Condensing boilers require a drainpipe for the condensate produced during operation. Total crude oil output reached of oil and gas condensate. This condenses a large part of the gas condensate hydrocarbons. The Central North Sea comprises oil, condensate and gas fields. The field is rich in liquids and yields approximately of condensate per of gas. Typically, blended bitumen contains about 30% natural gas condensate or other diluents and 70% bitumen. Other common dilutants include natural-gas condensate, and light crude. There are two types of dehumidifiers - condensate dehumidifiers and desiccant dehumidifiers. Purity was improved by further distillation of the condensate. In 2007, Texas state waters produced of oil and condensate and gas. In addition, there are factories&colon; gas processing, stabilization of condensate, motor fuel. "Skarv" is a gas condensate and oil field development. The Air Receiver collects condensate and minimises pressure drop. Cogeneration plants face possible contamination of returned condensate. The liquid component was known as "condensate".
