Chlorine Dioxide Gas Applications on Environmental XPRT

Chlorine Dioxide for the Oil & Gas Industry

Chlorine dioxide (ClO2) is well suited for upstream gas production during oil and gas operations, as well as other oil and gas water applications. Chlorine dioxide is highly effective and more sustainable than other oxidizing or non-oxidizing biocide options.

Gas Detection Solutions for Hydrogen Fluoride (HF) Safety

Hydrogen Fluoride (HF) is a very useful chemical used in a variety of industries. However, HF is highly toxic with potential fatal consequences with exposure to humans, so facilities that make or use HF should exercise great care. Nevertheless, there is always the risk of leaks from process elements such as valves, pump seals and storage vessels. Tanker loading, transporting and unloading operations also provide opportunity for HF releases. Industrial processes that make or use HF typically have arrays of point sensors distributed throughout the unit. However, these sensors are maintenance intensive and have relatively slow response times. In addition, a point sensor will not detect an HF release unless it is located directly in the area of that release. Electrochemical HF sensors also respond to chlorine, ammonia, and sulfur dioxide, resulting in false alarms.

Measurement solution for liquid TiCl4 vanadium oxychloride monitor

The chloride process of titanium dioxide (TiO2) pigment manufacture first converts titania-containing ores to TiCl4 via a carbochlorination reaction at a high temperature in a chlorinator in the presence of chlorine gas and petroleum coke added as a reductant.
