摘要： A cost effective method for revamping a low pressure distillate hydrotreating process unit to a high pressure distillate hydrotreating process unit. A high pressure hot-feed pump is added, the furnace is retubed for higher pressures, the low pressure reactor is replaced with a high pressure reactor, a high pressure let-down valve is added at the reactor outlet, and the low pressure recycle compressor is replaced with a high pressure recycle compressor.

摘要翻译： 将低压馏出物加氢处理装置改造成高压馏出物加氢处理装置的成本有效的方法。 加入高压热水泵，将炉子再压入高压，低压反应器用高压反应器代替，在反应器出口加入高压降压阀，低压循环压缩机 用高压循环压缩机代替。
