On November 14, the flue gas desulfurization, denitrification and dust removal project of the 1.
2 million ton catalytic unit of Cangzhou Refining and Chemical Industry was successfully delivered, and the project quality fully met the requirements of relevant specifications, and the qualification rate of comprehensive tower welding was 100%, and the qualification rate of steel structure sampling inspection was 100%.
The construction cycle of the project is carried out in two phases, the first stage was completed during the overhaul last year, and the construction of the new waste heat boiler was started simultaneously with the main unit
.
After the new waste heat boiler was put into use, the operation effect was good, and the flue gas temperature dropped by about
30 °C.
The second phase started construction on April 11 this year, and the construction period lasted 217 days, completing the construction of dust removal pre-washing, desulfurization and amine liquid regeneration, denitrification, wastewater treatment, and sulfur unit transformation
.
Since the anti-corrosion FRP material is used for the first time in many parts of the device, Cangzhou Refining takes FRP quality management as the focus, and supervises the whole process from the production of equipment, pipelines and pipe fittings to installation to ensure that it fully meets the requirements of
the specification.
At the same time, special provisions are made for a large number of high-grade stainless steel materials, and three 100% material tests are carried out when entering the site, before installation, and after installation, and the parts of use are verified
one by one.
Increase the frequency of on-site joint inspections, find and solve problems in time, and finally achieve the goal of
"zero safety accidents and zero quality defects".
This time, CCCC has completed the hydrostatic test, stand-alone machine trial operation, chain commissioning, fire and heat preservation, civil acid prevention treatment, on-site sanitation cleaning, etc.
, and the device has been delivered to high
standards.
