I am sure that system with scrubber that I wrote in combination with coalescer element will satisfy. Most screw compressors run over 110degC to avoid water content problem in natural or poorly refined process gas. Pressure is not so critical and also, scrubber will provide additional pulsation protection to avoid downstream vibration problems. Since flow is around 100000Sm3/h, you will require fairly big volume. There are also, packages with mechanical pre filter and a colaescer vessels so in that case just choose some MFG and think only about drain requirements (drain pump or some drain system connection). We have used some Triton coalescer elements with two filter sets in redundant. I recommend to pick some package instead of making one from scratch.
