Abstract

"MéTODO PARA REMOVER, OU EVITAR, OU INIBIR A DEPOSIçãO, EM UM POçO, DUTO OU VASO, DE ASFALTENOS E/OU CERAS DE PETRóLEO". A deposição de asfaltenos e/ou ceras de petróleo pode ser inibida e/ou asfaltenos e/ou ceras de petróleo podem ser removidos de um poço, duto ou vaso por contato do asfalteno e/ou cera de petróleo ou o duto do poço ou vaso adjacente a um local onde a deposição de asfalteno e/ou cera de petróleo é esperada, com um solvente incluindo, pelo menos, um composto de fórmula (I): R^ 1^-(AO)~ n~-OOC-(CH~ 2~)~ m~-Ph-(R^ 2^)~ p~, onde R^ 1^ é um grupo hidrocarbila C~ 1~ a C~ 20~; AO é um grupo alquilenóxi e pode variar ao longo da cadeia (poli) alquilenóxi; n é 0 ou de 1 a 100; m é 0,1 ou 2; e Ph é um grupo fenila, que pode ser substituído com grupos (R^ 2^)~ p~, onde cada R^ 2^ é independentemente um grupo alquila C~ 1~ a C~ 4~ ou alcóxi; e p é 0, 1 ou 2, e subseq³entemente removendo o solvente com asfaltenos e/ou ceras de petróleo amolecidos, dissolvidos ou dispersos do poço, duto ou vaso.,
