Sealing Solutions to the Rescue

By Joy LePree |

Improved seals, gaskets and valve packings stand up to tougher process conditions Chemical processors expect more from their seals, gaskets and valve packings than ever before, as sealing components must meet tighter and stricter regulations regarding emissions, stand up to tougher process conditions and perform for greater lengths of time in the extreme sealing environments of the chemical process industries (CPI). Failure of sealing elements is not tolerated because the impact can be costly and catastrophic.   Sealing challenges According to industry experts, there are several significant challenges facing chemical processors and their sealing applications. The first major concern is an ever-decreasing allowable limit on emissions. While methane is a hot-button issue for the petroleum refining industry at the moment, there is a general emphasis on the reduction of hydrocarbons, volatile organic compounds (VOCs) and greenhouse gas (GHG) emissions throughout the CPI. “Right now there is a major focus on the proposed reduction of methane emissions in the oil-and-gas sector, but there is a general emphasis from the [U.S.] Environmental Protection Agency (EPA; Washington, D.C.; www.epa.gov) on VOC emissions, as well,” notes…
