What drives the cost of a LO-CAT unit?
A LO-CAT unit has three sections: • Gas treating • Catalyst regeneration • Sulfur handling The cost of the gas treating section is generally a function of gas volume and pressure. The quantity of sulfur drives the cost of the last two sections. The major operating costs of the LO-CAT unit are chemical costs and electricity. The chemical consumption is directly related to the actual amount of H2S removed from the gas stream. The power cost is largely constant when the unit is running.
