Mud/gas separators and vacuum degasser mechanically remove entrained gases such as hydrogen sulfide, carbon dioxide and natural gas from the mud system. Entrained gas can reduce the hydrostatic head of the mud column and can cause catastrophic well control problems. Kosun manufactures both mud/gas separators and degassers. Mud/gas separators are the first units of solids control equipment arranged to treat mud. As such, they process all of the mud from the flowline before the mud reaches the primary shale shakers. The units have no moving parts and rely on the density difference between the gas and the mud for removal. The process is simple, yet very effective. Degassers are used to remove the small entrained gas bubbles left in the mud by the mud/gas separator. These units are positioned downstream from mud/gas separators, gumbo removal equipment (if utilized), shale shakers and mud conditioners (if utilized), while hydrocyclones and centrifuges follow in the arrangement. Kosun manufactures negative pressure (vacuum) and atmospheric degassers. Vacuum degassers utilize negative pressure to withdraw entrained gases from the mud. In order for this to work, mud is pumped through a venturi, which develops a negative pressure, thus sucking mud into the unit. The mud then flows over dispersion plates, arranged either horizontally or vertically, creating thin sheets of gas-cut mud. These dispersion plates bring entrained gases closer to the surface for easy removal by a stand-alone vacuum pump. The choice between horizontally- or vertically-mounted units is typically based on the footprint requirements of the specific rig. Atmospheric degassers, on the other hand, are simple in design and operation. These units mechanically remove gas, but instead of solely relying on density differences between the gas and the mud, the atmospheric degasser pumps mud into a thin layer, whereby the gas liberates itself. Usually, the desired flow rate determines the size of mud/gas separator and degasser utilized. Mud/gas separators and degassers are just a few of the many solids control and waste management offerings that Kosun supplies to the oil and gas industry. Kosun’s Quality Management System is ISO 9001-2000 certified.
