<p>PURPOSE:To obtain a dehydration apparatus free from influence on the quality of city gas and achieving high regeneration efficiency by inserting a pressure regulation valve between an adsorbing apparatus and a spherical gas holder and keeping the pressure difference between the inlet side and the outlet side of the valve at a definite level by the regulation valve. CONSTITUTION:A pressure regulation valve is placed between an adsorbing apparatus and a spherical holder and the pressure difference between the inlet side and the outlet side of the regulation valve is controlled to a definite level between 1.5 and 2.5kg/cm<2>. The regulation of the pressure difference to a definite level is carried out by using a self-actuating governor, a governor provided with a regulation mechanism having a motor, etc., a control valve provided with a pneumatic actuator, a control valve provided with a motor, etc.</p> |
