Title: Duffer B Crawford: Innovator in Hydrocarbon Processing

Introduction

Duffer B Crawford is a notable inventor based in Houston, TX (US), recognized for his contributions to hydrocarbon processing technologies. He holds a total of 4 patents, showcasing his innovative approach to solving complex challenges in the industry.

Latest Patents

Crawford's latest patents include a method for the partial condensation of hydrocarbon gas mixtures. This method involves recovering heavy components of hydrocarbon gas mixtures through partial condensation of a first portion of the starting gas by indirect heat exchange with a refrigerant. The condensate formed is entrained in the gas stream, which is then separated from the resulting partially condensed, two-phase mixture. The separated condensate undergoes thermal stripping of light components by heat exchange with a second portion of the starting gas, which is also partially condensed. This process allows for the recovery of heavy components from the starting gas mixture as stripped hydrocarbon condensate.

Another significant patent addresses the removal of mercury from gases. In this innovation, mercury is removed from natural gas by contacting the gas with a relatively mercury-free liquid state hydrocarbon. This process results in the recovery of a mercury-lean methane-rich gas and a mercury-enriched hydrocarbon liquid. The mercury-free hydrocarbon liquid can be obtained by separating mercury from the mercury-enriched hydrocarbon liquid or its derivative streams.

Career Highlights

Throughout his career, Duffer B Crawford has worked with prominent companies, including the M.W. Kellogg Company and Pullman Incorporated. His experience in these organizations has contributed to his expertise in hydrocarbon processing and innovation.
