How to solve $\int_{0}^{\beta}\frac{e^{ax-\frac{b}{x}}}{\alpha-x}dx$

I'm facing with this integral in my thesis. I have 'dejavu' that I have seen this kind of integral before but I can't remember exactly. Can anyone guide me to solve this one?

$$\int_0^\beta \frac{e^{ax-\frac{b}{x}}}{\alpha-x} \, dx$$
