I added Angels Refining and Petrochem to Tsm-Icons
To info.json:
"?angelsrefining",
"?angelspetrochem"
To data.lua:

local subgroup_whitelist = {"intermediate-product", "raw-resource", "raw-material", "terrain", "fill-barrel", "bob-ores","fb-material", "petrochem-carbon-synthesis", "angelsrefining", "angelspetrochem"}

But it did not add empty wagons for crystal slurry and seedlings and some other liquids

In angels it have description:

{
  type = "fluid",
  name = "crystal-slurry",
  icons = angelsmods.functions.create_viscous_liquid_fluid_icon(nil, { {105,237,038}, {211,255,052}, {100,255,000}, {147,207,47} }),
  subgroup = "ore-sorting-fluid",
  order = "c[crystal]-a",
  default_temperature = 25,
  heat_capacity = "1KJ",
  base_color = {r = 147 / 255, g = 207 / 255, b = 47 / 255},
  flow_color = {r = 100 / 255, g = 255 / 255, b = 0 / 255},
  max_temperature = 100,
  pressure_to_speed_ratio = 0.4,
  flow_to_energy_ratio = 0.59
},

So it fluid and it must be created, but it not. Please add support for Angels Refining and Petrochem and for missing liquids
