Catalytic cracking catalyst

2009-03-07View Original

Thread Content

The impact and wear caused by catalytic cracking catalysts on valves are extremely severe; if automatic feeding is used, the wear exerted by pure catalysts on ball valves is something that can be easily imagined. Do you have any experience in using this approach? How long will this valve likely last, and which manufacturer made it? Thank you for providing this information!

It can be used for 3 years without any problem; mine has been running for 3.5 years now and has never broken down. It comes as part of the supporting facilities in Shanghai. From Shanghai Jianhao.

There is wear and tear; it just needs to be replaced every two years.

Correction: It is Shanghai Haojian Electrical Co., Ltd. Valves generally last 2-3 years. It’s described on the forum.

It wears out frequently and is generally replaced often, especially the catalyst loading/unloading system.

Ball valves can generally last for over 2 years, while catalytic gate valves must be kept fully open or fully closed

Wear is inevitable, especially in the descaling line valves; wear is significant at temperatures around 300 degrees. We replace them every 2 months...

The valve body is made of 20G steel, while the throttle cone is made of austenitic steel.

Valves on typical catalyst pipelines are equipped with corundum linings, allowing them to withstand temperatures of over 500 degrees. Wear-resistant.

It’s volume-based measurement, right? Is it accurate?

Yes! The valves wear out quite severely during this process! Valves made of stainless steel would be better!
