一、脱水工艺流程简介TEG(三甘醇)湿法脱水具有工艺流程简单、脱水效果较好、操作费用较低及TEG可以循环使用的特点。吸收了水分的TEG富液经过换热、闪蒸、过滤进入再生釜加热再生,再生完后贫液再经过换热、冷却增压至脱水塔,完成溶液的脱水、再生循环。再生釜一般用产品气作为热源,再生期间在再生釜内通入产品气作为汽提气,降低重沸器气相中的水汽分压,提高TEG的 First, the dehydration process Introduction TEG (triethylene glycol) wet dehydration with a simple process, better dehydration, lower operating costs and TEG can be recycled. The TEG rich liquid that has absorbed moisture is heat-exchanged, flashed and filtered into the regeneration kettle for heating and regeneration. After the regeneration, the lean liquid is subjected to heat exchange and cooling and pressurization to the dehydration tower to complete the dehydration and regeneration cycle of the solution. Regeneration tank product gas as a general source of heat during the regeneration of the product gas pass into the regeneration vessel as a stripping gas to reduce the water vapor partial pressure of the reboiler to improve the TEG
