Materials and speed of reciprocating compressors
Thread Content
We need to buy a compressor with 40% hydrogen, 10% each of carbon monoxide and carbon dioxide, and hydrogen sulfide levels below 50 ppm. What materials should be used for the cylinders, cylinder liners, pistons, etc.? For an water content of less than 1%, the flow rate should be between 50% and 110% – can variable speed control be used? What material to use? The water content is less than 1%. Please give me some advice! Is variable speed control available to achieve a flow rate of 50% to 110%?
Sure, a continuously adjustable system will do.
It seems that variable speed control is rarely used for flow regulation in reciprocating compressors. Is it because frequency conversion of the motor is not cost-effective?
Your questions are all answered in API618! Variable frequency is not recommended. Common load regulation methods include unloading devices, clearance volume, and stepless adjustment; a decision should be made by considering the changes in load along with the investment costs.
