Title:
PRETREATMENT EQUIPMENT FOR HYDROCARBON GAS TO BE LIQUEFIED AND SHIPPING BASE EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2017/033217
Kind Code:
A1
Abstract:
[Problem] To provide pretreatment equipment for a hydrocarbon gas to be liquefied, wherein the hydrocarbon gas containing water, hydrogen sulfide, and oxygen can be pretreated before liquefaction while reducing influences of the inclusion of hydrogen sulfide and oxygen on the pretreatment for liquefaction.
[Solution] Pretreatment equipment 101 for a hydrocarbon gas to be liquefied, wherein adsorption towers 41a and 41b have been connected to a raw-gas line 401 for supplying a hydrocarbon gas containing water, hydrogen sulfide, and oxygen and have been packed with a synthetic zeolite for adsorptively removing the water from the hydrocarbon gas. A heated regeneration gas is supplied to the adsorption tower 41a or 41b through a regeneration gas line 403 to heat and regenerate the synthetic zeolite having water adsorpted thereonto. A temperature control mechanism 43 controls the temperature to which the regeneration gas is heated, so that the temperature inside the adsorption tower during the regeneration of the synthetic zeolite is a set temperature below 230°C.
