【HaiChuan Modular Discussion】It only takes eight days to lift 4 6-tube loop reactors
Thread Content
From April 18 to 25, after eight days of continuous hard work, the installation of the 4 six-tube loop reactor units in Ningbo Jinfafa’s 1.2 million tons per year polypropylene thermoplastic elastomer (PTPE) and modified materials integrated production project was successfully completed.
The loop reactor is the core equipment in polypropylene plants; for this purpose, a modular and segmented prefabrication construction method was developed. The individual loop reactors are connected to one another using steel beams that are both bolted and welded together. Some of the connection beams are welded and insulated on the ground, and scaffolding for welding these connection beams is set up in advance. The lifting operation is carried out in four lifting modules and four lifting pieces. Compared with the traditional method of lifting individual pieces, modular lifting significantly reduces work at heights. For the lifting of the loop reactor, the \"single main crane lifting method\" is employed, whereby an 800-ton crawler crane is used for the main lifting while a 500-ton crawler crane is used to assist in lifting. The weight of each modular unit is 269 tons; the bottom elevation during installation is 6.5 meters, and the top elevation is 62.8 meters.
Where was the loop reactor designed? Where is it made?
I’m not sure if it’s this one: 【Major Equipment in the Chemical Equipment Industry】153-Circulating Reactor – first time it was transported out of the factory as a complete unit in China. https://bbs.hcbbs.com/thread-3332349-1-1.html (Source: Hua Hai Chuan Liu – Haichuan Chemical Forum Website)
The domestic design and manufacture of loop reactor technology have been in use for many years now. Thank you for the lifting diagram, I’ll use it as a reference in my future work.
