The present invention relates to a gas-separating membrane module comprising heat conductive panels, which allows direct temperature control of the membrane surface, even in multiple zones.
The present invention relates to a multi-functional additive mixture containing reduced unsaturated detergent dispersant (DD) components and to a process for its preparation, which comprises reaction products of polyisobutylene succinic acid anhydride derivatives. anti-friction and anti-wear, increases viscosity and viscosity index, anti-oxidatative and has an acid-neutralizing effect, and is therefore preferably used to improve the properties of lubricating oils, motor fuels, system cleaning fluids and aqueous emulsions and suspensions containing hydrocarbons.
The method of the subject matter innovation is used for detecting leaks in pipelines carrying a flowing medium.
The present invention relates to cocogem surfactants for an enhanced oil recovery process, said surfactants exhibit reduced critical concentration for micelle formation and thermal stability under conditions typical of deeper oil storage layers (e.g. higher temperature, pressure and/or salinity) as compared to the prior art.
The present invention relates to a composition for an enhanced oil recovery process, said composition comprising (a) one or more anionic cocogem surfactants; b) one or more surfactants based on nonionic vegetable fatty acids (or their synthetic analogues); c) optionally one or more, preferably commercially available, co-surfactants; d) optionally one or more agents with phase transfer property, preferably an alcohol; and e) polyacrylamide as a flow modifier.
