Natural circulation ion membrane caustic soda first start-up cleaning

This post was last edited by sunjl1981 on 2013-1-6 20:08 for help: Our factory is about to start up. How should the specific pipeline purging, equipment cleaning and water circulation be carried out? Our process is Asahi Kasei's natural circulation ion membrane caustic soda. # , , &
In the initial stage of driving, you should have on-site guidance from Asahi Kasei technicians.
The original poster, I believe your company should already have the document preparation work before starting the test run of each device! If you didn't prepare this in advance, how could you compile a test run plan and plan? If possible, please introduce the situation of your factory!
Every company has its own operating model! The preparation before we drive is very complicated. 1. Check whether the equipment, pumps, pipelines, instruments, valves, tests, etc. are normal. 2. Contact each position to confirm whether each material is in normal supply. Perform salt water circulation first: route: D-150 to T-160 to D-160 to D-170 to D-260 to T-310 to primary salt water. Then conduct a comprehensive inspection of the resin tower.
Refer to what you need to pay special attention to when driving for the first time. http://bbs.hcbbs.com/viewthread.php?tid=263156&page=1#pid1233852
When cleaning the natural circulation ion membrane caustic soda for the first time, install the dummy membrane (that is, plastic), follow the operating procedures, etc. (without power), recirculate, calibrate the instrument, etc., and do it carefully for a week. When officially driving, pay attention to the exhaust gas (safety)
Before each factory starts up for the first time, a lot of preparation work should be done, such as setting up a production preparation team, conducting a lot of training, writing operating procedures, pipeline equipment cleaning and purging plans, pressure test plans, chemical input and commissioning plans, etc.

Very simple, but very tedious. The steps are roughly as follows:: The process gas is purged and the pipeline water is cleaned for 3-5 days. After completion, clean each circulation tank with a good surface. The water is heated and circulated for 3-5 days and the conductivity is analyzed. Finally, the filler is heated and circulated for 3-5 days and the iron content is analyzed.
