Abstract: An esterification process and the products resulting from it which achieves a mixture of secondary esters which are effectively used with invert drilling muds, the process involving the addition of one or more C.sub.1 -C.sub.5 carboxylic acids and one or more C.sub.3 -C.sub.22 olefins in the presence of an acid catalyst.

Abstract: The present invention relates to synthetic hydrocarbons produced by skeletal isomerization, and the isomerization process. The products are especially useful as the continuous phase of a drilling fluid, for example when prepared from C.sub.14 to C.sub.18 linear alpha-olefins via isomerization or hydroisomerization, and as lube oils.The present invention also relates to a process for producing synthetic hydrocarbons by skeletally isomerizing C.sub.12+ olefins over a catalyst comprising an intermediate pore size molecular sieve, with or without Group VIII metals under skeletal isomerization conditions which result in little, preferably in substantially no, olefin cracking or oligomerization.

Abstract: A process for removing oily residues from aqueous waste streams using a cross flow filtration system in which the efficiency of a dynamic membrane system comprising a gel layer and supporting semipermeable membrane is optimized by applying a controlled shear force parallel to the plane of the membrane.
