【 摘 要 】

In order to investigate the wax inhibition performance of various inhibitors different scanning calorimetric (DSC), a powerful and quickly technique having no request of sample pretreatment, has been used for investigation the thermal characteristics of the wax remover. According to the parameters such as wax appearance temperature (WAT), content of wax and rheology, it is found that the best wax removing rate can be reached to 457mg/L•h under 40 C with 150mg/L surfactant combination (fatty alcohol polyoxyethylene ether + calcium petroleum sulfonate + mixed alcohol).
