The nozzle loads appear to be quite high.
Morever it is not clear how much is the overall pipe length in the horizontal direction for locating the rest support. The vertical length of 3.8m has a dead load (empty) of 500 kg. overall considering even the horizontal length dead load . the load does not appear too much .
Hence the rest support looks okay unless it is located beyond the permissible span.

Subject: [SOCIAL NETWORK] [MW:29849] vertical vessel piping _first rest support
Dear all,
Please find the below, sulfur absorber vessel, The following pipe mtl is A335 P11 and thk. = 14.27mm. The vertical portion is 3.8m only, immediately on the rack we have rest support
If the vertical portion is long i.e if it about 15m and above, we have to provide rest support either rigid or spring in vertical portion.
As per below snap small vertical vessel and the pipe size 12" sch 60 we have more span. Providing support and if not in the vertical portion doesnt impacting the nozzle loads. The nozzle loads are Fx=Fy=Fz=18Tons and Mx=15tons, My=Mz=7tons. In my point of view first rest support is not required in this case, kinldy share your opinions
