Title: Innovations of John J Vranicar in Natural Gas Liquefaction

Introduction

John J Vranicar is a notable inventor based in Concord, CA (US). He has made significant contributions to the field of natural gas liquefaction, holding a total of 5 patents. His work focuses on developing efficient methods and apparatuses for producing liquefied natural gas.

Latest Patents

One of his latest patents is an apparatus for the liquefaction of natural gas and methods relating to the same. This invention describes a liquefaction plant that can be coupled to a source of unpurified natural gas, such as a natural gas pipeline at a pressure letdown station. A portion of the gas is drawn off and split into a process stream and a cooling stream. The cooling stream passes through a turbo expander, creating work output. A compressor is driven by this work output to compress the process stream. The compressed process stream is then cooled, often by the expanded cooling stream. This cooled, compressed process stream is divided into first and second portions, with the first portion being expanded to liquefy the natural gas. A gas-liquid separator is employed to separate the vapor from the liquid natural gas. The second portion of the cooled, compressed process stream is also expanded and used to cool the compressed process stream. Additional features and techniques may be integrated with the liquefaction process, including a water clean-up cycle and a carbon dioxide (CO2) clean-up cycle.
