The Haber process or Haber-Bosch process is the primary industrial method used to make ammonia or fix nitrogen. The Haber process reacts nitrogen and hydrogen gas to form ammonia: N 2 + 3 H 2 â 2 NH 3 (Î´H = â92.4 kJÂ·mol â1).
Swabbing Unit. Swabbing is a process to remove liquids from the production zone of a gas or oil well. Gas and oil wells produce fluid over the life of a well. When a well is first drilled it is usually Fracked to help open production zones. Fracking can include water. After fracking the liquids are recovered by swabbing the well. As liquids are lifted to relieve the hydrostatic weight from the producing formation the bottom-hole pressure pushes the gas and/or oil up and out of the well.
