VpCI®-629 series products form a persistent barrier for continuous protection against severe corrosive attacks encountered in refinery and petrochemical operations.

Effective for a wide range of refined hydrocarbons, crudes, and oil/water ratios VpCI®-629 products are highly soluble in crude oil and dispersible in fresh water and brine solutions. As a fast-acting long-term inhibitor, VpCI®-629 products form an effective corrosion inhibiting barrier for both ferrous and non-ferrous metals in the presence of water, halogens, and corrosive gases such as dissolved oxygen, sulfur dioxide, carbon dioxide, and hydrogen sulfide.

Continuing protection between treatments is assured due to solubility, dispersibility in crude water mixtures, and long-term water displacing film formation provided by VpCI®-629 products. In addition, the product provides vapor phase inhibition to protect areas inaccessible through direct solution contact. This unique characteristic protects internal parts during low fluid levels and combats atmospheric corrosion in production and storage tanks. Crude oil processing equipment, pipes and pipelines, refinery equipment and systems can be effectively protected against pitting, corrosive gases and water intrusions. Field test applications performed by independent laboratories verify that VpCI®-629 is highly effective at a concentration level as low as 5-15 ppm.
