OXYGEN REDUCTION SYSTEM WITH A UNIVERSALLY COMPATIBLE FRONT-END FOR COUPLING WITH VARIOUS DIFFERENT GAS SOURCES

Disclosed herein are various examples of systems, methods and devices for an oxygen reduction system with a universally compatible, adaptive front end that can be coupled with various different gas sources, wherein the oxygen reduction system determines its operations separate and independent from any signal lines from any upstream components or systems. In one example, the oxygen reduction system determines its functions, operations, and operational states from parameters that it measures from the input gas stream and other internal measurements. In this manner, installation of an oxygen reduction system is simplified, time-efficient and universal, and embodiments of the present disclosure provide for oxygen reduction systems that can be installed in a variety of different environments, applications, and with new or existing natural gas productions sites.

20200179892 · 2020-06-11 ·

A chemical plant or a petrochemical plant or a refinery may include one or more pieces of equipment that process one or more input chemicals to create one or more products. For example, catalytic dehydrogenation can be used to convert paraffins to the corresponding olefin. A delta temperature controller may determine and control differential temperature across the reactor, and use a delta temperature to control a set point for a heater temperature controller. By doing so, the plant may ramp up a catalytic dehydrogenation unit faster and ensure it does not coke up the catalyst and/or foul a screens too quickly. Catalyst activity may be taken into account and allow the plant to have better control over production and run length of the unit.
