Description

P a t e n t k r a v 1. Bionedbrydelig kemisk sammensætning med styret frigivelse, der omfatter en partikelformig stivelse og mindst ét kemikalie. 2. Sammensætning ifølge krav 1, hvor den partikelfomnige stivelse er en granulær stivelse. 3. Sammensætning ifølge krav 1 eller 2, hvor kemikaliet er et kemikalie til oliebrønd. 4. Sammensætning ifølge krav 3, hvor kemikaliet til oliebrønd er valgt fra gruppen bestående af friktionsreducerende midler, korrosionsinhibitorer, voks- inhibitorer, hydratinhibitorer, gel brydere, sporstoffer, overfladeaktive midler, skælinhibitorer, antiskumningsmidler, demulgerende midler, flydepunkt- nedsættende midler, biocider, slæbreducerende midler, antioxidanter, hydrogensulfiduddrivningsmidler, oxygenuddrivningsmidler, oliefjemende midler og asfalteninhibitorer. 5. Sammensætning ifølge et hvilket som helst af de foregående krav, hvor stivelsen er tæret. 6. Sammensætning ifølge et hvilket som helst af de foregående krav, hvor stivelsen er hydrofobmodificeret. 7. Sammensætning ifølge krav 6, hvor stivelsen er stivelseoctenylsuccinat. 8. Sammensætning ifølge et hvilket som helst af de foregående krav, hvilken sammensætning yderligere omfatter et supplerende stof valgt fra gruppen bestående af et blødgøringsmiddel, et overfladeaktivt middel, et fyldstof, et chelateringsmiddel, et fortykningsmiddel, et partikelformigt stof, gelatine, gummi arabicum, zein, sojaprotein og polymerer/copolymerer af polyethylen og polyvinylchlorid. 9. Sammensætning ifølge et hvilket som helst af de foregående krav, hvor stivelsen er valgt, så den frigør kemikaliet ved en udvalgt temperatur. 10. Sammensætning ifølge krav 9, hvor stivelsen er valgt, så den frigør kemikaliet ved 60 °C. 11. Fremgangsmåde til fremstilling af sammensætningen ifølge et hvilket som helst af de foregående krav, hvilken fremgangsmåde omfatter a. blanding af en partikelformig stivelse med et kemikalie til dannelse af en blanding; og b. behandling af blandingen til dannelse af et fritflydende, ikke-klæbrigt pulver, forudsat at behandlingen tillader, at stivelsen i pulveret bibeholder sin partikelformige struktur. 12. Fremgangsmåde ifølge krav 11, hvorved behandlingen omfatter at omrøre formuleringsblandingen ved omgivende temperatur og tryk, indtil der er opnået et fritflydende, ikke-klæbrigt pulver. 13. Fremgangsmåde ifølge krav 11, hvorved behandlingen er valgt fra gruppen bestående af termisk batchbearbejdning under vakuum, rullekomprimering, bearbejdning i fluidiseret leje, spraytørring og ekstrudering. 14. Fremgangsmåde ifølge et hvilket som helst af kravene 11-13, hvorved blandingen yderligere omfatter et supplerende stof valgt fra gruppen bestående af et blødgøringsmiddel, et overfladeaktivt middel, et fyldstof, et chelateringsmiddel, et fortykningsmiddel, et partikelformigt stof, gelatine, gummi arabicum, zein, sojaprotein og polymerer/copolymerer af polyethylen og polyvinylchlorid. 15. Sammensætning, der omfatter en blanding af mindst to sammensætninger i overensstemmelse med et hvilket som helst af kravene 10, hvor kemikalierne er uforligelige med hinanden.
