EMICS CHEMTECH LLP is the Best in class provider for chemical cleaning services. New construction facilities often undergo a cleaning process prior to start-up. Piping and vessels may contain a variety of debris, scale, oxides and oil that must be removed for the planteffectively run.
To continue to operate a peak efficiency, processsystem, vessel and pipelines must be kept as clean as possible. Some of the normal by-product of operating processes create deposits ranging from scale to sludge precipitates and even metal deposits. These types of build-up foul the vessels and piping and can significantly reduce system efficiency, eventually causing plugging and failure of the unit.
CATEGORIES OF CHEMICAL CLEANING
The two major categories of chemical cleaning are pre-operational chemical cleaning and post operational chemical cleaning
A) PRE-OPERATIONAL CHEMICAL CLEANING
Its performed to remove any foreign material remaining from the construction activates either on the pipe or system fabrication. Major consideration in the pre-operational phase includes mill, scale,corrosion product, weldscale, oil, grease, sand, dirt, temporary protective coating, and other construction debris.
B) POST-OPERATIONAL CLEANING
Performed for severalreasons, including reduced heat transfer, reducedflow, safety (eg.H2S, pyrophoriciron, LEL, ammonia, etc), reduced surface area, access to full inspection and more. The type and frequency of post-operational cleaning varies with system design,operating requirements,and history of operation and fluid/water treatment.
Different methods used in chemical cleaning are follows
- Fill and soak method
- Fill and circulate method
- Nozzle cleaning method
