What are the current compressor and process equipment used in the main MRC processes, in terms of manufacturing?

The main compressors used in current MRC (Multi-Stage Thermal Compression) processes include reciprocating compressors, screw compressors, and centrifugal compressors, while the process equipment mainly consists of separators, coolers, storage tanks, etc. The main equipment manufacturers include well-known companies such as GE, Siemens, ABB, and Atlas Copco. The advantages and disadvantages of various equipment manufacturers are roughly as follows: GE and Siemens offer compressors with stable performance and mature technology, but at relatively high prices ； ABB has a wide range of products and comprehensive solutions, but it may not be as competitive as specialized manufacturers in certain specific products ； Atlas Copco’s screw compressors enjoy a decent reputation in the industry, but may be less strong in other product lines. When selecting compressors and process equipment, factors such as the efficiency of the equipment, reliability, maintenance costs, and the manufacturer’s service support are taken into consideration. The performance of various devices depends on the specific application and the level of maintenance they receive. Generally speaking, devices from well-known manufacturers should maintain an acceptable level of performance when properly maintained. .

We produce LNG at a rate of 55,000 Nm³/h using coke oven gas, and Atlas compressors are employed for this purpose. Their price is relatively moderate, but the spare parts are expensive, especially the dry gas seals, which cost over 5 million per set; they are considered vulnerable components, and the production time in Germany is one year
