Purification of ion exchange resin with heat stable salt amine solution

  Cohesion a-98fm amine liquid, a special resin for amine liquid purification, is a general term for a class of organic alkali solutions with weak alkalinity
It is mainly used in the chemical industries such as petroleum, natural gas, coal chemical industry and synthetic ammonia to adsorb and remove impurities such as hydrogen sulfide or carbon dioxide from the feed gas
There are many alcohol amines
The rich amine solution after absorbing acid gas is regenerated by heating and distillation
The regenerated lean amine liquid is returned to the adsorption tower for recycling
In the process of amine desulfurization, a certain amount of anions will be accumulated in the system due to degradation, material introduction and other reasons
These anions will combine with organic amines to form heat stable salts (HSS)
These heat stable salts do not have the ability to adsorb acid gas and may corrode the equipment
Therefore, the amine solution needs to be purified to achieve the purpose of effective utilization of the amine solution and reducing the supplement cost of the amine solution
The amine liquid purification technology of kehaisi (Beijing) Technology Co
, Ltd
adopts a kind of fine particle anion exchange resin to realize the operation of the purification system with a low bed ion exchange equipment, which has excellent heat stable salt removal capacity
The core of this technology is the two processes of resin system adsorption of heat stable salt and alkali liquid regeneration of resin
Amine liquid purification equipment includes: low bed high-efficiency ion exchange process features: ① filtration system (protective type); ① The bed is low, the resin is fine, the filling is tight, the cycle is short, and the counter current regeneration; ② Fast low bed ion exchange system; ② Small equipment, easy to move; ③ Automatic alkali distribution system; ③ Low maintenance cost and simple resin replacement process; ④ Water circulation system; ④ The resin has high working efficiency and strong ability to remove heat stable salt (HSS); ⑤ Open PLC automatic control system ⑤ fast quality transfer, lower regenerant and rinsing water consumption, less waste liquid discharge strong alkaline anion exchange resin cohesion a-98fmcohesion a-98fm is a strong alkaline quaternary ammonium I anion exchange resin
It has excellent physical and chemical stability and operation characteristics
It can be used at various pH values and temperatures
Cohesion a-98fm is widely used in various chemical industries, as well as in the recycling and waste treatment of sewage treatment plants
