Abstract
Abstract In a degasifier for the separation of gases and vapors from gas-liquid and vapor-liquid mixtures flowing through a pipeline there is provided at the bottom of a housing a pipe section connected into the pipeline with a branch conduit connected to the top of the pipe section and extending upwardly therefrom for the delivery of gas or vapor-laden liquid mixtures to the upper part of the housing. The pipe section has bottom openings for the return of liquid discharged through the branch conduit and liberated from the gases or vapors to the pipe section and the pipeline.

Total Claims: 8
Claim 1
Independent Claim
127 words
A degasifier for the separation of gases and vapors from gas-liquid and vapor-liquid mixture streams within a pipeline, comprising: (a) a housing; (b) a pipe section extending across said housing and having means for connection in said pipeline, said housing having a cross-section substantially larger than said pipe section; (c) an upwardly projecting branch conduit connected to said pipe section for the delivery of gas or vapor-liquid mixtures from said pipe section to the interior of said housing; (d) said pipe section having openings providing for communication with the lower part of the housing interior for the return of the liquid from said housing interior to said pipeline; and (e) said housing having a cover arranged in spaced relationship above a top opening of said branch conduit.
Claim 2
Dependent Claim
127 words
A degasifier for the separation of gases and vapors from gas-liquid and vapor-liquid mixture streams within a pipeline, comprising: (a) a housing; (b) a pipe section extending across said housing and having means for connection in said pipeline, said housing having a cross-section substantially larger than said pipe section; (c) an upwardly projecting branch conduit connected to said pipe section for the delivery of gas or vapor-liquid mixtures from said pipe section to the interior of said housing; (d) said pipe section having openings providing for communication with the lower part of the housing interior for the return of the liquid from said housing interior to said pipeline; and (e) said housing having a cover arranged in spaced relationship above a top opening of said branch conduit.
Claim 3
Dependent Claim
38 words
A degasifier according to claim 1, wherein said pipe section is disposed directly above the bottom of said housing and said openings are formed in the lower side walls of said pipe section directly adjacent the housing bottom.
Claim 4
Dependent Claim
22 words
A degasifier according to claim 1, wherein the openings in said pipe section are arranged below, and upstream of, said branch conduit.
Claim 5
Dependent Claim
22 words
A degasifier according to claim 2, wherein the openings in said pipe section are arranged below, and upstream of, said branch conduit.
Claim 6
Dependent Claim
51 words
A degasifier according to claim 1, wherein said housing has a gas discharge nozzle in the upper part thereof and a float is provided in said housing and has a valve head associated therewith so as to close said discharge nozzle when the liquid in said housing reaches a predetermined level.
Claim 7
Dependent Claim
72 words
A degasifier according to claim 1, wherein said housing has a gas discharge nozzle in the upper part thereof remote from said branch conduit and a droplet separator extends across the upper part of said housing from said cover downwardly into the liquid in the lower part of said housing such that any gases or vapors discharged from said branch conduit need to pass through said separator before entering said discharge nozzle.
Claim 8
Dependent Claim
12 words
A degasifier according to claim 1, wherein said housing cover is arched.
