APPLICATION
The Norriseal-Wellmark experience starts with a consultation and application analysis to determine your specific needs, followed by
industry-recognized valves, controllers, regulators, switches and related accessories that offer the highest value, based on superior
quality, innovative design and competitive prices.

Natural Gas, Oil and Water Separation

Separating natural gas and water from oil is a process in which the mixture is passed through a device that removes the gas and sends it into a separate line. The remaining oil, gas and water mixture goes into a heater/treater unit. Our level controller acts to maintain the level of oil and water within the tank. Any increase beyond the set limit will then trigger the control valves to release a set amount of liquid. The gas is removed for processing and the liquid is then passed along and stored for further treatment.

Compressor Stations

The use of pipelines can be the safest and most reliable ways to transport compressed gas. However, there are many application challenges to be overcome. Compressor stations are often unmanned and safety should always be a focal point of the operation of a compressor station. High differential pressure of gases coming into the compressor station at low pressure and leaving at high pressures can create considerable noice and vibrations which must be avoided. Our valves are equipped with technologies designed to mitigate potential problems and ensure minimum leakage at a maximum efficiency level.
