How methanol prevents hydrates
WebRequiring lower dosage rates than traditional methanol or glycol based inhibitors, This LDHI prevent hydrate plugs that can create complete blockages, improving health, safety and environmental (HSE) performance by reducing chemical storage and handling hazards associated with thermodynamic inhibitors such as methanol and glycols. WebOur laboratory may propose several analytical tools (XRPD, DSC, SEM, etc.) and R&D support to help you managing your solid-state issues during drug developement. Since 2016, I am also operationnal manager (and adviser for Crystallization sector) at the Institut Carnot I2C which provides applied science and chemistry skill to industrial companies.
