часть петралатума (около 15% на сырье депарафинизации) распыл ют до частиц диаметром 0,02-0,3 мм, смешивают с холодным растворителем в отношении 1 :4 и ввод т в общий поток сырь , поступающего на фильтрацию. Сферическа форма частиц распыленного петролатума способствует разрыхлению образующегос на фильтре сло твердых углеводородов, вследствие чего повышаетс его проницаемость и скорость фильтрации смеси возрастает в 1,5 раза.The proposed method for the dewaxing of petroleum oils makes it possible to significantly increase the filtration rate by creating solid hydrocarbons on the porous LAYER filter. To this end, a part of petralatum (about 15% for dewaxing feedstock) is sprayed to particles with a diameter of 0.02-0.3 mm, mixed with cold solvent in the ratio of 1: 4, and introduced into the total flow of raw materials entering the filtration. The spherical shape of the particles of sprayed petrolatum promotes the loosening of the layer of solid hydrocarbons formed on the filter, as a result of which its permeability increases and the filtration rate of the mixture increases 1.5 times.
Предмет изобретени Subject invention
Способ депарафинизации нефт ных масел с применением фильтрации , отличающийс тем, что, с целью ускорени последней, часть твердого остатка петролатума распыл ют, смешивают с растворителем и добавл ют в поток сырь , поступающего на фильтрацию.A method of dewaxing petroleum oils using filtration, characterized in that, in order to accelerate the latter, a part of the solid petrolatum residue is sprayed, mixed with a solvent and added to the feed stream that is fed to the filtration.
