Abstract: Gasoline fuel composition suitable for use in an internal combustion engine comprising: (a) Fischer-Tropsch derived naphtha at a level from 2 to 20% v/v; (b) at least one aromatic octane booster present at a level of 0.75 to 8% v/v or less; and (c) a gasoline base fuel; wherein the gasoline fuel composition comprises 40% v/v or less of aromatics. In a preferred embodiment, the Research Octane Number (RON) of the gasoline fuel composition is increased while maintaining the aromatic content of the gasoline fuel composition at a level of 40% v/v or less, based on the gasoline fuel composition.

Abstract: A process for the recovery of ethylene glycol from an aqueous stream comprising ethylene glycol is disclosed. The process comprises (a) subjecting an aqueous stream 5 comprising ethylene glycol to an evaporation step in a multiple-effect evaporator to obtain a concentrated stream comprising ethylene glycol; (b) subjecting said concentrated stream comprising ethylene glycol to a first dehydration step in a first dehydrator 10 operating at an overhead pressure in the range of 0 barg (bar gauge) to 4 barg (bar gauge) to obtain a partially dehydrated ethylene glycol stream, and (c) subjecting said partially dehydrated ethylene glycol stream to a second dehydration step in a second dehydrator operating under 15 vacuum to obtain a dehydrated ethylene glycol stream.

Abstract: Migration of formation solids in a wellbore is restrained by feeding a slurry, comprising water, a viscosifier, and a concentration of cement clinker particles, into the wellbore, and hydrating the clinker particles in the wellbore. The clinker particles are kept in suspension during the hydrating, and upon completion of the hydrating the hydrated clinker particles form a hardened cement consisting of a permeable structure of interconnected hydrated clinker particles. A layer of degradable lost circulation material (LCM) may be employed to separate the slurry with clinker particles from the formation surrounding the wellbore during hydrating of the clinker particles.

Abstract: The present application relates to a process for producing normally gaseous, normally liquid, and optionally normally solid hydrocarbons from synthesis gas in a three-phase reactor, said reactor comprising a top middle and bottom part wherein the bottom and top part are fluidly connected via one or more reactor tubes, wherein one or more reactor tubes comprise randomly stacked catalyst bodies held stationary in the reactor tube and the reactor is at least partially filled with a liquid medium, said process comprising the steps of: (i) introducing the synthesis gas into the reactor via the bottom part; and (ii) contacting the synthesis gas with a stationary catalyst to catalytically convert the synthesis gas at an elevated temperature to obtain the normally gaseous, normally liquid, and optionally normally solid hydrocarbons from synthesis gas; (iii) withdrawing the normally gaseous, normally liquid, and optionally normally solid hydrocarbons; wherein the catalyst bodies have an open celled foam structure.

Abstract: The present disclosure describes a process for separating at least a first gas component and a second gas component by contacting a gas stream comprising the first and second gas components with a carbon molecular sieve (CMS) membrane under aggressive gas separation conditions in which the partial pressure of the selectively sorbed gas component in the gas stream is high. Despite the high partial pressure of the sorbed gas component, the selectivity of the carbon molecular sieve membrane is not substantially reduced by plasticization or saturation. In some embodiments, the aggressive gas separation process may include contacting a gas stream at supercritical conditions with a CMS membrane to separate at least first and second gas components. The process may be useful for, among other things, the separation of CO2 from a natural gas stream.
