Problems solved by technology

Due to the large number of outlets in the fixed bed separation system, large manual operation errors, and easy material loss, the yield has remained low for many years. The original separation system can no longer meet the current production level. In order to improve the extraction of isoleucine Production level, to change the current situation of high consumption, low output, and low labor productivity of the fixed bed centrifugation system, the company decided to introduce an automated continuous centrifugation system and apply it to the large-scale extraction production of isoleucine

Embodiment 2

[0049] A control method for any automatic continuous separation system, which includes the following steps:

[0050] 1) Set the process parameters of the system through the PLC controller;

[0051] 2) The PLC controller collects and processes the data of the flow sensor, pressure sensor and liquid level sensor in the system, and transmits it to the host computer;

[0052] 3) The operator monitors the operating status of the system and various process parameters through the host computer, and conveniently sets the operating parameters of the system according to the authorization level; including system pressure, flow rate, multi-way valve operating speed, stepping speed, System exchange time, the process position of each column in the system and the material level of each raw material tank and intermediate tank, etc.;

[0053] 4) When there is an abnormal situation in the system, the upper computer can give an alarm prompt to the operator in time, and the system is connected w...

Abstract

The invention relates to an automatic continuous ion-exchange system and a control method for large-scale extraction production of isoleucine. By the innovation in various aspects of the original process, such as the feeding and discharge mode, the washing mode, the concentration of regenerated hydrochloric acid and introducing of automation equipment, the automatic continuous ion-exchange system is applied successfully. After the method is applied, the beneficial effects are significant. The automatic control system is applied, the number of operation personnel is reduced, the labor intensity is reduced, and labor productivity is increased. Water-using and vapor-using are reduced largely. Environment-friendly and energy-saving work is promoted powerfully, and the site area of the system is reduced.

Description

technical field [0001] The invention relates to the field of large-scale extraction devices for isoleucine, in particular to an automatic continuous separation system and a control method for large-scale extraction and production of isoleucine. Background technique [0002] Ion exchange is a very important step in the extraction process of isoleucine. Its main purpose is to purify the product and remove impurities in the material to achieve the purification effect. Traditional ion exchange is divided into fixed bed (Fixed Bed), pulse bed (PulseBed), simulated moving bed (Simulated Moving Bed) and other processes. The original separation system of our factory is a fixed-bed ion separation system, which operates all steps in a batch process one step at a time. [0003] Continuous ion exchange technology is a completely innovative separation process technology, which is developed on the basis of traditional fixed bed resin adsorption and ion exchange process combined with the ...
