VAPOR RECOVERY SYSTEM WITH REFRIGERATION AND REGENERATION CYCLES
METHOD FOR RECOVERING METHANE FROM A SOLID CARBONACEOUS SUBTERRANEAN FORMATION
Hewitt J Paul Angleton, TX, UNITED STATES Seidle John P; Yee Dan; Puri Raje Tulsa, OK, UNITED STATES assigned to Amoco Corporation
A vapor recovery system is provided which includes a vapor recovery cycle and a regeneration cycle. The vapor recovery is condensation of the vapors in an air-vapor mixture utilizing a chiller cooled by a refrigerant gas to condense and remove vapor and to vent the air. The refrigerant a is provided cooling by compression-condensation-expansion refrigeration cycle. During the vapor recovery cycle ice tends to build up in the chiller due to the small amounts of water contained in the air-vapor mixture. In the regeneration cycle the hot refrigerant gas from the compressor by-passes the condenser and expansion valve to heat the chiller , which heats the air-vapor mixture and melts any accumulated ice. During the regeneration cycle there is no venting and the entire air-vapor mixture is recycled to the chiller until the regeneration is completed. In addition to heating and meting ice in the system, the heated air-vapor mixture may be used to dry and regenerate desiccant material in the system.
A method is disclosed for recovering methane from a solid carbonaceous subterranean formation having a production well in fluid communication with the formation and an injection well in fluid communication with the formation. In the method an oxygen-depleted effluent, produced by a cryogenic separator is injected into the formation through the injection well. A first methane-containing gaseous mixture is recovered from the formation through the production well during at least a portion of the time the oxygen-depleted effluent is being injected into the formation. The first methane-containing gaseous mixture has a first methane-desorbing gas volume percent. The injection of oxygen-depleted effluent is ceased and thereafter a second methane-containing gaseous mixture is recovered from the formation which has a second methane-desorbing gas volume percent which is less than the first methane-desorbing gas volume percent.

A lead oxide preventing apparatus for an automatic soldering device does not generate lead oxides around an impeller shaft inside a lead chamber. Industrial waste in the form of heavy-metal-contaminated material is reduced by installing a ring member and by placing an oxidation preventing agent into the ring members, or by installing a beating therein so that the molten lead does not contact portions of the impeller shaft.
An improved starting system for internal combustion engines that normally use a liquid fuel such as gasoline. Gaseous fuels such as hydrogen, natural gas, propane, butane and the like are used in place of the liquid fuel during engine starting and for a selected period thereafter. When starting is initiated, the gasoline introduction system is disabled and introduction of the gaseous fuel in initiated. Rapid engine start promptly occurs, even under very cold ambient conditions. Once the engine has started and has run for a period sufficient to reach a reasonable operating temperature, the gaseous fuel introduction system is interrupted and the gasoline system is enabled and provides the fuel thereafter. If desired, gaseous fuel flow may continue for a short period after liquid fuel flow has begun. This system improves the life of the catalytic converter and the engine, reduces hydrocarbon and carbon monoxide emissions during starting and eliminates the need for special, higher cost, gasoline mixes for winter cold starting. 166
