PUMPS & VALVES | By David Morrow Reducing the risk of handling hazardous high-value chemicals Dry disconnect coupling system improves safety and bottom line B utadiene. Xylene. Toluene. Sul- furic acid. Potassium hydroxide. Even the names of these haz- ardous chemicals sound danger- ous. In addition to potentially harming the health of humans and the environment if mishandled, they have another thing in common: they are very expensive to produce. That’s why manufacturers, processors, shippers and distributors of highly haz- ardous, high-value chemicals enter into a tacit agreement with their employees and the environment: these incredibly volatile and valuable fluids must be handled with the utmost care, from the manufactur- ing plant through the railcars and tanker trucks that ship them and the bulk-storage facilities that house them, to avoid any potential damage or harm. Serving Customers Better For 25 Years And Counting Hi-Tech Seals was founded in Edmonton, Alberta, on the principle of providing superior value to our customers by way of supplying quality products that are delivered on time, at a competitive cost. Our products are backed by a knowledgeable team of sealing professionals who, in combination, have over 900 years of sealing experience. A key link in the chemical-pro- cessing supply chain is the equipment that is used to facilitate the transfer of volatile chemicals from the manu- facturing facility to transport vehicles and then to the storage terminal. For years, the accepted technology for the dry disconnect couplings that would enable the connection of hoses to stor- age tanks and transport vehicles has featured a poppet-style design. POPPETS MAY COMPROMISE SAFETY The use of poppets, however, can compromise safety and create potential Hi-Tech Seals’ would like to take this time to thank all of our customers for their continued support and business over the years. We look forward to serving you in the coming years. < Figure 1. < Figure 2. 22 Oil & Gas Product News MAY/JUNE 2016 problems for the handler who is look- ing to ensure the safety of employees and the environment because the shape of the poppets inside the coupler hous- ing form areas where chemicals can nest, meaning that there will always be the possibility that some type of prod- uct spill can occur when the couplings are disconnected. This is not a big issue if the fluid being handled is non-haz- ardous and inexpensive, but a potential problem when handling hazardous and high-value fluids.
