What is the purpose of the GHT process?

The GHT process, or Gasoline Hydrotreating process, is primarily aimed at removing sulfur compounds from gasoline. By converting these sulfur compounds into hydrogen sulfide, which can subsequently be removed, the GHT process ensures that the gasoline meets regulatory requirements regarding sulfur content. This is essential not only for environmental reasons, as high sulfur content can lead to increased emissions when the fuel is burned but also for protecting downstream refining and distribution equipment from corrosion and fouling caused by sulfur compounds.

In contrast, the other options, while related to gasoline production, do not encapsulate the main objective of the GHT process. The focus of this specific process is primarily on sulfur removal, aligning with contemporary regulations that require low-sulfur fuels for cleaner emissions.
