Pressure Monitoring for Petrochemical Industry

Date: 2023-May-25

The petrochemical industry generally refers to the chemical industry that uses oil and natural gas as raw materials. It plays an essential role in the development of the national economy.

Pressure Monitoring for Petrochemical Industry

Petroleum products are involved in every aspect of human life which include kinds of fuel oil and lubricating oil obtained through processing, as well as some liquefied petroleum gas, petroleum coke and other materials. The process of obtaining such substances is called petroleum refining, or oil refining. The refining process includes multiple steps such as atmospheric distillation, vacuum distillation, hydrocracking, and refinery gas processing.

To save costs and detect changes in key indicators (pressure, flow, temperature), installing various monitoring instruments can detect abnormal conditions in the oil production process in time and take corresponding treatment measures.

Micro Sensor provides professional monitoring equipment and solutions for the petroleum refining process. It makes refining production more controllable, reduces the labor intensity of workers, and ensures production safety. Our solutions can promote the intelligent, refined and digital transformation of refinery production.

Oil and Gas Gathering

After centralized treatment of oil and gas produced by scattered oil wells, qualified products must be transported. Real-time monitoring of pipeline data parameters can be realized in gas collection and collection pipelines, crude oil transmission pipelines, pressure and temperature transmitters, vortex flowmeters, turbine flowmeters, etc.

Oil and Gas Refining and Purification

The centralized processing station, oil pressure dehydration station or gas compressor station will process crude oil and oilfield gas to produce oil and gas products that meet export standards. Temperature and pressure transmitters, mass flowmeters, vortex flowmeters, electromagnetic flowmeters and other products can be installed in dehydration and other processes. The monitoring equipment installed on the oil and gas refining system can monitor production data in real time to ensure the normal operation of refining processes such as water injection, separation, and dehydration, etc.
