Industrial Dehumidification

Petrochemical Industry

Dehumidification equipment has been used over the past 30 years for corrosion prevention in the refineries and chemical plants. Originally, dehumidification service was being used to lower the humidity inside tanks during blasting and painting application to prevent rust bloom from appearing on the surface. Today, dehumidification is used for numerous applications in these facilities but all for the same purpose, to prevent some type of corrosion.

Current Client Base

• Sasol Secunda – Tank Work
• Chevron Cape Town – Boiler and Tank Work
• Petro SA – Tank Work
• Engen – Boilers
• Port Marine Contractors / Dormac – Balast Tanks
• Foskor - Tanks

Benefits for using dehumidification:

• Aids in "holding the blast"
• No more weather related work delays
• Schedule a project any time of year
• Be able to work on a project 24 hours a day
• Increase production by 30% or more
• Apply coating across entire area at one time. No blast clean and prime daily
• Apply coating under proper conditions instead of ever changing natural conditions
• Reduces other costs (inspectors and out of service time) with shorter time schedules
• Reduction in Dust prior, during and after blasting.
• Lower LEL Levels
• Assist in curing times by expelling VOC’s from Tank
• Comfortable Working conditions (Lower Humidity)
• All the Machines come in an All Weather Housing that we have fabricated for Site Use

Use dehumidification in refineries and chemicals plants to prevent corrosion for:

• Traditional blasting and painting of internal tanks or vessel
• A catalyst removal to prevent polytheionic stress cracking
• A motor while it is out of service
• A turbine during an outage or shutdown
• External structures with full containment around them

Also Use Dehumidification in plants for:

• Concrete Sumps – To Remove moisture and apply coating.
• Humidity Control for workers to apply coating
• Under Controlled conditions – Furnaces/Boiler curing process/drying time for the curve of refractory
