US Patent:

7296408, Nov 20, 2007

Filed:

Sep 21, 2004

Appl. No.:

10/946228

Inventors:

Michael R. Pierce - Broomfield CO, US

International Classification:

F01B 29/10

US Classification:

60522, 60524

Abstract:

The heart of a heat engine is a reciprocating expansion chamber, which converts heat from a hot fluid into mechanical work. The expansion chamber utilizes a refrigerant in a liquid state as an input, and heats and expands the refrigerant to move pistons and generate work. A high pressure injector injects the liquid refrigerant into the chamber under enough pressure to keep it in a liquid state until it is desirable to have it expand into a gas. A hot fluid is the heat source for the expansion chamber and cold fluid is an output. Another output is the refrigerant, now a hot, low pressure gas. A compressor pressurizes the refrigerant, forming a hot, high pressure gas, and a condenser generates liquid refrigerant and provides it to the pressure injector.

Appl. No.:

12/979563

Inventors:

Michael C. Pierce - Erie CO, US

International Classification:

F25J 3/02

US Classification:

62620

Abstract:

A process and an apparatus are disclosed for recovering ethane, ethylene, and heavier hydrocarbon components from a hydrocarbon gas stream. The stream is cooled, expanded to lower pressure, and supplied to a first fractionation tower at a mid-column feed position. A distillation liquid stream is withdrawn from the first fractionation tower below the feed position of the expanded stream, heated, and directed into a second fractionation tower that produces an overhead vapor stream and a bottom liquid stream. The overhead vapor stream is cooled to condense it, with a portion of the condensed stream directed to the second fractionation tower as its top feed and the remainder directed to the first fractionation tower at a lower column feed position. The bottom liquid stream from the second fractionation tower is cooled and directed to the first fractionation tower as its top feed.
