After the melting cavity of the salt cavern gas storage in Jiangsu Jintan gas storage is completed, gas injection and brine removal operations are required. During this process, the compressor displacement is about 300,000 standard cubic meters per day, and the gas injection compression for the Jintan gas storage The exhaust capacity of a single machine is about 1.5 million standard cubic meters per day. If another compressor with a small displacement is installed, it will inevitably increase a lot of costs. Therefore, how to use the existing equipment conditions of the gas storage to adjust the displacement of the compressor and improve the economic benefits of gas injection and brine discharge has become the focus.
Four departments including the National Development and Reform Commission and the National Energy Administration have formulated the "Regulations for the Fair Opening of Oil and Gas Pipeline Network Facilities", which re-emphasizes the opening of pipeline network facilities, and emphasizes the use of natural gas calorific value measurement by pipeline network operators, and gives Date requirements, Article 13 of the original text: When natural gas pipeline network facility operators receive and deliver natural gas to users on behalf of natural gas production and sales companies, they shall scientifically measure the calorific value, volume, and quality, and accept the government's administrative department for measurement. Metrological supervision and inspection. The State promotes natural gas energy measurement and pricing, and establishes a natural gas energy measurement and pricing system within 24 months from the date of implementation of these Measures.
In order to solve the problem that the gas transmission volume of long-distance natural gas pipelines varies greatly in different seasons, which makes the filtration and separation equipment often deviate from the design conditions, and causes excessive damage to the centrifuge dry gas seal filtration and separation filter element, Prehot Energy serves well-known universities in the United Nations, By rationally optimizing the multi-tube cyclone separator, the combination of the cyclone separator and the filter separator is reasonably matched, so that the filter separation equipment can realize the optimized operation of the filter separation equipment under different pressure and flow conditions, which greatly delays the use of the dry gas seal of the centrifugal compressor Life span has realized cost-saving and efficiency-increasing effects for customers' production and operation.
Based on years of experience in oil and gas services, combined with the current market’s advanced technology, Prehot Energy Services has continuously innovated fully automated and intelligent management for new/old natural gas stations. Based on the new technology concept of Prehot Energy, it has successively made the first CNG mother station Jimo Station, Zhongyuan Oil Field Wenliu Boosting Station, Wener Joint Station, CNOOC Jinzhou Offshore Platform and other projects have proposed intelligent and automated system upgrade solutions, and successfully completed the entire system or sub-system with the strong support of customers The upgrade of the system reduces the risk of safety production and improves the efficiency of production management.
