Abstract
The utility model discloses a take off ester device for isooctane production, material jar export with pickling tower entry linkage, pickling tower export with first caustic wash tower entry linkage, export of first caustic wash tower and heat exchanger entry linkage, heat exchanger export with the water wash column entry linkage, water wash column export with the centrifuge entry linkage, centrifuge export divide into two branch roads, a branch road with second caustic wash tower entry linkage, another branch road with raffinate jar entry linkage, export of second caustic wash tower and product jar entry linkage. This device is through setting up filter, pickling tower, caustic wash tower, heat exchanger, water wash column and centrifuge, and the phenomenon that the production facility is corroded has effectively been avoided to acid esters in effective desorption material when promoting final product quality, adjust temperature and liquid flow through DCS control system, control is accurate, makes to take off continuous, stable the going on of ester process.
Description
Technical field
The utility model relates to the process for refining of Chemicals, belongs to petrochemical complex fine chemistry technical field, is specifically related to a kind of de-ester apparatus produced for octane-iso.
Background technology
Along with the fast development of Fine Chemical, the especially continuous application of biochemical technology, the Reverse Micelle System that octane-iso and other organism are formed is becoming a kind of and is integrating efficient, the separation method of the novel recovery protein of highly selective.Octane-iso will be widely used in biology,drug and chemical industry industry.By the situation of the current octane-iso output of China and the market requirement, octane-iso market is totally in the state that supply falls short of demand in recent years.China's octane-iso industry cannot meet domestic market demand and demand for exports in output always.According to forecast analysis, the relation between supply and demand in following 4 years will keep the state that supply falls short of demand, therefore is badly in need of improving the octane-iso output being used for fine chemical material market.In octane-iso preparation process, esters of gallic acid by product can be generated, the existence of this type of by product affects the quality of octane-iso product on the one hand, on the other hand under the high temperature conditions, acid esters reacts further and generates acid, and corrosion production unit, reduces equipment life, add production cost virtually, therefore need to clear up it.
Utility model content
Utility model object: the utility model object is for the deficiencies in the prior art, provides a kind of efficiency high, the easy-operating de-ester apparatus produced for octane-iso.
Technical scheme: the de-ester apparatus produced for octane-iso described in the utility model, comprise strainer, pickling tower, first soda-wash tower, interchanger, water wash column, sedimentator, residual liquid tank, second soda-wash tower and products pot, material pot outlet is connected with described pickling tower entrance, described pickling tower outlet is connected with described first soda-wash tower entrance, described first soda-wash tower outlet is connected with heat exchanger entrance, described heat exchanger exit is connected with described water wash column entrance, described water wash column outlet is connected with described sedimentator entrance, described sedimentator outlet is divided into two branch roads, one branch road is connected with described second soda-wash tower entrance, another branch road is connected with described residual liquid tank entrance, described second soda-wash tower outlet is connected with products pot entrance.
Preferably, for improving manipulation accuracy, simplify the operation flow process, and described strainer, pickling tower, the first soda-wash tower, interchanger, water wash column, sedimentator are connected DCS Controlling System with the second soda-wash tower.
Preferably, be impurity in further elimination material, be provided with scalable filtering membrane bottom described sedimentator, described scalable filtering membrane edge is connected with sedimentator inwall all the time, vertically moves in sedimentator.
Preferably, for monitoring de-ester effect in real time, at the bottom of the tower top of described water wash column and tower, acidity test instrument is set.
Beneficial effect: this device, by arranging strainer, pickling tower, soda-wash tower, interchanger, water wash column and sedimentator, the acid esters in effective elimination material, effectively prevent the phenomenon that production unit is corroded while promoting end product quality; By DCS Controlling System, temperature and liquid flow rate are regulated, control accurately, to make the carrying out that de-ester process is continuous, stable.
