STALWOL PPD

Pour Point Depressant

This additive is a polymer designed to interfere in the wax crystallization process, thus modifying the crystal structure of the paraffin present in the crude oil. The change in the crystal shape diminishes the ability of waxy aggregates to inter grow and inter lock, resulting in lowering the pour point of the crude.

STALWOL PWD

Paraffin Wax Dispersant

This additive is a liquid, organic surface active chemical for use in crude oil to control the deposition of paraffin.The oil soluble and water dispersible formulation is effective in removing and preventing paraffin build up in production equipment.

STALWOL AD

Asphaltene Derivatives

The asphaltene in nature is stabilized by resins and maintained in the oil due to this stabilization. Asphaltene dispersants substitutes the natural resins do not allow the asphaltene articles to form bigger size molecules and deposit. It is based on polymeric technology with multiple anchoring groups and has chains that are compatible with the crude oils.

STALWOL DC

Demulsifier Concentrates

Demulsification of water from water in oil emulsions and removal of the water economically meeting the technical requirements of the oil for further processing is a critical operation. Demulsifiers tend to act on the emulsion by:

- Coalescence of the water droplets

- Dropping of the water.

STALWOL RE

Deoiler/Reverse Emulsifier

This additive is a remove free/ emulsified oil from separated water in oilfields.

STALWOL CI

Corrosion Inhibitors

This additive gets adsorbed on the metallic surface, protecting the metal surface by forming a film, giving the surface a certain level of protection.

STALWOL HS

H2S Scavengers

These tie up with the H2S in an irreversible reaction preventing the release and thus reduces corrosion leading to improved safety. These products are designed to control H2S with bubble tower applications and/or continuous injections into the wellhead, infield or other transmission lines.

STALWOL SI

H2S Scavengers with scale inhibitor

This product is formulated lo give excellent H2S Scavenging characteristics with scale inhibition. It features an instantaneous reaction with hydrogen sulfide and is very effective even allow dosage rates. It effectively controls the scaling problem without any negative impact on downstream operations.

STALWOL BAC

Biocide

This is a Benzalkonium Chloride based Microbiocide and is used for effective control of aerobic and anaerobic bacteria in the oilfields as well as in various other applications. It prevents formation of sulphurous gases and inhibits corrosion and biofouling in pipelines.

STALWOL AF

Defoamers/Antifoam

An effective way to disrupt foam formation is to introduce a foam control surfactant into the system. A defoamer or antifoamer functions by spreading over the gas/liquid interfaces, thereby preventing foam forming materials from coming to the surface and providing a surface layer which will not sustain foam.

STALWOL SB

Sludge Breakers

This additive rapidly dissolves and fluidizes sludge, wax, gum and tar formations while effectively separating water from oil/water emulsions.

STALWOL MS

Mutual Solvents

This additive prevents/ break emulsion block formation in the invasion zone in an oilwell. It intern increases crude flow from the formation.
