Abstract: 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.

Abstract: A portable combination gas and wood fire pit device comprises a spark screen disposed over a fire bowl and a grating disposed across an open top of the fire bowl. A gas burner is disposed in the fire bowl and below the grating. A cover plate is disposed over the gas burner and spaced above the gas burner to cover an open cup and neck of the gas burner from above. The spark screen has a cylindrical shape with vertical side wall extending above the fire bowl and a solid section and a mesh section. The solid section has interior and exterior perimeters forming a silhouette or stencil defining an object comprising at least: an animal, a person, a landscape, or combinations thereof.
