摘要：在石油生产制造过程中，加氢精制是一个重要的步骤。然而传统的往复式压缩机气量调节方式浪费能源，控制速度缓慢。现采用HydroCOM控制技术实现气量的无级调节，压缩机根据实际需要的气量进行压缩，从而能够最大限度的节约能源，实现了传统的常规控制无法达到的控制功能。本文详细阐述了HydroCOM控制系统的基本工作原理及组成结构，嵌入在CS3000控制系统中，最终实现对气量的无级控制。采用HydroCOM系统后，节能效果显著，能够有效地实现节能降耗、减亏增效的目的。结合其在实际应用中展现的良好的节能效果，证明HydroCOM是一种值得广泛推广的先进技术。

Abstract： In the petroleum production process, hydrogenation is a very important step. However, the traditional way of regulating the reciprocating compressor wastes energy and has slow control rate. HydroCOM control technology now is used to realize the stepless regulation of the gas compressor according to the actual needs of hydrogen, achieving the maximum energy saving while the traditional control methods could not reach the same control function. The basic working principles and structure of the HydroCOM system are described in this paper. This system is embedded in the CS3000 control system and ultimately accomplishes the stepless control of hydrogen. Using HydroCOM system, the energy-saving effect is remarkable. It is also effectively achieve the purpose of reducing loses and improving efficiency. Combined with its outstanding practical application results in the field of energy-saving, HydroCOM system is an advanced technology which should be widely introduced.
