A phosphorus-containing flame retardant is produced by reacting at a reaction temperature a mixture including a metal or suitable metal compound and a stoichiometric excess relative to the metal or suitable metal compound of an unsubstituted or alkyl or aryl substituted phosphonic or pyrophosphonic acid, wherein the phosphonic or pyrophosphonic acid is in a molten state at the reaction temperature. The chemical composition of the resulting flame retardant product leads to excellent flame retardancy and exhibits high thermal stability. The presently disclosed flame retardants are useful, for example, in polymer compositions, particularly thermoplastics processed at high temperatures, over a wide range of applications.

The present disclosure provides processes for removing hydrocarbons, oil coated solids, and suspended solids from a separated water stream produced from a produced water source. In particular, the methods comprise subjecting the separated water stream to a centrifugal separation followed by filtration.

Flame retardant material comprising a compound of empirical formula (III) wherein R is H, an alkyl, aryl, alkylaryl, or arylalkyl group; M is a metal and y is 3, such that Mis a metal cation where (+)y represents the charge formally assigned to the cation; a, b, and c represent the ratio of the components to which they correspond relative to one another in the compound, and satisfy a charge-balance equation 2(a)+c=b(y); and a and c are not zero. The presently disclosed flame retardants are useful, for example, in polymer compositions, particularly thermoplastics processed at high temperatures, over a wide range of applications.

A method and system generate steam for SAGD operation wherein steam generator blowdown water is acidified, cooled and clarified before reuse. Acid Clarification Treatment, or 'ACT', mitigates organic fouling in Once-Through Stream Generators. Lab tests quantitatively and qualitatively show that ACT reduces Total organic carbon (TOC) and 'bad actors' TOC, respectively, in blowdown streams.

A new water treatment system for SAGD operations is disclosed. Instead of treating both produced water and recycled water using warm lime softening systems, the recycled water is combined with saline water in a cold lime softening system. This results in slightly warmed reactions that require less chemicals during the lime softening process while also allowing for larger volumes of treated produced water to be generated by the warm lime softening system.

Small footprint, portable skid mounted wellhead desander systems are disclosed. In one version, two systems are mounted on the skid, one system being a single well system for testing various properties of well fluids, and the other being a combined bulk system for desanding comingled flow from a plurality of wells. In another version, the skid mounted system has three independent desanders together with all essential equipment, including e.g., plug catcher, hydrocyclone desander, solids accumulator, choke manifold, and all necessary sensors, valving and control equipment.
