A method for removing amine contaminants from both liquid and gaseous hydrocarbon streams and methods thereof are described. An additive that reacts with said contaminant to form water-soluble compounds is injected into the hydrocarbon streams.

For the purification of waste gas containing carbon compounds and nitrogen oxides by means of a regenerative post-combustion system, at least two regenerators (A, B, C) filled with heat accumulator bodies (7a, 7b, 7c) and connected by a combustion chamber (10) are provided, wherein the waste gas is alternately heated in a regenerator (A, B, C), the carbon compounds are oxidised in the combustion chamber (10), and, with the addition of a nitrogen-hydrogen compound, the nitrogen oxides are reduced in the combustion chamber (10) thermally and thus not catalytically. Remaining nitrogen oxides are removed by means of a catalytically active heat accumulator layer (6a, 6b, 6c) and the addition of a further nitrogen-hydrogen compound in the regenerator (A, B, C) from which the clean gas exits.

Systems and methods of preventing an event occurrence or mitigating effects of an event occurrence in an industrial facility are disclosed herein. In some embodiments, a first input is received from a first sensor and, based at least in part on the first input, an initial action is automatically generated. In response to the initial action, a second input is received from a second sensor and, based at least in part of the received first and second inputs, a likelihood of an event occurrence is determined. Based at least in part of the determined likelihood, a remedial action configured to prevent the occurrence of the event occurrence is automatically generated. In some embodiments, the remedial action is generated in real-time and can be directed to a process condition, environmental condition, or secondary source.

Disclosed herein are ozone reactive polymers comprising a structural repeat unit represented by the following formula XLI:

##STR00001##

wherein A is absent or a linking group selected from the group consisting of substituted or unsubstituted alkylene, substituted or unsubstituted heteroalkylene, substituted or unsubstituted cycloalkylene, substituted or unsubstituted heterocycloalkylene, substituted or unsubstituted arylene, substituted or unsubstituted heteroarylene, substituted or unsubstituted arylalkylene, and substituted or unsubstituted heteroarylalkylene; each of R.sub.1 and R.sub.2 is, independently, selected from the group consisting of hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl, substituted or unsubstituted arylalkyl, and substituted or unsubstituted heteroarylalkyl; and wherein the structural repeat unit comprises at least 10% by weight of the polymer.

A NOx control system includes a lean NOx catalyst and an alcohol generator. The lean NOx catalyst includes a substrate and a hydrocarbon selective catalytic reduction (HC-SCR) catalyst disposed on the substrate. The HC-SCR catalyst catalyzes a reduction of NOx with an alcohol. The alcohol generator generates the alcohol.

A hybrid method for capturing CO.sub.2 from a gas mixture is provided, comprising a step of contacting the CO.sub.2 containing gas mixture with a slurry consisting of a liquid medium, imidazole or imidazole derivative(s), and a metal-organic framework material (MOFs). For the slurry system, the mass fraction of the imidazole or imidazole derivative(s) in it ranging from 2 to 50% and the mass fraction of the metal-organic framework material in it ranging from 5 to 25%. In the technical solution provided in the present invention, through combining absorptive separation by the liquid solution in which the imidazole or imidazole derivative(s) is dissolved, adsorption separation by the MOF material suspended in the solution, and selective permeation separation by a liquid medium film forms on the outside surface of the suspended MOFs, an absorption-adsorption hybrid separation effect for CO.sub.2 gas mixtures is efficiently achieved. In the CO.sub.2 capture method provided in the present invention, conventional absorption separation and adsorptive separation technologies are effectively combined, furthermore, the addition of imidazole or imidazole derivative(s) substantially increases both the CO.sub.2 capture ability and capture amount of the MOFs/liquid slurry, showing a great potential in industrial applications.

The present invention provides a catalyst for purifying a combustion exhaust gas and a method for purifying a combustion exhaust gas, capable of efficiently removing a nitrogen oxide in an exhaust gas in a relatively low temperature range discharged from an internal combustion engine, such as a marine diesel engine, with a smaller amount of the reducing agent than the ordinary techniques. The catalyst for purifying a combustion exhaust gas is a catalyst used in a purification method of a combustion exhaust gas of removing a nitrogen oxide in a combustion exhaust gas by making the catalyst into contact with the combustion exhaust gas having an alcohol added thereto as a reducing agent, the catalyst containing a catalyst support containing zeolite, having supported thereon at least one metal selected from the group consisting of Ag (silver), Bi (bismuth), and Pb (lead).
