Vapor & Gas Suppression


VGS – Proprietary Vapor & Gas Suppression Process

Reduce Hazards, Downtime and Cost with our “Safer, Greener, Cleaner” Approach.

VGS is a proprietary aqueous solution engineered to reduce VOC’s/ LEL’s; H2S, SO2 gases on contact, eliminating the need for multiple water fills, steam or extensive nitrogen purging. Penetrates and releases layers of solids from metal surfaces while inhibiting re-adherence in lines downstream. A-Safe’s VGS Process can be used as a stand alone cleaning treatment or in combination with other cleaning processes such as hydroblasting and dry-ice blasting.

Reduces time for clearing/cleaning filter pots, caustic scrubbers, flare stack blow down tanks, acid tanks, etc. by up to 80%.

A unique, scientific breakthrough in encapsulation and emulsification technology, VGS increases profitability, productivity and safety of fractionation and transportation of natural gas liquids.

VGS is a biodegradable and environmentally preferred industrial concentrate having a neutral pH. It is non-corrosive, contains no butyls or citrus components and is safe to handle and store. Product # 251; DOT Shipping Class 55; Non-Hazardous.

Successful Projects:

NGL filter pot element change: VGS concentrate is pumped into the filter pot along with water. A small nitrogen flow is established for about an hour at the bottom of the pot to produce agitation. The water is discharged and the pot tested to assure LEL’s have been reduced. Only one wash is usually required for entry.

Reduce VOC’s in caustic KOH treater and flare stack blow down tank: VGS concentrate is introduced with water after the majority of hydrocarbons have been recovered. A nitrogen flow is established for about two hours to create agitation. The product has proven to be so effective, that LEL’s are reduced and H2S gas is virtually eliminated in a single wash. Additionally, build-up of solids in discharge lines was reduced, increasing flow. Similar methods were used to reduce VOC’s in the flare stack blow down tank and acid tanks.
