摘要（英）：

The invention relates to a device for rectifying and producing high-purity ethylene using an ethylene heat pump, and a high-purity ethylene production technology. The device comprises a feed solution tank and a product tank. The feed solution tank is connected to a second gas-liquid separator through a first feed solution inlet of a first rectifying tower, a gas phase outlet of the first rectifying tower, a first feed gas inlet of a first heat exchanger, a first feed gas outlet of the first heat exchanger, an inlet of a first gas-liquid separator, a liquid phase outlet of the first gas-liquid separator, a second feed solution inlet of the first rectifying tower, a liquid phase outlet of the first rectifying tower, a first feed solution inlet of a second rectifying tower, a gas phase outlet of the second rectifying tower, a second feed gas inlet of the first heat exchanger, and a second feed gas outlet of the first heat exchanger, and the liquid phase outlet of the second gas-liquid separator is connected to the second feed solution inlet of the second rectifying tower and the product tank. The device has the advantages of simple technological process, stable operation, low energy consumption, safe and reliable operation, low unit power consumption, low production cost and high product purity.
