    摘要： Included is a method of starting up a direct heating device having a fuel introduction zone, a combustion zone and a process zone that is in heat exchange relationship with said combustion zone. Prior to the introduction of a fuel fluid into said combustion zone, an oxidant fluid, having a high temperature, is passed through the combustion zone for a warm-up time period sufficient to raise the temperature of the direct heating device to a desired temperature. Steam or a process fluid is passed through the process zone followed by the introduction of a fuel fluid into the fuel introduction zone. After the device has been heated up a process fluid is introduced through the process zone. Thereafter, the introduction of steam through the process zone may be stopped.

    摘要： The invention provides a process and a reactor for the preparation of an alkylene glycol from an alkylene oxide. Alkylene oxide, water, a homogeneous carboxylation catalyst and a homogenous hydrolysis catalyst are supplied to a reactor comprising a carboxylation zone and a hydrolysis zone. One or more ejectors are used to mix carbon dioxide and the liquid reagents in the carboxylation zone so that alkylene oxide reacts with carbon dioxide in the presence of water in the carboxylation zone to form a reaction solution comprising alkylene carbonate, water, the homogeneous carboxylation catalyst and the homogeneous hydrolysis catalyst. The reaction solution is supplied from the carboxylation zone to a hydrolysis zone, wherein alkylene carbonate and water react to form a product solution comprising alkylene glycol, the homogeneous carboxylation catalyst and the homogeneous hydrolysis catalyst. Carbon dioxide released by the reaction of alkylene carbonate and water in the hydrolysis zone is supplied to the carboxylation zone. Product solution is withdrawn from the hydrolysis zone.
