A system for emission reduction may include a housing defining a housing interior, a gas inlet configured to receive gas, a first emission reduction module comprising a first catalytic heater, and internal tubing disposed in the housing interior and configured to transport and control the gas to the first catalytic heater of the first emission reduction module.

A zero emission blow down system with an initial, high-capacity, mobile and removable platform can be positioned at a well and coupled to a wellhead. The blow down system carries a separator and a bank of catalytic heaters to react with accumulated production gas to remove the production gas without venting to atmosphere so that the well can be serviced. The blow down system can be removed from the wellhead and a subsequent, low-capacity fugitive gas remediation system can be positioned at the well and coupled to the wellhead. The fugitive gas remediation system can eliminate fugitive casing gas produced from the casing head of the well during operation. The fugitive gas remediation system has an enclosure with a separator and a catalytic heater to react with the casing gas and / or production gas.

A fugitive gas remediation (FGR) system for eliminating fugitive gas, such as surface casing vent gas produced from the casing head of an oil well, or so-called casinghead or Bradenhead gas, and other fugitive gas sources. An enclosure is positioned at a site with a fugitive gas source, such as a wellhead. A separator is located in the enclosure to remove liquid from the fugitive gas. A catalytic heater is located in the enclosure and coupled to the separator to react with the fugitive gas and produce heat in the enclosure. A pilot gas source can provide pilot gas to the catalytic heater.

The invention relates to the technical field of monitoring devices, and discloses a natural gas well mouth throttling pressure control heating production monitoring device which comprises a heat preservation box, a rainproof cap is installed on the top of the heat preservation box, an electrical assembly is installed on the left side of the heat preservation box, and an electromagnetic valve is arranged on the inner wall of the electrical assembly; a partition plate is fixedly connected to the inner wall of the heat preservation box, and a pressure control throttler is arranged between the left side of the partition plate and the inner wall of the heat preservation box.

And the rest two temperature sensors can monitor the whole area of the tubular catalytic heater with high precision in a short time, so that the monitoring device is prevented from being paralyzed immediately when a single temperature sensor II is damaged.

The present invention relates to coating compositions and methods of forming catalyst-containing coatings on substrates for catalytic heater devices. The coatings are formed by a chemical grafting method, which chemically bonds the coating (and catalysts contained therein) to the substrate. The resulting coatings have high temperature resistance and inhibit or prevent catalyst migration to the substrate, thereby maintaining catalytic activity and desired temperatures over prolonged use.

This invention belongs to the technical field of proton exchange membrane fuel cells and discloses a two-stage composite auxiliary cold start device for a honeycomb ceramic tube air-cooled fuel cell. The device includes an air supply fan, a primary heater, a secondary heater, and multiple solenoid valves. The air supply fan is located near the cathode of the cathode-cooled fuel cell to provide intake air to the primary heater. The primary heater is in the form of a resistance wire and is used to perform primary heating of the intake air. The secondary heater is in the form of a honeycomb ceramic hydrogen-oxygen catalytic heater and works in conjunction with the primary heater to perform secondary heating of the air. Furthermore, the multiple solenoid valves are used to perform different control combinations on the hydrogen supplied to the fuel cell stack and / or the secondary heater, thereby achieving operation under different conditions. This invention enables low-cost, non-destructive, cryogenic cold start and operation of open cathode fuel cell stacks, while also possessing advantages such as compact structure, ease of operation, and good adaptability.

A catalytic heater for an exhaust gas system of an internal combustion engine includes at least one electrically excitable heating element, a hydrocarbon release arrangement for release of liquid hydrocarbon toward the at least one electrically excitable heating element, and an oxidation catalyst arrangement for oxidation of hydrocarbon heated at the at least one electrically excitable heating element.

Systems and methods for reducing hydrocarbon gas emissions include the use of an emissions control system connected to a transfer station on a gas pipeline. The transfer station can be a pig launcher or a pig receiver. The emissions control system includes a transfer tank connected to the transfer station through a transfer line and a catalytic heater connected to the transfer tank through a catalytic feed line. The methods call for transferring pressurized hydrocarbon gases from the transfer station to the transfer tank, which is sized to accept a rapid transfer of a large volume of hydrocarbon gases from the transfer station. Once the gas transfer operation has taken place, the hydrocarbon gases can be more slowly processed through the catalytic heater from the transfer tank. The process can be repeated until a sufficient volume of hydrocarbon gases have been removed from the transfer station.
