Leaders in Gas Scrubbing
Hygrade has been treating waste gas streams since the 1970’s and during this time we’ve founded an enviable reputation for the design and manufacture of air pollution treatment systems.
Gas Scrubbing is a diverse process used to remove noxious or unwanted contaminants from gaseous streams required as a process requirement or for environmental protection. Every circumstance is different which is why we offer no off the shelf systems, all our technologies are tailor made to offer guaranteed removal efficiencies, low running costs and long-term service.
Gas Scrubbers suit a wide variety of applications that require mass removal from a gas stream. The flow rate, contaminant concentration, temperature and required removal efficiency will all affect the scrubber design which is why Hygrade offer free consultation to its clients helping to choose the correct scrubbing package.
Our packed tower scrubbers, venturi scrubbers, gas absorption systems and stripper columns are all available in a wide range of thermo plastics and GRP. When required we offer BS4994 standards ensuring the highest quality with optional laminate testing and commissioning. We also can provide all associated ductwork, pipework, dosing systems, controls, instruments and fans necessary to complete the project.
Relining and Refurbishment
Scrubbing equipment is subject to highly corrosive conditions from concentrated chemicals often at elevated temperatures. It is therefore vital to maintain the internals of any scrubbing equipment to avoid failures or more dangerous leaks.
Hygrade provide cost effective relining and refurbishment of scrubbing equipment to ensure a longer life span. Refurbishments range from smaller patch repairs through to complete overhauls replacing internals, dosing systems, pumps and fans.
