CorroLogic® VpCI®-637 TOL

Product Description

VpCI®-637 TOL provides corrosion control in natural gas and crude oil gathering and trxansmission lines, including the difficult Top-of-Line (TOL) corrosion problems.

VpCI®-637 TOL is a combination of vapor phase and filmforming corrosion inhibitors. It is particularly useful in combating the corrosion caused by condensation of acidic vapor in areas inaccessible by direct contact. It also provides excellent protection to Bottom-of-the-Line (BOL) corrosion caused by corrosive fluids. VpCI®-637 TOL is able to partition through hydrocarbon to reach aqueous phase, and to function in a variety of flow reigns.

The unique chemistries of VpCI®-637 TOL enable the product to protect internal pipelines in “sweet/sour” saturated carbon dioxide/ hydrogen sulfide environment.

Features

• Effective for a wide range of systems and corrosive conditions  
• Provide maximum control over long distances for highly corrosive systems with a high water-to-hydrocarbons ratio, including TOL and low areas in systems where water collects and extreme corrosive attack occurs  
• Particularly effective in mitigating the corrosion caused by condensation of acidic vapor in areas inaccessible by direct contact  
• Forms an adsorbed, protective layer that protects ferrous and non-ferrous metals
• Effective against water, corrosive gases, and halogens  
• Vapor phase action provides protection from atmospheric conditions and moisture condensation to areas not accessible by filming inhibitors  
• Does not contain heavy metals, chlorinated hydrocarbons, or volatile amines  
• Does not negatively affect water/fuel separation property in the processed fuel products

Typical Applications

VpCI®-637 TOL is designed for use in natural gas pipelines and petroleum recovery processes, most effective in situations prone to TOL corrosion attacks.

Method of Application

VpCI®-637 TOL is best applied by continuous injection or atomization into the transmission line. Atomization of the product into the gas stream enhances the dispersion and length of travel. Generally, dose rate of 10-30 fl oz (300-900ml) of the product per million cubic feet of gas is sufficient for the majority of applications.

Packaging and Storage

VpCI®-637 TOL is available in 5 gallon (19 liter) containers, 55 gallon (208 liter) metal drums, liquid totes, and bulk. Products should be stored in tightly closed containers.
