Abstract

A drawdown compressor assembly for recovering natural gas from a gas line includes a first tubing configured for connection to a first pipe of the gas line at a one end of the first tubing. A compressor is attached to an opposite end of the first tubing and configured to draw natural gas from the first pipe through the first tubing and into the compressor for being compressed by the compressor. A second tubing is connected to the compressor at one end of the second tubing and configured for connection to a second pipe of the gas line at an opposite end of the second tubing. Activation of the compressor draws the natural gas from the first pipe through the first tubing and delivers compressed natural gas to the second pipe through the second tubing.

Abstract

Devices and methods for sewer system cleanouts such as provide increased cross bore safeguard during sewer system cleanouts. A sewer system cleanout safety device includes a housing for placement at a sewer cleanout opening to prevent passage of gas out through the sewer cleanout opening during the sewer system cleanout. The housing includes opposed inner and outer cleanout opening surfaces, and a peripheral surface extending between said inner and outer cleanout opening surfaces. The housing includes a cavity extending between the inner and outer cleanout opening surfaces to permit passage of a sewer system cleanout implement therethrough. The housing further includes a cavity lining surface to seal with the sewer system cleanout implement passing therethrough.
