Scrubber controls storage tank vent emissions
Bionomic Industries’ VentClean system is designed for the scrubbing of storage tank vent emissions caused by tank breathing and filling operations. It can handle single as well as multiple storage tanks with large variations in venting rates, while a low pressure drop design prohibits dangerous over-pressurization in both glass fibre and plastic storage tanks. A standard system handles gas capacities from 0 acfm to 100 acfm (an optional version handles up to 200 acfm) with removal efficiencies over 99%. Two configurations are available: one uses water on a once-through basis and the other incorporates a circulation pump that uses water at a reduced consumption rate, or a chemical reagent such as sodium hydroxide on a recirculated batch basis. Typical applications include removal of acids, alcohols, formaldehyde, amines and almost any other water-soluble contaminants.

Technical leaflet details synergistic coating for titanium alloys
A technical data sheet from General Magnaplate explains how titanium alloys can be coated using Canadize to increase the metals’ abrasion resistance, wear life and resistance to corrosion and chemical attack. These synergistic coating processes preclude any hydrogen absorption, to which titanium is highly susceptible. The multi-step process combines the advantages of anodizing or hard-coat plating with the controlled infusion of low-friction polymers and dry lubricants. The result is a surface which is superior in performance to both the base metal and the individual components of the coatings, thus alleviating the problems of wear, friction, galling, seizing, moisture and corrosion across a wide range of applications. The leaflet details the product’s technical data and performance characteristics.
