FQE® Solvent-H+ offers unsurpassed performance in dissolving and preventing solid hydrocarbon deposits that are found in heat exchangers, vacuum tower bottoms, coker fractionator bottoms, oil storage tanks, and other hydrocarbon processing equipment. The formulation has a long demonstrated history to be compatible with refinery operations for online use and will not harm refinery catalyst activity. Solvent-H+ is non-corrosive to steels as well as soft metals.

FQE Solvent-HW
FQE Solvent-HW is a polymer/wax dispersant and decontaminant. It is highly effective in dissolving solid hydrocarbon deposits, and various vinyl and acrylic resins typically found in vacuum tower bottoms, cat-crackers, coker fractionator bottoms, oil storage tanks, heat exchangers, and other processing equipment.
FQE Solvent-ME
FQE Solvent-ME is a water-based micro-emulsion cleaner based on award-winning FQE Solvent-H for dissolving asphaltenes, and high mole weight waxes. This product removes the need for cutter stock and a final degrease wash, leaving all surfaces left water wet.
FQE Solvent-PR+
FQE Solvent PR+ is very effective in dissolving hydrocarbon-based solids common to refinery operations such as asphaltenes, resin and various polymers (butadiene/styrene). FQE Solvent PR+ is non-corrosive to stainless steel and all soft metals and will not harm refinery catalyst activity.

Video Description

This experiment was set up to determine the efficiency of asphaltene dissolution using FQE Solvent-H versus two industry alternatives and water. As evidenced in the experiment, the soluble asphaltene was completely dissolved with vapor phase application of FQE Solvent-H. The alternatives tested essentially yielded the same results as using water (steam).

At the end of an hour, when only insoluble coke remained in the FQE beaker, a spatula was used to easily remove particulates from the beaker wall. FQE Solvent-H condensate was then transferred with the spatula to the other three beakers. The powerful active ingredients of FQE Solvent-H, in condensate, was able to solubilize the deposits in the remaining beakers.

In essence, the experiment mimics decontamination of vertical vessels using a vapor phase cleaning technique. The asphalt along the side of the beakers represent heavy fouling of vessels and process equipment, easily addressed by FQE Solvent-H. This video was shot in the FQE Chemicals Lab in Deer Park, Texas.
